CHAPTER 1
INTRODUCTION
PURPOSE:
The purpose of this plan is to introduce guidelines necessary to revise the water conservation
plan for Denton residents based upon new criteria introduced by the Texas Natural Resources
Conservation Commission (TNRCC) and The U S Environmental Protection Association
(USEPA) The criteria mandates that water purveyors have a revised conservation plan in effect
by Sept 1, 1999
By reading this report, the reader will gam insight into the implementation of the revisions in a
way that will preserve water as a natural resource This report has information obtained through
research of Texas Water Development Board (TWBD), USEPA, American Waterworks
Association (AWWA) and TNRCC documents This Conservation Plan closely follows the
format established by the TNRCC
The goal of the City is to achieve a minimum overall water consumption per capita reduction of
fifteen percent (15%) by 2050 This decrease in water consumption will effectively reduce water
demands, thereby increasing the service capacity of the water and wastewater systems Another
goal of the plan is to identify situations where unaccounted for water use is occurring This will
determine areas to use water more efficiently throughout the city Internal auditing, leak
detection and external auditing will be used to determine this unaccounted for water
SCOPE -
The City of Denton is located on the North end of a triangle formed by Dallas, Fort Worth and
Denton According to the latest census the City's current population is 74,100 and is mostly
residential homes The City's two water supply reservoirs are Lake Lewisville and Lake Ray
Roberts The Corps of Engineers owns both lakes The City of Dallas began withdrawing water
from Lake Lewisville in 1957 and from Ray Roberts in 1987 Dallas and Denton share Water
Rights and Storage Rights to both lakes Denton receives 4 8165 percent of the 90 2 Million
Gallons Per Day (MGD) firm dependable yield in Lake Lewisville, which provides a 4 34-MGD
water supply Denton has a 26 percent interest in Lake Ray Roberts's firm dependable yield of
76 MGD, which provides Denton with a 19 8-MGD water supply The scope of work for the
water conservation portion of this project includes two primary tasks
❑ Evaluate the existing water conservation program and propose enhancements using
updated demographic and water -use data
o Develop a Water Conservation Plan that complies with Texas Natural Resource
Conservation Commission (TNRCC) requirements
Drought'Conservanon Plan
12/20/99
UTILITY EVALUATION DATA:
According to TNRCC regulations, a method for monitoring the effectiveness and efficiency of
the conservation plan must be in effect Listed below is a summary of data included in the
contingency plan A detailed summary of utility evaluation data is included in Appendix A
❑ A utility profile including information on population and customer data, water use data,
water supply system data and wastewater system data
❑ Specification of conservation goals and a timeframe for their achievement
❑ Metering devices within an accuracy of plus or minus 5% to measure and account for
water diverted from the source of supply
❑ Program for universal metering of both customer and public uses of water, meter testing
and repair and periodic meter replacement
❑ Measures to determine and control unaccounted-for uses of water
❑ Program of continuing public education and information regarding the water conservation
and the drought contingency plan
❑ A water rate structure which is not "promotional' (i e a rate structure which is cost -based
and does not encourage excessive use of water)
❑ A drought management plan
❑ An education and information program revealing notification procedures, trigger
conditions, water -use restrictions, reservoir operations plan, and the means of
implementation and enforcement of the plan
❑ Documentation showing coordination with the Regional Planning Group to insure
consistency with the approved regional water plan
This Water Conservation Plan sets forth a program of long-term measures under which the City
of Denton can improve the overall efficiency of water use and conserve its water resources
Short-term measures, which respond to specific water management conditions such as periods of
drought, unusually high water demands, unforeseen equipment or system failure, or
contamination of a water supply source, are provided in the City of Denton Drought Contingency
Plan
Four planning steps used to develop this Water Conservation Plan are
❑ Conservation goals based on the specific needs of the Denton water system
❑ Population and per capita water demand forecasts were developed
❑ A review and identification of existing conservation measures and enhancements of new
conservation measures
❑ Selection of conservation strategies consistent with the goals
RESPONSIBILITY:
Conservation plan reviews, updates, and training will be coordinated by the Assistant City
Manager of Utilities (ACM/Utilities) An annual review of this plan will update procedures
necessary to notify the public about new conservation initiatives or revisions to the management
plan
Drought/Conservation Plan

CHAPTER 2
WATER CONSERVATION PLAN
20 Benefits of Water Conservation:
The objective of the City of Denton Water Conservation Plan is to achieve efficient use of water
supply resources The goal is to accomplish conservation through practices and measures that
reduce per capita water consumption within the distnbution system and water use by the
customer Meeting this objective will allow extending the use of available water supplies and
existing infrastructure into the future
It should be emphasized that to Denton Water Utilities, conservation means using water wisely
A well -designed Water Conservation Plan will not deprive our community of essential water
uses Rather, it will provide a blueprint for more efficient water use This approach could have
the following benefits
❑ Lower water bills for customers
❑ Control of future water rates
❑ Extended availability and improved protection of water resources
21 Water Conservation Planning Elements -
Elements most critical to the development of a water conservation plan include indoor and
outdoor conservation practices, landscaping practices, and plumbing retrofit installations Other
elements considered in preparing this water conservation plan are
❑ A plan for public education and information
❑ Plumbing code requirements
❑ Plumbing retrofit requirements
❑ A universal metering and meter repair/replacement program
❑ Landscaping, water audits, and leak detection requirements
❑ Recycling and reuse
❑ Plan Implementation
22 Per -Capita Water -Demand Reduction Goal
Frequently, water demand is expressed in terms of "per -capita" use, or the amount of water used
on a per -person per day basis (gpcd) Under this plan, Denton established water conservation
goals to manage per capita use within the per capita water demand projections recommended for
Denton by the TWDB and TNRCC These goals include a 15% reduction in per capita usage
over a 50-yr period as listed in the table below This table lists those water use reductions,
which can be expected for the implementation of water saving plumbing fixtures through the
plumbing code

23 Description of the Denton Water Utilities System
2 3.1 Water Treatment -
Denton has one water treatment plant expanded to a peak treatment capacity of 28 5 MGD in
1989 Peak day water demands determine the capacity of production plant facilities The peak
day is the average flow for the one day of the year that has the highest water consumption
Normally, peak day demand is approximately 2 0 times an average daily use Based on these
cntena, Denton will need additional capacity on line by 2002 to maintain present service levels
A new Lake Ray Roberts Water Treatment Plant will provide 20 MGD to support the anticipated
growth needs of the city The City of Denton acquired a site for the construction of the new
water treatment plant and plans to begin construction during the year 2000
2 3 2 Elevated Storage:
The City of Denton has three elevated storage tanks with a combined capacity of 3 36 Million
Gallons (MG) These include an older 0 36 MG elevated storage tank located on Bell Ave
referred to as the Peach Street Tank The 2 0 MG McKenna standpipe has a 70-foot head range,
but only I 0-MG worth of usable elevated storage capacity The 2 0-MG tank on the north side
of town, just east of the Texas Instruments plant is the last storage tank built in Denton Denton
began withdrawing water from the tank in 1969 The tank is called the High School tank due to
its exterior paint scheme using the Denton High School colors The City plans to add 3 MG in
elevated storage to increase the total volume within in the distribution system The City needs
these tanks to create more storage for the distribution as the new production plant and pump
station go on-line
2 3 3 Ground Water Supply System•
The City currently maintains three wells that produce a combined 2-MGD These wells provide
an emergency source of water during times of stress on the distribution system Due to declining
ground water levels and the age and condition of the wells, staff has not included them in future
plans for the water system
2 3 4 Ground Storage:
Ground storage tanks store treated water for standby reserves, fire protection and maintain
pressure on the distribution system during times of extra demand This provides a margin of
safety for emergency conditions and allows the treatment plant to operate at a steady flow rate
The ground storage tanks also serve as treated supply reservoirs for high service and booster
pumps, which pressurize the distribution system Currently, the city has one 10 MG and three
2 0 MG ground storage reservoirs located at the Lake Lewisville Water Production Plant Three
million gallons of additional ground storage is planned for the initial phase of the Hartlee Field
ground Storage and booster pump station facility due on-line in 2001 The pump station will
serve as a remote ground storage and high service pump station for the new water treatment plant
at Lake Ray Roberts The pump station will have a total capacity of 12 MG and eventually
provide water to the middle and lower pressure planes when it is built -out The City plans to
build additional storage tanks at this site for future expansions of the water supply system
Drought/CQnservanon Plan 12/20/99
24 Continuing Public Education and Information
The public education program concentrates on initial, long term and new customer programs
The City will promote water conservation by informing the public about methods to conserve
water and demonstrate ways to become contributors to the plan Public education through the
news media and advertising is the major objective Additional programs will develop as contact
with schools, church groups, neighborhood groups, and civic clubs continues to grow
INITIAL PROGRAM
The City of Denton has already begun an initial program that includes radio and TV public
service announcements (PSA's), news releases, advertising, informational flyers, bill stuffers,
and school and neighborhood group presentations News releases etc inform the public about
the need for conservation Educational materials and news releases also promote water
conservation by informing water users about ways to save water inside homes through leak
detection, landscaping techniques, and lawn uses The City currently uses the following methods
to inform the public
Informative School Program: This program uses water conservation brochures,
textbook covers with water conservation messages, and packets to show students how to
use water wisely and effectively Teacher workshops, science fair awards, tours of the
Lake Lewisville Water Production Plant, classroom presentations and participation in
special school events round out this program
Advertising Campaign. Advertising in the Denton Record Chronicle (DRC), cable TV
spots, newsletters, the City bulletin board and conservation brochures inserted into utility
bills focus on specific ways to conserve water Emphasis on leak detection, xenscaping,
and conservation measures inside and outside the home are presented as methods to
practice conservation
Media News Releases and Public Service Announcements News releases and
public service announcements to local radio and TV stations and their Web Sites,
newspapers, and other electronic media will stress the importance of conservation during
the spring and summer This program generates a large amount of news media coverage
of conservation techniques and water supply issues TV channel web sites list cities
using water drought plans and the current stage they are on
Speaking Engagements and Community Events. City employee presentations
to environmental groups, garden clubs, senior citizen centers, youth and civic groups help
spread conservation benefits and promote Drinking Water Week during the first week of
May Employee participation in various community events also enhances public
visibility and establishes a personal rapport with customers Strong customer rapport will
ultimately affect water conservation and all other elements needed to build a stronger
utility
Web Site The City will enhance its Web page to include water conservation tips to
strengthen dissemination of information on water conservation programs The Web page
will become an integral part of the water conservation program as it develops
The Utilities Public Communications staff is currently conducting external audits with customers
who request help with high water bills or special knowledge of conservation techniques
Drought/Conservation Plan
12/20/99
The following areas are places in the home or business where water conservation practices can
achieve the best results Appendix B contains the forms used to complete audits in those areas
Bathroom:
❑ Suggest installation of low -flow showerheads that limit the flow from the shower to
less than three gallons per minute
❑ Take short showers and turn the water off while washing and back on again only to
nnse
❑ Take a shower instead of a bath Showers, particularly those with low -flow
showerheads often use less water than taking a bath
❑ Reduce level of bath water by one or two inches if a shower is not available
❑ Shampoo hair in the shower This takes only a little more water than shampooing
during a bath and much less than doing both separately
o When building a new home or remodeling install low -volume flush toilets, that only
uses 16 gallons per flush
❑ Test toilets for leaks Add a few drops of food coloring to the water in the tank, but
do not flush the toilet Watch to see if the coloring appears in the bowl within a few
minutes If this happens, the toilet has a small leak that needs repair
❑ Use a displacement device such as a toilet dam or bag A plastic bottle filled with
stones or water, recapped, and placed in the tank makes an excellent displacement
device These devices reduce the volume of water in the tank of a conventional toilet
and still provide enough water for flushing However, they do not work in low -
volume toilets
❑ Never use the toilet to dispose of cleansing tissues, cigarette butts or trash
❑ Do not use hot water when cold will do This is a waste of energy
❑ When brushing teeth, turn the water off until it is time to nnse
❑ Encourage residents to turn off the water when washing or scrubbing hands and turn
it back on to nnse
❑ Fill the lavatory bowl with hot water when shaving instead of running the hot water
continuously
❑ Install faucet aerators to reduce water flow rates and overall water use
Kitchen
❑ Scrape the dishes clean instead of rinsing them before washing No need to nnse
unless they are heavily soiled
❑ Use a pan of water or use a stopper in the sink for washing and nnsing pots, pans,
dishes and cooking implements, rather than turning on the water each time to rinse
❑ Always run the dishwater with a full load This will save energy, detergent and
money
❑ Use the garbage disposal sparingly or start a compost pile
❑ Keep a container of dnnking water in the refrigerator Running water from the tap
until it is cool is wasteful
❑ Use a small pan of cold water when cleaning vegetables, rather than letting water run
over them
❑ Use only a little water in the pot and put a lid on it for cooking most food This will
save water and make food more nutntious because vitamins and minerals will not be
poured downs the drain with the extra cooking water
Drought/Conservation Plan
12/20/99
❑ Small kitchen savings from not making too much coffee or letting ice cubes melt in a
sink can add up in a year's time
Laundry:
a Wash only a full load when using an automatic washing machine (32 to 59 gallons
are required per load)
❑ Use the lowest water level setting on the washing machine for light or partial loads
Appliances and Plumbing
❑ Check water requirements of various models and brands when considering purchasing
any new appliances Some use less water than others do
❑ Check all water -line connections and faucets for leaks A slow dnp can waste as
much as 170 gallons of water each day, or 5,000 gallons per month, and will add
significantly to the water bill
❑ Repair faucets to correct drips promptly It is easy to do costs very little, and can
mean substantial savings in plumbing and water bills
❑ Check for hidden water leakage such as a leak between the water meter and the
house To check, turn off all indoor and outdoor faucets and water -using appliances
Read the water meter at 10 to 20 minute intervals If it continues to run or turn, a leak
probably exists and needs to be located
❑ Insulate all hot water pipes to reduce the delays experienced while waiting for the
water to "run hot "
❑ Be sure the water heater thermostat is not set too high Extremely hot settings often
wastes water and energy
❑ Use a moisture meter to determine when houseplants need water More plants die
from over-watenng that from being on the dry side
Outdoor Use
❑ Water only when needed Look at the grass, feel the soil, or use a soil moisture meter
to determine when to water
❑ Do not over -water Soil can absorb only so much moisture, and the rest simply runs
off A timer will help, and either a kitchen timer or an alarm clock will do One and
a half inches of water applied once a week will keep most Texas grasses alive and
healthy
❑ Water lawns early in the morning during the hotter months Otherwise, much of the
water used on lawns will simply evaporate
❑ To avoid excessive evaporation, use a sprinkler that produces large drops of water,
rather than a fine mist Sprinklers that send droplets out on a low angle also help
control evaporation
❑ Set automatic sprinkler systems to provide thorough, but infrequent watering Set
pressure regulating devices to design specifications Ram shutoff devices can prevent
watering in the ram
❑ Use drip irrigation systems for bedded plants, trees, or shrubs, or turn soaker hoses
upside down so the holes are on the bottom This will help avoid evaporation
o Water slowly for better absorption, and do not water on windy days
o Condition the soil with mulch or compost before planting grass or flowerbeds so that
water will soak in rather than run off
Drought/C9nservanon Plan
12/20/99
❑ Fertilize lawns at least twice a year for root stimulation, but do not over -fertilize
Grass with a good root system will make better use of less water and is more drought -
tolerant
❑ Trim only %z to'/< of an inch of grass in the summer months because it holds more
moisture
❑ Use a watering can or hand water with the hose in small areas of the lawn that need
more water
❑ Use water -wise plants Choose plants that have low water requirements, are drought -
tolerant, and adept to an area
❑ Consider decorating some areas of the lawn with wood chips, rocks, gravel, or
materials that do not require water Xenscaping is the common reference for this
landscaping and it is becoming more popular
❑ Use a broom to clean sidewalks or driveways instead of the hose
❑ Use a bucket of soapy water and turn on the hose only for rinsing when washing the
family car
LONG TERM PROGRAM
The long-term program includes semi-annual distribution of educational materials and news
releases corresponding to seasonal peak demand periods News releases, bill stuffers and public
service announcements will continue to provide information on how to conserve water,
encourage water conservation and report progress on achieving the City's water conservation
goals Other objectives of a long-term program include
❑ Public Information Classes
❑ Small Business Classes
❑ Adopt -A -Spot for conservation (i a xenscaping)
❑ An annual Home and Garden show sponsored by the City of Denton, local nurseries
and Texas Agriculture Extension Service to promote xenscaping in the local area
NEW CUSTOMER PROGRAM
Material describing the conservation program and other general information is available to new
water customers when they apply for service The City is formulating plans to include this
information in newcomer packets
2.5 Water Conservation Plumbing Code -
The State of Texas has required 2 5 gpm faucets, 3 0 gpm showerheads, and 16 gpf toilets for
new construction since 1992 The City of Denton has adopted a plumbing code based on the
1992 Edition of the Uniform Plumbing Code Denton's code complies with the State of Texas
requirements Below, are the standards for residential and commercial fixtures
• Wall Mounted Flushometer Toilets
• All other Toilets
• Flush valve urinals
• Shower heads
• Lavatory and Kitchen
• Faucets
No more than 2 0 gallons per flush
No more than 16 gallons per flush
No more than 10 gallons per flush
No more than 2 5 gallons per minute
No more than 2 5 gallons per minute
Flow Restricting Type
Drought/Conservation Plan
12/20/99
• All hot water lines
• Swimming pool
26 Plumbing Retrofit Program:
Insulated
New pools must have re -circulating
filtration equipment
The City encourages customers and owners of buildings that do not have water conserving
plumbing devices to retrofit their old fixtures The educational and advertising programs inform
residents of the advantages of installing water saving devices as well as the availability of these
items
2.7 Universal Metering:
The current City of Denton ordinance requires metering of all connections, except closed fire
systems with alarms Individual metenng is required on all single-family residential locations
Some multifamily residential locations, such as apartments and condominiums, have individual
metering, but most are combined through a single master meter per complex Some commercial
businesses are also combined through a single master meter as well Currently, dual metering is
provided to some customers based on their individual needs
28 Meter Testing and Repair:
Meter tracking, repair and replacement, coupled with the ongoing water accounting or auditing is
used in conjunction with other programs such as leak detection and repair to potentially save
significant quantities of water The City of Denton performs annual calibrations for all water
meters greater than 3" is size
29 Periodic Meter Replacement:
The Meter Shop replaces all residential meters at 10-year intervals Repair or replacement of
larger general service meters is accomplished on an as -needed basis The City will also repair or
exchange any meter reported as inaccurate by a water customer
210 Water Audits and Control of Unaccounted-for Water
The City conducts an internal water audit each year to confirm that the water system is free from
excessive leakage This program demonstrates to the public that the utility is very concerned
about the utilities' performance in a conservation program as well as with resident and business
participation
The City is considering expansion of the program to include
1 Commercial Businesses
This would include a site inspection and water audit to discuss water conservation
improvements to the business by retrofitting plumbing fixtures as well as educating
employees on water conservation techniques
Drought/Cgnservauon Plan
12/20/99
2 Industrial sites
Cover industrial sites in much the same way as commercial sites Another aspect that
could be included would be a city -sponsored seminar to discuss industrial and
commercial concerns with management while presenting and sharing ways to
conserve and use water more efficiently
3 Residential homes
Expand the initial on -site education program by showing customers the merits of
retrofitting the inside of older homes with toilet dams, faucet and showerhead water
savers as well as sink aerators or flow restrictors to conserve water
The residential audit program goals include
❑ Estimate the quantity, quality and value of water use, and
❑ Identify cost-effective opportunities to use it more efficiently
To minimize future water problems and costs, all Texans must start now to make efficient
use of water resources The largest saver is the customer A 15% reduction in personal
water use can save water and wastewater ratepayers considerable dollars over the next 50
years
2.11 Rate Structure.
Denton uses an inverted -block rate structure to bill residential customers and discourage
excessive water use during summer months The majority of this water is used for outside
landscape irrigation The inverted block structure charges increasingly higher rates for water
uses above 15,000 gallons per month and above 30,000 gallons per month per connection
The City bills commercial customers on a flat rate structure because their water consumption is
generally consistent throughout the year It is also more difficult to establish an inverted block
rate structure for commercial customers due to the wide range of monthly consumption by
individual commercial customers
2 12 High/Low Billing Procedures:
The purpose of the program is to catch bad meter reads and identify customers who possibly
have water leaks During each billing cycle, customer's current meter readings are compared to
the previous month's meter read, the current month's one year ago read, and the previous
month's one year ago read Current customer meter readings that reveal a 200% increase or 50%
decrease from the previous month and previous month in the previous year are placed on a
high/low report that is referred to the water meter shop on a daily basis The meter shop checks
out these readings and when applicable turns them over to the Utility Public Communications
staff for audit checks Audit checks help customers identify areas where water consumption is
unusually high as well as identify areas where water conservation practices can be helpful
2.13 Water Conserving Landscaping:
Public education includes suggestions on landscaping and irrigation procedures, which will result
in reduced water consumption and water bills The latest imgation and xenscaping procedures
on public grounds will set an example for the public
Drought/Conservation Plan
IVININQ
Some methods under consideration include
• Establishing platting regulations for new subdivisions that require developers,
contractors, or homeowners to use only adapted, low water using plants and grasses
for landscaping purposes
• Initiating a Xenscape or Texscape program that demonstrates the use of adapted, low
water using plants and grasses Accomplishing this in city parks where citizens can
see what is taking place will demonstrate the City's commitment
• Encouraging landscape architects to use low maintenance plants, grasses, and
efficient imgation systems in prepanng all site and facility plans
• Encouraging licensed irrigation contractors to use dnp irrigation systems when
possible and to design all imgation systems with water conservation features, such as
sprinkler layouts that accommodate prevailing wind direction
• Encouraging commercial businesses to use dnp imgation and use only design
ornamental fountains that recycle water
• Encouraging nurseries and local businesses to offer adapted, low water using plants
and grasses and efficient landscape watenng devices, such as dnp irrigation systems
2 14 Recycling and Reuse.
The City currently operates a wastewater reuse program for supplying treated wastewater
effluent for cooling tower use at the City's Electric Generation Plant on Spencer Road The
Public Utilities Board and City Council received a staff report explonng the feasibility of
expanding this reuse program to serve other customers The expansion of this system would
extend the existing capacity of the water supply, treatment, and transmission systems and lower
operating costs for high volume users Staff recommends the continued expansion of this reuse
program as a strategy to meet future water demands
215 Implementation:
The Assistant City Manager/Utilities or his duly appointed representative will act as the
Administrator of the Water Conservation Plan The Administrator will oversee the execution
and implementation of all elements of the plan He will also oversee record keeping for program
venfication As a means to implement the Water Conservation Plan, the City has recently
implemented the following documents
• An Ordinance by the City to implement the legal documents necessary to enact this
Water Conservation and Drought Contingency Plan
• Enforcement of current Plumbing Code requirements to Use Water Conservation fixtures
and devices
2 16 Goals and Objectives
The City of Denton continues to maintain its goals for water conservation and renew other goals
as follows
• Continue water use reductions to achieve the "average conservation water use" level of
183 gcpd by 2050
• Maintain and enhance the quality of raw water resources
Drought/Conservation Plan
12/20/99
• Use internal programs to minimize water use
• Reduce peak demand
• Continue and expand public education
These aggressive goals for water conservation demand that the City continue its ongoing
programs and coordinate with area cities to develop broad reaching education and public
involvement programs

SINGLE FAMILY WATER AUDIT PROGRAM
PROCEDURES
NOVEMBER 1999
Drought/CQnservauon Plan 12/20/99
INTRODUCTION,
This manual outlines the background and general procedures of the Residential Water Audit
Program Denton Water Utilities water auditors and other department personnel use this manual
so there is a general understanding of the program
BACKGROUND:
The Single -Family Residential Water Audit Program introduces an education tool that will
educate the public about water conservation The intent is to actively demonstrate how
customers can conserve water to lessen the impact of high water and sewer bills This will
involve auditing as well as retrofitting domestic plumbing fixtures with water efficient hardware
In addition, measurement of water used on landscaped areas will help reveal annual water
requirements needed for irrigated areas Expansion to all customers with high water use patterns,
within the City, will occur as the program grows
PURPOSE:
The Residential Water Audit Program evaluates existing water use and actively demonstrates
water savings techniques in single-family homes Audits begin with an analysis of current
versus previous water bills Interior plumbing fixtures are also measured for efficiency so the
customer can make a determination about retrofitting those fixtures with water efficient
hardware, which includes showerheads, faucet aerators and toilet dams A comprehensive
outdoor water use analysis demonstrates existing and required outdoor water use on the
landscape Customers with automatic sprinkler systems can also take advantage of the irrigation
audit, whereby an evaluation of sprinkler precipitation rates determine required watering
frequency and times for the clock -controller
Drought/Censervation Plan

DENTON WATER UTILITIES
WATER CONSERVATION AUDIT PROGRAM
For more information on water conservation call 349-7149
Three different ways to conduct water audits include
❑ Standard Audit
❑ Irrigation Audit
❑ Both
The "standard" audit is a comprehensive indoor audit
along with a brief audit and analysis of the landscape and
outdoor water use The "irrigation" audit is an in depth
analysis of the entire irrigation system
APPOINTMENTS
Establish appointments by telephone and log into a daily
calendar
The following information is written on the water audit
form so the water auditor has the following pertinent
information about the customer
❑ Name of Customer
❑ Customer's street address
❑ Customer's telephone number
❑ Appointment Day (Day of week)
❑ Date of Audit
❑ Time of Audit
❑ Name of Auditor
❑ Account Number
o Date of Tap
Note whether the audit is a standard and/or irrigation
water audit Consumption history provides an outdoor
water use analysis for the customer
Upon arrival at the customer's home the water auditor should ask
the customer to turn off all water using fixtures in the home in order
to check the meter disk or dial for any movement If the meter
moves, a potential leak may exist This will serve as an indicator to
look for leaks inside and outside the home "Yes or "No" on the
form, indicates detection of a leak
Drought/Conservation Plan
12/20/99
often identify leaks on the lavatory, bathtub faucets and showerheads
The major problem associated with leaks on these
fixtures are worn washers and valve seats Refer to
The Retrofit brochure as a guideline for replacing
these parts
00433 Water Use Profile The idea is to give the customer an idea of
lush vol bathroom water use Record all flow rates to the nearest 0 1 gallons

❑ Toilets
❑ Showerheads
low rate ❑ Lavatory Faucets
New flow rate
rate
be noted with a "Y' or "N" on this part of the form
"Y" meaning, Yes a leak exists or "N", meaning No
leak exists The following fixtures should be examined
for leaks
❑ Toilets
❑ Sink Faucets
❑ Bathtub Faucets
❑ Showerheads
Toilets Statistically, the toilet leaks more than any
other plumbing fixture in the home In order to detect
a leak, place a dye tablet in the toilet tank and allow it
to sit about 10 minutes If water in the bowl turns the
color, a leak exists and further investigation is required
to identify the leak Probable causes of leaks could be
❑ Water running into the over -flow tube
❑ Water seeping through the flapper valve
Troubleshooting
If water is runtung into the over -flow tube, you
Can suggest somehow lowering the float,
Thereby lowering the water level below the
Over -flow tube If water is not running into the
Over -flow tube, the next alternative is to replace
the flapper, especially if the customer hears the
toilet filling intermittently This is a simple
and easy replacement and can be done for only
a few dollars
Toilet Toilet flow rates are expressed in terms of gallons per
flush (gpf) Use the following procedure to determine the toilet s
flow
1 Using a tape measure or some other similar measuring device,
measure the width, length, and depth of water in the toilet tank to the
nearest 0 1-inch
2 Use the formula below to determine gpf Round
off to the nearest 0 1 gpf and record on the form
ength x Width x Depth to water line x 0 00433=gp
3 If the toilet is more than 3 5 gpf, insert a toilet dam and ensure it
is properly seated against the floor and walls of the tank
4 Flush the toilet to ensure the maintenance of the water level
behind the toilet dam If not go back to step 3
5 Record the new and smaller flush volume to the nearest 0 1 gpf
(NOTE Depending on the toilet tank, toilet dams save between 0 5
—10gpf )
Showerhead and Sink Faucet Use a 5-second measuring bag to
determine gallons per minute (gpm) for showerheads and faucets as
shown in the procedure below
1 Place the bag so the bag catches the entire stream of water
before turning on the fixture
2 Turn on the water "full blast"
3 Measure for exactly 5 seconds
4 Record to the nearest 0 1 gpm
5 For showerheads If the flow rate exceeds 2 5 gpm, install a new
showerhead
6 For Faucets If the flow rate exceeds 2 0 gpm, install a new
faucet aerator
7 Repeat steps 1 — 4 and record new flow rate All should be
below

Indoor Recommendations
Normally there is one kitchen per household Kitchens In many homes the laundry area will have a washing
most commonly contain the following plumbing Machine and slop -sink Check to make sure there are no leaks on
fixtures the faucet In some cases, install a low -flow aerator If a washing
❑ Faucet machine is present, note whether it has water saving cycles If so,
❑ Dishwasher remind the customer to make use of them in the event full loads
❑ Garbage Disposal cannot to washed
Leak Detection Supple observations will detect leaks
in the kitchen faucet The major problem associated
with leaks is worn washers and valve seats Refer the
customer to the Retrofit brochure as a guideline for
replacing these parts
Faucet Flow Rates
Use the procedure on page 4, for showerheads and
faucets, to measure the flow rate and determine the
need for a new low -flow aerator If the flow rate
exceeds 2 0 gpm and/or the faucet aerator is in bad
condition replace with a new aerator then measure and
record the new flow rate
Dishwasher
Note whether a dishwasher exists and if it has water
saving cycles Encourage the customer to use the
shorter cycles and wash full loads only
Garbage Disposal.
Note if there is a garbage disposal Advise the
customer to use the garbage disposal only when
necessary to eliminate the use of excess water
Other items to look for are bubbling laundry hoses, particularly on
the hot water side If the hose is swelling, encourage the homeowner
to replace to prevent bursting so they can avoid paying for
unnecessary property damages and high water consumption
INDOOR RECOMMENDATIONS
Base suggested actions on leaking fixtures and other identified uses
that could potentially reduce water use inside the home

This portion of the water audit is for customers with
automatic sprinkler systems that are clock -controlled The
goal of the irrigation audit is to determine appropriate
watering times and frequencies on a zone by zone basis
The irrigation audit includes four (4) components
1 Walk-through
2 Precipitation Tests
3 Calculations
4 Recommendation Watering Schedule
WALK — THROUGH
1 Have the owner activate each sprinkler zone for a few
minutes to get an idea of the type of sprinkler heads &
existing inefficiencies System inefficiencies mclude
such examples as
❑ Heads not popping up high enough
❑ Bushes or other obstacles in the way of the
spray
❑ Bad Coverage
❑ Brown spots on the lawn
❑ Low pressure
❑ Inappropriate sprinkler heads
as shown on the form above on a zone
by zone basis
❑ Number of sprinkler heads
❑ Type of sprinkler heads The most common are pop-up rotor and
gear drive
❑ Existing clock settings which includes minutes per zone and every
how many days
This is the most critical part of the water audit since there is immediate
customer involvement and inefficiencies
PRECIPITATION TESTS
The precipitation tests give ment to the irrigation audit and essentially
justify recommended watering Prepare precipitation tests on at least
two (2) zones Potential test zones include
❑ One impact and one pop-up zone
❑ One zone in front and one in back
❑ One zone with brown spots (bad coverage) and one with
good coverage
For the most part, it will be a judgement call and dependent on
customer preference

Zone
COMMENTS:
3 Once the catch cans are set up, turn on the zone for
exactly 5 minutes Relax and wait for it to end
4 Turn off the zone once 5-rnurutes has expired
Measure and log the volume to the nearest 5 milliliters for
each catch can
5 Repeat steps 1-4 for the next zone
CALCULATIONS
Refer to worksheet on left in Appendix B to calculate the
recommended watering times for each zone
1 Add up the total volume and divide by the number of
catch cans to get an average precipitation rate in
triilliliters
2 Divide the factor, 341, by the average volume to
figure recommended minutes
3 Repeat steps 1 & 2 for the next test zone
Calculated minutes are based on l per week of
supplemental watering and two short -repeat cycles every

The Residential Water Audit Program is unique because it is the most elaborate service Denton Water Utilities will
perform for a customer in a single family home This program is effective because gams are made in water savings
and customer confidence
MEETING THE CUSTOMER
The auditors should always conduct themselves m a professional manner throughout the water audit The following
checklist offers some helpful hints
• Identify yourself as a water auditor from the Denton Water Utilities
• Encourage the customer to follow along during the water audit If the customer is preoccupied with other
matters, always inform them of your whereabouts throughout the water audit This gives the customer a sense
of confidence in the program
• Remain focused on the water audit While it can be tempting to browse and look at the customer's belongings,
especially in an elegant home, it may give the impression of "casing the)omt "
NO SHOWS
No shows make up no more than 10% of scheduled audits If the customer does not show up for a scheduled
appointment within 10 minutes go on to the next appointment or daily business Contact the customer later for a
new appointment

CHAPTER 3
DROUGHT CONTINGENCY PLAN
30 Declaration of Policy, Purpose, and Intent.
Drought and a number of other uncontrollable circumstances can disrupt the normal availability
of the City's water supply Even through the City may have an adequate water supply, the
supply could become contaminated, or a disaster could destroy the utility infrastructure needed to
transport, treat and distribute water to customers Although water emergencies may not be the
result of a drought condition, for the purposes of this plan they are referred to as a drought
contingency or water emergency condition
This Drought Contingency Plan describes the conditions that require short-term water demand
management in the City of Denton and establishes policies and procedures that offer strategies
for a timely and effective water management response Such a response is needed when water
use in any area approaches the system's supply, treatment, or delivery capacity Examples
include drought conditions, unusually high water demands, unforeseen equipment/system failure,
or contamination of a water supply source
In order to conserve the available water supply and protect the integnty of water supply facilities,
with regard for domestic water use, sanitation, and fire protection, and protect and preserve
public health, welfare, safety and minimize the adverse impacts of water supply shortage or other
water supply emergency conditions, the City of Denton hereby adopts the following regulations
and restrictions on delivery and consumption of water
Water uses regulated or prohibited under this Drought Contingency Plan are considered non-
essential and continuation of such uses during times of water shortage or other emergency water
supply conditions constitute a waste of water, which subjects the offender(s) to penalties as
defined in this Plan
31 Public Involvement:
The purpose of this Plan is to establish a policy in case of shortages or delivery limitations in the
City's water supply, or in the case of equipment malfunctions or similar emergencies The
Drought Contingency Plan is adopted and incorporated as if frilly set forth and enforceable as a
part of this Plan As recommended by the Texas Water Development Board (TWDB) and the
Texas Natural Resource Conservation Commission (TNRCC) the plan consists of escalating
phases of water use restrictions based on appropriate triggering conditions developed by Denton
Municipal Utilities The plan provides procedures for voluntary and mandatory actions placed
into effect to temporarily reduce the demand placed upon the City's water supply system during
a water shortage A copy of the plan hereby adopted shall be on file in the office of the City
Secretary
Drought/Conservation Plan
12/20/99
32 Public Education
Successful implementation of the Drought Contingency Plan depends on effective
communication with the public Denton Water Utilities (DWU) must exchange ideas with the
public to understand its needs and determine what water uses are most essential The public
must believe that the measures adopted are credible A public awareness and education
campaign will be successful if it conveys that
• The water management condition is real
• Reductions in water demand are necessary
• The adopted measures realistically correspond to the seventy of the situation
• All Customers share the inconvenience during water shortages
• The City of Denton is effectively managing the existing water supply
To accomplish these six objectives, the City will take the following steps dunng drought or water
emergency conditions
• Alert the public and keep the public regularly informed through local media (Media
contacts are listed in Appendix A)
• Initiate public discussions when appropriate
• Promote public understanding of the Drought Contingency Plan and convey restrictions
required should situations worsen
• Educate the public about ways to use water more efficiently
• Gather public support for the plan's actions
• Highlight the leadership role of the city government to save water
The campaign will work to gather support from various forms of news media to successfully
keep the public informed Once initiated, and especially during stages 3 and 4, the City and the
news media will provide regular alerts to successfully implement public awareness and education
through the following options
News Media:
• Radio and television public service announcements
• Newspaper and magazine announcements

3.6 Plan Applicability:
This Plan applies to all users, premises, retail and wholesale customers receiving water from the
City of Denton's water system This plan also insures that the City of Denton water utilities will
maintain an adequate water supply for essential public needs
3.7 Triggering Criteria for Initiation and Termination of Drought Response Stages.
Monitor all relevant components of the City of Denton water system to ensure that actions taken
are based on current and reliable information Denton Water Utilities (DWU) will monitor the
system, at a minimum, on a weekly basis until such point when projections based on past use
indicate a tngger could be reached within two weeks At this time, daily monitoring and
reporting to the Assistant Director of Water Utilities will occur
Initiation: The ACM/Utilities advises the City Manager when conditions exist to initiate a
Plan stage The City Manager may then order the initiation of the appropnate stage of the Plan
To be effective, public notification must come before actual initiation
Meeting or exceeding one or more trigger conditions is sufficient cause to initiate a Drought
Contingency Plan stage Factors influencing this decision include, but are not be limited to, the
time of year, weather conditions, anticipation of replenished water supplies, or anticipation that
facilities will come on-line to serve capacity
Drought/Conservation Plan 12/20/99
Duration, Changes, and Extensions- The order can be made effective for up to, but not more
than, 60 days from the date of communicating a given stage of the plan that requires curtailment
of water use by the public (i a stages 2, 3 or 4) Upon recommendation of the ACM/Utilities, the
City Manager may upgrade or downgrade a stage when the conditions triggering that stage
occur To be effective, initiate the order by public notification Upon recommendation of the
ACM/Utilities and City Manager, the City Council may extend the duration of an order for
additional time periods, not to exceed 120 days each
Termination The ACM/Utilities will advise the City Manager when conditions exist to
terminate a stage of the Plan The City Manager may then order the termination of the
appropriate stage of the Plan
Termination of any stage will occur if the corresponding drought contingency condition has
subsided or been eliminated and if the corresponding trigger condition is no longer needed and
would be unlikely to recur upon termination
Public Notification: The following procedures are required to initiate or cancel each stage of
the Drought Contingency Plan
• Notification by public announcement via electronic media
• Notification published in newspapers of general circulation to the city within 24 hours
after the public announcement
• The order becomes effective immediately upon publication
Wholesale Customer Notification- The City of Denton will provide notice, by telephone and
by certified mail, to all affected wholesale customers when any stage of the Drought
Contingency Plan has been initiated or terminated If the City implements pro rata water
allocations, notice will be made by telephone and certified marl to all wholesale customers
informing them of their monthly water usage allocations
TNRCC Notification. The City of Denton will notify the executive director of the Texas
Natural Resource Conservation Commission (TNRCC) within five business days of the
implementation of any mandatory provisions of the Drought Contingency Plan (stages 2, 3, or 4)
Such mandatory provisions include implementation of pro rats water allocations to wholesale
customers
3.8 Four Stages of the Drought Contingency Plan: Proactive management is the best
way to lessen the potential impact of a drought contingency situation on the citizens of Denton
and its wholesale customers The City of Denton has established four successive stages to
implement progressively stringent management measures Meeting or exceeding the water -
reduction goals in the early stages reduces or eliminates the need to progress to later stages The
entire public benefits if the City takes responsible action in the early stages of a drought
contingency situation The City uses three distinct types of water shortage situations to establish
the trigger conditions listed below
Drought/Conservation Plan
12/20/99
Trigger conditions: The trigger conditions for each of the three types of water management
conditions and each of the four water management plan stages are provided in the Table 3 1
Table 3 1 shows the rationale for each trigger condition
• For a Type A situation, preservation of the total water supply will be critical and
corresponding water management measures should stress overall reductions in water use
An extended drought causes this condition The best opportunity to respond to a drought
is early in the drought cycle Drought Contingency measures should stress overall
reductions in water demand (i e , average -day water demand)
• For a Type B situation, in which the water demand approaches the delivery capacity of
the system, the peak water demand will be critical, and corresponding drought
contingency measures should stress water -use reductions or shifts to off-peak hours In
this situation, the ultimate goal of Stages 1, 2, and 3 will be to avoid triggering the next
stage A Stage 4 trigger requires immediate and severe water demand reductions
Equipment or system failures that result from increased stresses to the transmission,
treatment, or distribution systems can worsen a Type B situation
An increase in water demand causes this condition In the short term, this typically occurs
during the summer months when irrigation requires more water In the long term, it
could occur if treatment plant or distribution system expansions do not keep pace with the
growth in consumer demand Drought contingency measures should stress reductions in
peak water demand or redistribution of the demand to off-peak hours
• For a Type C situation where deficiencies limit the supply capacity, both water -use
reductions and shifts to off-peak hours may be necessary Although the area involved
may be localized, immediate action requiring water demand reduction is necessary
Depending upon the seventy of the triggering conditions, it is feasible that the plan could
proceed immediately to implementation of stage 3 or stage 4 A break in a large
transmission main, mechanical failure to one or more large pumps, or production plant
breakdown causes this condition Contamination of water supplies or other unforeseen
occurrences may also instigate this condition They may anse with little warning and
require immediate and/or aggressive actions Drought contingency measures should
stress reductions in peak water demand or redistribution of the demand to off-peak hours

Table 3 1 Summary of City of Denton Water Utilities Trigger Conditions
3.9 Rationale for Trigger Conditions:
• Type A, Water supplies are low Since Denton obtains water from two supply
reservoirs shared with the City of Dallas and Dallas Water Utilities has the ability to
balance water supplies between reservoirs, tngger conditions for low water supplies are
based on the water supply available in the combined lake system shared by both cities
Modeling of the reservoir system shows how supplies diminish during a drought equal to
the drought of record This information was used to select the tngger levels for
implementing measures that correspond to years two, three, four, and five of an extended
drought It is anticipated that the City of Denton will initiate Type A Water Management
Plan stages consistent with the actions by the City of Dallas for this shared multiple
reservoir system
Type B, Water demand approaches system capacity Base tngger conditions on the
available delivery capacity relative to water demand In most cases, the limiting
constraint will be the treated water distnbution system To set the tngger conditions, the
City examined water demand and the system's delivery capacity The selected tngger
levels provide sufficient time delay between each stage and time to implement measures
that correspond with the seventy of the capacity shortfall
Drought/Conservation Plan
12/20/99
• Type C, Short-term deficiencies limit supply capability The trigger conditions
for short-term deficiencies limiting water supply capability are based upon how much
water supply or delivery capacity remains available relative to water demand for all or
part of the system Tngger conditions, which will be determined when the deficiency
occurs, will be based on the area impacted, existing conditions, and options available
within the Denton Water Utility System at that time
3 10 Water Management Measures:
Section 3 7 outlined the drought contingency stages and the monitonng for initiation and
termination This section outlines the responses at each stage Because the most effective
response to a given drought management condition may vary on the type and factors unique to
the situation, the City of Denton Water Utilities has prepared menus of possible actions The
ACM/Utilities determines appropriate actions before initiation or at any time during a drought
contingency stage
Each stage is listed below, followed by a brief description of the situation and the type of actions
that may be required
