FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: MAY 21, 2024
SUBJECT: 2024 WATER CONSERVATION AND DROUGHT CONTINGENCY PLAN
RECOMMENDATION: City Council to consider approval of the 2024 Water Conservation and
Drought Contingency Plan.
FUNDING SOURCE: None
BACKGROUND: On March 5, 2024, Grapevine City Council approved changes to the
Drought Contingency ordinance that eliminated conflict for drought stage
triggers following Texas Regional Water District (TRWD) guidance. The
Drought Contingency ordinance is a subset of the overall Water
Conservation Plan that staff is recommending in this item.
The Texas Commission on Environmental Quality (TCEQ) requires public
water suppliers to approve an updated water conservation and drought
contingency plan every five years that complies with their guidelines and
requirements. The only material change between the plan approved in
2019 and this one is related to current and projected water usage.
The City of Grapevine adopted its initial drought contingency plan in 1988.
The plan was subsequently updated in 1997, 2006, 2009, 2011 and 2019.
Staff recommends approval.

1. INTRODUCTION AND OBJECTIVES
Water supply has always been a key issue in the development of Texas. In recent years, the
increasing population and economic development in Region C have led to growing demands for
water. At the same time, local and less expensive sources of water supply are largely developed.
Additional supplies to meet higher demands will be expensive and difficult to develop. Severe
drought conditions in recent years have highlighted the importance of efficient use of our
existing supplies to make them last as long as possible. This will delay the need for new supplies,
minimize the environmental impacts associated with developing new supplies, and delay the
high cost of additional water supply development.
Recognizing the need for efficient use of existing water supplies, the Texas Commission on
Environmental Quality (TCEQ) has developed guidelines and requirements governing the
development of water conservation and drought contingency plans for public water suppliers.
The TCEQ guidelines and requirements for public water suppliers are included in
Appendix A. The City of Grapevine has adopted this water conservation and drought
contingency plan pursuant to TCEQ guidelines and requirements.
The objectives of the water conservation plan are:
• To reduce water consumption from the levels that would prevail without conservation
efforts.
• To reduce the loss and waste of water.
• To identify the level of water reuse.
• To improve efficiency in the use of water.
• To extend the life of current water supplies by reducing the rate of growth in demand.
The objectives of the drought contingency plan are:
• To conserve the available water supply in times of drought and contingency.
• To maintain supplies for domestic water use, sanitation and fire protection.
• To protect and preserve public health, welfare, and safety.
• To minimize the adverse impacts of water supply shortages.
• To minimize the adverse impacts of emergency water supply conditions.

Water Conservation and Drought Continpencv Plan City of Grapevine
3.3 Specification of Water Conservation Goals
Table 1 shows current per capita water use and per capita water use goals for the City of
Grapevine. Water use is shown in units of gallons per capita per day (gpcd).
Residential gallons per capita per day (Residential GPCD) is defined as the total gallons sold
for residential use by a public water supplier divided by the residential population served
and divided by the number of days in the year.
Total gallons per capita per day (Total GPCD) is defined as the total amount of water
diverted and/or pumped for potable use divided by the total permanent population divided
by the days of the year. Diversion volumes of indirect reuse shall be credited against total
diversion volumes for the purposes of calculating GPCD for targets and goals.
The City's water conservation goals include the following:
• Maintain the total and residential per capita water use in a dry year below the
specified amounts in gallons per capita per day (Table 1).
• Implement and maintain a meter replacement program (Section 3.5).
• Maintain water loss in the system less than 10 percent annually (Section 3.6).
• Raise public awareness of water conservation and encourage responsible public
behavior through a public education and information program, as discussed in 3.7.
• The Tarrant Regional Water District (TRWD) will coordinate water conservation
workshops for staff of customer cities that receive water, directly or indirectly, from
TRWD. Recent workshops have covered topics related to automated metering
infrastructure, leak detection, water loss audits, and effective communication. The
City of Grapevine will work with TRWD to support our staff with workshop topics,
promotion and coordination.
• Since 2008, the Annual North Texas Regional Water Conservation Symposium has
been jointly coordinated by the region's three major water providers — Dallas Water
Utilities, North Texas Municipal Water District and TRWD. The event invites staff
from customer cities to hear from speakers from across the state and nation about
their experience and expertise. Discussions center on key elements of successful
water conservation programs, communications, weather and climate, education,
etc. The City of Grapevine staff will supports the annual symposium by attending,
participating and considering the adoption of presented programs and strategies.
• By May 1st of each year, conservation implementation reports are required to be
submitted to the Texas Water Development Board (TWDB). Additionally, a utility
profile is submitted every 5 years. The City of Grapevine will share these reports
with TRWD so they can be included in an overall regional report and evaluation of
regional conservation program effectiveness.
• TRWD participates in the regional water conservation public awareness campaign
with Dallas Water Utilities. The current campaign, Water is Awesome is entering its
Water Conservation and Drouqht Continqencv Plan City of Grapevine
9t" year and includes television, radio, print, and digital media. Media outreach is
used to increase public awareness on the value of water and encourage adoption of
outdoor water efficient behaviors. The City of Grapevine will support the regional
campaign by using, promoting and sharing related campaign resources to our
customers.
• The TRWD Residential Sprinkler System Evaluation Program uses trained licensed
irrigators to assess residential sprinkler systems. Upon inspection they make
recommendations for improving system performance, identify repair needs, and
instruct users on how to schedule controllers to eliminate unnecessary outdoor
watering. The evaluation also includes an opportunity to educate residents about
their sprinkler systems and offer guidance on how much and how long to water
throughout the year. The City of Grapevine will participate in and promote the
sprinkler system evaluation program to residential customers.
• TRWD owns and operates four weather stations in Tarrant County. The stations are
integrated into the Texas ET Network. Texas ET Network and National Weather
Service data is used to calculate accurate weekly watering advice across North
Central Texas and the service is map based. Users can sign up to receive weekly
emails and/or text messages every Monday for that week's watering advice. The
advice is also shared through social media channels and SaveTarrantWater.com. The
program gives residents information to water only when needed and to reduce
overwatering. It is a regional program and joint -funded with Dallas Water Utilities.
The City of Grapevine will promote the weekly watering advice and encourage
participation to our customers.
• TRWD operates and maintains SaveTarrantWater.com as a resource to consumers.
Regional conservation program information, DIY videos, and Green Pros listing can
be found on the website. Save Tarrant Water is also active on social media as a way
to promote new information, provide tips, and support customer city efforts. The
City of Grapevine will promote and share Save Tarrant Water resources to our
customers.
In 2018, TRWD provided contracted water efficiency assessments to local school
districts. The assessments provide an inventory of all indoor water -using fixtures and
appliances. Cooling towers and sprinkler systems are also inspected.
Recommendations for fixture replacements and process improvements are backed
with estimated costs and payback periods. The assessments consider water,
wastewater, energy and chemical savings. TRWD will continue to work with local
school districts for ICI water efficiency assessments. If school district participation
decreases, TRWD will coordinate with customer cities to identify potential
commercial and industrial customers. The City of Grapevine will coordinate with
TRWD to help promote the assessment opportunity to our ICI customers.

City of Grapevine
• Traditionally, TRWD has invited customer cities to one or two meetings a year to
discuss programs, issues and collaboration opportunities to implement conservation
outreach initiatives. Those meetings will continue but will also be supplemented
with monthly conference calls throughout the year. The goal is to increase
communication, partnership and program implementation with all customer cities.
The City of Grapevine will actively participate in conservation coordinators meetings.

3.4 Accurate Metering of Raw Water Supplies and Treated Water
Deliveries
The City of Grapevine meters its raw water flow from Lake Grapevine using magnetic flow
meters with an accuracy of +/- 5.0%. The City meters its treated water deliveries to the
distribution system from the water treatment plant using four magnetic flow production
meters with an accuracy of +/- 5.0%. The meters are calibrated on an annual basis by a third
party contractor to maintain the required accuracy and ensure repairs and/or replacements
are administered as needed.

Water Conservation and Drought Continpencv Plan City of Grapevine
3.5 Metering of Customer and Public Uses and Meter Testing, Repair,
and Replacement
Water usage for all customers of the City of Grapevine, including public and governmental
users, is metered.
As part of this water conservation plan, the City of Grapevine will implement a meter
replacement program that will replace every meter on a 10-year cycle. Initial efforts will
focus on the oldest meters in the system.
In addition, meters registering any unusual or questionable readings will be tested and
repaired to restore full functionality.
3.6 Determination and Control of Water Loss
The City of Grapevine will conduct an annual water audit using the TWDB's water audit
worksheet. Total water loss is the volume of raw water drawn from Lake Grapevine minus
metered deliveries to customers minus other authorized consumption (e.g., authorized but
unmetered uses such as firefighting and line flushing).
The TWDB water audit worksheet divides total water losses into apparent losses and real
losses:
• Apparent water loss is water which is used by customers but for which the utility is
not compensated. Reducing apparent losses increases the city's utility revenue but
does not reduce water usage. Apparent water losses include:
o Inaccuracies in customer meters (customer meters tend to run more slowly
as they age and under -report actual use).
o Unauthorized consumption.
o Systematic data handling errors.
• Real water loss is water which is physically lost from the water system before it can
be used by customers. Identifying and preventing real losses decreases a utility's
costs and decreases water usage. Real water losses include:
o Reported leaks.
o Unreported leaks.
To meet the water loss targets established in Table 1, the City has implemented the water
loss control strategies described in Section 4.1. As shown in Appendix B, Infrastructure
Leakage Index for the City of Grapevine has varied from 0.81 ILI to 1.70 ILI in the last five
years. With the measures described in this plan, the City of Grapevine intends to maintain
the ILI below 5 ILI in 2029 and subsequent years. If ILI exceeds this goal, the City of Grapevine
will implement a more intensive audit to determine the source(s) of water loss and will
implement more intensive strategies to reduce the water loss.

3.7 Continuing Public Education and Information Campaign
The continuing public education and information campaign on water conservation for the
City of Grapevine includes the following elements:
• Promote the City's water conservation measures (presented in Chapters 3, 4, and 5).
• Conduct tours of the City of Grapevine's Water Treatment Plant for local schools and
various organizations to educate patrons about the water treatment process and
promote water conservation.
• Promote Save Tarrant Water website (www.SaveTarrantWater.com)
• Host water conservation booths at several city events throughout each year.

4. ADDITIONAL REQUIRED WATER CONSERVATION PLAN CONTENT
The Texas Administrative Code also includes additional requirements for water conservation
plans for public drinking water suppliers that serve a population of 5,000 people or more
and/ or a projected population of 5,000 people or more within the next ten years:
• §288.2(a)(2)(A) — Leak Detection, Repair, and Water Loss Accounting — Sections 3.6
and 4.1
• §288.2(a)(2)(B) — Requirement for Water Conservation Plans by Wholesale
Customers — Section 4.2
4.1 Leak Detection and Repair and Pressure Control
Measures to control water loss are part of the routine operations of the City of Grapevine.
Meter readers watch for and report signs of illegal connections so they can be addressed
quickly. Crews and personnel look for and report evidence of leaks in the water distribution
system. Maintenance crews respond quickly to repair leaks reported by the public and city
personnel. The City of Grapevine spends $150,000 per year to repair and replace water
distribution lines and uses 10 distribution line maintenance technicians. Areas of the water
distribution system in which numerous leaks and line breaks occur and undesirable pipe
materials are located, are targeted for replacement as funds are available.
To reduce real water losses, the City of Grapevine will maintain a proactive water loss
program. As part of this program, the City will implement the following actions:
• Conduct regular inspections and soundings of all water main fittings and
connections;
• Install temporary leak noise detectors and loggers;
• Limit surges in pressure;
• Monthly training programs to include proper meter repair techniques, pipe tapping
procedures, line break repairs, etc.;
• Valve cycling program to achieve every valve within the system to be cycled at a
minimum of two years;
• Maintain and/ or improve equipment necessary to maximize man -power in the field.
4.2 Requirement for Water Conservation Plans by Wholesale Customers
At this time, the City of Grapevine is not a wholesale water provider. After adoption of this
plan, each contract for the wholesale sale of water by the City of Grapevine will include a
requirement that the wholesale customer develop and implement a water conservation
plan meeting the requirements of Title 30, Part 1, Chapter 288, Subchapter A, Rule 288.2 of
the Texas Administrative Code. This requirement will also extend to each successive
wholesale customer in the resale of the water.

5. MONITIORING OF EFFECTIVENESS AND EFFICIENCY— CONSERVATION
REPORTS
5.1 Five -Year Water Conservation Implementation Report
The City of Grapevine has completed a water conservation implementation report
(Appendix C) to accompany this plan. The city will use this report to monitor the
effectiveness and efficiency of the water conservation program and to plan conservation -
related activities. In this report, the city has documented water use accounting, system
data, per -capita water use and water loss, water conservation programs and activities, and
estimated water savings for previous five years. In addition, the city has compared current
per capita water use to the targets and goals established in this plan (Section 3.3).
5.2 Annual Water Conservation Report
The City of Grapevine will also file an annual conservation report with the TWDB
(Appendix D). This form will be filed by May 1st for the preceding calendar year and will be
used by the City of Grapevine to monitor the effectiveness and efficiency of the water
conservation program and to plan conservation -related activities for the next year. The
form records water use accounting, system data, per -capita water use and water loss, water
conservation programs and activities, and estimated water savings for the year and
compares progress to the targets and goals established in this plan (Section 3.3).

6. DROUGHT CONTINGENCY PLAN
6.1 Introduction
The purpose of the drought contingency plan is as follows:
• To conserve the available water supply in times of drought, water supply shortage,
and emergency
• To maintain supplies for domestic water use, sanitation, and fire protection
• To protect and preserve public health, welfare, and safety
• To minimize the adverse impacts of water supply shortages
• To minimize the adverse impacts of emergency water supply conditions
In the absence of drought response measures, demand tends to increase during a drought
due to increased demand for irrigation. The severity of a drought depends on the degree of
depletion of supplies and on the relationship of demand to available supplies.
A water supply shortage can be the result of drought or the result of conditions which may
render all or some portion of the water supply unavailable. These conditions can include
but are not limited to the presence of invasive species, contamination of the water supply,
or infrastructure failure.
6.2 Adoption of Tarrant Regional Water District Drought Contingency
Plan
The City of Grapevine has adopted TRWD's Drought Contingency Plan. As a water customer
of TRA and TRWD, the City shall impose the TRWD water conservation measures when
requested to do so in accordance with the TRWD Drought Contingency Plan, as amended.

the next ten years subsequent to the effective date of the plan must include the following elements:
(A) a program of leak detection, repair, and water loss accounting for the water transmission, delivery, and
distribution system;
(B) a requirement in every wholesale water supply contract entered into or renewed after official adoption of
the plan (by either ordinance, resolution, or tariff), and including any contract extension, that each successive
wholesale customer develop and implement a water conservation plan or water conservation measures using the
applicable elements in this chapter. If the customer intends to resell the water, the contract between the initial
supplier and customer must provide 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 this chapter.
(3) Additional conservation strategies. Any combination of the following strategies shall be selected by the
water supplier, in addition to the minimum requirements in paragraphs (1) and (2) of this subsection, if they are
necessary to achieve the stated water conservation goals of the plan. The commission may require that any of
the following strategies be implemented by the water supplier if the commission determines that the strategy is
necessary to achieve the goals of the water conservation plan:
(A) conservation -oriented water rates and water rate structures such as uniform or increasing block rate
schedules, and/or seasonal rates, but not flat rate or decreasing block rates;

TARRANT REGIONAL WATER DISTRICT
DROUGHT CONTINGENCY AND EMERGENCY
WATER MANAGEMENT PLAN
MAY 2024
Tarrant Regional Water District
800 East Northside Dr.
Fort Worth, TX 76102
1. DROUGHT CONTINGENCY AND EMBERGENCY WATER MANAGEMENT
PLAN
1.1 Introduction
The purpose of this drought contingency and emergency water management plan is as follows:
■ To conserve the available water supply in times of drought and emergency
■ To maintain supplies for domestic water use, sanitation, and fire protection
■ To protect and preserve public health, welfare, and safety
■ To minimize the adverse impacts of water supply shortages
■ To minimize the adverse impacts of emergency water supply conditions.
TRWD and its customer cities experienced Stage 1 drought restrictions from 2011-2012 and 2013-
2015. Fortunately, water supply reservoirs have not dropped below 75% capacity since. With that
experience, the District has taken a more active role in educating the public about the importance
of reducing water waste and being prepared for the next drought.
1.2 State Requirements for Drought Contingency Plans
This drought contingency and emergency water management plan is consistent with the Texas
Commission on Environmental Quality (TCEQ) guidelines and requirements for the development
of drought contingency plans by wholesale water suppliers, contained in Title 30, Part 1, Chapter
288, Subchapter B, Rule 288.22 of the Texas Administrative Code. This rule is included in

1.3 Provisions to Inform the Public and Opportunity for Public Input
TRWD provided opportunity for public input in the development of this drought contingency and
emergency water management plan by the following means:
■ Several meetings with customer representatives were held to discuss and coordinate the
development of this plan.
■ The District will provide the draft plan to anyone requesting a copy.
■ The proposed plan was posted to SaveTarrantWater.com web site (April 2024) providing
the public an opportunity to review and comment on the plan in writing.
■ Public comment was available at the Tarrant Regional Water District board meeting held
at the District offices in Fort Worth at 9:00 a.m. on Tuesday, April 16, 2024.
1.4 Initiation and Termination of Drought Response Stages
Initiation of Drought Response Stage
The General Manager may order the implementation of a drought response stage or water
emergency when one or more water supply trigger conditions is met. The following actions will
be taken when a drought stage is initiated:
■ The designated representative(s) of primary wholesale customers will be notified by email,
mail, telephone, or fax that provides details of the reasons for initiation of the drought stage.
■ The public will be notified through local media following the notification of primary
wholesale customers.
■ If any mandatory provisions of the drought contingency plan are activated, TRWD will
notify TCEQ within five business days.
Notwithstanding the foregoing, the General Manager may decide, under special circumstances, not
to order the implementation of a drought response stage or water emergency even though one or
more of the trigger criteria for the stage are met. Factors which could influence such a decision
include, but are not limited to, the time of year, weather conditions, the anticipation of replenished
water supplies, or the anticipation that additional facilities will become available to meet needs.
The trigger conditions in this plan pertaining to TRWD's system volume were established
following an intensive study of the North Texas climate and its impact on water supplies by Hydros
Consulting, Inc. (Hydros), an engineering firm based in Boulder, Colorado. The 2007 study
projected the effects of simulated weather patterns on the combined storage capacity of TRWD
reservoirs. Using computer simulations, Hydros compared the water savings that would be
achieved at various trigger points with and without outdoor watering restrictions in place. Under
severe drought conditions, the estimated water savings that would be achieved by implementing
this plan would extend water supplies by several weeks. In late 2023/early 2024, Hydros completed
a sensitivity analysis of TRWD's water supply system to variations in the existing drought triggers.
The sensitivity analysis included updated infrastructure, operations, permitting, supplies and
demands, and evaluated whether adjusting the existing drought triggers would have a meaningful
impact on water supply availability. Based on the results of the analysis, staff has determined the
best decision for the system and TRWD water customers at this time is to maintain the same
drought trigger conditions as the previous plan.
Termination of a Drought Stage
The General Manager will order the termination of a drought response stage or water emergency
when the conditions for termination are met. The following actions will be taken when a drought
stage is terminated:
The designated representative(s) of primary wholesale customers will be notified by email,
mail, telephone, or fax that provides details of the reasons for termination of the drought
stage.
The public will be notified through local media following the notification of primary
wholesale customers.
When mandatory provisions of the drought contingency plan that have been activated are
terminated, TRWD will notify the Executive Director of the TCEQ within five business
days.
Notwithstanding the foregoing, the General Manager may decide, under special circumstances, not
to order the termination of a drought response stage or water emergency even though conditions
for termination of the stage are met. Factors which could influence such a decision include, but are
not limited to, the time of year, weather conditions, or the anticipation of potential changes in
conditions that warrant the continuation of the drought stage.
1.5 Drought and Emergency Response Stages and Measures
Stage 1, Water Watch
Triggering and Terminating Conditions
■ Total combined raw water supply in TRWD water supply reservoirs (Bridgeport, Eagle

State 3, Water Emer2encv
Tri22erin2 and Terminating Conditions
■ Total raw water supply in TRWD water supply reservoirs (Bridgeport, Eagle Mountain,
Richland Chambers and Cedar Creek) drops below 45% (55% depleted) of conservation
storage capacity.
■ Water demand has exceeded or is expected to exceed 90% of maximum sustainable
production of delivery capacity for an extended period.
■ Water demand for all or part of the TRWD delivery system approaches delivery capacity
because delivery capacity is inadequate.

system components.
0 The General Manager finds that conditions warrant the declaration of a Stage 3 drought.
Subject to preceding paragraphs regarding the Termination of a Drought Response stage, Stage 3,
Water Emergency, will be terminated when the total combined raw water supply in TRWD's West
Fork and East Texas reservoirs exceeds 60% of conservation storage or remains at or above 55% for
30 consecutive days, whichever occurs first.
Goal for Use Reduction
The goal for water use reduction under Stage 3, Water Emergency, is to decrease use by 20 percent.
If circumstances warrant, the General Manager can set a goal for greater water use reduction.
Actions Available under State 3, Water Emergency
The General Manager can order the implementation of any of the actions listed below, as deemed
necessary. The General Manager may order the implementation of additional actions not listed
below, as deemed necessary. Measures imposing mandatory requirements on customers require
