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. 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 objectives 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 objectives 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 minimize 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
The 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 rules, 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“A strategy or combination of strategies for reducing the volume of water withdrawn from a water supply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.”
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 water use would be high. Per capita municipal
water use in a year with normal or high precipitation during the summer should be less than projected here.
Table 3.2 2011 Regional Water Plan City Water Demand Projections 2000-2060

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 conservation and drought contingency plan.

The City’s water conservation goals include the following:
Achieve year 2020 per capita municipal water use of 212 gpcd or less, as shown in Table 3.3. This
represents a reduction of 22 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 2025 per capita municipal water use of 210 gpcd or less, as shown in Table 3.3. This
represents a reduction of 22 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 6 percent in 2015 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%.
3.4Metering of Customer and Public Uses and Meter Testing, Repair, 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 continue to implement a meter replacement
program that will replace every residential meter on a 10-year cycle. Initial efforts will focus on the oldest
meters in the system. The City currently replaces about 1100 meters every year.
In addition, all meter replacements will require an AMR meter with the capability of providing water use
data at a minimum of every 15 minutes. These meters will provide the City the ability to better detect leaks
and provide the citizens a better record of their daily water use. These meters will also help to eliminate
meter read errors.
All meters registering any unusual or questionable readings will be replaced when the irregularity is
noticed, regardless of age.
10
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 loss:
Respond to all 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 1 percent to 9
percent in the last five years. With the measures described in this plan, the City of Coppell intends to
maintain the unaccounted water below 6 percent in 2015 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:
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.
11
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.coppelltx.gov 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 Coppell 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.
Table 3.4 Monthly Meter Base Rate:
Meter Total Meter Total

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 Coppell. 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 funds are available. In fiscal year
2012-13, the City expended over $500,000 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 in pressure.
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.
14
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 facilities,
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
following 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.
6.2Public 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 with 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.
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.

CONTINGENCY PLANS, GUIDELINES AND
REQUIREMENTS
SUBCHAPTER A WATER CONSERVATION PLANS
RULE §288.2 Water Conservation Plans for Municipal Uses by
Public Water Suppliers
(a) A water conservation plan for municipal water use by public water suppliers must provide
information in response to the following. If the plan does not provide information for each
requirement, the public water supplier shall include in the plan an explanation of why the
requirement is not applicable.
(1) Minimum requirements. All water conservation plans for municipal uses by public water
suppliers must include the following elements:
(A) a utility profile in accordance with the Texas Water Use Methodology, including, but not
limited to, information regarding population and customer data, water use data (including total
gallons per capita per day (GPCD) and residential GPCD), water supply system data, and
wastewater system data;
(B) a record management system which allows for the classification of water sales and uses into
the most detailed level of water use data currently available to it, including, if possible, the sectors
listed in clauses (i) - (vi) of this subparagraph. Any new billing system purchased by a public
water supplier must be capable of reporting detailed water use data as described in clauses (i) -
(vi) of this subparagraph:
(i) residential;
(I) single family;
(II) multi-family;
(ii) commercial;
(iii) institutional;
(iv) industrial;
(v) agricultural; and,
(vi) wholesale.
(C) specific, quantified five-year and ten-year targets for water savings to include goals for
water loss programs and goals for municipal use in total GPCD and residential GPCD. The goals
established by a public water supplier under this subparagraph are not enforceable;
(D) metering device(s), within an accuracy of plus or minus 5.0% in order to measure and
account for the amount of water diverted from the source of supply;
(E) a program for universal metering of both customer and public uses of water, for meter
testing and repair, and for periodic meter replacement;
(F) measures to determine and control water loss (for example, periodic visual inspections along
distribution lines; annual or monthly audit of the water system to determine illegal connections;
31
abandoned services; etc.);
(G) a program of continuing public education and information regarding water conservation;
(H) a water rate structure which is not "promotional," i.e., a rate structure which is cost-based
and which does not encourage the excessive use of water;
(I) a reservoir systems operations plan, if applicable, providing for the coordinated operation of
reservoirs owned by the applicant within a common watershed or river basin in order to optimize
available water supplies; and
(J) a means of implementation and enforcement which shall be evidenced by:
(i) a copy of the ordinance, resolution, or tariff indicating official adoption of the water
conservation plan by the water supplier; and
(ii) a description of the authority by which the water supplier will implement and enforce the
conservation plan; and
(K) documentation of coordination with the regional water planning groups for the service area
of the public water supplier in order to ensure consistency with the appropriate approved regional
water plans.
(2) Additional content requirements. Water conservation plans for municipal uses by public
drinking water suppliers serving a current population of 5,000 or more and/or a projected
population of 5,000 or more within 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;
(B) adoption of ordinances, plumbing codes, and/or rules requiring water-conserving plumbing
fixtures to be installed in new structures and existing structures undergoing substantial
modification or addition;
(C) a program for the replacement or retrofit of water-conserving plumbing fixtures in existing
structures;
(D) reuse and/or recycling of wastewater and/or graywater;
(E) a program for pressure control and/or reduction in the distribution system and/or for
customer connections;
(F) a program and/or ordinance(s) for landscape water management;
(G) a method for monitoring the effectiveness and efficiency of the water conservation plan;
and
(H) any other water conservation practice, method, or technique which the water supplier shows
to be appropriate for achieving the stated goal or goals of the water conservation plan.
(b) A water conservation plan prepared in accordance with 31 TAC §363.15 (relating to Required
32
Water Conservation Plan) of the Texas Water Development Board and substantially meeting the
requirements of this section and other applicable commission rules may be submitted to meet
application requirements in accordance with a memorandum of understanding between the
commission and the Texas Water Development Board.
(c) A public water supplier for municipal use shall review and update its water conservation plan,
as appropriate, based on an assessment of previous five-year and ten-year targets and any other
new or updated information. The public water supplier for municipal use shall review and update
the next revision of its water conservation plan every five years to coincide with the regional water
planning group.

Definitions of Utility Profile Terms
Residential
1. 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
human consumption.
Unaccounted-for water
2. 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.
peak-day to average day ratio
3.The 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 IIA1) divided by 365 and expressed in
million gallons per day.
Municipal per capita use
4. 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
wholesale sales
and 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
5. is the difference between base (winter) daily per capita use and summer
base daily per capita use
daily per capita use. To calculate the , average the monthly
diversions for December, January and February and divide this average by 30. Then divide
summer daily per capita use
this figure by the population. To calculate the , 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 per 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 water-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.
I. 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%
Dry-year per capita water use = 250 gpcd (App C, VI.C.3)
Potential for reduction in unaccounted-for use
= (250 gpcd x 19.5%) – (250 gpcd x 15%)
= 48.75 gpcd – 37.5 gpcd
= 11.25 gpcd
Technical Potential Savings Range = 0 to 11.25 gpcd
Page 46 of 52
Computation for Coppell with goal of 8% unaccounted water loss:
Unaccounted-for uses = 9%
Dry-year per capita water use = 245
Potential for reduction in unaccounted-for use
(245x9%) – (245x4%) = 12.25 gpcd
Technical Potential Savings Range = 0 to 12.25 gpcd
II. Reducing Indoor Water Use due to Water-Conserving Plumbing Fixtures
The Texas Water Development Board (TWDB) 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:
PCS2010 = (((POP1995 x 10%) + G1995-10) / POP2010) x 16 gpcd
PCS2010 = (((26600 x 10%) + 9350 / 38750) x 16 gpcd+4.96
GPCD1995 = PCS2010+GPCD2010
224.96 = 4.96 + 220
Where:
GPCD2010 Per person, per day in the Year 2010 (gpcd) 220
G1995-10 Population growth between 1995 an d2010 12,150
PCS2010 The entity’s average gpcd savings due to
plumbing code changes (fixture replacement)
between 1995 and 2010 4.96
PCS2010 The entity’s average gpcd savings in 2010
due to plumbing code changes (fixture replacement)
in the previous 10 years
POP1995 July 1995 population estimate 26,600
POP2010 Census 2010 population (cities) or
Year 2010 population estimate 38,750
0902010-Population projections for the entity in the decades
POP2060 2010 through 2060
Page 47 of 52
The remaining savings was calculated as follows:
PCS2010 = [((POP1995 x 30%) + (POP2010 – POP1995))/ POP2010 x 16 gpcd} – PCSD2000
GPCD2010 = GPCD2000 – PCS2010
(26600 x 30%) + (38800-26600)) / 38800) 16 – 4.96 = 3.36
225 – 3.36 = 221.64
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)+ (54000-26600) / 54000) 16 – 4.96 = 5.92
225 – 6 = 219
III. 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 48 of 52
Computation for Coppell :
Average annual dry-year per capita use = 229 gpcd
Geographical location = North Texas
Seasonal use = 229 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 annual per capita use = 229 gpcd
Potential reduction in water use (Most Likely scenario) = (229 x 2%) = 4.6 gpcd
Potential reduction in water use (Advanced scenario) = (185 x 5%) = 11.5 gpcd
Technical Potential Savings Range = 4.6 to 11.5 gpcd
To calculate the total technical potential for reducing municipal per capita water use, simply
add the individual technical potential amounts calculated in items I-IV above. In this case
the total technical potential range equals 8.2 gpcd to 37.73 gpcd.
