1.0 Department Procedures
Section 1 outlines steps followed by the City of Tampa Water Department ("Department" or “City”) when processing a Developer’s project. Because a project may have specific non-standard conditions, the City may direct additional requirements beyond the specifications identified in this Manual.
A Developer Project is defined as one wherein a non-Department entity applies for and obtains water service from the Department.
Various forms, documents, and engineering data needed to complete the required Utility Service Application, Commitment for Service, and Construction Plan Review processes can be found within this Manual and on the Department’s web site at https://www.tampagov.net/water.
1.1 Generalized Customer-Initiated Project Workflow

1.2 Water Service Application Requirements
1.2.1 When a Utility Service Application is Required
Each domestic meter and location/address requires a separate utility application.
The following address types may be issued a water service commitment:
- Current Location Point
- Current Master Point
- Current Utility Point
- Current Project Point
- Current Parcel Point
Please contact the Planning and Development Department, Land Development Coordination Division for address related questions.
Residential Projects (Fewer than 3 units)
Listed below are general guidelines for determining when the submittal of a Utility Service Application is required for a residential project.
Residential projects that do require submittal of an application for Water and Wastewater service are as follows:
- Knockdown / Rebuild
- New construction of a residential building
- Private well to City water conversion
- Any activity that needs a new water meter
- Relocation of a water meter
- An existing residential building which has not been associated with an active account for five (5) years or more
- A new fire protection system is proposed OR an existing fire protection system is proposed to be modified; a fire protection system is considered to be modified when an additional area is protected or a greater density of sprinkler heads is to be provided. Maintenance or rehabilitation activities, such as replacing or relocating fire sprinkler heads, is not considered a modification for the purposes of determining if a Utility Service Application is required.
- Installation of an irrigation meter
Residential projects that do not require submittal of a Utility Service Application:
- Renovation / Remodel / Addition
Commercial Projects and Multi-Family Projects (3 or more units)
Listed below are general guidelines for determining when the submittal of a Utility Service Application is required for a commercial project, including multifamily townhomes and condominiums.
Commercial projects that do require submittal of an application for Water and Wastewater service are as follows:
- Construction of a new commercial building(s), including locations where an existing building that previously had water or wastewater service is demolished and a new building is constructed
- Expansion, additions, or interior remodels to existing buildings currently served by a 1-inch water meter or smaller that includes the installation of additional water fixtures
- Expansion, additions, or interior remodels to existing buildings involving a change in use located in a Contribution in Aid of Construction (CIAC) area
- Any project that requires a new or an additional connection or a change to the existing connection to the City’s water or wastewater system
- Expansion, additions, or interior remodels to existing buildings located on a site where there has not been an active water and/or wastewater account within the last five (5) years (regardless of the amount of plumbing involved)
- Interior finish/buildout of a new vacant unit currently connected to the City’s water and/or wastewater system
- Projects that include the construction of public utility infrastructure for either existing or future projects
- Replacement or installation of new pumps in an existing pumping station (only wastewater application required)
- Addition of fire protection system, increase in fire flow demand, or modifications to the existing fire backflow prevention devices.
- Requesting a relocation of the existing meter
- Replacement of water booster pump with a greater capacity
- A new fire protection system is proposed OR an existing fire protection system is proposed to be modified; a fire protection system is considered to be modified when an additional area is protected or a greater density of sprinkler heads is to be provided. Maintenance or rehabilitation activities, such as replacing or relocating fire sprinkler heads, is not considered a modification for the purposes of determining if a Utility Service Application is required.
- Installation of an irrigation meter.
- Installation of a public fire hydrant assembly
- Abandonment / removal of public utility infrastructure
Commercial Projects that do not require submittal of a Utility Service Application:
- Expansion, additions, or interior remodels to existing buildings with no plumbing work
- Interior remodels that involve plumbing, but do not include additional water fixtures. These projects include:
- Replacement of existing plumbing fixtures in-kind
- Relocation of existing fixtures
- Relocation or replacement of plumbing pipes
- Removal of existing plumbing fixtures
- No net increase in plumbing fixtures
- Expansion, additions, or interior remodels to existing buildings that involve plumbing and additional fixtures, but the site is currently served by a 1-½-inch water meter or larger unless the scope of the project is substantial and outside of a typical remodel project
- Projects located on a site served by a private water system (well) and a septic tank; the Developer must provide proof from the County Health Department that the project does not require connections to the City’s water or wastewater system.
1.2.2 Utility Service Application Submittal Guidelines
A Utility Service Application is a joint utility application utilized by both the Water and Wastewater Departments. Utility Service Applications may be submitted online through the City’s permitting website at ACA.TampaGov.Net.
A portable hydrant meter may not be requested through the submittal of a Utility Service Application. Please see Section 1.2.3 for portable hydrant meter guidelines.
Single Family Residential
A Single Family Residential project involves the construction of one (1) residential building.
A Single Family Residential application submittal package must include the following:
- Application Fee
- Utility Plan (if applicable)
- Letter of Authorization for Separate Agent (if applicable)
- Water Customer Data Sheet (if requesting a meter larger than ¾”)
- Fire Flow Data Sheet (if applicable)
- Irrigation Demand Worksheet (if requesting an irrigation meter)
- Water Booster Pump Details (if a booster pump will be installed)
- ERU Calculation Spreadsheet (if within a Contribution in Aid of Construction area)
- Water Meter Placement Diagram
For residential meter installs on undeveloped properties (i.e. where there is nothing on the lot that would be a good reference point for the installation contractor, such as a driveway) please ensure the meter placement diagrams include dimensions from a property corner or some other recognizable landmark to the desired meter location.
Fire Hydrant Assembly
If an existing property owner desires to have a public fire hydrant assembly (FHA) adjacent to their parcel and the public FHA spacing requirements do not currently meet the standards established herein, then an application may be submitted for the installation of a public fire hydrant. The applicant will be responsible for all cost associated with the installation.
A fire hydrant assembly application submittal package must include the following:
- Application Fee
- Water Meter Placement Diagram OR Utility Site Plan
- Letter of Authorization for Separate Agent (if applicable)
The design and installation of the FHA will be performed by either the City or by the Applicant. If the City is to perform the work, the Water Meter Placement Diagram / Utility Site Plan will be used to indicate the desired location of the proposed FHA; however, the City will determine the final location of the FHA.
Interior Build-out
It is common for larger commercial projects involving a collection of smaller commercial spaces, or units, to be constructed as an Infrastructure Only project with the final determination of the use of each unit to be determined at a later time. The use is typically determined by the tenant to occupy the unit. In such cases, only the shell of the buildings or units will be constructed and a subsequent Utility Service Application is required once a tenant is selected.
An application will be required for every Interior Build-out project. If a water meter(s) is installed and fees charged as part of the original Infrastructure Only project, the meter size and fees are an assumption based on the anticipated final use of the unit. The Interior Build-out is application is to confirm the proper fees were collected by the Water Department and as a trigger to set up an account for the new tenant.
An Interior Build-out application submittal package must include the following:
- Application Fee
- Utility Plan
- Letter of Authorization for Separate Agent (if applicable)
- Water Customer Data Sheet
- Fire Flow Data Sheet
- ERU Calculation Spreadsheet (if within a special Contribution in Aid of Construction area)
- Water Meter Placement Diagram (if a new meter is proposed)
Interior Remodel / Minimal Plumbing / No Plumbing
Remodeling projects for existing buildings and projects involving the construction of an addition to an existing building that generates minimal or no change in demand on the Water Department’s distribution system are classified as Interior Remodel / Minimal Plumbing / No Plumbing.
An Interior Remodel / Minimal Plumbing / No Plumbing application submittal package must include the following:
- Application Fee
- Utility Plan
- Letter of Authorization for Separate Agent (if applicable)
- Water Customer Data Sheet
- Fire Flow Data Sheet

1.2.3 Portable Hydrant Meter Application Submittal Guidelines
At the request of the Developer, the City may install a meter on a fire hydrant assembly. Water service from hydrants is provided to meet needs of a temporary nature, such as construction or other similar needs, as approved by the Director or their designee.
The initial term of service is six months with three-month extensions. Extensions must be requested in writing before the expiration of the current term. Only Water Department personnel are to install, move, or remove temporary meters.
Payment of the appropriate deposit and installation fee in accordance with the latest applicable City Council fee resolution must be made prior to installation or relocation of a portable meter.
The first month’s bill will include any consumption charges and rental fees. If the applicant wishes to have the meter relocated, an email must be sent to PortableHydrantMeter@tampagov.net and a relocation fee will be invoiced on the next month’s bill. The meter may be removed either at the request of the applicant or by the City without notice due to non-compliance by the applicant. The portable meter removal process is as follows:
- Via Request from the Applicant – Mail the request to PortableHydrantMeter@tampagov.net and the meter will be removed. A deposit refund will occur when:
- A written removal request is on file and the meter has been removed, and
- A written deposit refund request has been received by the Water Department, and
- Payment in full of all fees has been received.
- Due to Applicant Non-Compliance – The portable hydrant meter will be removed without notice when:
- The meter is used, for any reason, as a permanent meter to avoid payment of fees for permanent service, or
- No water consumption is registered for a period of three (3) consecutive months, or
- The account is not paid within 30 days of billing date appearing on the statement. The deposit on the account will be applied against the balance due.
Cost of damage to, or loss of, Department equipment will be applied against the deposit and the Department will pursue restitution by the customer of any loss not covered by the deposit.
A Portable Hydrant Meter application package must include the following:
- The completed Portable Hydrant Meter Application
- Initial fee payment as follows:
- A check for the deposit and installation fee, or
- Contact Development Services about other payment methods
- Written permission from the parcel owner to install the portable hydrant meter on an on-site, privately owned, fire hydrant assembly (If applicable)
- A site plan of the project area, if the project encompasses more than a single parcel
1.2.4 Utility Service Application Review
The Department’s Development Services Section staff will review the application. Information that will affect the decision on commitment for water service must be submitted in writing. If the application is incomplete, the applicant will be notified what additional information is needed and provided a date by which information must be received by the Department.
1.2.5 Water Service Commitment Generation and Issuance
If providing water service is physically feasible, financially feasible, and consistent with all Department requirements, a commitment of water service with conditions as appropriate will be issued to the applicant.
1.2.5.1 City vs Developer-Installed Projects
For any project requiring a Utility Service Application, the design, permitting, and construction responsibility for required public water facilities will be determined by the Water Department Director or their designee. Said responsibility will be outlined in the commitment for water service.
If it is determined that the City will perform the design, permitting, and construction of the new public water facilities, the City will be responsible for all associated requirements to provide water service. The responsible party of the project (Applicant, Developer, or Property Owner) will be responsible for all charges and fees associated with the design, permitting, and construction of public water facilities.
If it is determined that the responsible party of the project will perform the design, permitting, and construction of the new public water facilities, then the responsible party of the project will be responsible for all associated requirements to provide water service. It is the responsible party’s responsibility to meet the conditions expressed in the commitment for water service and satisfy design, permitting, and construction requirements as set forth by the Water Department and any other applicable regulatory agencies.
1.2.5.2 Siting
If the parcel for which water service is requested does not abut a dedicated public right-of-way, the water service will be located within public right-of-way. The owner shall provide the Department with evidence of a recorded easement(s) creating a corridor to extend privately owned and maintained piping from said parcel to dedicated public right-of-way. Said easement(s) shall be recorded prior to water service commitment issuance.
Other siting requirements, including easement requirements, will be summarized in the commitment for water service.
1.2.5.2.1 Special Areas
Per City Code, no new private or irrigation wells shall be drilled in an ASR area of influence, the area bounded by W Waters Ave to the North, W Martin Luther King, Jr. Blvd to the South, N Florida Ave to the East, and N Himes Ave to the West.
No use of groundwater or new wells are allowed in the area bounded by E Washington St to the North, Channelside Dr to the East, E Whiting St to the South and N 12th St to the West. RE: Brownsfields Site ID #BF290401001, FDEP Com_233834.
1.2.5.3 Sizing
The commitment for water service will designate required water main, meter, and fireline sizing.
1.2.5.4 Fees
The commitment for water service will identify and serve as the invoice for applicable Water Department fees.
1.2.5.4.1 Application and Review Fees
Application fees do not apply to City of Tampa departments. Application fees apply to all other government entities unless mentioned otherwise herein or are exempted from said fees via law, rule, etc. Customers will be charged an additional application fee if a commitment for water service has been issued and the customer requires a commitment for water service revision, unless the need for the revision was caused by the Water Department.
1.2.5.4.2 Connection Fees
Connection fees are intended to recover the City’s investment in water distribution (excludes transmission, pumping, storage, treatment, water resources) infrastructure less the cost of service connections. Connection fees are established by a City Council Resolution. Common connection fee issues include the following:
- Connection fees apply to all new connections unless specifically stated otherwise herein.
- Connection fees do not apply to the Hillsborough County School Boards; however, they do apply to the Florida Board of Regents.
- Connection fee financing is available for owner-occupied single-family residences within the City and owner-occupied single-family residences existing in unincorporated Hillsborough County prior to October 1, 1997. See City Code for additional details.
- Connection fees are assessed on redundant domestic and / or fire main connections if the customer chooses, or is required, to install redundant service connections.
- Connection fee credits are based on the largest, current connection fee associated with the largest historically installed meter size. Credit may be extended if an existing meter would be inadequate for proposed additions and if a connection fee was originally paid.
- Connection fees are not required for irrigation meters, provided the irrigation meter is not larger than the domestic meter at that location. Irrigation meters at locations without a domestic meter are charged connection fees.
- All new domestic meters serving existing and proposed duplexes will be charged connection fees.
- Strip mall units that are currently master metered and desire to have an individual meter installed will be charged full connection fees regardless of existing master meter size or unused existing meter capacity.
1.2.5.4.3 Service Installation Fees
Customers needing a new or modified service shall be invoiced installation fees as allowed by City Code and / or City Resolutions.
1.2.5.4.4 Abandoned Service Renewals
Abandoned Service Renewals apply to instances where a customer requests water service for a premises, but the previous service has not been active for the below specified time period. In such instances, it is the policy of the Department that the service will be installed after payment, per
City Code, of application and service installation fees. The amount paid will be as set forth in the current fee resolution adopted by City Council.
If a property that has historically been served with City water service has not had an active account for five (5) years, the property will be considered an abandoned water service property, regardless of service size or service type (domestic, irrigation, reclaimed, fire).
If a customer requests water service for an abandoned water service property, the fees associated with re-establishing water service shall include the following:
- If the existing service is consistent with current engineering standards, can be located without excavation, is adequately sized, and is adequately sited for the customer's needs, then the City will install a meter of the same size as pre-existing on the existing service line upon the customer being invoiced the abandoned service renewal fee.
- If the circumstances vary from the above, the fees are as follows:
- If a new service installation would be cost prohibitive (e.g. a long-side set on a 4 lane road, along FDOT right-of-way, or along non-City right-of-way that involves a pavement cut, or similar):
- If the service is in acceptable condition and the service can be located, is adequately sized & sited for the customer's needs, is in acceptable visual condition, and passes a City-performed pressure & flow test, the City will install a meter of the same pre-existing size on the existing service upon the customer’s account being invoiced an abandoned service renewal fee. The pressure and flow tests are defined below.
- If a new service installation would be cost prohibitive (e.g. a long-side set on a 4 lane road, along FDOT right-of-way, or along non-City right-of-way that involves a pavement cut, or similar):

- If the existing service does not meet the aforementioned criteria, a new service will be installed by the City upon the customer paying all applicable water service installation charges. A meter may be temporarily installed on the existing service line, at the Water Department’s discretion, subsequent to the customer paying the water meter installation charges and being invoiced the abandoned service renewal fee, solely for the purposes of reducing the time necessary for the customer to re-establish water service.
All other locations:
- A new service will be installed by the City upon the customer paying all applicable installation charges. A meter may be temporarily installed on an existing service line, at the Water Department’s discretion, subsequent to the customer paying the water meter installation charges and an abandoned service renewal fee, solely for the purposes of reducing the time necessary for the customer to re-establish water service.
1.2.5.4.5 Deposits
Deposits are required per City Code and City Resolution. Deposits do not apply to governmental-type agencies (state, authority, etc.) and fire lines.
1.2.5.4.6 Meter Drop-In Fees
Meter Drop-In Fees apply to Developer-installed water services. If the City installs a meter into a Developer-installed water service and the meter subsequently goes missing prior to the certificate of occupancy, the customer will be charged an additional meter drop-in fee for the City to install a replacement meter.
1.2.5.4.7 Large Meter Furnishing Fees
Customers will be charged the City’s cost of ≥3” meters plus a 25% handling fee.
1.2.5.4.8 City Installation Cost Estimates
When a customer’s water service needs involve any of the below listed circumstances and the construction will be performed by the Water Department, a cost estimate will be generated by the Water Department to satisfy the customer’s water service needs.
- Main extensions, relocations, or upgrades
- Meter ≥3"
- Fire service
- Public Fire hydrant
- Long-side meter installations along four-lane roads
- Work in FDOT or Hillsborough County right-of-way involving a pavement, curb, or sidewalk cut
- Work requiring excavation of pipe having >5' cover based on available as-builts
- Meter service line length greater than 80’
- Meter service line nominal diameter greater than 2”
The customer will then be assessed installation fees consistent with the Water Department’s cost estimate. The Water Department will strive to minimize the customer’s cost while maintaining the Water Department’s technical standards. Customers will not be charged additionally if the cost estimate is less than actual costs. Similarly, partial refunds will not be issued if the cost estimate is higher than actual costs. Cost estimates will include overhead and contingency consistent with the current Department Standard. Cost estimates will include restoration as required by the applicable right-of-way owner.
Water Department installation cost will be determined case-by-case. New growth and development will pay for water main improvements, unless otherwise approved by the Water Department Director. For existing buildings, the main extension should front ten (10) feet of a property. For proposed buildings, the water main should front the entire length of the proposed building’s property, unless there is no expected need to ever extend the water main. For a corner property, the main extension is required only on one side of the property. If a main extension is needed for the customer, a cost estimate will be prepared for installing the water main needed for the customer. The customer will be charged the following:
- Connection fee(s) and
- An aid in construction fee equivalent to the cost estimate value less the connection fee value.
1.2.5.4.9 Aid In Construction Fees
See the City of Tampa Water Department’s Contribution in Aid of Construction (CIAC) policies and the following clarifications:
- The applicant is solely responsible for providing sufficient documentation to provide the Water Department reasonable assurance the claimed historic property usage is accurate. If documentation regarding historic property usage is unavailable, then 15 gpd / 100 square foot of building space may be extended as CIAC credit when there are sufficient records available to show historic building existence and dimensions.
- An irrigation meter installation for a property also served by a domestic meter does not have additional irrigation CIAC fees due because it is assumed irrigation demand is included in the property usage based CIAC fee. If a property is only served by an irrigation meter, CIAC fees apply to the irrigation meter on an equivalent residential unit basis (1 ERU = 300 gpd) based on the customer submitted irrigation demand worksheet.
- Barber & Beauty Shops – if there are 9 total service chairs in the shop as follows:
- 5 chairs for hair cutting / hair styling
- 3 dedicated chairs for hair drying
- 1 dedicated chairs for hair washing
- The Barber/Beauty Shop is considered to have five service chairs.
- Any residential unit having a shared wall with another residential unit are considered multifamily for CIAC fee purposes.
- The daily average water flow factors for a building, structure, or property use are outlined below in order to calculate the equivalent residential unit.

1.2.5.4.10 Capacity Fees
A water capacity fee shall be required for any building, structure, or property receiving water service from the City. The water capacity fee shall be based on the Equivalent Residential Units (ERUs) and location of the building, structure, or property receiving water service and multiplying by the number of ERUs by the water capacity fee for 1 ERU.
The Department shall calculate the net ERUs based on the use of the building, structure, or property and estimated net projected average daily flow. One (1) ERU is equal to 300 gallons per day of average water use for the purpose of calculating the number of ERUs. The daily average water flow factors for a building, structure, or property use are outlined in the table in Section 1.2.5.4.9 of this document.
For a building, structure, or property with previous water service from the City, previous use will be accounted in calculating the net projected daily flow using the flow factors based on previous use. If a property is located within one of the CIAC areas, where CIAC fees are collected for the cost of transmission and storage system components, a reduced water capacity fee that only accounts for the treatment system component shall apply.
In accordance with Section 163.31801, Florida Statutes, the City may provide an exception or waiver for the water capacity fee for the development or construction of housing that is affordable, as defined in Section 420.9071, Florida Statutes. Section 420.9071, Florida Statutes, definition shall be applied to determine if a development is “affordable” to qualify for $0 water capacity fee. It shall be the applicant’s responsibility to provide official documents sufficient to demonstrate that a proposed development qualifies under the Florida Statute definition.
The water capacity fee will be due to the Department prior to the permit issuance. The Department shall withhold approval on the issuance of any site, utility, building, building remodeling, foundation, and/or plumbing permit for a building, structure, or utility appurtenance until the applicable capacity fees are paid.
The water capacity fee, once paid, can’t be transferred or used as a credit or partial payment towards the applicable capacity fee, which may be due and payable for an existing or proposed building, structure, or service connection located on or to be located on a different lot or parcel of land.
The water capacity fees will be reviewed every five (5) years and updated, if determined to be necessary.
1.2.5.4.11 Permit Fees
The City will assess to the customer any 3rd party permit fees to complete the work necessary to serve the applicant. The City does not charge a markup on these fees. Typically, the City only assesses permit fees on certain City-installed projects.
1.2.5.4.12 Inspection Fees
Developer-installed projects will be assessed inspection fees as allowed by the applicable City Council resolution.
1.2.5.4.13 Fire Readiness to Serve Fees
The customer will be assessed an annual fee on all fire services based on the fireline’s nominal diameter.
1.2.5.4.14 Temporary / Construction Service Fees
Water service from hydrants is provided to meet needs of a temporary nature. Payment of the appropriate deposit and installation fee in accordance with the latest applicable City Council resolution must be made prior to installation of the portable meter and delinquency beyond thirty (30) days of the billing date shall be cause for removal of the meter without notice.
1.2.5.4.15 Meter Relocation Fees
Customers requiring their water service to be relocated will be charged fees per the applicable City Council Resolution.
1.2.5.5 Connection Fee Financing
Connection fee financing is available for owner-occupied single-family residences within the City and owner-occupied single-family residences existing in unincorporated Hillsborough County prior to October 1, 1997. See City Code for additional details. A recorded warranty deed is required to verify the name on the utility application matches the property owner. The property appraiser’s website is used to verify the name on the utility application matches the property owner and that the property is homesteaded. The City of Tampa will place a lien on the customer’s property if water connection fees are financed. The 24 month term and 8% interest rate is set by code; however, customers are free to pay off the financed amount at any time within the 24 month term. All other fees such as agreement recording fees, meter installation fees, and application fees must be paid by the customer prior to the meter being installed. The City of Tampa will record a lien release upon receiving final payment.

- Include the City funding source for the upfront fees and the monthly charges.
- Upon submitting a completed USA form, the Water Department will begin to install water service or otherwise complete the scope identified in the water service commitment letter.
1.2.5.10 City-Installed Target Time Frames
Target installation schedules for City-installed projects are as follows:
- At least 3-5 working days for small (≤2”) meter installations necessitated by a private well failure if HCHD/HEP/FDOT permitting or main extensions are not required.
- At least 3 weeks for small (<3”) meter installations or relocations having no HCHD/HEP/FDOT permitting.
- At least 3 months for City-installed small meter (<3”) installations that require HCHD/HEP/FDOT permitting.
- At least 8 months for Fire Hydrant Assembly (FHA) installations, FHA relocations, City-installed main extensions, large meters (≥3”) and /or fire mains.
All City-installed installation schedules commence upon water service commitment fees remittance.
1.2.5.11 Cross Connection Control
This manual incorporates the City of Tampa Water Department Cross Connection Control and Backflow Prevention manual via reference, as occasionally amended or revised. Also, refer to the most recent Rules of the Florida Department of Environmental Protection, Table 62-555.360-2: Categories of Customers for Which Each Community Water System (CWS) Shall Ensure Minimum Backflow Protection Is Provided at or for the Service Connection from the CWS to the Customer.
Townhomes are considered residential for cross connection control purposes in the reclaimed area. The Water Department will own and maintain water meters with integral backflow preventers for individually metered townhomes within the reclaimed area. If townhomes in the reclaimed area are master metered, the customer shall own and maintain the backflow preventer (BFP).
Florida Administrative Code requires a dual check device at a residential property connected to reclaimed water service. In an abundance of caution, the Water Department standard for this situation is a double check device to ensure test ports are available for testing.
If a backflow preventer is City-owned, the testing and maintenance of that preventer is done by the Distribution and Consumer Services Division. If a backflow preventer is privately owned, the testing and maintenance is the customer’s responsibility with compliance monitored by the City’s Field Quality Group.
The backflow prevention device and associated assembly shall be upgraded to current FDEP and Water Department standards at the customer’s expense, if:
- The Water Department is providing fire service to a customer utilizing a backflow prevention device inconsistent with standards set by FDEP rule(s) and
- The customer submits a Utility Service Application and pays the resulting water commitment letter fees.
Ownership (unless in conflict with City Code or the applicable water commitment letter):
Separate fire and domestic supply piping with fire backflow prevention or combined fire and domestic supply piping with fire backflow prevention device other than a reduced pressure backflow prevention device:
- All fire service piping, fittings, and appurtenances shall be owned by the Water Department up to, and including, the first valve on the customer side of the fire backflow prevention assembly. The fire backflow prevention assembly consists of two (2) hand wheel valves, a backflow prevention device, and may also include a leakage/theft detector, as shown in Department Standard Details. In the event there is not an isolation valve within the grassed
area or easement on the customer side of the backflow prevention assembly, the Water Department shall own up to:
- The point of customer connection, as shown on available record drawings, or
- The customer side flange face of the backflow prevention assembly.
Combined fire and domestic supply piping with reduced pressure fire backflow prevention device:
- All service piping, fittings, meter(s), and appurtenances shall be owned by the Water Department up to, and including, the downstream flange face of the meter. The reduced pressure backflow prevention device shall be installed on the customer side of this meter.
If no fire main backflow prevention device is installed, the Water Department shall own up to:
- The point of customer connection, as shown on available record drawings, or
- The right-of-way line.
The Water Department shall not own fire main piping, valves, backflow prevention devices, and appurtenances outside of the Water Department’s grassed area or easement unless otherwise stated in the commitment for water service or other comparable document, as determined by the Water Department.
1.2.6 Design
Developer-installed water main construction plans shall be submitted to the Department’s Development Services Section for review (i.e. “plan review”). Plans will be reviewed for conformance with Water Department technical standards. Once the Developer’s plans are determined to be in conformance with Water Department technical standards, the Engineer of Record (EOR) licensed in Florida shall sign and seal the approved plans and submit them to the City’s reviewing engineer. The Department’s stamp of approval (signifying Development Services Section agreement the plans appear to substantially conform to Water Department standards) will be affixed to those plans, and the plans returned to the EOR for use during construction. The Department requires the Developer’s water main Contractor to construct the public water facilities with construction drawings signed and sealed by the EOR and bearing the Water Department’s stamp of approval.
During plan review, if Developer-installed construction plans are determined to not comply with current Department standards and specifications, items requiring revision will be identified through written comments and / or a completed Water Department Construction Drawings Checklist (see Section 2.1.1.5 for current Department Checklist). The checklist lists common technical specifications that must be addressed in the EOR’s construction plans. To expedite plans approval, the EOR is encouraged to review the proposed plans against this checklist prior to submitting for plan review. The Developer’s EOR shall make all required corrections to the plans and submit revised plans for plan review. This process will be repeated until the Developer’s plans are submitted consistent with all technical standards. Plans must be approved within the active timeframe of the governing commitment for water service. If the commitment for water service expires prior to plan approval, the project will be cancelled and fees refunded. Fee refunds will only be sent to the party who submitted the original payment. The Developer must reapply for a new water commitment when ready to proceed with the project.
After receiving notice that the plans are acceptable for construction, the Developer shall submit the following to the Department:
- To be retained for Water Department use:
- Four (4) complete sets of the Developer’s overall project construction plans that include the approved plans for the construction of the City water facilities. Submitting
- “partial plans” (plan sets including only sheets of the Developer’s overall plan set that address the proposed water construction for the City, including any plans showing drainage or sanitary sewers that are impacted by, or will be impacting, the water facilities’ construction) can be discussed with, and may be approved by, the Reviewing Engineer at time of plan approval.
- An electronic copy of the construction plan AutoCAD file(s) approved by the Development Services Section, in .dwg format, or approved equal. Submittal shall include an “Index of Files” identifying applicable City water construction drawings.
- A copy of the applicable permits (FDEP, FDOT, etc).
To be returned to the Developer, for Developer use:
- The number of Department-stamped, approved construction plan sets required by the Developer for distribution and construction. Department specifications require that the Developer’s water main Contractor construct water facilities from plans approved and stamped by the Department, and that a complete set of plans that have been stamped by the Water Department shall be kept on the construction site at all times.
Final Developer construction plans submitted for Department approval (ready to be stamped as approved for construction) must bear the signature, date and seal of the Florida Registered Professional Engineer (the EOR) in responsible charge of the project design. Signing and sealing may be limited to all sheets related to water line construction, including any master utility site plan, individual plan and profile sheets, and any EOR detail sheets. It is not necessary for the EOR to sign and seal the Water Department’s Standard Details.
Construction approval will remain in effect while there is an active commitment for water service for the project.
1.2.7 Third Party Permitting
It is the permittee’s responsibility to ensure all required permits are obtained per applicable regulations. Some regulations pertaining to water main extensions and water service connections are codified in Florida Administrative Code Chapter 62-555, Hillsborough County Ordinance 00-4 and 03-20 and City of Tampa Ordinances Chapter 26.
1.2.7.1 City-Installed
The City will pursue obtaining all required permits.
1.2.7.2 Developer-Installed
The Developer shall obtain all permits necessary to comply with all regulations. Copies of issued permits must be provided prior to the scheduling of a pre-construction meeting with the City’s assigned inspector.
Any permit requiring Department or City signatures must have Department-approved construction drawings.
Developer construction shall not start until all terms of permit comment periods have been met. The waiting period associated with Florida Department of Environmental Protection (FDEP) “Notification for Use of the General Permit for the Construction of an Extension to a Public Drinking Water Distribution System” application and approval process may exceed 30 days. Additional information about FDEP permitting requirements can be found on the FDEP website, at http://www.dep.state.fl.us.
If a FDEP or HCHD Permit is required, no connection to the City’s water system is allowed until the connection has been approved by the Hillsborough County Health Department. After the Developer-installed water facilities have been constructed and tested, the Developer shall apply to FDEP for release of the newly constructed facilities by submitting the “Certification of Construction Completion” and “Request for a Letter of Clearance to Place Public Drinking Water Facility into Service”. Once the release is obtained and has been provided to the Contract Administration Department, the facility may be connected to the City’s water system without everyday use of water. Until ownership has been transferred to the City of Tampa, valves will be closed and meters locked until all requirements have been met, including a backflow preventer inspection by the Department’s Cross Connection Control Section. Exception is allowed to this “locked meter” requirement if the Developer-installed project is for providing water service to single family residences which do not require backflow prevention devices.
Before submitting the application form to the Department for City sign-off, the Developer should review the City data to ensure that it is the most current as of the date of the submittal.
1.2.8 Construction
Approved construction plans will be forwarded to the City’s Contract Administration Department to facilitate the required coordination among the Developer, Contractor, Inspector, and Construction Engineer. The Developer and/or their representatives shall use the project number (e.g. UTL-yy-zzzzzz) to reference the project in all communication.
A pre-construction meeting will not be permitted until five (5) working days after any applicable required permits have been issued from the Hillsborough County Health Department and / or the Florida Department of Transportation have been received by the Water Department. During this contact, the Developer’s representative shall provide an e-mail address to which Department-required forms can be sent for Developer use, including several forms which must be completed by the Contractor prior to the Pre-Construction meeting.
1.2.8.1 Material Submittals and Pre-Construction Meeting
The Developer’s EOR shall submit five (5) completed and signed copies of the current Water Department “Approved Materials List” submittal form to the Water Department Contract Administration Department office.
The Approved Materials List identifies various manufacturers and products that have been previously approved by the Water Department. If Developer-proposed pipes, fittings, valves, hydrants, and other pipe appurtenances are listed therein, the Approved Materials List submittal form will be the only submittal required by the Contract Administration Department for review and acceptance of the Contractor-provided materials. The current Approved Materials List submittal form is available from the Contract Administration Department office and will be e-mailed to the address provided by the Contractor when arrangements are made for the pre-construction meeting.
Contractors proposing to install products not included in the Approved Materials List must submit material certifications and shop-drawings for those non-listed materials to the Department for review and approval to:
Contract Administration Department3808 E. 26th Avenue
Tampa, FL 33605
ATTN: Chief Construction Engineer
Developer-proposed materials requiring submittal for approval include, but are not necessarily limited to, the following:
- Pipe
- Fittings
- Valves
- Hydrants
- Service lines
- Restraint devices
Other materials may require submittal, as determined by the Chief Construction Engineer.
Five (5) originals of a material submittal are required and each must bear a signed, sealed, and dated (Florida P.E.) statement attesting to conformance with the Department’s specifications. The submittal forms must be hand-delivered or mailed to the Contract Administration Department. Faxed submittals will not be accepted.
After approval of the Developer’s proposed water main construction materials, the Developer’s representative shall schedule the mandatory pre-construction meeting with the Contract Administration Department. All parties responsible for the Developer-installed construction, and the final transfer of those facilities to the City after construction, shall attend the meeting, including but not limited to the construction P.E., the Contractor, and the Developer or their representative.
Developer-installed water main construction may not begin until materials are approved by the Contract Administration Department, the Pre-Construction meeting has been held, the Contractor-provided materials have been inspected by CAD, and the Pre-Valve and Shutdown Request forms have been submitted. These forms shall be available to the Contractor from the assigned City inspector.
Under no circumstances shall contractors tap or connect to a City of Tampa water main without written authorization from the Department’s Construction Engineer.
Any Developer-installed water facilities constructed prior to materials approval, materials inspection, and the pre-construction meeting are subject to Developer removal and replacement at the discretion and direction of the Water Department, at no cost to the City.
1.2.8.2 Hydrostatic and Bacteriological Tests
The Developer shall be responsible for performing City Inspector witnessed hydrostatic and bacteriological tests, per section 2.2.7.2 of this document, for all Developer-installed projects.
1.2.8.3 Clearance Application
The Developer is responsible for submitting DEP/DOH clearance applications, as applicable, for Developer-installed projects.
1.2.9 Developer Agreements
All Developer-installed projects require the execution of TWD’s standard Developer Agreement prior to CO holds being released. There are seven (7) different forms for this agreement depending on the type of entity involved (corporate, individual, two individuals, joint venture, LLC, partnership, and special entity). The Customer is required to submit three (3) original, signed agreements for City processing. The submittal shall include Exhibit I “Engineer of Record Certification of Materials” and Exhibit II “Engineer of Record Certification of Construction Costs.” Customers are encouraged to submit these documents for City execution as soon as possible to prevent CO issuance delays.
1.2.10 Project Closeout
1.2.10.1 Record Drawings
Purpose: The purpose of this section is to establish as-built data collection standards for the water pipe networks. These standards shall be met for all Developer-installed water main extensions, relocations or replacement.
Definitions:
- As-Built – Revised set of drawings submitted upon project completion reflecting all changes made in the specifications and drawings during the construction process and showing the exact dimensions, geometry, and location of all elements of the work completed.
- HDD – Horizontal Directional Drilling (HDD) is a minimal impact, trenchless method of installing underground pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground bore path by using a surface-launched drilling rig.
- Coordinates – x, y, and z coordinates.
- Limits of Pipe – The beginning and ending points of a pipe where it may or may not connect to the TWD water system.
During construction, installation, and testing, records shall be created and maintained of all work performed.
The Contractor shall provide TWD with:
- One (1) unlocked AutoCAD (Civil 3D preferred) drawing electronic file (.dwg format) with an updated and accurate pipe network(s) that depicts final field conditions, and
- One (1) signed and one (1) unsigned electronic copy in Portable Document Format (PDF) of the as-built drawing.
The as-built shall be signed and sealed by a Florida registered Surveyor and a Florida registered Professional Engineer (digitally signed and sealed is acceptable). The paper size shall be “11x17.”
AutoCAD drawing requirements:
- The as-built shall be geo-referenced to the Florida State Plane Coordinate System, Traverse Mercator, West Zone of 1983 in feet (NAD 83-90 FT). All vertical elevations shall be referenced to the North American Vertical Datum of 1988 (NAVD88).
- All x, y, and z coordinates will be shown to 0.xx’ accuracy on the As-Builts.
The Consultant / Contractor / Developer is responsible for, and shall verify, the AutoCAD version to be utilized with the Water Department’s Drafting Supervisor prior to starting the record drawings’ survey.
The as-built shall indicate pipe size and material. It also shall include the x, y, and z coordinates (Easting(x), Northing(y), Elevation(z)) at:
- All water fittings
- Water meter services (corporation stop, center of meter box top, center of housekeeping pad if applicable)
- The operating nut of all valves and hydrants
- Top of pipe for one side, where the pipe goes into each valve bell
- Top center of pipe at no greater than every fifty (50) feet along all water pipelines (transmission and distribution) including the beginning and ending connection points to the TWD water system
- Top center of the casing ends for pipes installed via Jack and Bore construction method
- Top center of the pipe at all excavated locations for pipes installed via pipe bursting
- Top center of the pipe at the limits and all excavated locations of the abandoned pipe
- Method of abandonment
- The pipe locations as contained in the bore log for pipes installed via HDD and the bore log
1.2.10.2 Closeout Checklist
Upon completion of the Developer-installed water main construction, the installations must be field accepted and finalized by the assigned Contract Administration Department inspector. Any meters served from Developer-installed water mains will not be released to the Developer until the following have been provided complete to, and accepted by, the Contract Administration Department:
- Two (2) sets of as-built construction plans, per Section 1.2.9.1 Record Drawings
- One (1) “Construction Costs” form completed, signed, and sealed by the Engineer of Record
- Two (2) copies of the bacteriological (Bac T) samples report, one for City records and one for transmittal with the Hillsborough County Health Department clearance forms. Bacteriological samples reported cannot be over 60 days old and must have been processed with appropriate chain-of-custody documentation by a City of Tampa approved lab (samples hand-carried to the lab by persons other than laboratory personnel will not be accepted). The name and telephone numbers of the lab the Contractor proposes to use for bacteriological sampling and testing shall be provided to the Water Department inspector at the pre-construction meeting.
- Completed DEP Clearance Application Form, ready for required sign-off by the Contract Administration Department’s Chief Construction Engineer. After said sign-off on the form, the Developer shall forward the application form and documentation to the Health Department for DEP project close-out.
- Three (3) sets of completed City of Tampa Developer Agreements, all bearing original signatures
The referenced forms are available from the Contract Administration Department. Because it is a violation of State Statute for the City of Tampa to provide water service to customers from new water mains without final clearance from the Department of Environmental Protection, no meters will be provided to customers until the required documents are provided and accepted.
A sample Health Department clearance form will be provided by the Contract Administration Department at the Pre-Construction Meeting containing specific City of Tampa information required for the Developer to complete the form. The sample form is also available electronically from the Contract Administration Department.
Sign-off by the Water Department is required on Developer Health Department clearance forms for Developer-installed water facilities. The Department’s Chief Construction Engineer will not sign-off on the clearance form until all other required paperwork has been accepted and approved by the Contract Administration Department. Developers shall fax or e-mail the DEP clearance to the Contract Administration Department.
1.3 Plat and / or Master Planned Developments
State and local law governs how property is divided. Dividing property is accomplished via the platting process. State law dictates that if a property is divided into three or more parcels, it must be done via the platting process. Platting is an administrative process defined by State Law and City Code. The platting process can’t modify a City technical standard or City Code. Final plats must be approved by City Council. The primary goal of the platting process is to ensure public services are available to each created parcel.
Final plats cannot be approved without utilities being readily available or a bond is posted for 125% of the estimated cost to construct the utilities. The respective utility department determines if this bond value is adequate. Ninety (90) percent of the bond value is released when the Water Department Developer Agreement is executed. This transfers infrastructure ownership and starts a thirteen (13) month warranty period. The remaining 10% of the bond value is released after the thirteen (13) month warranty period has elapsed.
There are two types of legal descriptions:
- Platted – reads like “Lot 1 of ‘ABC’ Subdivision”
- Metes and Bounds (has never been platted) – reads like “From the P.O.B., N13 degrees W 100 feet, etc.”
Approved preliminary plats are not required to be approved by City Council; however, they are binding for zoning and permitting purposes. The City only requires preliminary plat approval if a new roadway is involved.
1.3.1 Preliminary Plat Requirements
Water Department requirements for preliminary plat approval include the following:
- A complete utility application has been submitted.
- The right-of-way is sufficient for installation of water systems.
- The easement locations, dimensions, and dedication language are acceptable.
- The right-of-way is delineated as public or private.
1.3.2 Final Plat Requirements
Water Department requirements for final plat approval include the following:
- A water service commitment has been issued.
- Construction plans are approved.
- Easements are delineated and dedication language is sufficient.
- The easement is consistent with the approved construction plans.
- Certified cost estimate or bid received and approved (to determine bond value).
- The performance bond required for improvements is completed prior to City Council review of plat.
- The warranty bond required for public improvements is not completed prior to City Council review of plat.
- Infrastructure construction is complete or bond is posted and infrastructure plans are approved.
Easements for water utility needs can be dedicated via the platting process.
The Water Department requires one application, one commitment letter, and one work order number per project phase. Provided the entire bond value remains effective until all water-related work for all phases included in the final plat are complete, the Water Department has no objection to a final plat including more than one project phase.
1.3.3 Community Master Plan Requirements
1.3.3.1 Components
Customers are required to submit the following for master planned developments:
- A separate utility application for each project phase
- A project narrative describing the entire project and identifying anticipated project phasing
- Hydraulic model file submittal and report
- Phasing plan and anticipated schedule
- Map indicating phases and boundaries
1.3.3.2 Phasing
All phases must function independently if they are to be constructed out of order (i.e. Phase 1 must independently meet Water Department standards if Phase 2 is to be constructed afterwards). Each phase must be applied for independently if they are to be constructed at different times.
1.3.3.3 Hydraulic Modeling
The City utilizes hydraulic modeling software to verify all Community Master Plan water main sizing is consistent with Water Department technical standards. Approval of sizing and layout is at the Water Department’s discretion. Upon the City receiving average day, maximum day, and peak hour flow demands from the Developer, the City will provide the feed pressure to be assumed at each development connection point. The Customer shall submit the hydraulic model files in EPANET .inp format and a report indicating modeled results including the following:
- Minimum 40 psi in distribution mains (non-fire flow conditions)
- Minimum 50 psi in transmission mains (non-fire flow conditions)
- >25 psig residual pressure at 1,000 gpm fire flow (residential)
- >25 psig residual pressure at 3,500 gpm fire flow (commercial and industrial)
- Pipe list indicating diameter, length, C-Factor, and velocity (peak hour and max day + fire flow condition)
C-Factors shall be assumed as follows:
| Pipe Material | C-Factor |
|---|---|
| Ductile Iron | 140 |
- Node list indicating elevation, demand, residual pressure at 1,000 gpm fire flow during maximum day demands (residential), residual pressure at 3,500 gpm fire flow during maximum day demands (commercial and industrial), average day pressure, maximum day pressure, peak hour pressure, and water age
1.4 Right-of-Way Vacates, Right-of-Way Encroachments, and Easement Releases
The Water Department will approve, at its sole discretion, right-of-way vacates, right-of-way encroachments, and easement releases provided said petitions will not compromise the Water Department’s ability to economically provide water service to its customers. During the Water Department’s review, if it is determined that work on the public water system is required to approve a petition, the following Water Department process is utilized prior to approval:
- Customer submits an application for utility service
- Customer pays the resulting commitment fees (if applicable)
- The Developer’s engineer submits signed engineered plans for Water Department Engineering Section’s approval (if applicable)
- The Developer’s Contractor performs the work outlined in the commitment, under observation of a City inspector (if applicable)
- The Developer’s engineer submits as-built plans
- City of Tampa accepts the work
1.5 Demolition Permits
If demolishing any structure on their property, the property owner shall complete a Demolition Permit application through the City’s online application service.
1.6 Rezoning
The Water Department will perform a cursory review of proposed zoning changes and may provide comments pertaining to anticipated Water Department requirements.
1.7 Comprehensive Plan Amendments
The Water Department will perform a cursory review of proposed comprehensive plan amendments and may provide comments pertaining to anticipated Water Department requirements.
1.8 Food Truck Approvals
Upon a customer’s request, the Water Department’s Development Services Section will review “Interagency Coordination of Regulated Establishments – DOH/DACS/DBPR/DCF/AHCA/APD Evaluation of Onsite Sewage (Septic) and Water Supply Capacity” forms. The Water Department will provide its approval on said form if the applicant is a Tampa Water Department customer with adequate water service.
1.9 Requesting As-Builts
Requests for atlas or as-built information may be emailed directly to watermapsandasbuilts@tampagov.net.
1.10 Requesting Fire Hydrant Flow Tests
Those requesting publicly-owned fire hydrant flow test information can do so by emailing the Water Department Planning Section at watercommitment@tampagov.net. Please provide the following information within the email:
- Requester’s name
- Company
- Phone
- Fax
- Location of fire hydrant(s)
If existing hydrant flow test information is not adequate, often due to the test date, a new test will be ordered. Static pressure, residual pressure, and measured flow will be provided to the Customer. Any additional assumptions or calculations will be the responsibility of the requester.
1.11 Building Permit Holds
Whenever one of the following building permit record types is submitted, three Water Department Holds are automatically applied to the building permit:
- Residential New Construction & Additions
- Commercial New Construction & Additions
- Commercial Building Alteration
These holds, and what releases them, are as follows:
- Utility Application required
- Released when the Water Department or Wastewater Department accepts the Utility Application
- Water Commitment required
- Released when the Water Department determines no further action is required on its part or when the Customer pays all water commitment fees
- Water Certificate of Occupancy Hold
- Released when the Water Department confirms all construction work and associated submittals are complete (including easement acquisition documents) and all water commitment fees have been paid
1.12 Easement Acquisition
If the Water Department determines that public water facilities must be located on private property, an easement may be required to be dedicated to the City as determined by the Water Department. The size and location of the facilities will be determined at the time of application for utility service. The public facilities must be centered within the easement. The installation of permanent structures, pavement, impervious surface material, or landscaping will not be permitted within, on, over, or under the referenced easement without prior review and approval of the Water Department. In the event the public facilities located within the referenced easement need to be accessed and / or excavated, the City shall only be responsible for returning the excavated areas to finish grade and restoring any pavement that is disturbed to the quality of pavement that meets the minimum standard for public streets in the City of Tampa.
The following information and items must be submitted to the Water Department in order for the City to prepare the easement dedication:
- A title commitment covering the entire parent tract of the project/development which shows the ownership, legal description, and all encumbrances affecting the property, including copies of all easements of record. The title commitment must be submitted to the Department within 30 days of completion. An Ownership and Encumbrances Report shall not be accepted. For questions regarding City standards for title commitments, please contact the City’s Real Estate Division.
- A Grant of Water Easement deed, consistent with the City’s standards, must be signed and attested to by the property ownership officers, and must convey the easement interest to the “CITY OF TAMPA”. Please leave the date blank on the first page. The portions of the deed to be filled out on the third page are: Witnesses (Two (2) required), Name (as specifically stated in the Title Commitment and/or the Title Policy) and Notary. The easement must be accompanied by any mortgage subordinations, releases, or other legal instruments needed to convey the easement to the City free and clear of all encumbrances. The City of Tampa will record this document. For questions regarding City standards for Grant of Water Easement deeds, please contact the City’s Real Estate Division.
- Three (3) copies of the easement boundary sketches on 8-½” X 11” sheets and an electronic AutoCAD file with the easement boundary sketch. The boundary sketch must include a sketch of the parent tract and easement, along with legal descriptions of both, and must be sealed by a registered Land Surveyor. The proposed easement must be labeled as “Water Easement” and not “Utility Easement”. For questions regarding City standards for boundary sketches, please contact the City’s Right of Way and Mapping Section.
- A Joinder and Consent, consistent with the City’s standards, signed by the Mortgage holder if a lien is outstanding against the property.
If the Grant of Water Easement deed is altered in any way, the submittals will not be accepted, and the proper documents must be resubmitted. A certificate of occupancy hold will be placed on any project requiring an easement to be dedicated to the City of Tampa and will not be released until all information required for the dedication of the easement is received and approved for accuracy.

2.2 Design Standards
2.2.1 General
This section of the manual highlights many of the design standards utilized and required by the Department. This section is not intended to be all-encompassing of Department design standards, but rather to serve as a guide to aid the Developer in the production of water construction plans that are acceptable to the Department. The Developer may be required to comply with additional design standards not listed herein.
2.2.2 Pipe
Department approval will be required for water main sizing. Water mains shall be designed such that the hydraulic requirements are satisfied. The approval will be based on hydraulic calculations submitted by the Developer.
2.2.2.1 Sizing Assumptions
- Permissible source water pressure assumptions for fire flow analysis:
- 40 psi for 12-inch and smaller diameter pipe
- 50 psi for 16-inch and larger diameter pipe
- Use of lower source pressure may be required depending on the project location. Contact the Development Services Section reviewing engineer for guidance.
- Average Day Demands:
- Residential
- Single Family – 300 gallons per day
- Multi-Family – 250 gallons per day
- Residential
- Non- Residential
- Equivalent Residential Unit flow factors in Section 1.2.5.4.9, or
- As justified by the Engineer of Record and approved by the Water Department’s Development Services Section.

| Commercial / Industrial / Downtown | 3,500 gpm for 3 hours and any required onsite fire flow demand as required by NFPA |
Note: The maximum allowable laying length for dead-end water mains feeding fire hydrants shall be:
- 6-inch mains = 500 feet
- 8-inch mains = 2,000 feet
Water distribution and transmission mains shall be sized to provide public fire flow (at the nearest public hydrant), private fire flow (via fire main service), peak domestic demand, and peak irrigation demand concurrently.
Commercial and industrial projects unable to meet the fire flow requirement as outlined above due to physical constraints will be reviewed for variance with the Fire Marshall’s office for approval.
2.2.2.3 Water Quality
A water distribution main installed into a cul-de-sac shall have the following configuration wherever there is adequate space outside the pavement:
A blow-off or fire hydrant (as applicable) shall be installed at the end of the water main. The water main may be reduced to 4-inch at the end of a residential cul-de-sac, provided:
- Installation of fire hydrants is enough to provide fire protection as specified in this document.
- All meters shall be tapped off the 4” main.
Dead-end water mains in other than cul-de-sac situations will not be allowed, unless approved by the Department. A request for dead-end water mains in other than cul-de-sac situations will be evaluated for approval by the Department on a case-by-case basis. Dead-end water mains allowed for other than cul-de-sacs must include installation of a blow-off valve assembly or fire hydrant assembly (as applicable) for flushing the main, in accordance with Department Standard Details.
2.2.2.4 Clearances and Separations
All water mains shall be installed no closer than five (5) feet from right-of-way lines unless otherwise approved by the Department.
Crepe myrtles, palm trees, and other trees with minimal root systems as approved by the Department may be installed within ten (10) feet of a water main and water services. Horizontal water main and service piping clearance to all other types of trees shall be ten (10) feet or greater.
Provisions of Florida Administrative Code and these Specifications shall govern the design criteria when water mains are installed parallel or perpendicular to sanitary sewers, storm sewers, reclaimed water mains, or gas lines. In the event of differing specifications for a given installation, the most stringent specification shall apply.
Wall-to-wall pipe separation shall, at a minimum, be 12-inch vertical and 36-inch horizontal between water mains and all existing or proposed utilities, except sanitary sewers, metal gas lines, and road underdrains, where the minimum wall-to-wall pipe separations shall be as follows:
| Utility Crossed / Paralleled | Vertical (in.) | Horizontal (in.) |
|---|---|---|
| Storm sewer (gravity) | 121 | 36 |
| Sanitary sewer (gravity) | 121 | 72 |
| Sanitary sewer (pressure) | 121 | 36 |
| Gas line (metal) | 18 | 120 |
| Reclaimed water main | 12 | 36 |
| Underdrains | 18 | 482 |
1 6” minimum separation is acceptable if water crosses above gravity storm or sanitary
2 distance from edge of granular filtration medium to water main
and as further specified below:
- Clearances When Water Main Installations Cross Other Utilities:
- Sanitary sewers, storm sewers, reclaimed water lines, and gas mains shall cross under potable water mains, whenever possible.
- One full length of water main pipe shall be centered at the crossing and its joints shall be leak-free.
- The crossing shall be arranged so that the storm, sanitary sewer, reclaimed water, or gas main joints will be equidistant, and as far as possible, from the water main joints.
- When crossing a metal gas main with 10 feet or less of separation, at a minimum, ductile iron water mains shall be polyethylene encased to a point 20 feet beyond the crossing, in both directions, per Department Standard Detail 2.05 – Polyethylene Encasement Installation.
- Clearances When Water Mains are Installed Parallel to Other Utilities:
- A minimum 6-foot horizontal separation shall be maintained between water mains in parallel installations with sanitary sewers or reclaimed water mains, and a minimum of 3-foot horizontal separation shall be maintained with storm sewers.
- In cases where the minimum horizontal separations cannot be maintained, the following criteria may be applied by the Department:
- The water main may be laid in a separate trench or on an undisturbed earth shelf located on one side of the storm or sanitary sewer at an elevation such that the bottom of the water main is at least 6 inches above the top of the storm or sanitary sewer (in profile view). Minimum horizontal-pipe wall-to-wall clearance of 36 inches shall be maintained.
- The water main should always be above the storm sewer or sanitary sewer (as viewed in profile view) and the joints staggered so as to be located as far as possible from the joints on the gravity or force main.
- If the water main must be below the storm sewer or sanitary sewer, the minimum 12-inch vertical clearance shall be maintained from the bottom of the storm or sanitary sewer to the top of the water main (as viewed in profile view), and a minimum 36-inch wall-to-wall pipe clearance maintained (as viewed in plan-view).
- Proposed water mains installed in parallel with any metal utility line that is cathodically protected, with less than 10-feet horizontal separation (pipe-wall to pipe-wall) shall have the ductile iron water main wrapped in polyethylene encasement for any length wherein the 10-feet separation requirement is not met and for a minimum of 20-feet beyond the limits of non-compliance.
When crossing or installing parallel to storm sewer and sanitary sewer mains, including gravity sewers and force mains, with less than the minimum clearances, the Developer shall protect the water main as shown on the plans or in a manner acceptable to the Department.
Department approval must be obtained for any variance from the above specified clearance and separation requirements.
2.2.2.5 Conflict Manholes
No water main shall pass through, or come into contact with, any part of a sanitary sewer manhole.
Effective August 28, 2003, regulations in the Florida Administrative Code (F.A.C. 62-555.314) were updated to include that water mains shall not be constructed or altered to pass through, or come into contact with, any part of a storm sewer manhole or inlet structure.
Where it is not technically feasible or economically sensible to comply with this requirement (i.e., where there is a conflict in the routing of a water main and a storm sewer and where alternative routing of the water main or storm sewer is not technically feasible or is not economically sensible), the Health Department may allow exceptions to this requirement (i.e., allow construction of conflict manholes); however, persons proposing to construct conflict manholes must first obtain a specific permit from the Health Department, in accordance with F.A.C. 62-555.314 Part V, that provides the technical or economic justification for each exception and provides alternative construction features that afford a similar level of reliability and public health protection, including specific requirements for the conflict manhole construction.
Additionally, the applicant must provide the following in the preliminary design report or drawings, specifications, and design data accompanying their permit application:
- Technical or economic justification for each conflict manhole.
- A statement identifying the party responsible for maintaining each conflict manhole.
- Assurance of compliance with the design and construction requirements in sub-subparagraphs a. through d. of F.A.C. 62-555.314 Part 3.
2.2.2.6 Property Frontage Requirements for Water Main Extensions
2.2.2.6.1 New Buildings
The customer shall front the entire width of their parcel with public water main if they are constructing a new building. Exceptions may be granted by the Department in dead-end right-of-way situations.
2.2.2.6.2 Existing Buildings
The customer shall front ten (10) feet of their parcel with public water main if there is an existing building onsite.
2.2.3 Valves
Valves shall be installed at intervals not to exceed 2,000 feet for transmission mains, 1,000 feet for residential distribution mains, and 500 feet for industrial and commercial distribution mains. There shall be a sufficient number of valves so that single lines in the network may be isolated from the remainder of the system. If construction is to be phased, a valve followed by one full length of pipe, a plug or cap and blow-off valve assembly must be installed at the end of each line that is to be continued. The valve, plug, and all pipe shall be restrained in conformance with this manual.
All tees shall be valved at the tee in 2 directions. All crosses shall be valved at the cross in 3 directions. A valve shall be located on each side of a jack-and-bore crossing and on each side of all water body crossings.
Unless at a tee or cross, valves shall be installed to line up with projected common property lines, if practical. Valve boxes, per current Department Standard Details, shall be installed with all valve installations ≥ 2”. For each valve installation, a Department-acceptable blue (purple if a reclaimed system valve) curb-marker shall also be installed, indicating the general location of the valve.
All valves over 24” must be evaluated and approved via written Water Department consent on a case-by-case basis.
2.2.3.1 Air Release Valves
Air release valves shall be located at high elevation points on the pipeline, where air pockets could disrupt the flow of water. Air release valves provided shall be the automatic-type, whose design is such that the outlet shall be installed above ground, in accordance with Department Standard Details 2.14A “Automatic Air Release Valve”, 2.14B “Automatic Air Release/Air Vacuum Valve”, and 2.15 “Pedestal for Automatic Air Release Valve”, and as required by the FDEP. Air release valves shall be stationed in both plan and profile views in the construction plans.
2.2.3.2 Blow-Off Valve Assemblies
Blow-off valve assemblies shall be installed at the dead-end of all non-circulating mains or at locations directed by the Department. Blow-off assemblies shall be installed in standard # 37 meter boxes set to finished grade. In order to protect it from vehicular traffic, the top of the blow-off-assembly shall be set to an elevation 6-in. below finished grade, inside the meter box. A blow-off valve assembly is not required where a fire hydrant can serve as a flushing location at a water main dead-end.
2.2.4 Fire Hydrants
2.2.4.1 Fire Protection
Fire hydrant spacing dimensions are measured along continuous Fire Department access roads as defined by NFPA 1 Section 18.2.3 2015. If the public fire hydrants meet the NFPA spacing requirements and satisfies the requirements set forth by the local authority enforcing NFPA requirements, any additional hydrants required to be installed by a private property owner shall be privately owned and maintained.
Fire hydrants shall be provided for detached one and two-family residences in accordance with both of the following:
- The maximum distance to a fire hydrant from the closest point on the building shall not exceed 600 ft.
- The maximum distance between fire hydrants shall not exceed 800 ft.
Fire hydrants shall be provided for buildings other than detached one and two-family residences in accordance with:
- The maximum distance between fire hydrants shall be 500 ft or as determined by the Water Department.
The basis of this standard is NFPA 1:18.5.2 “Detached One- and Two-Family Dwellings” and 1:18.5.3 “Buildings Other than Detached One- and Two-Family Dwellings”, 2018 Edition.
Fire hydrants shall be located at least 6-feet from the edge of pavement, including all entryways and driveways. At locations where this distance cannot be provided, bollards shall be required around the hydrant, per Department Standard Details, or as directed by the Department. A bi-directional, blue, reflective pavement marker shall be placed in the center of the traveled lane nearest each fire hydrant.
Per the Florida-specific code requirement of the Florida Fire Prevention Code (NFPA 1:18.5.7), the following minimum clearances to a hydrant shall be provided:
- A 36 in. (914 mm) clear space shall be maintained around the circumference of fire hydrants except as otherwise required or approved.
- A clear space of not less than 60 in. (1524 mm) shall be provided in front of each hydrant connection having a diameter greater than 2-1/2 in. (64 mm).
- Existing, previously approved hydrant installations shall be permitted to have clear spaces less than 60 inches.
Any exception to these distances must have the approval of the Fire Marshall.
2.2.4.2 Water Quality
Blow-off valve assemblies or fire hydrants shall be installed at the dead-end of all non-circulating mains or at locations directed by the Department. Blow-off assemblies shall be installed inside of standard #37 meter boxes set to finished grade, per the applicable Department Standard Details in this manual.
2.2.5 Service Connections
2.2.5.1 When and How Many Are Permissible
Individual water service connections will be required for each parcel for platted single-family residential subdivisions having public right of way. A master water service connection will be provided for single-family residential subdivisions having private right of way, apartments and
condominium complexes. An individual water service connection will be provided for each platted lot therein for platted industrial or commercial subdivisions.
New water services associated with a residential lot split (one lot being converted to a maximum of two lots) along 2 inch water mains are permissible without upsizing the water main. The Tampa Water Department will not issue commitments that extend existing 2” water mains when fire hydrant spacing / standards are not being met.
Commitments for ¾” and 1” residential water services may be issued by Department Customer Service personnel where the property is served by 6, 8, 10, 12 or 14 inch water mains. If the main serving the property is 4 inches or smaller in diameter, an engineering evaluation will be performed to determine water main adequacy to serve the customer. If the main serving the property is larger than those mentioned above, the request for service will be reviewed by Engineering Division personnel to determine the feasibility of a distribution main extension.
Before any distribution mains shall be installed by the Department or authorized by the Department to be installed or before any new commercial or industrial service is connected to an existing water main, such facilities shall include the necessary number of fire hydrants and fire hydrant appurtenances of a size, type, and spacing as specified within this document. The cost of such hydrants and appurtenances may be assessed to the customer.
2.2.5.2 Consecutive Water Supplies
If a customer is considered a consecutive water supplier, the customer is responsible for all associated regulatory compliance. Consecutive systems are defined as below or by FDEP, whichever is more current.
“Consecutive System” is a public water system that receives some or all of its finished water from one or more wholesale systems. Delivery may be through a direct connection or through the distribution system of one or more consecutive systems. (40 C.F.R. §141.2 (July 1, 2011))
“Public Water System” or “PWS” means a system for the provision to the public of water for human consumption through pipes or other constructed conveyances, if such system has at least fifteen service connections or regularly serves an average of at least twenty-five individuals daily at least 60 days out of the year. Such term includes: any collection, treatment, storage, and distribution facilities under control of the operator of such system and used primarily in connection with such system; and any collection or pretreatment storage facilities not under such control which are used primarily in connection with such system. Such term does not include any “special irrigation district.” A public water system is either a “community water system” or a “non-community water system.” See the Code of Federal Regulations (C.F.R.), Title 40, Part 141, Section 2.
2.2.5.3 Sizing
2.2.5.3.1 Meters and Service Lines
The goals of meter and service line sizing are as follows:
- Provide for each customer’s peak flow requirements at Water Department pressure standards
- Provide a standard sizing methodology to ensure fees and rates are consistently administered
- Maximize metering accuracy for revenue optimization and environmental stewardship reasons
Meter sizing is standardized for hydraulic and fee/rate administration reasons. Water Department staff may not be able to accommodate requests for smaller meters due to Water Department connection fees and/or Wastewater Department capacity fees, despite the fact a smaller meter may be hydraulically capable of meeting the customer’s demands. Water Department staff may not be able to accommodate requests for larger meters due to the Water Department’s water conserving rate structure that is sometimes dependent on meter sizing.
Services shall not be installed at a spacing less than every 3 feet along a water main to protect water main integrity.
Meter Sizing
Water meter sizes are determined by the Water Department using AWWA’s Manual of Water Supply Practices M22 “Sizing Water Service Lines and Meters”, the development type, and customer provided:
- Fixture counts (submitted on Water Customer Data Sheet)
- Plumbing plans
- Process water flow demands (submitted on Water Customer Data Sheet)
- Irrigation system plans (submitted on Irrigation Demand Work Sheet)
- Booster pump curves and cut sheets
The following tables present sizing standards based on the predominant development type and total fixture values.
Category 1: Small motels without restaurant or convention facilities; apartments, condominiums, town houses, & small trailer parks less than 300 units; single doctors’ offices; nursing homes; A.C.L.F. & boarding homes; convents; sanatoriums:
| Fixture Value Total | Meter Size | Peak Flow (gpm) |
|---|---|---|
| 0-45 | ¾” Displacement | 0-20 |
| 46-565 | 1” Displacement | 21-50 |
| 566-3000 | 1 ½” Displacement | 51-75 |
| 3001-7150 | 1 ½” Displacement | 76-100 |
| 7151-11000 | 2” Displacement | 101-125 |
| 11001-14000 | 2” Displacement | 126-150 |
| 14001-16000 | 2” Displacement | 151-160 |
| 16001-23750 | 3” Turbine or Compound* | 161-200 |
| 23751-38250 | 3” Turbine or Compound* | 201-300 |
| 38250-60000 | 3” Turbine or Compound* | 301-450 |
| 60001-67500 | 4” Turbine or Compound* | 451-500 |
| *A compound meter is required unless the application reviewer deems a turbine meter appropriate. The basis for this decision will be a case by case determination on the | ||
possibility of flow rates resulting in decreased metering accuracy.
Category 2: Other offices; hotels/motor inns; shopping centers; restaurants; public schools; public buildings; hospitals; industrial parks/attractions; large government installations; laundries; beauty shops; apartments, condominiums, townhouses, or trailer parks of 300 units or more; day care centers; churches:
| Fixture Value Total | Meter Size | Peak Flow (gpm) |
|---|---|---|
| 0-25 | ¾” Displacement | 0-20 |
| 26-105 | 1” Displacement | 21-50 |
| 106-355 | 1 ½” Displacement | 51-75 |
| 356-635 | 1 ½” Displacement | 76-100 |
| 636-1070 | 2” Displacement | 101-125 |
| 1071-2350 | 2” Displacement | 126-150 |
| 2351-3600 | 2” Displacement | 151-160 |
| 3601-10000 | 3” Turbine or Compound* | 161-200 |
| 10001-26000 | 3” Turbine or Compound* | 201-300 |
| 26001-48500 | 3” Turbine or Compound* | 301-450 |
| 48501-55500 | 4” Turbine or Compound* | 451-500 |
*A compound meter is required unless the application reviewer deems a turbine meter appropriate. The basis for this decision will be a case by case determination on the possibility of flow rates resulting in decreased metering accuracy.
Water demands that are not associated with one of the fixture types listed on the Customer Data Sheet shall be stated by the customer in the “process water or special water use” section of the Customer Data Sheet. The customer is responsible for specifying the “process water or special water use” peak flow demand. The application reviewer may require the customer to provide documentation substantiating the stated “process water or special water use” peak flow demand. Peak flow rates for any process water and special water use will be added to the fixture flow to determine peak demand.
The meter size for an individually metered single residential unit (single family residence, one townhome, etc.) will be ¾” unless the customer requests a larger meter. The customer shall substantiate the need for the requested larger meter size.
The peak flow of a booster pump will be utilized when sizing meters. If multiple pumps are proposed in parallel as part of a pumping system (duplex, triplex, etc.), each pump’s peak flow will be added regardless if one pump exists solely for redundancy purposes. If booster pumps with direct suction
taken from meter are proposed, the meter will be sized to provide peak pump flow rates; however, designing oversized pumps will not be considered sufficient reason to install a larger meter than would otherwise be necessary. The application reviewer may require the customer to substantiate booster pump sizing.
If an irrigation system is connected to a domestic water meter, the irrigation demands are typically not considered when sizing the domestic meter. In these circumstances, it is the customer’s responsibility to ensure the irrigation system demand can be supplied by the proposed domestic meter size and at the time of day the irrigation system is anticipated to operate.
Larger meters (>4”) will be sized by the Water Department’s Development Services Section in order to accomplish the above stated goals. Consideration will be given to the pressure drop through the meter (generally 5 psig or less), service piping flow velocity, and corresponding peak flow pressure drop and metering accuracy within the anticipated flow range.
For flows up to 500 gallons per minute, at the application reviewer’s discretion, turbine meters may be utilized for irrigation systems or other similar systems if the metering accuracy curve reflects a favorable metering accuracy at the anticipated minimum flow rate (i.e. the flow associated with the irrigation zone having the least demand or the flow associated with only one of the smallest plumbing fixtures turned on), only if the minimum flow is higher than 1% of its maximum recommended capacity for flow conditions.
Lawn irrigation meters will be sized based on the peak flow rate shown on the customer-submitted Irrigation Demand Worksheet. If a 2-inch or larger irrigation meter would be required, the customer shall submit irrigation plans and calculations with the application to substantiate the irrigation demand.
Combined domestic/fire service meter make, model, and sizing is at the City’s discretion considering flow requirements, pressure, and metering accuracy.
One (1) 1-inch meter will be provided for two duplexes, a tri-plex, or quad-plex, or any combination up to twelve (12) units on one property. Otherwise, these units will be considered as apartments and meter sizing will be determined by AWWA standards.
Meter Sizing Scenarios:

Meter sized as peak flow of pump Meter sized as 2x(peak flow of pump x) Meter sized as 3x{peak flow of pump x)
Service Lines
Service lines shall be sized according to Tampa Water Department Standard Details.
2.2.5.3.2 Fire Lines
Each applicant for commitment for fire protection service shall submit a completed Fire Flow Data Sheet.
The Water Department requires that all fire mains must be directly supplied by a distribution main of equal or larger nominal pipe size than the fire main being served.
For single family residential fire sprinkler heads (NFPA 13D Sprinkler Systems), customers may connect to an existing domestic or lawn irrigation system if there is an existing City service large enough for the sprinkler heads. There cannot be more than six sprinkler heads and the peak fire flow
cannot exceed 26 gallons per minutes. A check valve shall be installed by the customer on the fire sprinkler piping near the connection to the existing system. The customer shall submit to the City a completed Fire Flow Data Sheet, calculations, the number of sprinkler heads that would operate simultaneously, the peak gallons per minute demand per head, and the total fire flow demand.
Fire service line sizing shall be as determined by Water Department staff using hydraulic modeling and the criteria listed in Section 2.2.2.2.
Fireline Sizing Scenarios:
2.2.5.3.3 Equivalent Meter Sizes for Combined Domestic/Fire Services
A commitment for water service shall individually indicate the equivalent domestic meter and fire main size in addition to the combined meter size. This is for Wastewater billing purposes.
2.2.5.4 Site and Siting Requirements
Water service connections shall be installed on the address side of the property unless it is determined by the Director or their designee that such connection will provide better service and continuity from a different location.
New small meters (<3”) shall not be installed in sidewalks. New small meters shall be installed in a grassed area between the street curb and sidewalk, or on the customer side of the sidewalk even if said installation will be on private property. The Customer shall be responsible for providing a 5’x5’ grassed area for such installations on private property.
New irrigation meters may not be connected to the potable water system within the reclaimed water service area.
Meter locations will be determined by the Water Department. For single family residences, the meter shall be installed within two (2) feet of the side property line or as directed by the Department. For multiple residential units and lawn irrigation systems, the meter shall be installed where it can be best maintained and serviced.
If a proposed single family residence driveway is in the same footprint as an existing meter box, the Owner is responsible for meter relocation costs and providing a grassed area consistent with Department standards.
No trees may be present within 10 feet of unprotected public water facilities or within five feet of protected public water facilities.
If publicly owned water facilities must be installed within 10’ of a structure, the Owner must provide signed and sealed documentation from a Florida Professional Engineer stating the water facilities and structure do not structurally interfere with each other. Approval of these scenarios is at the discretion of the Water Department.
The Department may require the applicant to provide remote reading registers in accordance with Water Department standards for meters in inaccessible locations.
Per Florida Building Code – Building, 6th Edition (2017), Section [F] 403.3.2: In buildings that are more than 420 feet (128,000 mm) in building height, required fire pumps shall be supplied by connections to no fewer than two water mains located in different streets. Separate supply piping shall be provided between each connection to the water main and the pumps. Each connection and the supply piping between the connection and the pumps shall be sized to supply the flow and pressure required for the pumps to operate. Exception: Two connections to the same main shall be permitted provided the main is valved such that an interruption can be isolated so that the water supply will continue without interruption through no fewer than one of the connections.
New public fire service piping and / or ≥3” domestic services along state or county right-of-way are required to be within an easement dedicated to the City. New public fire service piping and / or ≥3” domestic services along City of Tampa right-of-way shall be within a grassed area acceptable to the Water Department. Grassed areas and easements are generally not required for private fire piping and private fire main backflow preventers.

Within the limits of the water pipeline trench, all trees and roots which have been designated for removal shall be labeled on the plans for removal and disposal by the Developer so as to allow for installation of the pipeline without hindrance.
All trees to be removed from City rights-of-way shall require a tree removal permit issued by the Parks Department. All trees to be removed from County rights-of-way shall require a tree removal permit issued by the County.
No trees shall be planted within 10 feet of the water main unless approved by the Water Department.
2.2.6.3 Dewatering
Subsurface water shall be kept 2 feet or more below the invert of the pipe until there is no danger of displacement of pipes or structures. All water collected and pumped shall be disposed of in a manner which will cause no health hazard, flooding, or nuisance to the surrounding area and in a manner so as not to degrade the water quality of surrounding water or violate any environmental ordinances or requirements. Water containing debris, sand, or heavy sediment shall not be discharged into the storm water system. All permits for the discharge of this water shall be obtained by the Developer from the appropriate regulatory agency. All dewatering discharging into surface waters of the state, as defined in Chapter 62-620 F.A.C., shall be tested and discharged in compliance with the “Generic Permit for the Discharge of Produced Ground Water from any Non-Contaminated Site Activity”. Results of pre-dewatering testing shall be maintained on the job site.
Dewatering operations shall be maintained until pipe placement is complete and the trench back-filled sufficiently to prevent movement or flotation of the pipe, including passing density tests if required.
2.2.6.4 Maintaining Service and Shutdowns
Existing water distribution systems must be kept in operation at all times. Where connections must be made to existing mains or when shutdowns are necessary to connect to active water mains, permission must be obtained and arrangements made with the Water Department before removing from service those mains that will be affected. Shutdowns must be held to a minimum in number and duration. No valve or other control device on the existing system shall be operated by the Developer without first obtaining approval from the Water Department. The Developer will be responsible for submitting a pre-valve request form with properly marked plans showing the proposed work with as much notice as possible, but at least four (4) weeks prior to the anticipated shutdown of the existing water system. The Water Department will attempt the requested shutdown and/or identify affected customers to determine shutdown feasibility at its sole discretion. Once the City’s pre-valve operation is complete, a shutdown request form with properly marked plans showing the proposed work must be submitted by the Developer at least two weeks prior to the anticipated shutdown of the existing water system. All pre-valve and shutdown requests must be made to the Water Department through the designated City inspector.
2.2.6.5 Trenching, Backfilling and Compacting
Trenching shall be conducted to the limits and grades shown on the plans or as directed by the Department.
The Developer performing the trench excavation shall comply with the Occupational Safety and Health Administration's (OSHA) trench excavation safety standards, including all subsequent revisions or updates to these standards as adopted by the Department of Labor and Employment Security (DLES).
The Developer shall consider all available geotechnical information in the design of the trench excavation safety system.
The use of trench-digging machinery will be permitted except in places where its operation will cause damage to other utilities, trees, buildings, or existing structures above or below ground, in which case hand methods will be utilized.
The trench width and trenching method may vary with, and depend upon, the depth of the trench and the nature of the excavated material encountered, but in any case shall be of ample width to permit the pipe to be laid and jointed and the backfill properly placed and compacted. The minimum width of unsheeted trench, at the bottom where the pipe is to be laid, shall be two (2) feet greater
than the nominal diameter of the pipe, except by consent of the Department. The maximum clear width of trench and the trench support system shall be in accordance with OSHA requirements.
Where sheeting and bracing are used in a trench, the trench width shall be adjusted accordingly. Trench sheeting shall be cut off at a minimum of one (1) foot above the top of the installed pipe and left in place. Alternatively, the sheeting may be left in place until the pipe has been laid, tested for defects, repaired if necessary, and the soil around the pipe compacted to a depth of two (2) feet over the top of pipe, at which time sheeting may be removed.
The trench shall be AWWA C-600 “Installation of Ductile-Iron Mains and Their Appurtenances” Type 2, as shown on the appropriate Department Standard Details, unless otherwise specified. The trench shall have a flat bottom conforming to the depth to which the pipe is to be laid. The pipe shall be laid upon sound soil, cut true and even, so that the barrel of the pipe will have equal bearing for its full length. Bell depressions of ample dimensions shall be dug at each joint to permit proper pipe jointing.
In the event the Developer excavates below the elevation required without approval from the Department, they shall refill the excavation with approved material and thoroughly consolidate. If, in the opinion of the Department, the trench bottom cannot support the pipe, a further depth and/or width shall be excavated and refilled to pipe foundation grade or other approved means shall be adopted to assure a firm foundation for the pipe.
All excavated material shall be piled in a manner that will not endanger the work and will avoid obstructing sidewalks and driveways. Gutters shall be kept clear or other satisfactory provisions made for street drainage. All material removed from the trench on an improved area shall be removed from the site by the Developer.
Material removed from an unimproved area may be reused if, in the opinion of the Department, it is suitable and if local conditions permit reuse. All materials suitable for reuse must be stored separate from the general excavated material. All backfill material must be approved by the Department prior to placement. If replacement backfill is required, the Developer must supply the material.
Backfilling and compaction shall be conducted in a manner as to prevent subsequent settlement and provide adequate support for the surface treatment, pavement, or structures to be placed thereon.
Backfill material shall be free from cinders, clay, ashes, refuse, organic matter, boulders, rocks or stones exceeding 2-inch diameter, or other material that in the opinion of the Department is unsuitable.
All trenches shall be backfilled and compacted by hand-tamping, from the bottom of the trench to the centerline of the pipe in lifts not to exceed six (6) inches (compacted thickness). Backfill material shall be deposited in the trench full width on each side of the pipe. From the centerline of the pipe to the specified grade, the pipe trench shall be backfilled and compacted by hand or by approved mechanical methods.
Soil consolidation through compaction shall be done in accordance with the requirements of the agency having jurisdiction. Unless requirements of the agency having jurisdiction are more stringent, all compaction shall conform to the following:
2.2.6.5.1 Impervious (Paved) Surface Areas
The space between the pipe and the trench sides shall be packed full by hand-shoveled earth, free from lumps, carefully deposited in layers not exceeding six (6) inches in depth. Such material shall be placed equally on each side of the pipe and, at the same time, tamped in a manner acceptable to the Department, until enough fill has been placed and compacted to the centerline of the pipe. From this point to twelve (12) inches above the pipe, backfill shall be placed and
compacted in uniform loose lifts no greater than six (6) inches to a density that is at least 98% of the maximum modified proctor density as determined by the Modified Proctor Density Test Method (ASTM D-1557). The balance of the soils backfilled from this point to the top of the trench shall be placed and compacted in loose lifts not to exceed twelve (12) inches to a density at least 98% of the maximum modified proctor density.
2.2.6.5.2 Pervious (Non-Paved) Surface Areas
The space between the pipe and the trench sides shall be packed full by hand-shoveled earth, free from lumps, carefully deposited in layers not exceeding six (6) inches in depth. Such material shall be placed equally on each side of the pipe, and at the same time, tamped in a manner acceptable to the Department, until fill has been placed and compacted from the bottom of the trench to the centerline of the pipe. From this point up to grade, backfilled soils shall be placed and compacted in uniform loose lifts no greater than twelve (12) inches, to a density that is at least 95% of the maximum density as determined by the Modified Proctor Density Test (ASTM D-1557).
2.2.6.6 Pipeline Installation
2.2.6.6.1 General
During shipping, delivery and installation of water main pipe, HDPE tubing, and accessories, materials shall be handled in such a manner as to prevent any damage. Particular care shall be taken not to injure pipe coatings. All pipe, fittings, valves, and other material shall be subject to inspection and acceptance by the Department after delivery and no broken, cracked, distorted, imperfectly coated, or otherwise damaged or unsatisfactory material shall be used. When a defect is discovered, the damaged portion shall not be installed. With the Department's approval, cracked DIP shall have the defect cut off at least twelve (12) inches from the break in the sound section of the barrel.
Installations shall be in accordance with manufacturer's recommendations and the appropriate AWWA Standards (C-600 “Installation of Ductile-Iron Mains and Their Appurtenances”) and as described in these technical specifications.
All connections to existing piping systems shall be made as shown or indicated on the plans after consultation and cooperation with the Department. No such connection shall be made until all requirements of these specifications as to tests, cleaning, flushing, and disinfection of new work have been met, and the planned cut-in to the existing line has been approved by the Department. Where connections are made between new work and existing water mains, the connections shall be made in a thorough manner using proper fittings and specials. Some such connections shall be made during off-peak hours if required by the Department.
2.2.6.6.2 Underground Pipelines
Proper implements, tools, and facilities satisfactory to the Department shall be provided and used. Pipe, fittings, valves, and appurtenances shall be carefully lowered into the trench piece by piece. Under no circumstances shall piping materials be dropped or dumped into the trench. Pipe and fittings shall be carefully examined for cracks and other defects while suspended above the trench immediately before installation in final position. If damage occurs to any pipe, fitting, valve, or piping accessory in handling, the damage shall be immediately brought to the Engineer's attention. The Department shall be consulted to prescribe corrective repairs or rejection of the damaged items.
Lumps, blisters, and excess coating shall be removed from the inside of the bell end and outside of the spigot end of each ductile iron pipe. The outside of the spigot and the inside of the bell shall be wire brushed and wiped clean, dry and free from oil and grease before the pipe is laid. Pipe joints shall be made up in accordance with manufacturer's recommendations.
Upon satisfactory excavation of the pipe trench and completion of the pipe bedding, a continuous trough for the pipe barrel and recesses for the pipe bells, or couplings, shall be excavated by hand digging. As the pipe is laid in the prepared trench, true to line-and-grade, the pipe barrel shall receive continuous, uniform support with no pressure exerted on the pipe joints from the trench bottom.
Pipe manufactured from materials that are classified as flexible for purpose of pipe design shall be bedded true to line-and-grade with uniform and continuous support from a firm base and installed in accordance with manufacturer's recommendations. Blocking shall not be used to bring the pipe to grade. Backfill material shall be properly placed and compacted to provide lateral restraint against deflection in the pipe diameter. Care shall be exercised to avoid contact between the pipe and compaction equipment.
The interior of the pipe shall be thoroughly cleaned of all foreign matter before being gently lowered into the trench and shall be kept clean during laying operations by means of plugs or other approved methods. Pipe 12-inches diameter and smaller may be cleaned by flushing in place under the supervision of the Department if in the Department's opinion the pipe contains dirt that can be so removed. In the Department's opinion, if the pipe contains dirt that cannot be removed by flushing, then the pipe shall be cleaned by swabbing and flushing before it is placed in the trench. Pipe greater than 12-inches diameter shall be thoroughly cleaned by appropriate means before being placed in the trench.
During suspension of work for any reason at any time, including the end of each workday, a watertight plug shall be placed in the end of the pipe last laid to prevent mud or other foreign material from entering the pipe. Sufficient backfill material shall also be placed over the pipe to prevent flotation.
Lines shall be laid straight and depth of cover shall be maintained uniformly with respect to finished grade, whether grading is completed or proposed at time of pipe installation. Pipelines shown on the plans to be laid at grade or with a specified slope shall be installed with the top of pipe or invert conforming to the required elevations, slopes, and alignment shown and with the pipe bottom uniformly and continuously supported by a firm bedding and foundation.
The work shall, at all times, progress with caution so as to prevent damage to underground obstructions, both known and unknown. If an obstruction is encountered which is not shown on the plans and realignment is necessary, the Department shall immediately be notified so that alterations to the plans can be made. The Developer shall notify the Department far enough in advance to allow realignment to be accomplished by deflection in the DIP pipe joints.
Pipe shall be laid with bell ends facing upstream, unless directed otherwise by the Department. Wherever it is necessary to deflect ductile iron pipe from a straight line, either in the vertical or horizontal plane, the amount of deflection allowed shall not exceed 80% of that allowed under AWWA C-600 “Installation of Ductile-Iron Mains and Their Appurtenances” for the type of joint being installed. Deflection will be allowed only after the pipe has been properly homed.
- Thrust Restraint
All plugs, caps, tees, bends, hydrant assemblies, and other fittings on water pressure pipelines shall be restrained for the required restraint lengths in accordance with the appropriate Restrained Length Table, as provided in Department Standard Details. Restrained joint lengths shall be called out in the profile views along with the beginning
Precast Thrust Blocks
Thrust restraint shall be accomplished with manufactured mechanical restraint devices. The use of thrust blocks will be considered and approved by the Water Department on a case-by-case basis. Generally, thrust blocks will not be approved unless the Water Department determines mechanical restraint is not feasible. If concrete thrust blocks are required during installation, precast concrete thrust blocks shall be manufactured to the dimensions shown in the Department Standard Details. The concrete for thrust blocks shall consist of a uniform mix of Portland cement, sand, and gravel. The mix shall be proportioned to provide a dense concrete with a minimum compressive strength of 3,000 psi in 28 days. All material used in mixing concrete shall meet Florida Department of Transportation specifications.
Joints
The joints of all pipelines shall be made absolutely tight. The particular joint used shall be acceptable to the Department prior to installation. The gasket material for the joint shall be properly positioned before the pipe is lowered into the trench. The joining of the pipe shall proceed in accordance with the manufacturer's requirements.
Push-on Joints
In making up the push-on type joint, the gasket shall be placed in the socket of the mating bell with the large round end entering first, so that the groove fits over the bend in the seat. The spigot end of the pipe shall be cut and beveled as necessary and thoroughly brushed and cleaned with a wire brush. A thin film of manufacturer-approved lubricant shall be applied to both surfaces (inside surface of bell and outside surface of spigot) to be mated and homed. The spigot end of the pipe shall be placed in alignment with the bell end of the pipe to which it is to be joined. The joint shall be made up by exerting sufficient force on the bell end of the pipe to be homed, so that its spigot end is moved past the gasket until it seats, in accordance with manufacturer's recommendations. Backhoe buckets or excavation equipment shall not be applied directly to the pipe. Any deflections required shall be made after the pipe joint is assembled.
Mechanical Joints
Where shown on the plans, or where in the opinion of the Department, settlement or vibration is likely to occur, all pipe joints of pressure pipelines shall be bolted mechanical type as specified herein.
Mechanical joints shall be made up using high-strength, low-alloy steel bolts and EPDM rubber gaskets having either plain or duck tip as recommended by the manufacturer. All types of mechanical joint pipes shall be laid and jointed in full conformance with the manufacturer's recommendations. Only especially skilled workers shall be permitted to make up mechanical joints.
Mechanical joints shall be centered in the bells. Soapy water or a manufacturer-approved pipe lubricant shall be brushed over the gasket just prior to installation. The gasket and gland shall be placed in position, the bolts inserted, and the nuts tightened finger-tight. Mechanical joints shall be assembled in accordance with AWWA Standards. The joint bolts shall be tightened on opposite sides of the pipes by means of a torque wrench in such a manner that the gland shall be brought up evenly into the joint. The following range of bolt torques shall be applied:
| Bolt Size (inches) | Range of Torque |
|---|---|
| ¾” diameter | 85 to 95 ft-lbs |
| 1” diameter | 95 to 100 ft-lbs |
If effective sealing is not obtained at a maximum torque listed above, the joint shall be disassembled and reassembled after thorough cleaning. If the joint is defective, it shall be cut out and entirely replaced or, if authorized by the Department, the defective joint may be repaired by a suitable clamp.

2.2.7 Requirements for Acceptance
2.2.7.1 General
All Developer-installed water facilities must be constructed in accordance with all applicable Department Standards and Specifications, Standard Details, and City of Tampa Code requirements. A representative of the Department will inspect the construction to assure compliance.
2.2.7.2 Testing
The Department will require the Developer's Engineer of Record to perform the required tests to assure that all pipe installed including service lines meets the Department's standards.
The required tests are as follows:
2.2.7.2.1 Hydrostatic Testing
Pressure Testing
All newly laid water pipe, including fittings, valves and service lines, shall be pressure tested in accordance with AWWA C-600 “Installation of Ductile-Iron Mains and Their Appurtenances” for DIP.
The Developer shall furnish, install, and operate all necessary equipment and instrumentation (pressure gauges, volume gauges, hoses, pumps, test pipe, test fittings, etc.) required for flushing and testing of the piping systems; all such equipment and devices and their installation shall be approved by the Department. Pressure gauges shall be marked in graduated increments that do not exceed 2 psi. Gauges used to measure the volume of water necessary to raise post-test line pressure back to the highest pressure achieved during the test duration will be marked in graduated increments which do not exceed 5 ounces.
If requested by the Department, the Developer shall furnish to the Department certified test data for any gauges or recorders used for testing purposes. For testing purposes, the Developer shall have access to water supplied by the Department. Testing shall be conducted in the presence, and to the satisfaction, of the Department as a condition precedent to the approval and acceptance of the system. No less than 3 days’ notice shall be given prior to start of such tests; such testing shall not be scheduled until preliminary testing by the Developer has indicated that the test section is ready for testing. The schedule and procedures for testing shall be determined by the Developer and reviewed with the Department prior to testing.
The duration of each pressure test shall be at least 2 hours with a minimum test pressure in excess of 150 psi. At no time shall the test or line pressure exceed 190 psi. Test pressure shall not vary by more than ±5 psi for the duration of the test. If required by the Department, pump test equipment will be equipped with pressure relief valves pre-set to 190 psi. Each valved section of pipe shall be slowly filled with water and a pump shall be connected to the low point of the section being tested.
Before conducting the test, the Developer shall backfill all pipe unless the Department directs certain joints or connections to be left uncovered.
Before application of the test pressure, all air shall be expelled from the pipe. To accomplish this, taps will be made, if necessary, at points of highest elevation and afterward tightly stopped with tapered brass plugs, all at the Developer's expense.
At the end of the 2-hour test period, the Developer shall be required to pump the lines back up to the highest pressure obtained during the duration of the test period.
Pressure tests shall be made between valves to demonstrate the ability of the valve to sustain pressure. All piping systems shall be tested in accordance with these test methods, in addition to any other tests required by local plumbing codes or building authorities. At the option of the Department, flow meters and/or pressure gauges used on hydrostatic testing equipment with approved strip or round chart recorders shall be supplied by the Developer. Tests shall be made in sections not to exceed ½ mile.
Throughout the duration of the test, the Developer is required to maintain a minimum pressure in excess of 150 psi. The Developer is advised that, should the test pressure fall to or below 150 psi any time during the 2-hour test, the test will be considered invalid and a retest will be required. Therefore, it is advised that the Developer should pump water into the line as the test pressure approaches 150 psi.
The Department may allow pressure testing of multiple sections during one continuous 2 hour test period as long as the Developer can justify that each valved section shall be tested to the satisfaction of the Department.
The Developer is warned that pressure testing against existing valves is done at their own risk. Failure of these valves to hold test pressure shall not relieve the Developer of the pressure testing requirement.
All exposed pipe, fittings, valves, and joints shall be carefully examined for leaks. Any cracked or defective pipe, fittings, valves, or other appurtenances discovered as a consequence of the pressure test shall be removed and replaced with acceptable material, at the Developer’s expense. All leaking or defective joints shall be repaired, corrected, or replaced, at the Developer’s expense. After all necessary replacements and corrections have been made the test shall be repeated to the satisfaction of the Department.
If the pipeline fails the pressure test twice, then the Developer shall be required to retest the pipeline and provide to the Department certification by a Professional Engineer registered in the State of Florida that the pipeline has passed the test in accordance with these standards before the Department will witness another test.
Leakage Testing
Concurrently with pressure testing, pipelines shall be subjected to leakage tests.
Leakage measurements shall not be started until a constant test pressure has been established in excess of 150 psi.
The duration of each leakage test shall be at least 2 hours and the test pressure shall be as specified for the pressure tests. Leakage is defined as the quantity of water that must be supplied into the pipeline or section thereof to maintain the established test pressure after the air in the pipeline has been expelled and the pipe filled with water plus that volume of water required at the conclusion of the test to bring the line pressure back up to the highest pressure obtained during the duration of the test period.
The maximum allowable leakage shall not exceed the number of gallons per hour (gph) as determined by the following formula:
LL = SS x sqrt(P) / 148,000
where: L – allowable leakage, gph
- S – length of pipeline tested, feet
- D – pipe nominal diameter, in inches
- P – average pressure during the test, psi
The allowable leakage equation given above is based on 18-foot lengths of pipe and shall be adjusted accordingly for other pipe lengths supplied.
AWWA C-600 “Installation of Ductile-Iron Mains and Their Appurtenances” includes a table which provides the allowable amount of leakage in gallons per hour for various sizes of pipe under different test pressures. The Developer is referred to that table as an alternative to calculating the values using the above formula.
When leakage exceeds the allowable limit, the defective pipe or joints shall be located and repaired. All visible leaks are to be repaired regardless of the amount of leakage. If the defective portions cannot be located, the Developer shall remove and reconstruct as much of the work as is necessary until the leakage is within the allowable limits. Such corrective work or damages to other parts of the work as a result of such work shall be at the Developer's expense.
Leakage detection at mechanical joints shall be stopped by tightening the gland (not to exceed required torque) and leaking slip joints shall be cut out and entirely replaced or if permission is given by the Engineer, with technical assistance from the City of Tampa Water Department, it may be repaired by a suitable clamp. Any cracked or defective pipe, fittings, valves, or hydrants discovered as a result of this test shall be removed and replaced by the Developer with sound material and then the test shall be repeated.
If the pipeline fails the leakage test twice, then the Developer shall be required to retest the pipeline and provide to the Department certification by a Professional Engineer registered in the State of Florida that the pipeline has passed the test in accordance with these standards before the Department will witness another test.
2.2.7.2.2 Disinfection
The Developer shall disinfect the water mains in accordance with the applicable section of the latest AWWA C-651 “Disinfecting Water Mains”, as summarized below. The Developer, if directed, shall use the method specified by the Engineer.
Methods of Chlorination:
- Slug Method
- The slug method consists of:
- a) Completely filling the main in order to remove air pockets.
- b) Flushing the main with a velocity of not less than 2.5 feet per second (fps) in order to remove particles.
- c) At a point not more than 10 feet downstream of the water source flushing the new main, chlorine is to be continuously injected for a sufficient period to develop a solid column or "slug" of chlorinated water.
- d) The slug of chlorinated water is to move through the main, exposing all interior surfaces to a chlorine concentration of approximately 100 mg/L for at least a 3-hour period.
- Continuous Feed Method
The continuous feed chlorination method consists of:
- Completely filling the main to remove air pockets.
- Flushing the main with a velocity not less than 2.5 fps.
- At a point not more than 10 feet downstream of the water source flushing the new main, injecting chlorine in the new main at a constant rate sufficient to establish a 25 mg/L chlorine concentration throughout the main.
- Minimum amount of chlorine required for each 100 foot section of pipe of various diameters:
| Pipe Diameter | 100% Chlorine (lb) | 1% Chlorine Solution (gal) |
|---|---|---|
| 4" | 0.013 | 0.16 |
| 6" | 0.030 | 0.36 |
| 8" | 0.054 | 0.65 |
| 12" | 0.120 | 1.44 |
| 16" | 0.217 | 2.60 |
- The chlorinated water shall be retained in the main for at least 24 hours and have a residual of not less than 10 mg/L free chlorine prior to flushing.
2.2.7.2.3 Sampling
Upon completion of the hydrostatic test and disinfection, and at least one week in advance of the sampling, the Developer shall contact the Department's Contract Administration Department to request coordination and inspection for bacteriological testing. The Developer shall employ a private, City-approved testing lab for the required Bacteriological sampling and testing.
The Developer shall install sample taps, per Department Standard Details, on the new main and at the end of each new branch of the piping system. The Developer shall flush the chlorinated disinfection water from the piping system until a free chlorine residual of 1.0 to 1.5 mg/L is maintained.
Due to FDEP requirements, the Developer’s Contractor may be required to remobilize to the site thirty to forty-five days after the samples have been cleared to perform necessary meter transfers and/or cut-and-plugs.
All drilling and tapping equipment shall be disinfected as directed by the Department.
After completing the testing and sterilizing, and regardless of ground conditions, all sample taps and corporation stops shall be removed from the water main and replaced with tapered brass plugs.

Burning of brush or debris is not permitted.
2.2.7.3.2 Repair and Resurfacing
Where street paving, driveways, sidewalks, or curb and gutter are disturbed, restoration shall be made to a condition at least equal to the original. All materials used for restoration shall conform to standard requirements of that particular agency responsible for roadway maintenance where construction takes place. All restoration work shall also meet the requirements of both the permitting agency as well as the Department. The Developer shall determine any requirements and procedures, other than those set forth herein, which may affect the type, quality, and method of carrying out the restoration of the areas to be restored to the satisfaction of the Department.
Base material shall be of the type removed or of equal or greater structural strength as determined by the Engineer. Existing base material from the excavation shall not be reused as base material, but may be used as a stabilizer, or for trench backfill after removal of existing asphalt, unless it is determined by the Department to be unsuitable.
Edges of pavement shall be mechanically sawed to provide a neat, straight edge to the width shown on the construction plans, or greater if necessary, prior to replacement. Base material shall be placed to the depths required by the permitting agency and thoroughly compacted to the density required by the Department or to the standard of the governing permitting agency.
The Developer shall pay careful attention to the proper reconstruction of the pavement adjacent to the gutters and at street intersections to obtain satisfactory drainage to inlets from the intersecting streets. Pavement replacement shall be with the same type of materials as removed and installation methods and procedures shall comply with the appropriate procedures established by the FDOT Standard Specifications, or the appropriate permitting agency.
In the absence of governing agency requirements, where asphaltic concrete overlays are performed, the overlays shall be 1-inch thick over the pipe trench area, or as directed by the Department, and provide smooth transition between existing pavements and overlay pavement.

METHOD A
POLYETHYLENE TUBE IS CUT INTO LENGTHS APPROXIMATELY TWO FEET LONGER THAN THE PIPE SECTION AND PLACED AROUND IT. AFTER THE PIPE JOINT IS ASSEMBLED, THE POLYETHYLENE TUBE IS MADE TO OVERLAP THE JOINT AND THE OVERLAP SECURED IN PLACE. SINCE THE TUBE IS CONSIDERABLY LARGER THAN THE BARREL OF PIPE, IT IS MADE TO FIT SNUGLY BY FOLDING OVER AT THE TOP AND SECURING WITH TAPE EVERY 24" ALONG THE PIPE SECTION.
METHOD B
POLYETHYLENE TUBE IS CUT ONE FOOT SHORTER THAN THE LENGTH OF THE PIPE SECTION. AFTER PLACEMENT OF THE PIPE, IT IS FOLDED AND SECURED SNUGLY OVERALL. A THREE FOOT LENGTH OF POLYETHYLENE TUBE PLACED OVER THE END OF THE PRECEEDING SECTION IS THEN PULLED IN PLACE OVER THE JOINT AFTER ASSEMBLY AND SECURED.
METHOD C
POLYETHYLENE SHEET IS CUT TO A LENGTH TWO FEET LONGER THAN THE PIPE SECTION. THE SHEET IS WRAPPED AROUND THE PIPE SO THAT IT OVERLAPS CIRCUMFERENTIALLY OVER THE TOP QUADRANT OF THE PIPE, THEN SECURED. AFTER JOINT ASSEMBLY, THE SURPLUS LENGTH OF POLYETHYLENE FILM IS SECURED AROUND THE JOINT, PROVIDING AN OVERLAP OF EACH JOINT TAPE AT EACH JOINT AND AT 3' INTERVALS IN BETWEEN.
