Water Conservation
and
Drought Contingency Plan
1. INTRODUCTION AND OBJECTIVES
Water supply has always been a key issue in the development of Texas. In recent years, the
incrcasing population and economic development in Region C have led to growing demands for
water. Additional supplies to meet higher demands will be expensive and difficult to develop.
Therefore, it is important that we make efficient use of existing supplies and 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 City of Coppell has adopted this water conservation and drought contingency plan pursuant
to TCEQ guidelines and requirements.
The ot?jectives of the water conservation plan are:
· To reduce water consumption.
· 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 ot?jectives of the drought contingency plan are:
· 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 minimizc the adverse impacts of water supply shortages.
· To minimize the adverse impacts of emergency water supply conditions.
2. TEXAS COMMISSION ON ENVIRONMENTAL QUALITY RULES
2.1
Conservation Plans
']['he TCEQ Rules governing development of water conservation plans for public water suppliers
are contained in Title 30, Part 1, Chapter 288, Subchapter A, Rule 288.2 of the Texas
Administrative Code, which is included in Appendix B. For the purpose of these roles, a water
conservation plan is defined as:
Page 5 of 60
"A strategy or combination of strategies for reducing the volume of water withdrawn from a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."
According to TCEQ rules, water conservation plans for public water suppliers must have a
certain minimum content (Section 3), must have additional content for public water suppliers that
are projected to supply 5,000 or more people in the next ten years (Section 4), and may have
additional optional content (Section 5).
2.2.
Drought Contingency Plans
The TCEQ Rules governing development of drought contingency plans for public water
suppliers are contained in Title 30, Part 1, Chapter 288, Subchapter B, Rule 288.20 of the Texas
Administrative Code, which is included in Appendix B. For the purpose of these rules, 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. A drought contingency plan may be a separate document identified as such or may
be contained within another water management document."
The drought contingency plan for the City of Coppell is contained in Section 6 of this water
conservation and drought contingency plan.

3.2 Specification of Water Conservation Goals
Table 3.2 shows projected per capita municipal uses obtained from the Texas Water
Development Board (TWDB) and interpolated to match the appropriate years for the 5-year and
10-year goals. The TWDB projections are applicable for a dry year, in which outdoor xvater use
would be high. Per capita municipal w'ater use in a year xvith normal or high precipitation during
the summer should be less than projected here.

Table 3.3 shows historical and projected per capita municipal water use for the City of Coppell.
Water use is shown in units of gallons per capita per day (gpcd). Municipal water use is total use
less wholesale sales to other municipal suppliers less sales to industrial users. Per capita
municipal water use is municipal water use divided by population. The per capita municipal
water use does not include industrial use.
The TWDB projections include the impact of low-flow plumbing fixtures and water conservation
measures that have been in effect since at least 2000 but do not include the effect of water
conservation measures recommended in this plan. Table 3.3 shows the projected per capita
water use after implementation of this water conser~,ation and drought contingency plan.

The City's water conservation goals include the following:
· Achieve year 2010 per capita municipal water use of 212 gpcd or less, as shown in Table 3.3.
This represents a reduction of 16 gpcd from the TWDB's projected per capita municipal
water use without low-flow plumbing fixtures and other conservation measures in place since
2000.
Achieve year 2015 per capita municipal water use of 210 gpcd or less, as shown in Table 3.3.
This represents a reduction of 18 gpcd from the TWDB's projected per capita municipal
water use without low-flow plumbing fixtures and other conservation measures in place since
2000.
· Implement and maintain a meter replacement program (Section 3.4).
· Keep the level of unaccounted water in the system less than 8 percent in 2010 and subsequent
years (Section 3.5).
· Raise public awareness of water conservation and encourage responsible public behavior
through a public education and information program (Section 3.6).
· Decrease outdoor water use by implementing the following program:
Drought resistant landscaping in the medians of City streets.
3.3 Accurate Metering of Treated Water Deliveries
All treated water is metered through the City of Dallas' Rate of Flow Controller at 1101 Village
Parkway. This device is tested every two months by the City of Dallas and has an accuracy of
± 0.3% average. The City of Coppell meters all water leaving our pump station through a
transient time meter which is tested twice a year and has an accuracy of+ 1%.
3.4
Metering of Customer and Public Uses and Meter Testing~ Repaih and
Replacement
Water usage for all customers of the City of Coppell, including public and governmental users, is
metered.
As part of this water conservation plan, the City of Coppell will implement a meter replacement
program that will replace every residential meter on a lO-year cycle. Initial efforts will focus on
the oldest meters in the system. The City currently replaces about 1100 meters every year.
In addition, residential meters registering any unusual or questionable readings will be replaced
when the irregularity is noticed, regardless of age.
Page 9 of(~0
3.5 Determination and Control of Unaccounted Water
Unaccounted water is the difference between treated water obtained from Dallas and metered
sales by Coppell to our customers. Unaccounted water can include several categories:
· Inaccuracies in customer meters (customer meters tend to run more slowly as they age and
under-report actual use);
· Losses due to water main breaks and leaks in the water distribution system.;
· Losses due to flushing of lines;
· Losses due to illegal connections;
· Losses due to fire fighting efforts; and
· Other.
Apparent water losses include water that was actually used but not accounted for, such as
customer meter errors or theft. Accounting for apparent losses increases the city's utility
revenue but does not reduce water usage. Real losses include leakage and overflows at the water
facilities. Identifying and preventing real losses decreases a utility's costs and decreases water
usage.
Strategies to address apparent water loss:
· Meter replacement as noted in Section 3.4;
· Meter all flushing of water lines;
· Monitor construction activity to ensure meters are used, especially when new lines are being
flushed prior to being placed in service; and
· Work closely with Fire Department to estimate water used in fire fighting activities.
Strategies to address real water Ioss:
· Respond to ali identified water leaks within two hours and make repairs within 24 hours after
utility locates, and estimate total unaccounted for water for tracking purposes;
· Replace one segment of the water system yearly that has experienced two or more leaks.
As shown in Appendix C, unaccounted water for the City of Coppell has varied from 0.77
percent to 9.85 percent in the last five years. With the measures described in this plan, the City
of Coppell intends to maintain the unaccounted water below 8 percent in 2010 and subsequent
years. If unaccounted water exceeds this goal, the City of Coppell will implement a more
intensive audit to determine the source(s) of water loss and reduce the unaccounted water.
3.6 Continuing Public Education and Information Campaign
The continuing public education and information campaign on water conservation for the City of
Coppell includes the following elements:
Page 10 of 60
include inserts on water conservation with water bills at least twice per year. Inserts will
include material developed by City of Coppell staff and material obtained from the TWDB,
the TCEQ, and other sources.
· Encourage local media coverage of water conservation issues and the importance of water
conservation.
Make the Texas Smartscape CD, water conservation brochures, and other water conservation
materials available to the public at the City of Coppell Utility Department and other public
places.
Make information on water conservation available online at www.ci.coppell.tx.us and
include links to the Texas Smartscape web site and to information on water conservation on
the TWDB and TCEQ web sites.
· Provide information on water conservation on the City's cable access channel.
3.7 Non-Promotional Water Rate Structure
With the intent of encouraging water conservation and discouraging waste and excessive use of
water, the City of CoppelI has adopted an increasing block rate water structure where the unit
price of water increases with increasing water use. Current water rates are shown in Tables 3.4
and 3.5.

Page 12 of 60
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(2)(A) Leak Detection, Repair, and Water Loss Accounting - Sections 3.5, 4.1, and
5.5
· §288.2(a)(2)(B)- Record Management System Section 4.2
· §288.2(a)(2)(C) Requirement for Water Conservation Plans by Wholesale Customers
Section 4.3
4.1 Leak Detection and Repair; Pressure Control
Measures to control unaccounted water are part of the routine operations of the City of Coppeli.
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 Coppell spends $550,000 per year to maintain and make repairs to the water
distribution system. The City has 2 (6 full time employees) distribution line maintenance crews.
Areas of the water distribution system in which numerous leaks and line breaks occur are
targeted for replacement as fimds are available. In fiscal year 2003-04, the City expended
S350,000 to replace water lines.
To reduce real water losses, the City of Coppell will maintain a proactive water loss program.
As part of this program, the City will implement the following actions:
· Respond to leaks within two hours and repair within 24 hours after utility locates;
· Replace residential meters showing irregular readings within five working days;
· Control pressure to above the minimum standard-of-service level including fire requirements;
and
· Limit surges inpressure.
4.2 Record Management System
As required by TAC Title 30, Part 1, Chapter 288, Subchapter A, Rule 288.2(a)(2)(B), the record
management system for the City of Coppell records water pumped, water delivered, and water
sold; estimates water losses; and allows for the separation of water sales and uses into residential,
commercial, public/institutional, and industrial categories.
Page 13 of 60
4.3 Requirement for Water Conservation Plans by Wholesale Customers
At this time, the City of Coppell is not a wholesale water provider. After adoption of this plan,
any contract for the wholesale sale of water by the City of Coppell will include a requirement
that the wholesale customer develop and implement a water conservation plan meeting the
requirements of Title30, 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.

6. DROUGHT CONTINGENCY PLAN
6.1 Declaration of Policy~ Purpose~ and Intent
In order to conserve the available water supply and protect the integrity of water supply
l~acilities, with particular regard for domestic water use, sanitation, and fire protection,
and to protect and preserve public health, welfare, and safety and minimize the adverse
impacts of water supply shortage or other water supply emergency conditions, the City of
Coppell hereby adopts the lbllowing regulations and restrictions on the delivery and
consumption of water.
Water uses regulated or prohibited under this Daily Water Conservation and Drought
Contingency Plan (the Plan) are considered to be non-essential and continuation of such
uses during times of water shortage or other emergency water supply condition are
deemed to constitute a waste of water which subjects the offender(s) to penalties as
defined in Section H of this Plan.
6.2 Public Education
The City of Coppell will periodically provide the public with information about the Plan,
including information about the conditions under which each stage of the Plan is to be
initiated or terminated and the drought response measures to be implemented in each
stage. The City may provide public education concerning the provisions of the water
conservation to include, but not limited to, the following:
WebPage
Water bill inserts
Direct mail-outs
Publication in the official City newspaper
Press releases to local and area media
City's cable access channel
Periodic status reports to the City Council on drought response programs, water
emergencies and their results.
6.3 Coordination with Regional Water Planning Groups
The City of Coppell purchases treated water through a wholesale water supply contract
by and between the City of Dallas. If there is a shortage in the water supplied to the City
from any cause, Dallas Water Utilities (DWU) or other supplier may reduce the volume
of treated water that is supplied. The reduction in the water distributed to the City is on a
pro rata basis among all of the wholesale customers of the water supplier. If DWU or
other water supplier imposes a curtailment on water delivered, the City is required to
cooperate by imposing conservation measures.
Page 15 of 60
DWU, the current supplier, or other water supplier has implemented a Drought
Contingency Plan that includes water use restrictions that are applicable to the City of
Coppell. The proposed stages and initiation conditions in this Plan are in accordance
with the provisions established by DWU or other water supplier.
The service area of the City of Coppell is located within the Region C Regional Water
Planning Group. The City of Coppell provided information to Chiang, Patel and Yerby,
Inc. for inclusion in the "2000 Update Long Range Water Supply Plan" for Dallas Water
Utilities.

Yes No . If yes, approximately __MGD. N/A
4. Please describe the water system. Include the number of treatment plants, wells, and
storage tanks, If possible, include a sketch of the system layout.
The City of Coppell Water Distribution System is comprised of two ground storage
reservoirs (GSR), one water pump station, two elevated storage tanks (EST) and the
distribution piping. The GSR's and the water pump station are located at 1101 Village
Parkway Drive. The EST's are located at 1001 Northpoint Drive and 520 Southwestern
Blvd. The distribution piping is located within city right of way or easements.
Treated water is purchased from the City of Dallas. The City of Coppell does not have
a xvater source nor does it provide any full-scale water treatment. The City of Dallas
pumps treated water from its Elm Fork Treatment Plant, locate in Carrollton, Texas
directly into thc GSR's via a rate of flow controller located at the pump station.
The GSR's have a total storage capacity of 10 million gallons. The Village Parkway
Pump Station was constructed in 1989, along with a 4 million-gallon GSR. A 6
nfillion-gallon GSR was constructed in 1997, along with the expansion of the pump
station.
The pump station pumps treated water from the GSR's into the distribution system.
The pump station has one 600 HP pump, three 450 HP pumps and two 250 HP pumps.
The pump station has two separate 4160 volt power sources. Each power source is
Page 46 of 60
capable of running all six pumps at the same time. There is also a diesel generator at
the pump station that can operate both 250 HP pumps at the same time. The pump
station has the ability to supply up to 28 MGD. Our current usage, on a max day, is
about 17 MGD. The pump station also has a small chlorination unit that is used to
improve the chloramine residual during the winter months, when water usage is at a
minimum.
The entire city operates on one pressure plane. The distribution system is made up of
over 860,000 feet of pipe rm~ging in diameter from 2 inches to 30 inches. However,
most of the system is 8" or greater. In addition to the piping, the distribution system
contains about 1950 fire hydrants, 3900 valves and various other appurtenances.
The EST's are both located on the western edge of the city. The EST at 520
Southxvestem Blvd. has a capacity of 1.5 million gallons and was constructed in 1981.
The EST at 1001 Northpoint Drive has a capacity of 2 million gallons and was
constructed in 1999. Both tanks provide storage capacity and pressurize the
distribution system.
IV. WASTEWATER UTILITY SYSTEM

Is treated effluent used for irrigation on-site N/A, plant washdown N/A, or
chlorination~dechlorination N/A? If yes, approximately gallons per month.
Could this be substituted for potable water new being used in these areas ?
Briefly describe the wastewater system(s) of the area services by the water utility.
Describe how treated wastewater is disposed of. Where applicable, identify treatment
plant(s) with the TCEQ name and number, the operator, owner, and if wastewater is
discharged, the receiving stream. Please provide a sketch or map which located the
plant(s) and discharge or disposal sites.
The City of Coppell Wastewater Collection System is comprised of collection pipes
and two lift stations. The lift stations are located at 1098 E. Sandy Lake Road and 600
Deforest Road. The collection pipes are located within right of way or easements. The
Trinity River Authority Wastewater Treatment Plant (TRA) on Singleton Blvd. in
Grand Prairie treats our wastewater.
The Deforest Road Lift Station currently receives a peak flow a 6.4 MGD and is
operating near capacity. Wastewater is pumped from the Deforest Road Lift Station to
thc Sandy Lake Road Lift Station via a 16" force main and gravity piping. The Sandy
Lake Road Lift Station currently receives a peak flow of 3.8 MGD, in addition to the
6.4 MGD from the Deforest Road Lift Station, for a total peak flow of 10.2 MGD. The
Page 47 of 60
wastewater is pumped to the TRA interceptor via a 30" force main. There is also a
small amount of wastewater that feeds directly into the TRA interceptor via a 30"
gravity line. TRA treats approximately 4 MGD for the City of Coppell.
The City of Coppell is currently upgrading the lift stations and force mains. The
improvements should be operational by the fall of 2005. These improvements include a
new Deforest Road Lift Station with a peak flow capacity of 14.16 MGD and a
rehabilitated Sandy Lake Road Lift Station with a peak flow of 4.24 MGD. Once the
improvements are operational, the Deforest Road Lift Station will pump directly into
the TRA interceptor via a new 30" force main and the Sandy Lake Road Lift Station
will pump directly into the TRA interceptor via a new 20" force main. These
improvements will meet the year 2020 projected future peak flows.
The collection system pipe network is made up of over 815,000 feet of pipe ranging in
diameter from 3 inches to 36 inches and about 1975 manholes. Most of the sewer
services are 4" pipe.

VI. CONSERVATION GOALS
Please use the data provided in this survey to establish conservation goals (additional data may
be used).
Page 49 of 60
Water conservation goals for municipal utilities are generally established to maintain or
reduce consumption, as measured in:
1. gallons per capita per day used;
2. unaccounted-for water uses;
3. peak-day to average-day ratio; and/or
4. an increase in reuse of recycling or water.
TCEQ/TWDB conservation staff assess the reasonableness of water conservation goals
based on whether the applicant addresses the following steps:
1. identification of a water or wastewater problem;
2. completion of the utility profile;
3. selection of goals based on the technical potential to save water as identified in the
utility profile; and
4. performance of a cost-benefit analysis of conservation strategies.
If at least the first three steps have been completed and are summarized in the water
conservation plan, then staff can conclude that there is substantiated basis for the
goals, and that the water conservation plan is integrated into water management.
Therefore, the established conservation goals can be deemed reasonable.

APPENDIX CI
Definitions of Utility Profile Terms
Residential sales should include residential sales to residential class customers only.
Industrial sales should include manufacturing and other heavy industry.
Commercial sales should include all retail businesses, offices, hospitals, etc.
Wholesale sales should include water sold to another utility for a resale to the public for
hmnan consumption.
Unaccounted-for water is the difference between water diverted or treated (as reported in
Section IIIA1) and water delivered (sold) as reported in Section IIA2. Unaccounted-for
water can result from:
1 ) inaccurate or incomplete record keeping;
2) meter error;
3) unmetered uses as fire fighting, line flushing, and water for public buildings and water
treatment plants;
4) leaks; and
5) water theft and unauthorized use.
3. The peak-day to average day ratio is calculated by dividing the maximum daily pumpage
(in million gallons per day) by the average daily pumpage. Average daily pumpage is the
total pumpage for the year (as reported in Section IIAI) divided by 365 and expressed in
million gallons per day.
4. Municipal per capita use is defined as total municipal water use dividing by the population
and the 365 days. Total municipal water use is calculated by subtracting the industrial sales
and wholesale sales from the total water diverted or treated (as reported in Section IIA1).
Total municipal water use = total water diverted or treated industrial sales wholesale sales
Municipal per capita use (gpcd) = total municipal water use/population/365.
Note: The AWWA considers the municipal per capita use as the most representative figure
to use in long-range water supply and conservation planning.
Seasonal water use is the difference between base (winter) daily per capita use and summer
daily per capita use. To calculate the base daily per capita use, average the monthly
diversions for December, January and February and divide this average by 30. Then divide
this figure by the population. To calculate the summer daily per capita use, use the months
of June, July and August.

APPENDIX C2
Estimating the Technical Potential for Reducing Per Capita Water Use
The technical potential for reducing pcr capita water use is the range in potential water savings
that can be achieved by implementing specific water conservation measures. The bottom of the
range represents the potential savings under a "most likely," or real-world conservation scenario.
The top of the range represents the potential savings under an "advanced" conservation scenario.
The conservation measures include:
reducing unaccounted-for water uses;
reducing indoor water use due to watcr-conserving plumbing fixtures;
reducing seasonal water use; and
reducing water use through public education programs.
Guidelines and examples for calculating the technical potential water savings for each of these
conservation measures are given below.
1. Reducing Unaccounted-For Water Uses
The TCEQ considers unaccounted-for water uses of 15% or less as acceptable for
communities serving more than 5,000 people. Smaller, older systems or systems that have a
larger service area may legitimately experience larger losses. Losses above 15% may be an
area of concern, and provide a conservation potential.
The bottom of the range for technical potential savings for unaccounted-for uses is zero. To
calculate the top of the range, see the following example:
Example
Unaccounted-for uses
19.50% (App C, II.A.3)
_Dry-year per capita water use - 250 gpcd (App C, VI.C.3)
Potential for reduction in unaccounted-for use
=(250gpcdx 19.5%) (250gpcdx15%)
- 48.75 gpcd 37.5 gpcd
= 11.25 gpcd
Technical Potential Savings Range = 0 to 11.25 gpcd
Page 53 of 60
Computation for Coppell with goal of 8% unaccounted water loss:
Unaccounted-for uses - 9.85
Dry-year per capita water use - 226
Potential for reduction in unaccounted-for use
(226x9.85%) (226x8%) 4.2 gpcd
Technical Potential Savings Range = 0 to 4.2 gpcd
II. Reducing Indoor Water Use due to Water-Conserving Plumbing Fixtures
The Texas Water Development Board (TWDB) recently completed a water conservation
study that estimated that the average savings of replacing higher water-use fixtures with more
efficient fixtures mandated by state and federal laws would be 16 gallons per person per day
(10.5 gpcd for toilets and 5.5 gpcd for showerheads). The TWDB used 1995 as their
benchmark for determining the potential average per-capita water savings of an entity. The
1995 population was assumed to have less-efficient water fixtures. No additional water
savings can be expected in the basis of fixture replacement for the post-1995 population. By
1995, retailers were assumed to have sold off their remaining stock of high water use
plumbing fixtures. The annual rate of replacement was estimated to be 2% of the 1995
population.
The TWDB Estimated the water savings due to low-flow plumbing fixture replacements as
follows:
PCS2000 (((POP1995 x 10%) + G1995-00) / POP2000) x 16 gpcd
PCS2000- (((26600 x 10%) + 9350 / 35950) x 16 gpcd
GPCD 1995 = PCS2000+GPCD2000
231.35 - 5.35 + 226
Where:
GPCD2000 Per person, per day in the Year 2000 (gpcd) 226
Gl 995-00 Population growth between 1995 an d2000 9350
PCS2000 The entity's average gpcd savings due to
plumbing code changes (fixture replacement)
between 1995 and 2000 5.35
PCS2010 The entity's average gpcd savings in 2010
due to plumbing code changes (fixture replacement)
in the previous 10 years
POP 1995 July 1995 population estimate 26,600
POP2000 Census 2000 population (cities) or
Year 2000 population estimate 35,950
0902010- Population projections for the entity in the decades
POP2060 2010 through 2060
Page 54 of 60
The remaining savings was calculated as follows:
PCS2010 = [((POP1995 x 30%) + (POP2010 POP1995))/POP2010 x 16 gpcd} - PCSD2000
GPCD2010 - GPCD2000 - PCS2010
(26600 x 30%) + (39700-26600)) / 39700) 16 - 5.35 = 3.15
226- 3.15 = 222.85
Note: These formulas work through 2040. By 2050, all of the fixture replacements would have
taken place and no additional savings would occur.
(26600 x .35) (39700-26600) / 39700) 16 - 5.35 = 3.68
226 - 4 = 222
IlL Reducing Seasonal Water Use
The Texas Water Development Board (TWDB) has calculated seasonal use as a percentage
of average annual per capita use for East Texas (20%), West Texas (25%), and a statewide
average of 22.5% Seasonal water use is calculated by multiplying the average annual per
capita use in gpcd by the appropriate percentage.
The technical potential for reduction in seasonal use is then calculated by multiplying the
seasonal use by 7% for the "most likely" conservation scenario, and by 20% for the
"advanced" scenario. Below is an example calculation:
Example:
Average annual dry-year per capita use - 185 gpcd
Geographical location - West Texas
Seasonal use = (185 gpcd x 25%) = 46.25 gpcd
Potential reduction in seasonal use (Most Likely scenario) = (46.25 x 7%) = 3.24 gpcd
Potential reduction in seasonal use (Advanced scenario) = (46.25 x 20%) = 9.25 gpcd
Technical Potential Savings Range = 3.24 to 9.25 gpcd
Page 55 of 60
Computation for Coppell:
Average annual dry-year per capita use = 228 gpcd
Geographical location - North Texas
Seasonal use -- 228 x .225= 51.3 gpcd
Potential reduction in seasonal use (Most Likely scenario) = 3.6 gpcd
Potential reduction in seasonal use (Advanced scenario) 10.3 gpcd
Technical Potential Savings Range = 3.6 to 10.3 gpcd
IV. Reducing Water Use through Public Education and Water Rates Programs
The technical potential for water conservation from public education and water rates
programs is estimated to be from 2% of the average annual per capita use for the "most
likely" conservation scenario to 5% for the "advanced" scenario, according to the "Water
Conservation Guidebook," published n 1993 by the American Water Works Association.
Below is an example calculation:
Example:
Average annual per capita use = 185 gpcd
Potential reduction in water use (Most Likely scenario) = (185 x 2%) - 3.70 gpcd
Potential reduction in water use (Advanced scenario) = (185 x 5%) -- 9.25 gpcd
Technical Potential Savings Range = 3.7 to 9.25 gpcd
Computation for Coppell:
Average annuaI per capita use - 228 gpcd
Potential reduction in water use (Most Likely scenario) = (228 x 2%) = 4.5 gpcd
Potential reduction in water use (Advanced scenario) (185 x 5%) -- 11.4 gpcd
Technical Potential Savings Range = 4.8 to 11.4 gpcd
To calculate the total technical potential for reducing municipal per capita water use, simply
add the individual technical potential amounts calculated in items l-IV above. In this case
the total technical potential range equals 6.94 gpcd to 29.75 gpcd.

Total Technical Potential Savings 11.2 to 28.9 g-pcd
To calculate the long-run planning goal, subtract these totals from the dry-year water demand.
Example:
i Long-run planning goal = (dry year water demand with low-flow fixtures) minus total technical potential)
- 250 gpcd 6.94 gpcd - 243 gpcd ("most likely" scenario)
= 250 gpcd - 29.75 gpcd - 220 gpcd ("advanced" scenario)
Long-run planning goal for municipal water use = 243 gpcd to 220 gpcd
Computation for Coppell:
Long-run planning goal - (dry year water demand with low-flow fixtures) minus total technical potential)
5-year 217 ("most likely" scenario)
199 ("advanced" scenario)
