Water Conservation Plan
for the City of The Colony Water Utilities
1.0 Introduction
The Colony Water Utilities is a retail provider of water in The Colony that currently serves over
40 Thousand people within a 16 square mile service area.
The Colony has actively procured water supplies from Dallas Water Utilities, Plano Water
Utilities and developed well water treatment facilities which make it possible for The Colony to
provide water to its customers. In Calendar Year (CY) 2013, The Colony delivered over 1.4
billion gallons of treated water. As the population grows demand for service increase and in order
to meet demand The Colony must plan for increasing the available water supply and expanding
its transmission, treatment, and distribution facilities. The Colony considers water conservation
an integral part of this planning process.
The City has had a water conservation program since the late 1990's. In 2009,The Colony
increased its conservation efforts with the amendment of"Chapter 12 MUNICIPAL UTILITIES
AND SERVICES,"of The Colony Code of Ordinances to include,CONSERVATION
MEASURES RELATING TO LAWN AND LANDSCAPE IRRIGATION.
1.1 State of Texas Requirements
The Texas Administrative Code Title 30, Chapter 288 (30 TAC § 288) requires holders of an
existing permit, certified filing, or certificate of adjudication for the appropriation of surface
water in the amount of 1,000 acre-feet a year or more for municipal, industrial, and other non-
irrigation uses to develop, submit, and implement a water conservation plan and to update it
according to a specified schedule. As such, the City is subject to this requirement. Because the
City provides water as a municipal public water supplier, the City's Water Conservation Plan
must include information necessary to comply with Texas Commission on Environmental Quality
(TCEQ)requirements for each of these designations.'
The requirements of Subchapter A that must be included in the City of The Colony's Water
Conservation Plan are summarized below.
Minimum Requirements for Municipal Public and Wholesale Water Suppliers

desegregation of water sales and uses into the following user classes (residential;
commercial;public and institutional and industrial). (Sections 5.4 and 5.14)
• Requirements for Wholesale Customers: The plan must include 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 30 TAC § 288. 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 30 TAC § 288. (Section 5.9)
• Additional Conservation Strategies: TCEQ Rules also list additional optional but not
required conservation strategies which may be adopted by suppliers. The following
optional strategies are included in this plan:
o Conservation-Oriented Water Rates. (Section 5.8 and Appendix A) and water
rate structures such as uniform or increasing block rate schedules, and/or
seasonal rates,but not flat rate or decreasing block rates;
o Ordinances, Plumbing Codes and/or Rules on Water Conservation Fixtures.
(Section 5.14)
o Fixture Replacement Incentive Programs. (Sections 5.7.1 through 5.7.3)
o Reuse and/or Recycling of Wastewater and/or Gray Water. (Sections 5.16
through 5.16.3)
o Ordinance and/or Programs for Landscape Water Management (Sections 5.5.4
and 5.14).
o Method for Monitoring the Effectiveness of the Plan.
This Water Conservation Plan sets forth a program of long-term measures under which the City
of The Colony can improve the overall efficiency of water use and conserve its water resources.
Short-term measures which respond to specific water management conditions (i.e., periods of
drought, unusually high water demands, unforeseen equipment or system failure, or
contamination of a water supply source) are described in the City of The Colony Drought
Contingency Plan.
2.0 Water Conservation Planning Goals
The objective of this Water Conservation Plan is to achieve efficient use of water through
practices and measures that reduce water consumption and water losses and increase water reuse.
Meeting this objective will allow the use of available water supplies and existing infrastructure to
be extended into the future.
2.1 Benefits of Water Conservation
A well-designed Water Conservation Plan will not deprive the community of essential water uses;
rather, it will provide a blueprint for efficient water use. The benefits of water conservation not
only include those derived from avoided costs, but also others that may not be as easily
City of The Colony Water Conservation Plan

Cin 6s to IaL
enumerated in terms of dollars yet hold significant importance to the City in terms of value.
Benefits of water conservation include:
• Delays the need to develop expensive future water supplies. Costs associated with
developing new water supplies (or purchasing new water) are numerous. These can
include capital costs for construction of pumping facilities, pipelines, water wells, water
storage, and related facilities; costs of obtaining permits; and operational costs such as
labor, energy,and chemicals.
• Extends the life of existing water supplies and infrastructure. Pressures within the water
system will increase in localized areas in order to meet increasing customer demands.
Increased pressures within an aging infrastructure will mean more leaks from the system.
When water demands are maintained or reduced through conservation, higher system
pressure is avoided.
• Reduces peak requirements. A water system is sized to meet its customers' peak
demands. When these peak demands are reduced through water conservation, a portion of
the system's capacity is freed-up for other water customers. This, in effect, increases the
base capacity of the system.
• Lowers capital and operating costs of the existing system. The need for expanding the
water treatment and distribution system is delayed or avoided. Operational costs, such as
power and chemicals,are also reduced.
Other benefits include the generation of positive environmental effects, improving customer good
will and promoting a positive image for The City of The Colony.
2.2 The City's Water Conservation Planning Goals
Listed below are many of the planning goals considered important during the water conservation
planning process:
• Reduce seasonal peak demands
• Reduce water loss and waste
• Decrease consumption measured as gallons per capita per day(GPCD)
• Maintain quality of life
• Allow continued economic growth and development
• Maintain a heightened public awareness of water conservation in The Colony
• "Lead by example" by upgrading city facilities with water efficient fixtures, landscapes,
and irrigation systems wherever possible
• Facilitate regional conservation efforts among neighboring municipalities
• Establish the foundation for continuation of water savings targets for the following five-
year period
• Remain consistent with the Region C Water Plan
City of The Colony Water Conservation Plan

THE
NY
Cin'hpth,InL
• Incorporate, to the extent practicable, measures identified in the Texas Water
Development Board's(TWDB's)best management practices (BMP) Guide.
2.3 Quantified Five- and Ten-Year Goals for Water Savings
Specific elements of the Water Conservation Plan, including planned initiatives, are described in
Section 5.0. The development of the planned initiatives involved the identification and
examination of numerous conservation strategies. These strategies were derived from several
sources, including state agency directives, regional water planning groups, water conservation
literature, water conservation programs used by other municipalities, and the City's existing
Water Master Plan.
Targeted water savings are based on the planned BMPs, historical water use patterns, literature
values, and experience with other utilities. Savings include the combined efforts of all program
elements and the components thereof.

4.0 Description of The Colony Water System
The City has supplied water to meet the needs of The Colony since 1985. Through a complex
system of Transmission Lines, Treatment, and Distribution Facilities and Recycled water
projects, existing are also components of the City water system.
4.1 Water Supply Sources
The City has five water wells, strategically located in the system. The systems design corresponds
to the city's overall water treatment system infrastructure,which includes the Office Creek Pump
Station where purchased water from(DWU) and well water from the City's water well are stored
before being delivered to the distribution system. The Wynnwood Pump Station is located in the
(Tribute) area. Plano Water Utility supplies water to The Colony along Windhaven PKWY East
of the BNSF railroad. All together The Colony has a total of five Pump Stations and a series of
water wells. Water wells are located at Pump Station #1 at 5033 Clover Valley with two water
wells, Pump Station#2 located at 6809 Main St. with one water well, Pump Station#3 located at
5572 North Colony with one water well and Office Creek Pump Station located at 4180 Main St.

4.2 Treated Water Storage and Distribution Systems
The City distribution system is divided into three pressure zones Central, North West (Tribute),
South East (Austin Ranch) with several intermediate areas of service supplied via inline boosters
and pressure reducing valves. Each pressure zone includes one or more ground or elevated
storage tanks that are designed to act both as pressure equalizers and fire protection storage
within the area.
Treated water is pumped into the distribution system from one of the 5 pump stations. Transfers
from pump stations are accomplished by means of"high service" pumps that are located at the
stations in the distribution system. These "high service" pumps are supplied directly from the
pump station clear wells or ground storage tanks. There are a combined total of 5 pump stations,
4 clear wells, 3 ground storage reservoirs,and 3 elevated storage tanks in the distribution system.
The clear wells have a combined storage capacity of 2.4 MG; the ground storage reservoirs and
elevated storage tanks have a total 7 MG and 2 MG, respectively. The combined storage capacity
of the system is approximately 11.4 MG.
The water distribution system consists of approximately 197.3 linear miles of pipe. The capacity
of the treated water distribution system is constantly being upgraded and re-assessed to improve
the ability of the distribution system to meet customers' needs and to replace aging infrastructure.
4.3 Wastewater Treatment Plants
The City of The Colony operates one wastewater treatment plant (WWTP) — Stewart
Creek WWTP - that serves The City of The Colony. The WWTP has an annual average
flow permitted capacity of 3.39MGD with a 7.45 MGD 2-hour peak. A general
description of the plant is as follows:
• Stewart Creek WWTP is currently rated at 3.39 MGD capacity and is located 3
miles North of SH 121 in The City of The Colony. It consists of one influent pump
station, one primary head works with two parallel fine screens and two parallel
grit chambers, two parallel biological aeration treatment trains, four parallel
secondary clarifiers, four parallel cloth disk filters, two parallel channels with
three modules each of Ultra Violet disinfection lamps, and one reuse holding tank
with four reuse pumps. Sludge from the Stewart Creek WWTP is dewatered on
one two-meter belt press and the final solids disposed of in a landfill.
• Stewart Creek WWTP Collection System consists of 203 miles of wastewater
pipes and 9 waste water lift stations.
5.0 The Colony's Water Conservation Program
The City of The Colony has a history of providing guidance in the area of water conservation to
the public. This section provides a description of the city's existing water conservation program
City of The Colony Water Conservation Plan
10
in COLONY
Gn Mlk Ink,
and the enhancements or new conservation measures that are planned to achieve or exceed the
City's stated water conservation goal.
5.1 Accurate Supply Source Metering
The City has a comprehensive program to meter water diverted from supply sources within the
water system. All untreated water diversions to the City of The Colony Well Water Treatment
Plants are metered using Propeller and Mag meters located at the plants.The meters are calibrated
annually in accordance with those standards to an accuracy of plus or minus 5% accuracy per
TCEQ requirements. All untreated water diverted from supply sources is compiled in an annual
Water Report,which shows diversions on a monthly basis.
5.2 Universal Metering, Meter Testing and Repair, and Periodic Meter
Replacement
Universal Metering - The current City ordinance requires metering of all connections, except
closed fire systems with alarms. Individual metering is required at all single-family residential
locations. Most multifamily residential locations, such as apartments and condominiums, have
individual metering for each building or designated water user. Some commercial businesses are
combined through a single master meter as well. Dual metering is currently provided to some
customers based on the individual needs of the user. All treated water pumped from the WTPs is
compiled in an annual Pumped Water Report,which shows water pumped on a monthly basis.
Treated purchased water is metered by Dallas Water Utilities using Venturi meters with rate-of-
flow controllers (ROFCs). Purchased water is metered by the City of Plano using Compound
meters. Raw well and treated water pumped into and from storage tanks is metered using Mag
meters, Propeller meters and Venturi meters. All purchase and well water metered is included in
City of The Colony's Annual Supplied and Pumped Water Report.
Meter Testing and Repair — Meters are tested and calibrated in accordance with AWWA
standards to accuracy within plus or minus 5 percent. The city maintains a program to pull, test,
and replace any meters determined to be functioning outside of these parameters.
Periodic Meter Replacement — Most residential meters are replaced after 1 million gallons.
Repair or replacement of larger general service meters is generally provided at five-year intervals
with annual testing.
5.3 Leak Detection,Repair, and Control of Unaccounted-for Water
The City has an extensive leak detection and repair program and is committed to maintaining the
integrity of the system. Currently, the City has an annual budget of$2.5 million for maintenance
and upkeep of the distribution system. The majority of the budget is used for personnel,
equipment, and materials. Currently approximately 20 employees are employed to operate the
distribution system. Most leaks, illegal connections, or abandoned services are discovered
through the visual observation of field crews or are reported by the public. In 2013 staff
investigated over 350 leaks.
The Leak Detection Program has the goal of surveying the entire water system and improving the
integrity of the water system. The goal is to survey all pipelines annually. Staff members utilize
leak detection equipment, including leak listening devices, meter pressure checks and periodic
water audits for illegal connections or abandoned services. Pressure checks are also performed
City of The Colony Water Conservation Plan
11
�l COLON
CinM th LA
on fire hydrants during flushing and routine exercising. Additionally, pump stations and elevated
tanks levels and system pressures are continuously monitored via the Supervisor Control and
Data Acquisition System(SCADA).
5.4 Monitoring and Record Management of Water Deliveries, Sales and Losses
The City regularly monitors all water flows and sales to both treated and untreated water
customers. All critical data, such as raw well water to WTPs, treated water pumped to
distribution, and unaccounted-for water losses are available on a regular basis, as needed. All
water sources and service connection accounts are individually metered and read on a regular
basis to facilitate accurate comparisons and analysis.
5.5 Continuing Public Education Program
The City recognizes that water conservation is a significant benefit to individuals and
communities in terms of long-term water supply availability and costs. The most readily
available and lowest cost method of promoting water conservation is to inform retail
water users about ways to save water in homes and businesses, in landscaping and lawn
uses, and in recreational uses. The City currently provides the information to public in the
following manner.
5.5.1 Public Awareness
The City provides the public with water conservation pamphlets containing information
on simple easy to follow ways to save water and Water Conservation and Drought
Contingency Plans have been made available to the public. Additionally, this information
is available at kiosks throughout City Facilities, including the lobby of City Hall and
Public Library. Conservation information and City events and environmental program
functions that involve the general public is distributed to new customers Public
information is also available on the City website and other public media outlets supported
by the City. In addition the City conducts educational tours at our facilities to local
students. During the tours students are involved in conversations on water conservation
tips and receive written information that can be practiced at home.
5.6 Non-promotional Water Rate Structure
The City has a conservation-oriented rate structure for customers. Under the increasing block rate
structure, customers are billed a water meter service charge which increases with the size of their
meters. Customers are also billed for water usage, and increasing usage results in a higher unit
cost for water. Connecting higher rates to increased consumption discourages customers from
wasting water. A copy of the City's rates is provided in Appendix A.
5.7 Means to Implement and Enforce the Water Conservation Plan
The City administers and implements various components of the Water Conservation Program
within the City of The Colony as authorized by the City Code of Ordnance, Chapter 12,
Municipal Utility and Services. The enforcement of the water rate structure and metering is
City of The Colony Water Conservation Plan
12
/,CLONy
Citi M d.•Lae
automatic. Water conservation lawn and landscape restrictions are enforced by the Department of
Code Compliance. Water contracts with wholesale suppliers require the City to develop a water
conservation plan to ensure that available supplies are used efficiently.
5.8 Coordination with Regional Water Planning Groups
The City will provide a copy of this Water Conservation Plan to the Region C Water Planning
Group. As a retail water supplier in the region, The City will work with the Regional Water
Planning Group to improve efficient utilization of existing water resources and/or develop new
resources which meet the needs of the region.
5.9 Desegregation of Water Sales by Customer Class
The City separates water customers into three general account classes:
• Residential—The Residential class includes single-family residences.
• Commercial — The Commercial class includes master metered multi-family housing,
master metered apartments, and master metered mobile homes, office buildings,
restaurants,hotels,churches, and other commercial and light industrial customers.
• Institutional — The Institutional class consists of city buildings, parks, fire stations,
libraries.
Based on the average retail water sold within the City of Colony from 2009 -2013, Commercial
and Residential customers account for most of the City's water consumption(Figure 5-1).

3%
5.10 Plumbing Code Ordinances
The State of Texas has placed maximum flow rate requirements on plumbing fixtures. As of
January 1, 2014, the law requires maximum average flow rates of 1.28 gallons per flush(gpf) for
toilets and 0.5 gpf for urinals. Effective October 12, 2013, the City of The Colony amended the

plumbing code by adopting the 2012 Edition of the International Green Construction Code of the
International Code Council,Inc. with specified exceptions.The City code at a minimum complies
with State of Texas requirements.
5.11 Wastewater Reuse and Recycling
The Colony has developed water recycling projects and plans for additional projects, as described
in the following sections: direct reuse projects, indirect reuse projects, and contracts for return
flows into reservoirs.Table 5-1 presents a summary of direct and indirect recycled water projects.

The Colony provides recycled water from the WWTP to the Stone Briar Country Club golf
courses for irrigation.The golf courses currently uses up to 1.7 MGD.
5.11.2 Indirect Reuse Projects
The Colony releases treated wastewater back into the Lake Lewisville Reservoir after it
has been processed through the plant.
5.12 Method to Monitor the Effectiveness of the Plan
The effectiveness and efficiency of the water conservation program will be monitored on an
