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 to achieve this goal are as follows: ■ To reduce the loss and waste of water. • To improve efficiency in both indoor and outdoor water use. • To 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A water conservation plan is defined as "[a] strategy or combination of strategies for reducing the volume of water withdrawn from a water supply source, for reducing the loss or waste of water, for maintaining or improving the efficiency in the use of water, for increasing the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 document". Recognizing the need for efficient use of existing water supplies, 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. • 2024 NTMWD Water Conservation Plan — Member Cities and Customers of the NTMWD are required to implement water conservation strategies as designated in the NTMWD Water Conservation Plan. These strategies represent minimum measures to be implemented and enforced to promote water conservation and are to remain in effect on a permanent basis. 4 2024 Water Conservation Plan Town of Prosper Guidance and Methodology for Reporting on Water Conservation and Water Use - Developed by TWDB and TCEQ in consultation with the Water Conservation Advisory Council (the Guidance). The Guidance was developed in response to a charge by the 82"d Texas Legislature to develop water use and calculation methodology and guidance for preparation of water use reports and water conservation plans in accordance with TCEQ rules. North Texas Regional Landscape Initiative — The North Texas regional water providers (NTMWD, DWU and TRWD) collaborated 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 included in this Plan are from this collaborative initiative. 2.00 WATER UTILITY PROFILE This section contains a description of Town of Prosper's service area and water system. This information can also be reviewed in Appendix C, which contains a completed TCEQ Water Utility Profile. 2.01 DESCRIPTION OF THE SERVICE AREA Town of Prosper serves a 25.6 sq mi area with a population of 38,840. The Town of Prosper is a fast-growing community with a projected buildout population of 72,000. 2.02 WATER UTILITY PROFILE The Town of Prosper's existing water supply is composed of the following sources. a 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. 3.01 5- AND 10- YEAR GOALS 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. 5 2024 Water Conservation Plan Town of Prosper Table 1: Five- and 10-Year Per Capita Water Use Goals Historicseline • 1 • Year ' �� 2029 2034 Total (GPCD)' 222 231 223 218 148 138 134 Residential 138 (GPCD)2 ICIM_(GPCD 3 21 22 22 23* Water Loss 5 12 10 11 (GPCD)4 2% _ 5% Water Loss _(Percentage s 4.8% 5.3%* 'Total GPCD = (Total Gallons in System/Permanent Population/365 2 Residential GPCD = (Gallons Used for Residential Use / Residential Population) / 365 3 ICIM GPCD = (Gallons Used for Industrial, Commercial, Institutional and Multi -family Use /Permanent Population) / 365 4 Water Loss GPCD = (Total Water Loss / Permanent Population) / 365 5 Water Loss Percentage = (Total Water Loss / Total Gallons in System) x 100, or (Water Loss GPCD / Total GPCD) x 100 *10-Years goals reflect Prosper's fast-growing community with anticipated new businesses and a projected buildout population of 72, 000. 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 Town of Prosper 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. Careful metering of water deliveries and water use, detection, and repair of leaks in the distribution system, and regular monitoring of unaccounted water are important in controlling losses. ACCURATE METERING OF TREATED WATER DELIVERIES FROM NTMWD Accurate metering of water diversions and deliveries, detection, and repair of leaks in the raw water transmission and potable water distribution systems and regular 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. 1.1 2024 Water Conservation Plan Town of Prosper METERING OF CUSTOMER AND PUBLIC USES Town of Proser uses Neptune meters that are electronically metered through AclaraONE. METER TESTING, REPAIR AND REPLACEMENT The Town of Prosper plans to test 1 % of meters that are older than 10 years and replace as needed. Meters are also tested and replaced as needed by request or when issues arise. 4.02 MONITORING AND RECORD MANAGEMENT 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 WATER LOSS 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 Water utility crews, building inspectors, and personnel will look for and report evidence of leaks in the water distribution system. Water usage is tracked using advanced metering infrastructure to collect data and is monitored closely by our Utility Billing Department. Areas of the water distribution system, in which numerous leaks and line breaks occur, will be targeted for replacement, as funds are available. 7 2024 Water Conservation Plan Town of Prosper 5.00 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 Town of Prosper 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 288. 6.00 RESERVOIR SYSTEM OPERATIONS PLAN The Town of Prosper 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 AND ENFORCEMENT Staff will implement the Plan in accordance with adoption of the Plan. Appendix F contains a copy of the ordinance adopted regarding this Plan. The document designates responsible officials to implement and enforce the Plan.

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. 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. 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 sufficient for landscapes in the region, even in the heat of summer. The Town of Prosper has a year-round permitted watering day schedule based on location zones. 12 2024 Water Conservation Plan Town of Prosper LEGEND I ZONE 1 � ZONE 2 9� ZONE 3 IIM. ZONE 1 MONDAY URSDAY ZONE 2 R DA AY W FIF ZONE 3 N(6) AIURDAY NFSDAY ZONE 1 ZONE 2 ZONE 3 MONDAY 6 'N!-I1Nh 5DAY FRIDAY �6 G. TIME OF DAY WATERING SCHEDULE NTMWD requires that during the summer months (April 1 — October 31) under normal conditions, spray irrigation with an irrigation system or sprinkler is only 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 relative humidity. H. IRRIGATION SYSTEM REQUIREMENTS FOR NEW AND COMMERICAL SYSTEMS In 2007, the 80th Texas Legislature passed House Bill 1656, Senate Bill 3, and House Bill 4 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 population over 20,000 to develop a landscape irrigation program that includes permitting, inspection, and enforcement of water conservation for new irrigation systems. NTMWD requires all Member Cities and Customers adhere to a minimum set of irrigation standards: 13 2024 Water Conservation Plan Town of Prosper 1) Require that all new irrigation systems be in compliance with state design and installation regulations (Texas Administrative Code Title 30, Chapter 344). 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 backflow preventer inspection. 4) Require the owner of a regulated irrigation property to obtain an evaluation of any permanently installed irrigation system on a 3-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 WASTE PROVISIONS 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. 14 2024 Water Conservation Plan Town of Prosper 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. As per Town of Prosper ordinance, 011-- ) # enforcement of the offenses stated in the Water Conservation Plan will be through administrative fees. 8.03 ADDITIONAL CONSERVATION STRATEGIES A. USE OF ET -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 (DFW) 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 AgriLife 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 (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 Hotline" you can into weekly to get this 15 2024 Water Conservation Plan Town of Prosper 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. B. ADDITIONAL WATER WASTE PROVISIONS 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 ordinance can provide additional assistance or enforcement actions if no corrective action has been taken after a certain number of correspondences. 1) Sprinkler runoff from a property greater than 50 feet. 2) Operating an irrigation system or other lawn watering device during any form of precipitation or when temperatures are below 32 degrees Fahrenheit. 3) Failure to repair a controllable leak, including but not limited to a broken sprinkler head, a leaking valve, leaking or broken pipes, or a leaking faucet. 4) Operating a permanently installed irrigation system with a broken head or a head that is out of adjustment where the arc of the spray head is over a street or parking lot. 5) Washing of driveways, sidewalks, parking lots or other impervious surface areas with an open hose or spray nozzle attached to an open hose, except when required to eliminate conditions that threaten public health, safety or welfare. C. OFFER FREE OR DISCOUNTED IRRIGATION SYSTEM CHECK-UPS FOR RESIDENTIAL CUSTOMERS. The Town of Prosper offers free sprinkler inspections through the Sprinkler Evaluation Program. Residents can submit requests through the MyProsper App for a free sprinkler checkup provided by a licensed irrigator with the Town of Prosper. The licensed irrigator will evaluate the irrigation system components and controller settings during the checkup to see if the irrigation system can operate more efficiently and identify needed repairs or adjustments. They will run the irrigation system to see if the sprinkler heads function correctly and apply water only to the intended areas. The licensed irrigator will check and discuss the controller settings with the homeowner to advise them on the most efficient watering methods. Through this one-on-one assistance, the licensed irrigator will educate the resident irp 2024 Water Conservation Plan Town of Prosper on efficient watering practices and promote seasonal adjustment settings and the "Cycle and Soak' method. Educational informational handouts are also provided to residents during the visit. After the evaluation, the licensed irrigator will provide a report to the residential customer detailing equipment problems and offer recommendations to change watering habits. The report will also include an estimated water savings amount based on recommended adjustments to the controller's run times. 17 2024 Water Resource and Emergency Management Plan Town of Prosper fth 0P PIR Town of Prosper 2024 Water Resource and Emergency Management Plan 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 TCEQ every five years. 2024 Water Resource and Emergency Management Plan Town of Prosper Table of Contents Contents.................................................................................................................................... 2 1.0 INTRODUCTION.................................................................................................................. 3 1.01 MINIMUM REGULATORY REQUIREMENTS................................................................. 3 2.00 IMPLEMENTATION AND ENFORCEMENT....................................................................... 3 2.01 PROVISIONS TO INFORM THE PUBLIC AND OPPORTUNITY FOR INPUT ................ 3 2.02 PROGRAM FOR CONTINUING PUBLIC EDUCATION AND INFORMATION ................ 4 2.03 COORDINATION WITH THE REGIONAL WATER PLANNING GROUPS AND NTMWD4 2.04 INITIATION AND TERMINATION OF WATER RESOURCE MANAGEMENT STAGES. 4 A.

WATER MANAGEMENT MEASURES AVAILABLE UNDER STAGE 3.........................15 2 2024 Water Resource and Emergency Management Plan Town of Prosper 1.0 INTRODUCTION The Town of Prosper is a Customer 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. 1.01 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, 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. 2.00 IMPLEMENTATION AND ENFORCEMENT 2.01 PROVISIONS TO INFORM THE PUBLIC AND OPPORTUNITY FOR INPUT Town of Prosper provided opportunity for public input in the development of this Plan by the following means: • Posting the draft Plan on the community website and/or social media. • Providing the draft Plan to anyone requesting a copy. 3 2024 Water Resource and Emergency Management Plan Town of Prosper 2.02 PROGRAM FOR CONTINUING PUBLIC EDUCATION AND INFORMATION Town of Prosper informs and educates the public about the Plan by the following means: • Having copies of the plan available at City Hall and/or other appropriate locations. • Including information and making the Plan available to the public through the community website and/or social media. • Notifying local organizations, schools, and civic groups that utility staff are available to make presentations on the Plan (usually in conjunction with presentations on water conservation programs). • At any time that the Plan is activated or changes, Town of Prosper will notify local media of the issues, the water resource management stage (if applicable), and the specific actions required of the public. The information will also be publicized on the community website and/or social media. Billing inserts will also be used as appropriate. 2.03 COORDINATION WITH THE REGIONAL WATER PLANNING GROUPS AND NTMWD Appendix E of this Plan includes copies of the letters sent to the Chairs of the appropriate regional water planning groups as well as NTMWD. 2.04 INITIATION AND TERMINATION OF WATER RESOURCE MANAGEMENT STAGES A. INITIATION OF A WATER RESOURCE MANAGEMENT STAGE The Town Manager may order the implementation of a water resource management stage when one or more of the trigger conditions for that stage is met. • NTMWD has initiated a water resource management stage. (Stages imposed by NTMWD action must be initiated by Member Cities and Customers.) • Water demand is approaching a level that will cause a reduced delivery capacity for all or part of the distribution system. • Texas State Governor has declared a drought disaster declaration for Collin and/or Denton County. The following actions will be taken when a water resource management stage is initiated: ■ The public will be notified through local media and the supplier's website. 4 2024 Water Resource and Emergency Management Plan Town of Prosper ■ Wholesale customers and NTMWD will be notified by email that provides details of the reasons for initiation of the water resource management stage. ■ If any mandatory provisions of the Plan are activated, Town of Prosper will notify TCEQ and the NTMWD Executive Director within five business days. Instructions to report drought contingency plan water use restrictions to TCEQ is available online at https://www.tceq.texas.q.ov/drinkingwater/homeland security/security pws. B. TERMINATION OF A WATER RESOURCE MANAGEMENT STAGE Water resource management stages initiated by NTMWD may be terminated after NTMWD has terminated the stage. For stages initiated by the Town Manager, they may order the termination of a water resource management stage when the conditions for termination are met or at their discretion. The following actions will be taken when a water resource management stage is terminated: The public will be notified through local media and the supplier's website. ■ Wholesale customers and NTMWD will be notified by email. • If any mandatory provisions of the Plan that have been activated are terminated, Town of Prosper will notify TCEQ Executive Director and the NTMWD Executive Director within five business days. Instructions to report drought contingency plan water use restrictions to TCEQ is available online at https://www.tcea.texas.gov/drinkingwater/hnni eland security/security pws. The Town Manager may decide not to order the termination of a water resource management stage even though the conditions for termination of the stage are met. Factors which could influence such a decision include, but are not limited to, the time of the year, weather conditions, or the anticipation of potentially changed conditions that warrant the continuation of the water resource management stage. The reason for this decision should be documented. 2.05 PROCEDURE FOR GRANTING VARIANCES TO THE PLAN The director or designee may grant temporary variances for existing water uses otherwise prohibited under this Plan if one or more of the following conditions are met: • Failure to grant such a variance would cause an emergency condition adversely affecting health, sanitation, or fire safety for the public or the person or entity requesting the variance. • Compliance with this Plan cannot be accomplished due to technical or other limitations. 5 2024 Water Resource and Emergency Management Plan Town of Prosper ■ Alternative methods that achieve the same level of reduction in water use can be implemented. Variances shall be granted or denied at the discretion of the director or designee. All petitions for variances should be in writing and should include the following information: • Name and address of the petitioners. • Purpose of water use. • Specific provisions from which relief is requested. ■ Detailed statement of the adverse effect of the provision from which relief is requested. ■ Description of the relief requested. ■ Period of time for which the variance is sought. • Alternative measures that will be taken to reduce water use and the level of water use reduction. ■ Other pertinent information. 2.06 PROCEDURES FOR ENFORCING MANDATORY WATER USE RESTRICTIONS Mandatory water use restrictions may be imposed in Stage 1, Stage 2 and Stage 3. Staff will implement the Plan in accordance with adoption of the Plan. Appendix F contains a copy of the ordinance adopted regarding this Plan. The document designates responsible officials to implement and enforce the Plan. Administrative fees for violations to the Town's Water Conservation and Water Resource and Emergency Management Plan shall be added to the water account holder's regular monthly Town utility bill for city expenses incurred due to the account holder's violation as follows: First Offense: Courtesy Door Tag Warning Second Offense: Certified Letter notifying of violation. Third Offense: $100 Fourth and Subsequent Offenses: $300 Repeated offenses may result in water service shut off. 0 2024 Water Resource and Emergency Management Plan Town of Prosper 2.07 REVIEW AND UPDATE OF WATER RESOURCE AND EMERGENCY MANAGEMENT PLAN As required by TCEQ rules, the Town of Prosper 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 management stages include general, demand, supply, and emergency criteria. One of the major indicators of approaching or ongoing drought 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 total conservation storage when the lakes are full. Table 1 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 notifyTCEQ within five business days if these measures are implemented(http://www.tcecl.texas.goyIresPonse/drought-and- ou biic-water-systems_).
