1. INTRODUCTION AND OBJECTIVES
Water supply has always been a key issue in the development of Texas. In recent years,the
growing population and economic development of North Central Texas have led to
increasing demands for water supplies. 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. It is therefore important that we make efficient use of
our 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 plans for public water suppliers 1. TCEQ guidelines and
requirements are included in Appendix B. The North Texas Municipal Water District
(NTMWD) has also developed this water conservation plan for its member cities and
�., . customers following TCEQ guidelines and requirements.
The objectives of this water conservation plan are as follows:
• To reduce water consumption from the levels that would prevail without
conservation efforts.
ir..
• To reduce the loss and waste of water.
• To improve efficiency in the use of water.
• To document the level of recycling and reuse in the water supply.
• To extend the life of current water supplies by reducing the rate of growth in
demand.
In order to adopt this plan,NTMWD requires the Town of Prosper to do the following:
• Complete the water utility profile(provided in Appendix C).
• Set five- and ten-year goals for per capita water use.
• Adopt ordinance(s)or regulation(s) approving the plan.

( 4. SPECIFICATION OF WATER CONSERVATION GOALS
Current TCEQ rules require the adoption of specific water conservation goals for a water
conservation plan. As part of plan adoption, each member city and customer will develop 5-
year and 10-year goals for per capita municipal use, following TCEQ procedures described
in the water utility profile (Appendix C). These goals should be submitted to NTMWD in
draft form for review. The goals for this water conservation plan include the following:
• Keep the per capita municipal water use below the specified amount in gallons per
capita per day in a dry year,to be shown on the completed Table C-1 (5-year and 10-
year goals).
• Keep the level of unaccounted water in the system below 12% annually in 2008 and
subsequent years, as discussed in Section 5.4.
• Implement and maintain a program of universal metering and meter replacement and
repair, as discussed in Section 5.2.
• Decrease waste in lawn irrigation by implementation and enforcement of landscape
water management regulations, as discussed in Section 8.4.
• Raise public awareness of water conservation and encourage responsible public
behavior by a public education and information program, as discussed in Section 6.
• Develop a system specific strategy to conserve water during peak demands, thereby
reducing the peak use.

( 5. METERING, WATER USE RECORDS, CONTROL OF UNACCOUNTED
WATER,AND LEAK DETECTION AND REPAIR
One of the key elements in water conservation is careful tracking of water use and control of
losses through illegal diversions and leaks. 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.
5.1 Accurate Metering of Treated Water Deliveries from NTMWD
NTMWD supplies all of the water used by its member cities and customers. Water
deliveries are metered by NTMWD using meters with accuracy of±2%. These meters are
calibrated on a monthly basis by NTMWD to maintain the required accuracy.
5.2 Metering of Customer and Public Uses and Meter Testing,Repair,and
Replacement
All customers of member cities and customers, including public and governmental users,
should be metered. In many cases, member cities and customers already meter all of their
water users. For those member cities and customers who do not currently meter all of their
water uses, these entities will implement a program to meter all water uses within the next
three years.
Most member cities and customers test and replace their customer meters on a regular basis.
All customer meters should be replaced on a 15-year cycle. Those who do not currently
have a meter testing and replacement program will implement such a program over the next
three years.
5.3 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,allows for the separation of water sales and uses into residential,
commercial, public/institutional, and industrial categories. This information will be
included in an annual water conservation report,as described in Section 5.6 below.
For those entities whose record management systems do not currently allow for the
separation of water sales as described above, they will move to implement such a system
• within the next five years.
5.4 Determination and Control of Unaccounted Water
Unaccounted water is the difference between water delivered to member cities and
customers- from NTMWD and metered deliveries to customers plus authorized but
unmetered uses. (Authorized but unmetered uses would include use for fire fighting,
releases for flushing of lines, and uses associated with new construction.) Unaccounted
water can include several categories:
5-1
Water Conservation Plan Town of Prosper
• Inaccuracies in customer meters. (Customer meters tend to run more slowly as they
age and under-report actual use.)
• Accounts which are being used but have not yet been added to the billing system.
• Losses due to water main breaks and leaks in the water distribution system.
• Losses due to illegal connections and theft. (Illegal Water Connections and Theft of
Water Ordinance)
• Other.
Measures to control unaccounted water are part of the routine operations of member cities
and customers. Maintenance crews and personnel are asked to look for and report evidence
of leaks in the water distribution system. The leak detection and repair program is described
in Section 5.5 below. Meter readers are asked to watch for and report signs of illegal
connections,so they can be addressed quickly.
Unaccounted water is to be calculated in Appendix C. With the measures described in this
plan, member cities and customers intend to maintain the unaccounted water below 12% in
2008 and subsequent years. If unaccounted water exceeds this goal, the member city or
customer will implement a more intensive audit to determine the source(s) of and reduce the
unaccounted water. The annual conservation report described below is the primary tool
used to monitor unaccounted water.
5.5 Leak Detection and Repair
As described above, city crews and personnel are asked to look for and report evidence of
leaks in the water distribution system. Areas of the water distribution system in which
numerous leaks and line breaks occur are targeted for replacement as funds are available.
5.6 Monitoring of Effectiveness and Efficiency-Annual Water Conservation
Report .
Appendix D is a form that will be used in the development of an annual water conservation
report for member cities and customers. This form will be completed by March 31 of the
following year and will be used to monitor the effectiveness and efficiency of the water
conservation program and to plan conservation-related activities for the next year. The form
records the water use by category, per capita municipal use, and unaccounted water for the
current year and compares them to historical values. The annual water conservation report
will also be sent to NTMWD,which will monitor regional water conservation trends.
5-2
Water Conservation Plan Town of Prosper
( 6. CONTINUING PUBLIC EDUCATION AND INFORMATION CAMPAIGN
The continuing public education and information campaign on water conservation includes
the following elements:
• Insert water conservation information with water bills. Inserts will include material
developed by member cities' and customers' 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.
• Notify local organizations, schools, and civic groups that member city or customer
staff and staff of the NTMWD are available to make presentations on the importance
of water conservation and ways to save water.
• Make the Texas Smartscape CD, water conservation brochures, and other water
conservation materials available to the public at Town Hall and other public places.
• Make information on water conservation available on the Town of Prosper web site
and include links to the Texas Smartscape website and to information on water
conservation on the TWDB and TCEQ web sites.
As a regional water supplier, the NTMWD has made the "Learning to Be Water Wise"
educational materials for 5th grade students available to local school districts. This program
contains individual kits and activities to educate students on the importance of water and
water conservation activities in the community and in their homes.
•

Water Conservation Plan Town of Prosper
7. WATER RATE STRUCTURE
Member cities and customers will adopt, if they have not already done so, an increasing
block rate water structure that is intended to encourage water conservation and discourage
excessive use and waste of water upon completion of the next rate study or within five
years. An example water rate structure is as follows:
Residential Rates
1. Monthly minimum charge. This can (but does not have to) include up to
2,000 gallons water use with no additional charge.
2. Base charge per 1,000 gallons up to the approximate average residential use.
3. 2nd tier (from the average to 2 times the approximate average) at 1.25 to 2.0
times the base charge.
4. 3rd tier (above 2 times the approximate average) at 1.25 to 2.0 times the 2nd
tier.
5. The residential rate can also include a lower tier for basic household use up to
4,000 gallons per month or so.
Commercial/Industrial Rates
Commercial/industrial rates should include at least 2 tiers, with rates for the 2nd tier at
( 1.25 to 2.0 times the first tier. Higher water rates for commercial irrigation use are
encouraged,but not required.
The Town of Prosper's Water Rates are based on the Water Rate Structure Ordinance as it
currently exists or may be amended.

8. OTHER WATER CONSERVATION MEASURES
8.1 NTMWD Reservoir System Operation Plan
Member cities and customers of NTMWD purchase treated water from NTMWD and do
not have surface water supplies for which to implement a reservoir system operation plan.
NTMWD's permits do allow some coordinated operation of its reservoirs, and NTMWD is
seeking additional water rights for coordinated operation to optimize its available water
supplies.
8.2 Reuse and Recycling of Wastewater
Most member cities and customers do not own and operate their own wastewater treatment
plants. Their wastewater is treated by NTMWD. NTMWD currently has the largest
wastewater reuse program in the state. NTMWD has water rights allowing reuse of up to
35,941 acre-feet per year of treated wastewater for municipal purposes, which provides
about 13 percent of NTMWD's total water supply. NTMWD is currently seeking a permit
that would double its permitted reuse and is also considering additional reuse projects to
increase this supply further. NTMWD also makes treated wastewater from its plants
available for direct reuse for landscape irrigation and industrial use.
For those member cities and customers who do own and operate their own wastewater
treatment plants, they will move toward reusing treated effluent for irrigation purposes
around their plants over the next three years. These entities will also seek other alternatives
for reuse of recycled wastewater.
8.3 Ordinances,Plumbing Codes,or Rules on Water-Conserving Fixtures
The State of Texas has required water-conserving fixtures in new construction and
renovations since 1992. The state standards call for flows of no more than 2.5 gallons per
minute (gpm) for faucets, 3.0 gpm for showerheads, and 1.6 gallons per flush for toilets.
Similar standards are now required nationally under federal law. These state and federal
standards assure that all new construction and renovations will use water-conserving
fixtures.
8.4 Landscape Water Management Regulations
Appendix E is a summary of landscape water management regulations adopted as part of
this water conservation plan. These regulations are intended to minimize waste in landscape
irrigation.
8.5 Additional Water Conservation Incentive Programs (Voluntary)
The Town of Prosper will consider adopting additional water conservation
programs including but not limited to:
• Low-flow toilet replacement and rebate programs,
8-1
Water Conservation Plan Town of Prosper
■ Pressure reduction in the system or for individual customers,
• Rebates for rain/freeze sensors,
• Low-flow showerhead and sink aerators replacement programs, or
■ Other water conservation incentive programs.
8.6 Requirement for Water Conservation Plans by Wholesale Customers
Every contract for the wholesale sale of water by member cities and/or customers that is
entered into,renewed, or extended after the adoption of this water conservation and drought
contingency plan will include a requirement that the wholesale customer and any wholesale
customers of that 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. The requirement will also extend to each successive wholesale
customer in the resale of the water.
8.7 Coordination with Regional Water Planning Group and NTMWD
The Town of Prosper will send a copy of their draft ordinance(s) or regulation(s)
implementing the plan and their water utility profile to the NTMWD for review and
comment. The adopted ordinance(s) or regulation(s) and the adopted water utility profile
will also be sent to NTMWD.

9. IMPLEMENTATION AND ENFORCEMENT OF THE WATER
CONSERVATION PLAN
The Water Conservation Plan Ordinance includes the implementation and enforcement of
the plan including designation of responsible officials to implement and enforce the water
conservation plan. Appendix E, the landscape water management regulations, also includes
information about enforcement. The Town of Prosper is adopting an ordinance related to
illegal connections and water theft.

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 shall
provide information, where applicable, in response to the following.
(1) Minimum requirements. All water conservation plans for municipal uses by public
drinking water suppliers shall include the following elements:
(A) a utility profile including, but not limited to, information regarding population
and customer data, water use data, water supply system data, and wastewater
system data;
(B) specification of conservation goals including, but not limited to,municipal per
capita water use goals, the basis for the development of such goals, and a time
( frame for achieving the specified goals;
(C)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;
(D) a program for universal metering of both customer and public uses of water,
for meter testing and repair, acid for periodic meter replacement;
(E) measures to determine and control unaccounted-for uses of water(for
example,periodic visual inspections along distribution lines; annual or
monthly audit of the water system to determine illegal connections,
abandoned services, etc.);
(F) a program of continuing public education and information regarding water
conservation;
(G) 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;
(H) 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
(I) a means of implementation and enforcement which shall be evidenced by:

VI. CONSERVATION GOALS
Please use the data provided in this survey to establish conservation goals
(additional data may be used).
A. 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.
B. 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.
C. Complete the following in gallons per capita per day(gpcd)to quantify the water
conservation goals for the utility's service area:
1. Estimation of the technical potential for reducing per,capita water use(See Appendix C2).

Definitions of Utility Profile Terms
1. 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
human consumption.
2. 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 such as firefighting, 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 IIA1) divided by 365 and expressed in
million gallons per day.
4. Municipal per capita use is defined as pal annual municipal water use divided by the
population and 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 IIA 1)
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.
5. 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, average the
months of June, July, and August, and divide the average by 31. Then divide the summer
value by the population.

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 lower end 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% (App C,II.A.3)
Dry-year per capita water use= 20 gpcd (App C,II.A.5)
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
Computation for: 2000-2004
Unaccounted-for uses= 0.62% (App C,II.A.3)
Dry-year per capita water use= 145 gpcd (App C,II.A.5)
Potential for reduction in unaccounted-for use
0
Technical Potential Savings Range=0 to 0 gpcd
C2-1
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 population growth
after 1995. 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
where: GPCD2000 Per person,per day in the Year 2000 (gpcd)
G1995-00 Population growth between 1995 and 2000
The entity's average gpcd savings due to plumbing code changes(fixture
PCS2000 replacement)between 1995 and 2000
The entity's average gpcd savings in 2010 due to plumbing code changes
PCS2010 (fixture replacement) in the previous 10 years
(/ POP1995 July 1995 population estimate
POP2000 Census 2000 population(cities)or Year 2000 population estimate
POP2010-
POP2060 Population projections for the entity in the decades 2010 through 2060
The additional savings by decade can be calculated as follows:
PCS2010= [((POP1995 x 30%)+(POP2010-POP1995))/POP2010 x 16 gpcd] -PCS2000
GPCD2010=GPCD2000-PCS2010
Notes: The 30%represents 2%x the number of years (2010-1995). These formulas work through 2040.
By 2050, all of the fixture replacements would have taken place and no additional savings would occur.
The TWDB reductions are included in Table C-1.
C2-2
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.
Based on the TWDB methodology,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 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
Computation for: 2000-2004
Average annual per capita use= 140 gpcd
Geographical location= North Texas
Seasonal use= 31.41 gpcd
Potential reduction in seasonal use(Most Likely scenario)= 2.20 gpcd
Potential reduction in seasonal use(Advanced scenario)= 6.28 gpcd
Technical Potential Savings Range=2.2 to 6.28 gpcd
IV. Reducing Water Use through Public Education and Water Rates Programs
The technical potential for water conservation from public education and wate rates programs is estimated to
be from 2% of the average annual per capita uffe for the "most likely" conservation scenario to 5%for the
"advanced"scenario, according to the "Water Conservation Guidebook,"published in 1993 by the American
Water Works Association. Belqw 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: 2000-2004
Average annual per capita use= 139.59 gpcd
Potential reduction in water use(Most Likely scenario)=(185 x 2%)= 2.79 gpcd
Potential reduction in water use(Advanced scenario)=(185 x 5%)= 6.98 gpcd
Technical Potential Savings Range=2.79 to 6.98 gpcd
C2-3
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 thdotal technical
potential range equals 6.94 aped to 29.75 aped

To calculate the long-run planning goal, subtract these totals from thairy-year water demand
Example:
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: 2000-2004
Long-run planning goal=(dry year water demand with low-flow fixtures)minus(total technical potential)

LANDSCAPE WATER MANAGEMENT REGULATIONS
APPENDIX E
Considerations for Landscape Water Management Regulations
A. Purpose
The purpose of these landscape water management regulations is to provide a
consistent mechanism for preventing the waste of water resources.
B. Lawn and Landscape Irrigation Restrictions
•
1. A person commits an offense if the person irrigates, waters, or knowingly
or recklessly causes or allows the irrigation or watering of any lawn or
landscape located on any property owned, leased, or managed by the
person between the hours of 5:00 a.m. and 8:00 a.m. and between 10:00
a.m. and 6:00 p.m. from June 1 through September 30 of any year.
Systems on well water, reuse or reclaimed water may be exempt from
these restrictions.
2. A person commits an offense if the person knowingly or recklessly
irrigates, waters, or causes or allows the irrigation or watering of lawn or
landscape located on any property owned, leased, or managed by that
person in such a manner that causes:
a. over-watering lawn or landscape, such that a constant stream of
water overflows from the lawn or landscape onto a street or other
drainage area; or
b. irrigating lawn or landscape during any form of precipitation. This
restriction applies,to all forms of irrigation, including automatic
sprinkler systems;ipr
c. irrigating lawn or.landscape when the temperature reaches 40
degrees Fahrenheit or below. This restriction applies to all forms of
irrigation, including automatic sprinkler systems; or
d. the irrigation of impervious surfaces or other non-irrigated areas,
wind driven water drift taken into consideration.
3. A person commits an offense if the person knowingly or recklessly
operates a lawn or irrigation system or device on property that the person
owns, leases, or manages that:
a. has broken or missing sprinkler head(s); or
b. has not been properly maintained to prevent the waste of water.
C. Rain and Freeze Sensors
( 1. Any new irrigation system installed on or after June 1, 2005, must be
equipped with rain and freeze sensing devices in compliance with state
E-1
design and installation regulations. Existing irrigation systems must be •
retrofitted with similar rain and freeze sensors within 5 years.
2. A person commits an offense on property owned, leased or managed if the
person:
a. knowingly or recklessly installs or allows the installation of new
irrigation systems in violation of Subsection C.1; or
b. knowingly or recklessly operates or allows the operation of an
irrigation system that does not comply with Subsection C.1; or
c. fails to repair or replace a broken or missing rain/freeze sensor
within 30 days.
D. Pressure Regulating Devices
1. Any new irrigation system installed on or after June 1, 2005, must be
equipped with one or any combination of the following devices;
a. each zone must be equipped with a pressure regulating valve; or
b. the entire system must utilize pressure regulating nozzles; or
c. the entire system must utilize pressure regulating spray heads
and/or rotors.
( All devices must be in compliance with the state design and installation
regulations.
E. Modifications
1. In special cases, modifications to the requirements of this Appendix E may
be granted by the Town Administrator or his/her designee, to persons
demonstrating extreme hardship or need. Modifications may be granted
under the following circumstances:
a. the applicant must sign a compliance agreement agreeing to
irrigate or water the lawn and/or landscape only in the amount and
manner permitted by the variance; and
b. the variance must not cause an immediate significant reduction to
the water supply; and
c. the extreme hardship or need requiring the variance must relate to .
the health, safety, or welfare of the person making the request; and
d. the health, safety, and welfare of the public and the person making
the request must not be adversely affected by the requested
variance.
E-2
2. An approved modification will be revoked by the Town Administrator, or
his/her designee,upon a finding that:
a. the applicant can no longer demonstrate extreme hardship or need;
or
b. the terms of the compliance agreement are violated; or
c. the health, safety, or welfare of the public or other persons requires
revocation.
