2024 Water Conservation Plan
This Water Conservation Plan has been developed in accordance with the
requirements of 30 Texas Administrative Code (TAQ Chapter 288. A copy of the
version of 30 TAC Chapter 288 in place at the time of this Plan preparation is included
in Appendix B.
2024 Water Conservation Plan
City of Wylie
LOO INTRODUCTION
City of Wylie is a Member City of the North Texas Municipal Water District (NTMYV[J).
' This Plan was developed following TCEQ guidelines and requirements governing the
development of water conservation plans.
The goal of the Water Conservation Plan is to serve as good stewards of water
resources by preserving water supplies for essential uses and the protection of
public health. The objectives toachieve this goal are asfoLLovvs:
• To reduce the Loss and waste ufwater.
• To improve efficiency in both indoor and outdoor water use.
• Tn maximize the Level of recycling and reuse.
• To protect and preserve environmental resources.
• To extend the Life of current water supplies.
• To raise public awareness of water conservation and encourage responsible
personal behavior through public education programs.
, 1.01 MINIMUM REGULATORY REQUIREMENTS CHECKLIST
A water conservation plan is defined as "[a] strategy or combination of strategies for
reducing the volume of water withdrawn from a water supply source,for reducing the
Loss or waste of water,for maintaining or improving the efficiency in the use of water,
for increasing the recycling and reuse of water, and for preventing the pollution of
water. A water conservation plan may be a separate document identified as such or
may be contained within another water management docurnent' Recognizing the need
for efficient use of existing water supplies,the TCEQ has developed guidelines and
requirements governing the development of water conservation and drought
contingency plans.The minimum TCEQ requirements and where they are addressed
within this document are included in Appendix B.
1,02 ADDITIONAL REQUIREMENTS AND GUIDANCE
� In addition to TCEQ rules regarding water conservation,this Plan also incorporates
� both minimum requirements as required from NTMWD and elements from several
conservation initiatives.
� 2024NTMWD Water Conservation Plan— Member Cities and Customers of
� the NTMWD are required to implement water conservation strategies as
(
� designated in the NTk4VVD Water Conservation Plan.These strategies

2.00 WATER UTILITY PROFILE
This section contains a description of City of Wylie's service area and water system.This
information can also be reviewed in Appendix C, which contains a completed TCEQ Water
Utility Profile.
. 1 DESCRIPTION OF THE SERVICE AREA
The City of Wylie is a growing community which is a part of the Dallas-Fort Worth metroplex
and provides water to a retail service area of approximately 24.6 square miles and about
47,232 residents as of 2022 (NTMWD Member City and Customer Water Conservation
Report). Small portions within the City limits are served by other water providers.The City
purchases\treated water from North Texas Municipal Water District (NTMWD) through
parallel water supply lines throughout the city limits.The City is divided into two pressure
planes, referred to as the 730' Service Area and the 679' Service Area.These area names
correspond to the pressure plane elevations they serve.
2.02 WATERIL IL
City of Wylie's existing water supply is composed of the following sources.
Purchased Treated Water from NTMWD
3.00 WATER CONSERVATION GOALS
TCEQ rules require the adoption of specific 5-year and 10-year water conservation goals for a
water conservation plan.
. - AND 10-YEARGOALS
Per capita water use varies from year to year based on several factors including weather
conditions, changing demographics and other variables.The TWDB requires specific 5- and
10-year goals which are summarized in Table 1.These goals should be measured against a 5-
year average per capita, although some (dry) years will see higher per capita usage than these
5- year average goals. A series of dry years may lead to an average exceeding the goal.
It should be noted that the City's nonrevenue water percentage is significantly higher than its
water loss percentage.The basis for this difference is the high amount of unbilled unmetered
water that has been reported.The City has reported a five-year average of roughly
210,000,000 gallons per year of unbilled unmetered water versus a five-year average of
roughly 65,000,000 gallons per year of total water loss.The City has set procedures for
estimating usage related to line flushing, main breaks and other unbilled unmetered usage.

3.02 METHOD FOR TRACKING
NTMWD requires Member Cities and Customers to compLete annuaL conservation reports by
March 31 of the foLLowing year and submit them to NTMWD. A copy of the form is incLuded as
Appendix D.
The compLetion of this AnnuaL Water Conservation Report aLLows City of WyLie to track the
effectiveness of its water conservation programs over time and reassess those programs that
are not providing water savings, ensuring maximum water use efficiency and greater LeveLs of
conservation.
4~00 METERING, RECORDS AND WATER LOSS CONTROL
4.01 METERING PROGRAM
One of the key eLements in water conservation is carefuL tracking of water use and controL of
Losses. Carefui metering of water deUveries and water use, detection and repair ofLeaks in the
distribution systern, and reguiarnnonitoring of unaccounted water are important in cuntroiUng
Losses.
ACCURATE METERING OF TREATED WATER DELIVERIES FROM NTMWD
Accurate metering of water diversions and deLiveries, detectinn, and repair ofLeaks in the raw
water transmission and potabie water distribution systems and reguiar monitoring of
nonrevenue water are important eLements of NTMWD's program to controL Losses. Water
deLiveries from NTMWD are metered by NTMWD using meters with accuracy of±2%. These
meters are caLibrated on an annuaL basis by NTMWD to maintain the required accuracy.

METERING OF CUSTOMER AND PUBLIC USES
The provision of water to all customers, including public and governmental users, is metered in
the City of Wylie.
METER TESTING, REPAIR AND REPLACEMENT
The City of Wylie tests and replaces our customer meters on a regular basis. All residential
customer meters are budgeted to be replaced on a minimum of a 15-year cycle.
4.02 MONITORINGMANAGEMENT PROGRAM
As required by TAC Title 30, Chapter 288, a record management system should allow for the
separation of water sales and uses into residential, commercial, public/institutional, and
industrial categories.This information is included in the NTMWD annual water conservation
report that is included in Appendix D.
4.03 WATERLOSS CONTROL PROGRAM
DETERMINATION AND CONTROL OF WATER LOSS
Total water loss is the difference between treated water pumped and authorized consumption
or metered deliveries to customers. Authorized consumption includes billed metered uses,
unbilled metered uses, and unbilled unmetered uses such as firefighting and releases for
flushing of lines.
Water losses include two categories:
• Apparent losses such as inaccuracies in customer meters. (Customer meters tend to run
more slowly as they age and under-report actual use). Unauthorized consumption due
to illegal connections and theft.
• Real losses due to water main breaks and leaks in the water distribution system and
unreported losses.
LEAK DETECTION AND REPAIR
Measures to control water loss are a part of the routine operations of the City. Maintenance
crews and personnel look for and report evidence of leaks in the water distribution system.
Meter readers watch for and report signs of illegal connections so that they can be quickly
addressed. With the measures described in this Plan,the City should maintain a water loss
percentage below 3.6 percent in 2024 and subsequent years. Areas of the water distribution
system in which numerous leaks and line breaks occur are targeted for replacement funds as
funds are available.

S.00 CONTRACT REQUIREMENTS FOR WHOLESALE CUSTOMERS
Every water supply contract entered into or renewed after official adoption of this water
conservation plan, including any contract extension, will include a requirement that each
wholesale customer of City of Wylie must develop and implement a water conservation plan
and water conservation measures. If the customer intends to resell the water,then the contract
between the initial supplier and customer must specify that the contract for the resale of the
water must have water conservation requirements so that each successive customer in the
resale of the water will be required to implement water conservation measures in accordance
with the provisions of Title 30 TAC Chapter 388. Note: NTMWD refers to their drought
contingency plan (DCP) as the water resource and emergency management plan (WREMP)
and should be considered synonymous with a DCP.
RESERVOIR6.00
City of Wylie purchases treated water from NTMWD and does not have surface water
supplies for which to implement a reservoir system operations plan. NTMWD operates
multiple sources of water supply as a system.The operation of the reservoir system is
intended to optimize the use of the District's sources (within the constraints of existing water
rights) while minimizing energy use cost for pumping, maintaining water quality, minimizing
potential impacts on recreational users of the reservoirs and fish and wildlife.
7.00 CONSERVATION PLAN ADOPTION AND ENFORCEMENT
7.01 MEANS OF IMPLEMENTATION
Staff will implement the Plan in accordance with adoption of the Plan. Appendix G contains a
copy of the ordinance adopted regarding this Plan.The document designates responsible
officials to implement and enforce the Plan.
An ordinance adopted by the City Council on April 23, 2024 designating responsible officials
to implement and enforce the Water Conservation Plan can be found in Appendix G.The Plan
will be enforced by warning and penalties as follows:
• On the first violation customers will be given a written warning that they have violated
the mandatory water use restriction.
• On the second and subsequent violations citations may be issued to customers with
fines established by ordinance.
For violations of the Water Resource and Emergency Management Plan, enforcement is
outlined in Section 2.06 of that Plan.

7.02 REVIEWATE OF WATERCONSERVATION
TCEQ requires that the water conservation plan be updated every five years.This Plan will be
updated as required and as appropriate based on new or updated information.
7.03 REGIONAL WATER PLANNINGTNOTIFICATION
In accordance with TCEQ regulations, a copy of this water conservation plan was provided to
the Region C Water Planning Group. In accordance with NTMWD contractual requirements, a
copy of this water conservation plan was also sent to NTMWD.Appendix F includes a copy of
the letters sent.
8.00 WATER CONSERVATION PROGRAM
8.01 PUBLICE
A. NTMWD PUBLIC EDUCATION PROGRAM AND TECHNICAL ASSISTANCE
City of Wylie obtains water conservation support from the NTMWD.This includes several
public education and outreach efforts such as:
• Beginning in 2006 and continuing through 2018, NTMWD invested in the development
and implementation of the "Water IQ: Know Your Water" campaign, including
newspaper ads, radio spots, billboards, a website, and other forms of communication
all intended to educate the public regarding water use and water conservation. During
the 2017 campaign, over a quarter of a million people were reached by the program
through media relations, outreach and interactive media.The total audience reached
through the campaign in 2017 was over 88 million impressions.
In 2013, NTMWD participated in the "Water My Yard" program to install weather
stations throughout its service area to provide consumers with a weekly email or text
message and information through the Water My Yard website recommending the
adequate amount of supplemental water that is needed to maintain healthy grass in
specific locations.This service represents the largest network of weather stations
providing ET-based irrigation recommendations in the state of Texas and provides the
public with advanced information regarding outdoor irrigation needs,thereby reducing
water use.Through a series of selections on the type of irrigation system a consumer
has, a weekly email or text message is provided that will recommend how long (in
minutes) that an irrigation system needs to run based on the past seven days of
weather.This recommendation provides the actual amount of supplemental water that
is required for a healthy lawn based on research of the Texas A&M Agrilife Extension
Service and proven technologies.

Landscaping.
NTMWD aLso participates in a regionaL outreach campaign caLLed "Water is Awesome"
partnering with the City of DaLLas and Tarrant Regional.Water District. NTMWD Member Cities
and Customers have access to the campaign noateriais which inciude:
• In 2019, an additional.tagLine, "Keep Texas Water on Tap", was incorporated to
promote the Water is Awesome brand and direct traffic to waterisawesome.com.
• In 2030. a "customer city tomikit" provided custonnizabbe resources aiiovving cities to
incorporate their Logos with the campaign brand for their website, social. media, and
print. Cities are encouraged to use campaign resources to advance conservation efforts.
• In 2021.the regional.water providers coiiaborated to create the Regional,Landscape
Initiatives.This document was deveLoped as a resource of best management practices
for municipal.staff to heLp reduce water waste and encourage Long-term water
conservation in the North Texas region. Information consists of the background,
importance, and benefits of each BMP and key taLking points to consider when
impLementing the strategy. Several.of the optional.water management measures

Conservation materials and more are made available to Member Cities and Customers through
an online portal that is hosted by NTMWD. In addition to the portal the NTMWD actively
provides technical assistance through the following:
• NTMWD holds Regularly Scheduled Meetings with Member Cities and Customers for
water supply updates, public campaign strategies, and legislative activities related to
water and water conservation.
• NTMWD purchases American Water Works Association Research Foundation
Publications for use by Member Cities and Customers to further enhance resources for
water efficiency, water rate structures, etc. Additionally, NTMWD pays for Member City
and Customer membership to the Alliance for Water Efficiency.
• Since 2003, NTMWD has held Water Conservation Workshops for staff of its Member
Cities and Customers.These workshops have covered several conservation-related
topics, including TCEQ requirements for water conservation and drought contingency
plans, advanced water conservation strategies,current NTMWD water conservation
efforts, water conservation programs of the cities, current drought status, progress on
future water supplies, and related topics.These workshops also provide training and
education regarding water use accounting, irrigation evaluations, industrial, commercial,
and institutional audits, and other procedures. Additional examples include workshops
on Water Loss Audit Training as well as on the TWDB Water Conservation Planning
Tool.
• Based on the annual reporting data collected from Member Cities and Customers from
2022, approximately 24% of the District's treated water sales went to supply ICIM
users within their service area.To target programs for this customer base,the District
hired Plummer Associates, Inc.to create the Industrial, Commercial, Institutional and
Multifamily Program.The ICIM program provides NTMWD Member City and Customer
staff with the knowledge and tools necessary to identify ICIM customers with high
water usage.This program was created to categorize water use data to find outliers
and identify areas to concentrate water conservation efforts.This program can help
Member Cities and Customers' ICIM water customers develop targeted methods for
increasing water efficiency as an alternative to a traditional voluntary approach for
water consumption improvement.
• As part of the ICIM program,the District is currently engaging with the Member and
Customer Cities to encourage their ICIM customers to participate in Water Efficiency
Opportunity Surveys.These surveys encompass a building audit that recommends
various water conservation measures that can be implemented to save both money and
water. Items addressed include toilet retrofits, urinal retrofits, showerhead retrofits,
PAGE 9

8.02 REQUIRED CONSERVATION STRATEGIES
Thefniiovving water conservation strategies are required.These strategies represent minimum
measures to be innpiennented and enforced to promote water conservation and are to remain in
effect on a permanent basis.
A. TCEQ CONSERVATION PLAN REQUIREMENTS
The preceding sections cover the reguiatory requirements identified in TA[TitLe 30. Part 1,
Chapter 388, Subchapter B. Ruie 288.These ruies are incimded in Appendix B. '
B. CONSERVATION COORDINATOR
PAGE 10
2024 Water Conservation Plan
City of Wylie
The designation of a Conservation Coordinator is required by House Bill 1648, effective
September 1, 2017 for all retail public water utilities with 3,300 service connections or more.
The NTMWD requires that all Member Cities and Customers, regardless of number of
connections, appoint a Conservation Coordinator who will serve as the primary point of contact
between the entity and the District on conservation matters.
The duties of the Conservation Coordinator are as follows:
• Submit an annual conservation report to NTMWD by March 31.This is referred to as
the `Appendix D Report'. NTMWD will provide a blank workbook for each Member City
and Customer to fill out prior to the deadline.
• Submit an adopted water conservation and water resource and emergency
management plan by May 1, 2024 (and every five years afterwards).These plans must
be submitted to NTMWD,the applicable Regional Water Planning Group,TCEQ and
TWDB.The conservation coordinator is also responsible for submitting a copy of the
Plan if it is updated after initial adoption and submission.
Wylie's Conservation Coordinator is identified below. City of Wylie will notify NTMWD if this
changes at any point before the water conservation plan is updated.

D. ORDINANCES, PLUMBING CODES, OR RULES ON WATER-CONSERVING FIXTURES
City of Wylie's plumbing code standards encourages water conservation and meets the
minimum statutory requirements.The state has required water-conserving fixtures in new
construction and renovations since 1992.The state standards call for flows of no more than
2.5 gallons per minute (gpm) for faucets, 2.5 gpm for showerheads. As of January 1, 2014,the
PAGE 12
2024 Water Conservation Plan
City of Wylie
state requires maximum average flow rates of 1.28 gallons per flush (gpf) for toilets and 0.5
gpf for urinals. Similar standards are now required under federal law.These state and federal
standards assure that all new construction and renovations will use water-conserving fixtures.
E. REUSE AND RECYCLING OF WASTEWATER
NTMWD currently has the largest wastewater reuse program in the state. NTMWD has water
rights allowing reuse of up to 71,882 acre-feet per year (64 MGD) of treated wastewater
discharges from the Wilson Creek Wastewater Treatment Plant for municipal purposes.
Additionally, NTMWD has permitted and is currently constructing the Sister Grove Regional
Water Resource Recovery Facility (WRRF) in the Lavon Lake watershed.This facility will have
an initial capacity of 16 MGD and an ultimate capacity of 64 MGD.
NTMWD has also developed the East Fork Water Reuse Project which can divert treated
wastewater discharges by NTMWD and purchased wastewater return flows from TRA via
Main Stem Pump Station. NTMWD also provides treated effluent from its wastewater
treatment plants available for direct reuse for landscape irrigation and industrial use.
City of Wylie wastewater is treated by NTMWD at its Muddy Creek Wastewater Treatment
Plant.
F. YEAR-ROUND OUTDOOR WATERING SCHEDULES
A mandatory weekly watering schedule has been gradually gaining acceptance in the region
and the state. NTMWD requires all Member Cities and Customers to adhere to a permanent
outdoor watering schedule.
• Summer (April 1—October 31) —Spray irrigation with sprinklers or irrigation systems
at each service address must be limited to no more than two days per week.
Additionally, prohibit lawn irrigation watering from 10 a.m.to 6 p.m. Education should
be provided that irrigation should only be used when needed, which is often less than
twice per week, even in the heat of summer.
For residential water customers, watering days are defined as the assigned
trash/recycle pickup day for the property address associated with the irrigation system,
plus three days subsequent. If there is no street address associated with the property,
or there is more than one street address associated with a single contiguous property,
the watering days are Wednesday and Saturday. For industrial, commercial, and
institutional water customers, watering day is defined as Wednesday and Saturday.
• Winter (November 1— March 31) —Spray irrigation with sprinklers or irrigation
systems at each service address must be limited to no more than one day per week
with education that less than once per week (or not at all) is usually adequate.
PAGE 13
2024 Water Conservation Plan
City of Wylie
For residentiaL water customers, watering day is defined as the assigned trash/recycLe
pickup day for the property address associated with the irrigation system. If there is no `
street address associated with the property, or there is more than one street address
associated with a singLe contiguous property,the watering day is Wednesday. For
| industriaL, commerciaL, and institutionaL water customers, watering day is defined as
Wednesday.
AdditionaL irrigation may be provided by hand-heLd hose with shutoff nozzLe, use of dedicated
irrigation drip zones, and/or soaker hose provided no runoff occurs. Many North Texas
horticuLturists have endorsed twice-weekLy watering as more than sufficientfor Landscapes in
the region, even in the heat of summer. Citizens are encouraged to enroLL in the WeekLy
Watering Advice service offered by the Water Is Awesome campaign that is supported by
North Texas NunicipaiVVater District,Tarrant RegionaiWater District, and DaUas Water
UtiLities.This can be accessed at https:Hwaterisawesome.com/weekLy-wateri ng-advice.
G. TIME OF DAY WATERING SCHEDULE
. NTMVV[} requires that during the summer months (Aprii 1—October 31) under nnrnnai
conditions. spray irrigation with an irrigation system orsprinhierisonLv permitted on
/ '
' authorized watering days, before 10 a.m. or after 6 p.m.The primary purpose of this measure is
to reduce wind drift and evaporation Losses during the active growing season.The time-of-day
watering scheduLe requirement increases watering efficiency by eLiminating outdoor irrigation
use when cLimatic factors negativeLy impact irrigation system efficiencies. Midday irrigation is
not an optimaL time to irrigate because evapotranspiration rates are higher, and pLants are
more susceptibLe to stress associated with factors such as higher temperatures and Lower
reiative humidity.
H. IRRIGATION SYSTEM REQUIREMENTS FOR NEW AND COMMERCIAL SYSTEMS
In 2OO7.the 8OmTexas Legisiaturepassed House Biii 1658. 5enate Biii3. and House BiiL4
reLated to reguLating irrigation systems and irrigators by adopting minimum standards and
specifications for designing, instaLLing, and operating irrigation systems.The Texas LegisLation
required cities with a popuiation over I0.000todeve(op a Landscape irrigation program that
incLudes permitting, inspection, and enforcement of water conservation for new irrigation
systems.
NTMVVOnequires aLL Member Cities and Customers adhere to a minimum set of irrigation
standards:
1) Require that aLL new irrigation systems be in compLiance with state design and
instaKation reguiations (Texas Administrative CodeTitie 30. Chapter 344).
PAGE 14
2024 Water Conservation Plan
City of Wylie
2) Require operational rain and freeze sensors and/or ET or Smart controllers on all new
irrigation systems. Rain and freeze sensors and/or ET or Smart controllers must be
properly maintained to function properly.
3) Require that irrigation systems be inspected at the same time as initial backf Low
preventer inspection.
4) Require the owner of a regulated irrigation property to obtain an evaluation of any
permanently installed irrigation system on a 10-year basis.The irrigation evaluation
shall be conducted by a licensed irrigator in the state of Texas and be submitted to the
local water provider (i.e., city, water supply corporation).
I. WATER WASTEPROVISIONS
NTMWD requires all Member Cities and Customers prohibit activities that waste water.The
main purpose of a water waste ordinance is to provide for a means to enforce that water waste
is prevented during lawn and landscape irrigation,that water resources are conserved for their
most beneficial and vital uses, and that public health is protected. It provides a defined
enforcement mechanism for exceptional neglect related to the proper maintenance and
efficient use of water fixtures, pipes, and irrigation systems.The ordinance can provide
additional assistance or enforcement actions if no corrective action has been taken after a
certain number of correspondences.
NTMWD requires that the following water waste ordinance offenses include:
1) The use of irrigation systems that water impervious surfaces. (Wind-driven water drift
will be taken into consideration.)
2) Outdoor watering during precipitation or freeze events.
3) The use of poorly maintained sprinkler systems that waste water.
4) Excess water runoff or other obvious waste.
5) Overseeding, sodding, sprigging, broadcasting or plugging with cool season grasses or
watering cool season grasses, except for golf courses and athletic fields.
6) The use of potable water to fill or refill residential, amenity, and any other natural or
manmade ponds. A pond is considered to be a still body of water with a surface area of
500 square feet or more.This does not include recreational swimming pools.
7) Non-commercial car washing that does not use a water hose with an automatic shut-
off valve.
PAGE 15
2024 Water Conservation Plan
City of Wylie
8) Hotels and motels that do not offer a linen reuse water conservation option to
customers.
9) Restaurants, bars, and other commercial food or beverage establishments that provide
drinking water to customers unless a specific request is made by the customer for
drinking water.
8.03 POTENTIAL FUTURE STRATEGIES
A. USE OFET-BASED WEEKLY WATERING ADVICE/RECOMMENDATIONS
NTMWD requires that Member Cities and Customers adhere to a year-round outdoor watering
schedule. However,this conservation practice can be improved with the use of ET-based
weekly watering advice and recommendations. Landscapes frequently require less watering
than the year-round water schedule allows.This measure can be particularly useful for entities
with a significant percentage of customers using automated landscape irrigation systems.
Water providers in the Dallas-Fort Worth area (including NTMWD) sponsor weather stations
to collect daily weather data and provide the most accurate watering recommendations. Many
cities in the DFW area can already take advantage of these ET-based recommendations and
incorporate them into their water conservation programs, at no cost to the city. Examples of
such a service are shown below.
• Water My Yard—An online platform where homeowners can sign up to receive weekly
watering recommendations based on their location and a few specifications about their
sprinkler system. Users can then choose to accept the recommendations by email,text,
or both. Recommendations are available for select cities in Collin, Dallas, Denton,
Fannin, Hunt, Kaufman and Rockwall Counties. Sponsored by NTMWD and Texas A&M
Agri Life Extension Service. (WaterMyYard.org).
• Water Is Awesome Weekly Watering Advice—Weekly watering recommendations
for most of North Texas based on data from weather stations scattered throughout the
DFW area.The recommendations are distributed by email and text every week and are
provided in inches of water needed and the number of minutes necessary to apply that
amount of water for spray, rotor, and multi-stream sprinklers. Advice service is
available for all of North Central Texas and sponsored by DWU and TRWD.
(https://waterisawesome.com/weekly-watering-advice).
• WaterWise Newsletter and Hotline—The City of Frisco provides weekly lawn
watering advice on the city's website and through the WaterWise Newsletter
distributed to subscribers every Monday. Frisco also has a "Weekly Watering Advice
PAGE 16
2024 Water Conservation Plan
City of Wylie
Hotline"you can into weekly to get this information. Frisco has a weather station that is
used to determine how much water is needed each particular week.
Providing evapotranspiration (ET)-based weekly watering recommendations can reduce the
amount of water applied for outdoor watering if customers follow the guidance. A drawback
with this BMP is the adoption rate. Since these recommendations may change every week, it
requires customers to adjust their controllers more often.
It is important to note that at a minimum, Member Cities and Customers must adhere to the
year-round outdoor watering schedule set by NTMWD.
WATERB. EFFICIENT L.ANDSCAPE INITIATIVES
NTMWD recommends that Member Cities and Customers include water efficient landscape
initiatives in their water conservation plans. A water efficient landscape is a landscape that is
designed and maintained according to basic good horticultural principles that allow for a
beautiful healthy landscape with minimal or no supplemental irrigation and no adverse runoff
from the landscape property. Water efficient landscapes limit or exclude non-functional turf
where possible. Examples of nonfunctional turf include streetscape turf and turf that is purely
ornamental. As an alternative to non-functional turf grasses, water efficient landscapes use
appropriate plants or other landscaping materials that require little or no supplemental
irrigation. Appropriate plants are those selected based on their adaptability to the region's soil
and climate. NTMWD's#PledgeT®PLantSmart initiative seeks to inspire positive change in
water conservation by encouraging North Texas residents to do their part and plant smart by
selecting native or adaptive plants for their garden and landscaping. Member Cities and
Customers should adopt a native and adaptive recommended plant list for water efficient
Landscaping. Water efficient landscapes can be an alternative to non-functional turf grasses
and may be appropriate for application in new development or retrofits of existing landscapes
for both commercial and residential areas.
Water efficient landscape initiatives can be encouraged through financial incentives or required
through ordinance. Member cities and customers should also consider review of their existing
requirements and removal of current codes that may impede or limit the application of water
efficient landscapes. Property code 202.007 may be a helpful resource for language for
removing potential barriers to water efficient landscapes.
In lieu of an ordinance, water efficient landscapes can be encouraged through rebates for
Landscape conversion or installation or award programs. Good examples of water efficient
Landscapes should also be encouraged through public outreach, demonstration gardens,
and/or used in public landscapes and rights-of-way. NTMWD has a great example of the
implementation of native plants and xeriscaping at the Bois d'Arc Lake Operations Center.
PAGE 17
2024 Water Conservation Plan
City of Wylie
There are several programs available that offer a wealth of information on designing and
implementing water efficient landscape.
• Water Wise (http://urbanLandscapeguide.tamu.edu/waterwise.htmL)
• Texas SmartScapeT"'(ht gj/www txsmartsca e.co )
• EARTH-KIND TN1(htt S://a ie-hortic ltu e.tamu,e � earthki d ublications/ waater)
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans.
C. ADDITIONAL WATER SAVING MEASURES FOR NEW IRRIGATION YT
REQUIREMENTS
NTMWD requires certain irrigation system requirements for new and commercial systems.
However,this conservation practice can be improved with additional water savings measures.
As discussed previously,the Texas legislation regulates irrigation systems and irrigators by
adopting minimum standards and specifications for designing, installing, and operating
irrigation systems.
Many cities within Region C have adopted irrigation system standards above the minimum
state requirements. Some of these standards include:
• Require property owners who install their irrigation system to also comply with the
adopted city ordinance.
• Require submission of the irrigation plan in conjunction with the permit application to
the applicable city officiaUdepartment.
• Require all new irrigation systems to not utilize above-ground spray in landscapes that
are less than 60 inches in either length or width and which contain impervious
pedestrian or vehicular traffic surfaces along two or more perimeters.The use of
subsurface or drip irrigation and pressure compensating tubing is permitted if the
qualifying area will be irrigated.
• Require all non-turf landscape areas included in the irrigation plan to be designed with
subsurface irrigation, drip irrigation, and/or pressure compensating tubing. If the
irrigation plan includes a foundation watering system, require a separate zone to be
dedicated for drip irrigation for the purpose of watering a structure's foundation.
• Require a flow control master valve to be installed on the discharge side of the
backflow prevention device on all new installations.
PAGE 1
2024 Water Conservation Plan
City of Wylie
• Require check valves where elevation differences may result in low head drainage.
Check valves may be located at the sprinkler heads) or on the lateral line.
• Require that pop-up heads shall be installed at grade level and operated to extend
above all landscape turfgrass.
• Require that all new irrigation systems must include an automatic controller capable of
providing the following features:
o Multiple irrigation programs with at least three start times per program
o Limiting the irrigation frequency to once every 7 days and once every 14 days
o Water budgeting feature
• Require additional information and description for the required "walk-through".This
may include but is not limited to a checklist of things to cover on the "walk-through"
with the homeowner or educational leave behind materials.
• Require the signed maintenance checklist be submitted to the applicable city
official/department. Require the irrigator's name, license number, company name,
telephone number, and the dates of the warranty period to be on the maintenance
checklist.
• Require the irrigation plan indicating the actual installation of the system and the
associated seasonal watering schedule be submitted to the applicable city
officiaUdepartment.
• Require the irrigation plan and maintenance checklist be transferred from the new
home builder to the first home buyer with documentation confirming the transaction
provided to the applicable city official/department.
It is important to note that, at a minimum, Member Cities and Customers must adhere to
the irrigation system requirements set by NTD.
D. ADDITIONAL WATER WASTEPROVISIONS
NTMWD requires certain water waste provisions. However,this conservation practice can be
improved with the inclusion of additional water waste provisions suited for your entity. As
discussed previously,the main purpose of a water waste ordinance is to provide a means for
enforcement that water waste is prevented during lawn and landscape irrigation,that water
resources are conserved for their most beneficial and vital uses, and that public health is
protected. It provides a defined enforcement mechanism for exceptional neglect related to the
proper maintenance and efficient use of water fixtures, pipes, and irrigation systems.The

E. PARK/ATHLETIC FIELD CONSERVATION
NTMWD recommends that Member Cities and Customers consider the impLementation of this
conservation practice if there are parks and/or athLetic f ieLds within their system that are heavy
water users.This conservation practice is intended to address park and athieticfieid
conservation if the water provider manages and/or serves customers with irrigated parks
PAGE20
2024 Water Conservation Plan
City of Wylie
and/or athletic fields.These facilities often face scrutiny by the public for using large amounts
of water or being perceived as using excessive amounts.Athletic field and park irrigation
conservation practices and the careful use of water in the operation and maintenance of park
facilities can effectively reduce water demands. Once a water provider or customer adopts this
practice, it should be followed closely to achieve maximum water efficiency benefits. With the
dedication of an athletic field manager, athletic field conservation can effectively reduce
system water demand. A manager can implement a watering regimen that only uses the
amount of water necessary to maintain the viability of the turf and health of its users.
All park facilities should be metered, and water use billed to reinforce the importance of water
efficiency. Before developing an efficient watering program,the water provider should
consider meeting with parks irrigation personnel, management, and authorized landscape
manager.This discussion should focus on water conservation issues and developing an
adequate scope of action for efficiency.The first key is to understand the performance and
capabilities of your irrigation system at these facilities. Requiring automatic irrigation systems
and controllers at all facilities is recommended. It is essential to have training in soil
management, proper aeration methods, nutrient management, mowing, soil testing, and
irrigation management.
Achieving conservation can be voluntary or regulatory, based on the needs of the city. Cities
may also consider if there is an opportunity to use reclaimed, reused, or recycled water for
parks to conserve potable water. However, specific uses must meet TCEQ water quality
standards for reclaimed water and human contact, and they must be appropriate for the
particular use of the park. Reclaimed water should be applied based on the appropriate water
budget. When developing athletic field conservation practices, identify the various
stakeholders, including the school district staff, nonprofit athletic associations, private sports
complex managers, and city staff. Meeting with them will help achieve long-term results.
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans.
F. GOLF COURSE CONSERVATION AND REUSE
NTMWD recommends that Member Cities and Customers consider the implementation of this
conservation practice if there are golf courses within their system that are heavy water users.
Golf courses can use a considerable amount of water for irrigation, especially during the
summer.The Environmental Institute for Golf found that from 2003-2005, an 18-hole course
in the southeast region of the country (including North Central Texas) applied an average of 29
inches of irrigation water per acre every year. Irrigation of course play areas, such as fairways,
is necessary to support healthy turfgrass and landscape plants, which are important for course
playability and aesthetics. However, golf courses can employ several practices to reduce water

/
use whiLe maintaining the course's pLayabiLity and aesthetics. ALso, overwatering and over-
fertiLization can negativeLy impact the water quaLity in Local.streams and Lakes. �
� By adopting a conservation pian. goLf courses can benefit by:
• Being a good neighbor by conserving iocai water suppUes
• Saving money by reducing water use
• Protecting iocai water quaUty
• Maintaining piaying conditions on the course
• Increasing irrigation equipment Longevity
Water providers may take different goLf course conservation approaches: encouraging
voLuntary efforts by the goLf courses to conserve water, making it required as part of a contract,
or, if possibLe, passing an ordinance requiring goLf courses to deveLop and impLement a
conservation pLan. It is important for water providers to work cLoseLy with goLf courses since
they know which practices wiLL have the greatest potentiaL for impLementation.The courses
may have aLready compLeted some best management practices and knowLedge which may be
effective or not. Water providers shouLd work to coordinate and impLement conservation
practices on courses that are owned and operated by the LocaL government.
Water conservation and water quaLity protection measures for goLf courses may incLude, but
are not Limited to,the foiiovving:
Golf Course Landq."a @ Design and Water Sources
• When feasibLe, use afternative water sources, such as recLaimed or reuse water from

G. USE OF LICENSED IRRIGATORS TO INSPECT AND REVIEW ALL IRRIGATION PERMITS
AND PLANS
Another potentiaiconservation practice to irnpiernentisthe requirement of Licensed irrigation
inspectors to review and inspect aLL irrigation system pLans and instaLLed components before a
permit is reLeased. Many cities use Licensed pLumbing inspectors, as aLLowed by TCEQ ruLes,to
perform these duties. However, having dedicated Licensed irrigation inspectors to impLement
aLL aspects of an irrigation system permitting program provides a certain LeveL of focus for
compiving with water efficiency standards. Reviewing irrigation permits and pians before
instaLLing aLLows for changes to be made to the pLans and not after the pipe is aLready in the
� ground.This ensures the irrigation system's overaLL quaLity, promotes irrigation efficiency and
guarantees that the system wiLL compLy with state and LocaL requirements.
DeveLoping a review and inspection program at the municipaL LeveL reduces the chance for
unUcensed irrigators to instaii irrigation systems innproperLv. Improper instaLiation can waste
water, money, cause future maintenance issues, but most importantLy, it may contaminate the
pubLic water suppLy. It is cruciaL to prevent non-potabLe water in Lawn irrigation pipes from
flowing into pubiic water supp[y pipes.
| Inspecting the system provides benefits for water conservation. With open-trench inspections,
you can check:
• Depth of piping-which protects from freezing temperatures
•' Potentiai invasion ofpiant/shrubbery roots
| • Joints are giuedappropriatek/. and no Leaks occur
�
• Pipe size-to eUnninate water hammer
• Pressure management requirements
• The overa[i Layout of the system
Staff can hoLd an irrigator's License and inspector's License, but to prevent them from instaLLing
and inspecting their work, staff can't have both running concurrentLy. In 2011, the 82 n'Texas
Legisiature passed House Biii 2507. making it a Ciass [ misdemeanor for an individuaitn
operate as an irrigator in the state of Texas without a vaLid irrigation License.Therefore,
effective September l. 3011. individuaLs operating without License are in directvioLatiun of
the Texas Occupationai[ode. Sec. 1903.250.

According to the Texas Administrative Code, upon completion of the irrigation system,four
items must be completed to inform and educate the owner of the system: a final walk-through,
a maintenance checklist, licensed irrigator contact information, and an as-built plan. All
irrigation system plans, installation, and review requirements must be followed for long-term
water efficiency. Minimum state requirements for Landscape Irrigation can be found in Chapter
344 of the Texas Administrative Code.
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans.
H. OFFER FREE OR DISCOUNTED IRRIGATION SYSTEM CHECK-UPS FOR RESIDENTIAL
CUSTOMERS
The EPA estimates that up to 70% of the total water used during the summer months is
applied as outdoor irrigation. As much as 50% of the water used outdoors is wasted due to
overwatering and inefficient or malfunctioning irrigation system components. Irrigation system
check-ups (also known as evaluations or audits) for residential customers, is a tool that cities
can employ to reduce outdoor watering demand. Check-ups are typically offered at no charge
to homeowners. A licensed irrigator will evaluate the irrigation system components and
controller settings during a typical check-up to see if the irrigation system can operate more
efficiently and identify needed repairs or adjustments.The licensed irrigator will run the
irrigation system to see if the sprinkler heads function correctly and apply water only to the
intended areas.They will check the irrigation system's pressure and discuss the controller
settings with the homeowner to advise them on the most efficient watering methods.
One valuable aspect of check-ups is the one-on-one assistance and education that a
residential customer receives on properly managing the irrigation system.This education can
result in long-term water savings because the customer has a better understanding of the
system. Water savings may last for multiple years after the evaluation is completed, mainly
due to more efficient watering habits. As part of the check-up,the licensed irrigator will
identify inefficiencies in the resident's irrigation system and educate them on programming the
irrigation controller for more efficient watering practices, such as seasonal adjustment settings
and 'Cycle and Soak'.The sponsoring water provider or city can also offer handouts, brochures,
and other educational information to residents.The licensed irrigator can provide a report to
the residential customer detailing equipment problems and offer recommendations to change
watering habits. Reports can include an estimated water savings amount based on
recommended adjustments to the controller's run times.The licensed irrigator should also
provide a copy of the report to the sponsoring water provider or city.
Benefits of check-ups include one-on-one contact with residential customers, providing
educational information that may result in greater water savings than irrigation system fixes

aLone. Check-ups are an exceLLent customer service tooL when managing residents' compLaints.
When using check'ups, cities can be seiecdve by targeting high water users or those with
| Large Lots to maximize budget and water savings. Water providers or cities shouLd consider
conducting a customer satisfaction survey after the check-up is compLeted to determine how
many residents have impLemented recommended modifications and gauge satisfaction with
the check-up program.
N7-MWDmemonnrnends but does not require inmpbennentationmf this conservation practice in
Member Cities and Customers' own water conserwationpLans'
0' REBATES
NTMWD recommends that Member Cities and Customers consider offering a rebate program
as a conservation practice to be incLuded as part of their water conservation pLan. As the
popuLation increases in the North Texas region,the demand for water grows, especiaLLy
because many newer cities require irrigation systems in new deveLopments.
�
' Creating a program that encourages residents to become educated on their irrigation system
| can improve operation and efficiency. Furthermore, when it comes to the type of irrigation
|
system and standard efficiencies,the Texas AgriLife Research and Extension Urban SoLutions
Center provides the foiiovving average efficiencies by system type:
• Surface/Subsurface drip—9O96
• Su/face micro drip irrigation—8596
• Large Rotors—7O96
• Smaii Rotors—6596
IF Spray Heads— 5O96
This conservation practice ofa rebate program provides, in conjunction with a sprinkier
evaLuation (check-up) program, an incentive to have an evaLuation done and make
recommended changes. With such a substantiaL opportunity for efficiency gains, some entities
may wish to consider offering rebates to both residentiaiand connrnenciai customers for
upgrading their current irrigation systems. By changing out Less efficient equipment,this
conservation practice intends to increase the irrigation efficiency by 10% or more. With 31% of
aiiresidentiai water use statewide attributed to irrigation, and most of that conducted using
spray heads with an average efficiency of 50%,there is a reaL benefit for cleveLoping a rebate
program for irrigation systems.
ALthough rebates for irrigation systems can have Large impacts,there are aLso severaL other
water conservation incentive programs that can be impLemented. Other exampLes incLucle:
PAGE26

City of Wylie
•, Commercial clothes washer rebates for the purchase and installation of high efficiency
card- or coin-operated commercial clothes washers
• Low-flow toilet replacement and rebate programs
• Rebates for rain/freeze sensors and/or ET or Smart controllers
• Low-flow showerhead and sink aerators replacement programs or rebates
• Residential water efficient clothes washer rebates
• Pressure reducing valve installation programs or rebates
• Rain barrel rebates
• Pool cover rebates
• On-demand hot water heater rebates
• Other water conservation incentive programs
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans.
J. ICIM RECOMMENDATIONS
NTMWD has partnered with Plummer Associates, Inc.to develop the ICIM program to identify
where additional ICIM water savings can be achieved. Member Cities and Customers can adopt
a similar approach by implementing the following conservation practices:
• Classification of Customers by Specific End Use - A billing system that identifies
customers by criteria specific enough to assess usage patterns can greatly assist in
reviewing drivers of demand and developing targeted conservation efforts. For
example, rather than identify customers as residential, commercial, industrial, or
institutional, which is very broad, utilities can classify customers by specific end uses
such as Veterinary Hospitals, Full-Service Hotels, or Day Care Centers.
• End Use Analysis - In order to determine what water conservation and efficiency
programs and policies will be most effective in managing demand, a water utility needs
to understand the makeup of its customer base and conduct a thorough assessment of
end use water efficiency measures. Understanding what technologies are available,
understanding how far along end users are in adopting these new technologies, and
understanding the potential impacts to long-term water use trends, allow planners to
target the most effective drivers of change.
PAGE 27
2024 Water Conservation Plan
City of Wylie
• Benchmarking - As businesses grow,they tend to add more customers and
productions. As such, it can be difficult to see the benefit of targeted conservation
efforts if you are only looking at the total annual water use. Development of effective
and meaningful Benchmarking, such as gallons per pound of product, gallons per guest
per day, gallons per meal, etc., allows end users to gauge their effectiveness in using
water and energy efficiently by providing measures that are easy to define and allow
for comparison amongst piers. Additionally, benchmarking allows end users to gauge
the effectiveness of their efforts year over year.
v Providing Water Efficiency Opportunity Surveys for ICIM Customers - A detailed
water efficiency survey can enable end users to understand how they use water,
develop a complete inventory of water using equipment and processes, identify
potential leaks and losses, set realistic reduction goals, identify and implement useful
policies, identify low cost/no cost projects and assess potential investments in
significant projects aimed at reducing long-term water demand. Members can reach out
to NTMWD to participate in the ongoing Water Efficiency Opportunity Surveys.
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans. NTMWD recommends that
all Member Cities and Customers participate in the ICIM program and takes advantage of
the Water Efficiency Opportunity Surveys.
K. WATER EFFICIENCY OUTREACH PROGRAM
NTMWD provides a wealth of technical assistance and outreach. Wholesale and retail water
providers benefit from a consistent water conservation message across multiple cities and can
enhance their reputation in the community. Utilizing resources and programs from NTMWD's
conservation portal allows Member Cities and Customers to save money by not producing the
resources or operating the programs themselves and amplifies a common message. Outreach
assistance from NTMWD accomplishes public outreach and education elements in both the
wholesale and retail water providers respective water conservation plans.
However, it is recommended that each member city and customer develop their own water
efficiency outreach program as well. Perhaps one of the most important actions a utility can
take in increasing water use efficiency among its customers is through public education and
outreach programs (E&O).The goal of E&O programs is to influence behavioral change for
short and long-term water savings. Regular and consistent messaging in customer education
will provide an overall picture of water resources in the community. Communicating the need
for conservation helps manage existing water supplies and avoids or delays the need for
expanded or new infrastructure to meet increased water demands. Customer education also
provides valuable information on specific actions they can take in their home or business to
PAGE 2
2024 Water Conservation Plan
City of Wylie
meet these community goals while also benefiting from them personally (i.e., managing their
water bill).
Each utility should develop an education and outreach plan suited to their community that is
adaptable over time. Understanding which messages need to be conveyed regularly and
identifying the target audience(s) is key to a successful program. An effective public education
program will help develop trust between the community and the utility as relevant,timely, and
fact-based information is provided, and customer service is enhanced.
Many cities have dedicated water conservation web pages located within the main city or
utility website that provide tips and other resources.The TWDB is one source that provides
publications and other materials that can be placed online or made available in city/utility
buildings. NTMWD's online conservation portal is another.The various education and outreach
tools also allow cities to promote other programs offered, such as rebates or events, and to
communicate other important messages, such as drought conditions or water service outages.
Some customers prefer to learn in a classroom setting or to tour facilities or demonstration
areas to better understand certain conservation techniques. Offering in-person or virtual
classes or workshops provides an opportunity to connect with these customers, provides
hands-on experience, and allows questions on a range of conservation issues to be answered..
NTMWD offers several programs such as these described in Section 8.02.
NTMWD recommends but does not require implementation of this conservation practice in
Member Cities and Customers' own water conservation plans.

Under Texas Water Code Chapter 11 and Title 30 Texas Administrative Code Chapter 288,
Retail, Irrigation and Wholesale Public Water Suppliers are required to develop, implement
and submit updated Drought Contingency Plans to the TCEQ every five years.
2024 Water Resource and Emergency Management Plan
City of Wylie
INTRODUCTION1.00
City of Wylie is a Member City of the North Texas Municipal Water District (NTMWD).This
Plan was developed following TCEQ guidelines and requirements governing the development
of drought contingency plans.
The goal of the water resource and emergency management plan is to prepare for potential
water shortages and to preserve water for essential uses and the protection of public
health.The objectives to achieve this goal are as follows:
• To save water during droughts, water shortages, and emergencies.
• To save water for domestic use, sanitation, and fire protection.
• To protect and preserve public health, welfare, and safety.
• To reduce the adverse impacts of shortages.
• To reduce the adverse impacts of emergency water supply conditions.
Note: NTMWD refers to their drought contingency plan (DCP) as the water resource and
emergency management plan (WREMP) and should be considered synonymous with a DCP.
. 1 MINIMUM REGULATORY REQUIREMENTS
A drought contingency plan is defined as "a strategy or combination of strategies for
temporary supply and demand management responses to temporary and potentially recurring
water supply shortages and other water supply emergencies". Recognizing the need for
efficient use of existing water supplies,the TCEQ has developed guidelines and requirements
governing the development of water conservation and drought contingency plans.
The minimum TCEQ requirements and where they are addressed within this document are
described in Appendix B.

As required by TCEQ ruLes, City of WyLie must review their respective PLan every five years,
The pLan wiLL be updated as appropriate based on new or updated information.
3~00'WATER RESOURCE AND EMERGENCY MANAGEMENT PLAN
Initiation and termination criteria for water manageiihent stages incLude generaL, demand,
suppLy. and emergency criteria. One of the major indicatnrsofapproachingurongoingdrnught
conditions is NTMWD's combined reservoir storage, defined as storage at Lavon Lake pLus
storage in Bois d'Arc Lake. Percent storage is determined by dividing the current storage by
the totai conservation storage when the Lakes are fuiLTable 2 summarizes the water
management stages by triggers based on percent combined storage and associated demand

reduction goals and outdoor watering restrictions.The following sections go into more detail
on the three water management stages.
TCEQ requires notification when mandatory restrictions are placed on a customer. NTMWD
must notify TCEQ when they impose mandatory restrictions on Member Cities and Customers.
Member Cities and Customers must likewise notify TCEQ when they impose mandatory
restrictions on their customers (wholesale or retail). Measures that impose mandatory
requirements on customers are denoted with "requires notification to TCEQ". NTMWD and
the utilities must notify TCEQ within five business days if these measures are implemented
