3.3.10 Water, Wastewater, and Reclaimed Main Extension Examples
3.3.10.1 General — Water, wastewater, and reclaimed water mains shall be sized to
provide the capacity required by the Development in accordance with the
Water and Sewer Study Guidelines as required in accordance with Section
5.4 (Sizing Water Mains), Section 6.3 (Sizing Wastewater Mains), or
Section 7.2 (Sizing Reclaimed Water Mains). In no case shall the main
size be less than the minimum main size required, even if the capacity
requirement is less than the minimum size.
3.3.10.2 The examples in this section provide schematic configurations for
situations requiring a main extension, but examples may not address all
possible scenarios requiring extension.
3.3.10.3 Full Frontage — Frontage Mains shall be extended across the entire
Frontage of the Developing Property's lot to allow for service to future
Development. Depending upon the location of water, wastewater, or
reclaimed water infrastructure, the full Frontage may be along the side or
rear of a Developing Property's lot and not along the street Frontage. In
these circumstances, the City's Development Services Department —
Water Section will determine which side of the lot is considered Frontage.
The following examples outline several common scenarios:
3.3.10.3.1 An existing wastewater main Point of Connection may be
located near the rear of a Property, due to topography. In
this case, the wastewater main Frontage would be the rear of
the Property, and the wastewater extension would be
required across the entire Property's rear Frontage.
3.3.10.3.2 If existing water, wastewater, or reclaimed water
infrastructure is adjacent to a Property's side Frontage, the
Development Services Department — Water Section may
consider the side of the Property to serve as the Frontage for
the infrastructure extension.
3.3.10.3.3 Service area limitations may preclude extension across a
Property's full Frontage. Depending upon the location of the
existing infrastructure's Point of Connection, the
Development Services Department — Water Section may
require the side or rear of the Property to serve as the water,
wastewater, or reclaimed water's Frontage.
3.3.10.3.4 The foregoing situations are not all-inclusive but are
included to outline situations where the infrastructure
Frontage may not be warranted along a Property's street
Frontage.

3.3.10.5 Parallel Main Concept —A parallel main extension shall be required for
Service Lines exceeding 55 feet (i.e., long service lines), crossings at non -
City Rights -of -Way, a main size larger than 15 inches, or a main depth 15
feet or deeper will require an extension of a parallel main. The City will
review proposed locations for Point of Connections to existing mains to
ensure that the connection benefits the overall water/wastewater/reclaimed
water system and does not adversely impact its existing Customers.
3.3.10.6 Single Frontage Developments — Developments with Frontage along only
one City Right -of -Way will require a main extension from the Point of
Connection across the Property's full Frontage. See Figures 3-1 to 3-13
for extension examples for Developments with single Frontage.
3.3.10.7 Multiple Frontage Developments — Developments with street Frontage
along more than one City Right -of -Way, or water, wastewater, or
reclaimed water infrastructure Frontage along more than one side of the
lot, will require a main extension from the Point of Connection across the
Property's full Frontage(s) that is proposed to have a Service Line or a
connection for an On -Site Main extension. No extension is required for
Frontage(s) where a Service Line or main connection is not proposed,
unless a second Point of Connection is required to meet the capacity
requirements of the Water and Sewer Guidelines. See Figures 3-14 and 3-
15 for extension examples for Developments with multiple Frontage.
3.3.10.8 Wastewater Mains Along Creeks, Rivers, Water Features — Developments
containing an existing wastewater main located along a creek, river, water
feature, or other topographic low, require a wastewater main extension to
adequately provide service to upstream properties. See Figures 3-16 to
3-18 for extension examples for these Developments.
3.3.10.9 Shared Access Development — When connecting a Property to a water or
wastewater main in accordance with a Shared Utility Easement and

FORT WORTH
CITY OF FORT WORTH WATER DEPARTMENT INSTALLATION POLICY AND DESIGN CRITERIA
1. General Guidelines
A Water and Sewer Study of the immediate and surrounding area of Development is
needed to evaluate the adequacy of existing and proposed facilities for present and future
needs. This document is meant to serve as a general guideline for preparing and
submitting demand/loading & layout and comprehensive studies. Every Study is unique;
therefore, this guide is not designed to incorporate all possible design approaches. An
application of sound judgment is necessary in preparing the comprehensive Study. A list of
major goals that each Study must accomplish is provided below.
Maior Study Goals:
• Describe the existing conditions and show the proposed facilities
• Calculate the demand/loads expected to be generated by the proposed
Development
• Demonstrate the impact of the proposed Development
• Describe the potential issues associated with the proposed Development (if
there are any) or demonstrate that the existing system is not likely to be
impacted by the proposed Development
• Provide figure (s) and table (s) summarizing the existing conditions,
identifying problems (i.e., potential issues) and proposed solutions
• Show how adjacent undeveloped properties are not blocked from future access to
utilities (Please refer to the of "Installation Policy and Design Criteria for Water,
Wastewater, and Reclaimed Water infrastructure" for more information.
• Provide recommendations for improvements needed to adequately
serve the proposed Development
• Justify the water meter sizes and quantities are consistent with the
Study demands
This guide recommends minimum requirements for submitting either a demand/loading &
layout or comprehensive Study. Different approaches can be utilized as long as the primary
goals of the demand/loading and Study are accomplished. However, required policies and
procedures, i.e., design criteria, are not negotiable and must be used.
The demand/loading & layout and comprehensive studies serve the City of Fort Worth
Water Department as a historical record of the assumptions and analysis methods utilized at
the time the proposed Development is submitted. Please be sure to include any and all
pertinent information that may not be known to future readers of this document. The
document should be prepared as though the reader does not have any previous knowledge
of the Development and any associated issues negotiated during the Development process.

httns://www.tceq.texas.gov/rules/indxndf.html.
4.1 Water Model Basics,
The water model was developed and is maintained using the Innovyze InfoWater software. A
separate pressure plane specific model has been developed for each major Service Area
(Northside, Southside, Westside, etc), which includes all the sub pressure planes as well. For
example, the Northside water model includes Northside 2, 3, and 4. The South side model
includes Southside 2, 3, and 4. This is provided to make it easier to analyze Developments that
may be on the border of two pressure plane boundaries.
NO REVISIONS TO THE EXISTING PIPING NETWORK OR OPERATIONAL PARAMETERS IS
ACCEPTABLE. Any revisions of existing network pipes, valves, or operating parameters will
result in the Study being rejected and returned without review.
Request the pressure plane specific water model from Fort Worth Water Department.
Contact WPD@fortworthtexas.Rov. Before every Study the applicant should check with
Department to ensure the appropriate model is utilized.
Existing model demands are Max Day Demands. Each existing demand in the model has a
diurnal pattern specific to the overall water use pattern within each pressure plane.
Existing wholesale water demands may be constant or have a demand pattern that reflects
APPENDIX A 191 AUGUST 2026
FORT WORTH
CITY OF FORT WORTH WATER DEPARTMENT INSTALLATION POLICY AND DESIGN CRITERIA
their specific use pattern.
III. Insert the proposed node demands as Maximum Day Demands. Apply the Development
specific demand pattern shown at the end of Section 4. This pattern represents typical use
patterns of new Developments and includes a 2.0 multiplier at the peak hour. Using this
pattern allows the engineer to model maximum day demands as well as maximum hour
conditions for proper sizing of pipes. For some industrial Developments, an alternate use
pattern may be proposed if the engineer can show historical data from similar projects.
IV. Fire flow will typically be 1,000 gpm for single family lot residential and 1,500 gpm for
commercial and multi -family. The fire marshal may require an even higher flow rate
depending on the type of Development and construction type. Fire flow duration is 3 hours.
Use the fire flow diurnal pattern at the end of Section 4. Multiple locations may need to be
tested and reported if there are multiple pressure planes serving the Development, multiple
fire flow requirements (I.e. residential and commercial) and if there are multiple dead-end
lines.
V. Please include a copy of the diurnal patterns used in the Development (including the Fire
Flow pattern) in the report.
VI. Study for Phased Development: As for large Development with multiple phase
construction, water and sewer Study requirements should meet the minimum standards
for each phase of construction.
VII. Hazen -Williams coefficient (C factor) should be assumed 130 for the proposed water lines.
VIII. All water model files must be submitted in (*.inp) format
4.2 Modeling Scenarios. Analysis and Exhibits
The exhibits listed below are a minimum requirement for water comprehensive studies.
Additional mapping may be required to demonstrate that the Study objectives (discussed in
Section 1) are met. The maximum figure size shall be 11 X 17. Use different colors for pipes
and nodes, and label them clearly.
When running the model simulations, the existing water model diurnal curves provided by the
City shall not be edited or used for proposed Developments. Any proposed Developments
shall use a unique, Development -only diurnal curve that represents the correct 2.0 multiplier
for maximum hour required.
4.2.1 Simulation #1 — Base Condition: Maximum flay Demand with Existing
Develonments
• Run the existing model, and display results for all nodes and pipes in Exhibitl.
• Provide Pipe and Node I.D.'s legibly on this map. Display the results for all the nodes and
pipes for the minimum pressure experienced in the area being developed.
• The existing system network map (i.e., Exhibit 1, Existing Water System Network Map)
shall include the project area and an appropriate radius around the project (typically
APPENDIX A 192 AUGUST 2026
FORT WORTH
CITY OF FORT WORTH WATER DEPARTMENT INSTALLATION POLICY AND DESIGN CRITERIA
0.1 to 0.5 mile). For example, draw a 0.1 mile radius if the project is in or near a
developed area. Draw at least a 0.5 mile radius around the project if the project is
located in a rural area.
4.2.2 Simulation #2: Maximum Dav Demand with Proposed Development
• Add the Maximum Day Demands (MDD) of the proposed system Development to the
existing model.
• Assign the standard Development diurnal pattern (see end of Section 4) to the proposed
demands. The standard pattern includes a 2.0 multiplier which represents maximum hour
demand. Commercial patterns or industry specific patterns may be different than
residential. If a pattern different from the standard pattern is proposed, include historical
data based justification in the report as an appendix. A different pattern should be used
only if maximum hour demand is larger than maximum day + fire flow demand.
• Adjust the proposed pipe sizes to eliminate any low pressure (lower than 40 psi), head loss
above 5 ft/1000 ft, and velocity above 5 ft/s (for pipes 12 -inches and smaller) and head loss
above 7 ft/1000 ft, and velocity above 7 ft/s (for pipes 16 -inches and larger).
• Run the model and analyze results. Report the minimum pressure, maximum velocity, and
head loss obtained compared to the Installation Policy and Design Criteria for Water,
Wastewater, and Reclaimed Water infrastructure for City of Fort Worth.
Display minimum system pressure during 24 hours for all nodes in an exhibit including
node Identification No. and corresponding pressure (i.e., Exhibit2a).
Display maximum velocity and head loss during 24 hours for all pipes in an exhibit
including pipe Identification No., corresponding pipe sizes, and corresponding velocity
and head loss (i.e., Exhibit 2b).
4.2.3 simulation #3: Maximum Dav + Fire Flow Demand with Pronosed Develonment
• Simulation #3 extends the work that was done in simulation #2. In the second simulation,
the node with the lowest pressure in a well looped system (typically the highest elevation)
shall be selected within the Development. This node is taken as the critical fire node and
shall be used as the fire node to which the fire flow demand is applied. Some
Developments with multiple pressure planes, multiple Development types or dead-end
pipes may have to prove adequate fire flow performance at more than one junction.
• Assign the Fire Flow Development pattern to the proposed Fire Flow Demand applied to
the fire node.
• Adjust the proposed pipe sizes to eliminate any low pressure (lower than 20 psi) and
velocity above 10 ft/s in all pipes.
• For fire flow analysis, prepare mapping that shows the available pressure at each node and
pipe velocity during the fire flow analysis with the full fire flow demand applied.
• Run the model and analyze results. Report the minimum pressure and maximum velocity
obtained compared to the Installation Policy and Design Criteria for Water, Wastewater,
APPENDIX A 193 AUGUST 2026
FORT WORTH
CITY OF FORT WORTH WATER DEPARTMENT INSTALLATION POLICY AND DESIGN CRITERIA
and Reclaimed Water infrastructure for City of Fort Worth. r
Display minimum system pressure during 24 hours for all nodes in an exhibit including
node Identification No. and corresponding pressure (i.e., Exhibit3a).
Display maximum velocity during 24 hours for all pipes in an exhibit including pipe
Identification No., corresponding pipe size, and corresponding velocity (i.e., Exhibit3b).

MAYOR AND COUNCIL COMMUNICATION
7.1.33 WATER/WASTEWATER INSTALLATION POLICY DESIGN CRITERIA UPDATE
DATE: 08/11/26 M&C FILE NUMBER: M&C 26-0659
1014J_1:1I l ►Ii VJ/evi14,7
SUBJECT
(ALL) Adopt Resolution Adopting the 2026 Installation Policy and Design Criteria for Water,
Wastewater and Reclaimed Water Infrastructure
RECOMMENDATION
It is recommended that the City Council adopt the attached resolution adopting the
2026 Installation Policy and Design Criteria for Water, Wastewater and Reclaimed Water
Infrastructure.
DISCUSSION
The purpose of this Mayor and Council Communication (M&C) is to recommend the adoption
of the attached resolution adopting the 2026 Installation Policy and Design Criteria for Water,
Wastewater, and Reclaimed Water Infrastructure. In 2017, pursuant to M&C C-28333, the City of
Fort Worth (City) executed City Secretary Contract No. 49554 with Kimley-Horn and Associates
Inc. (Kimley-Horn) to perform engineering consulting services to update the City's Installation
Policy and Design Criteria for Water, Wastewater, and Reclaimed Water Infrastructure (Water
Criteria Manual). The Water Criteria Manual was last updated in 2019. On November 17, 2023,
the City executed City Secretary Contract No. 60498 with Kimley-Horn to update the Water
Criteria Manual.
The updates to the Water Criteria Manual incorporate improvements and revisions, some of
which were needed to comply with House Bill 3167, 86th Texas Legislature, Regular Session. The
changes include the following items:
• Changes to all sections to clarify the Water Criteria Manual
• Section 2 - Added definitions for Water Department - Strategic Operations and
Wastewater Capacity Charges
• Section 3 - Updated the policy regarding extensions, cost participation and easements
• Section 3 and Section 5 - Added new technological references for advanced metering
infrastructure (AMI)
• Section 4 - Updated the procedure regarding miscellaneous contract criteria, added
wastewater capacity charge, and revised backflow references
1 of 3
FORT WORTHfU
• Section 5 - Added updates to demand and headloss criteria and backflow language to
the design criteria for water systems
• Section 6 - Amended the design criteria for wastewater mains regarding manhole
adjustments, clarified alignment walk requirements, standard wastewater main
location, and on -site sewage facilities requirements
• Section 8 - Revised the requirements for drawings to include easement requirement to
be by separate instrument when not included on the plat
• Section 9 - Updated the variance process language by setting a waiver expiration date
and adding Development Service's Director's approval
• Added language addressing data centers. New language requires a data center
developer to obtain a non -significant industrial user permit and declares that data
centers will be considered light industrial and must utilize a closed loop cooling system
As part of this work, City staff compared Fort Worth's existing water, wastewater and reclaimed
water policy and design criteria with similar policies adopted by other large cities in Texas. As
City staff considered changes to the Water Criteria Manual, City staff engaged stakeholders to
vet the changes from the perspective of the engineering and development community.
Stakeholder review meetings with the Development Advisory Committee (DAC) occurred in
October 2021, June 2022, March 2023, and January 2024. A summary of the improvements and
revisions to the installation policy and design criteria were presented to the DAC in June 2026.
Staff recommends that the City Council adopt the attached 2026 Installation Policy and Design
Criteria for Water, Wastewater and Reclaimed Water Infrastructure, with an effective date of
August 11, 2026.
This MSC does not request approval of a contract with a business entity.
FISCAL INFORMATION/CERTIFICATION
The Director of Finance certifies that approval of this recommendation will have no material
effect on City funds.
