CITY OF KENT
WATER CONSERVATION PlAN
1993
This document details the Water Conservation Plan for the City of Kent in keeping
with the elements of the South King County Coordinated Water System Plan (SKC
CWSP) and King County Ordinance #9461. The conservation plan is designed to
improve the efficient delivery of water, reduce the amount of water wasted in the
delivery process, and increase the available water supply. The City of Kent, in
addition to other Puget Sound region communities, realize that water is a life-essential,
limited resource that needs protection, preservation and conservation.
The City of Kent has been an active participant in the South King County Regional
Water Association (SKC RWA) having implemented various water conservation
programs identified in their Guidelines for Water Conservation Programs adopted May
21, 1991.
WATER USE DATA COLLECTION REQUIREMENTS
As identified in the Interim Guidelines prepared by the Department of Ecology,
Department of Health, and Washington Water Utilities Council, minimum data
collection is required to project public water system demands and to provide a basis
for the evaluation of the effectiveness of conservation programs. The year 1991 has
been selected as the baseline year for identifying per capita consumption. Data
collection for a six year period between 1991 and 1996 is desired to determine and
evaluate consumption trends and the effectiveness of conservation programs. The
data collection schedule for Kent is shown below by data type and frequency.
*source of supply meter -daily reading
*service meter usage recorded
single family -every two months
multi-family -every two months
commercial/public/industrial-every month
irrigation/community system -semi-annual
*unaccounted for water
*annual total by source
*peak day/peak month
*population served
-*conservation data
~''Au··~
WATER DEMAND FORECAST
The Interim Guidelines identify appropriate demand forecasting methodology for public
water systems to evaluate supply demands. Kent's water demand has been forecast
through the Water System Plan for the City of Kent and includes total water demand
forecasting as well as separate projections for residential and commercial/industrial
consumption. The projections are in line with those projected under the SKC CWSP.
Factors used in developing future demand forecasts will include water use, land
use/zoning/capacity, water rates, and conservation savings as recommended in the
Interim Guidelines.
WATER CONSERVATION PROGRAM ElEMENTS
Kent's water conservation program elements are detailed below. Program elements
previously implemented as indicated in the SKC RWA Recommended Water
Conservation Program (attachment A), include program promotion, single family/multi-
family conservation kits, water leak detection, meters for all customers, and seasonal
pricing.
In addition, the City has implemented several water conservation programs with the
SKC RWA. Kent will continue to work with the SKC RWA to develop and implement
programs at the regional level as well as the local level.
Kent recognizes the need for long range conservation planning to meet future water
demands. In December, 1992, the City hired a Conservation Specialist to coordinate
the water conservation program. In addition, as shown in the Water System Plan for
the City of Kent, other than obtaining a portion of the supply from Tacoma's Green
River Pipe Line #5, future source development involves constructing an Impoundment
Reservoir. Said impoundment reservoir would store excess winter flows from existing
sources (Clark Springs, Kent Springs and Pipe Line #5) for utilization during the peak
summer demand period. This will result in conserving the regions ground water
resources which would normally be tapped to meet the peak summer demands.
Details of Kent's Water Conservation Program, including program objectives,
elements, level of participation, schedule for implementation and budget are detailed
in this report.
PROGRAM OBJECTIVES
To meet the City's goals of attaining a 6.5% water reduction by 1995 and 8%
reduction by the year 2000, the conservation program will achieve the following
objectives:
*improve efficient delivery of water
*reduce the amount of water wasted in the delivery process
*increase the available water supply
*coordinate and support services and programs with adjacent water purveyors
*reduce peak daily consumption
*reduce peak monthly consumption
*reduce total annual consumption
*develop public awareness and education
ASSESSMENT OF CONSERVATION ACTIVITIES
The recommended conservation programs outlined in the Interim Guidelines are
grouped into four categories: ( 1) public education, (2) technical assistance, (3)
system measures, and (4) incentives/requirements. The Interim Guidelines require
Kent to implement a moderate program as identified in attachment A. Kent's water
conservation plan includes conservation elements above and beyond the minimum
elements identified in the Interim Guidelines.
PUBLIC EDUCATION
The public education programs which the City is implementing are discussed below.
These meet the requirements of the Interim Guidelines and include school outreach,
speakers bureau, program promotion, and theme shows and fairs.
School Outreach Programs -Since 1991, the City of Kent has been involved in
securing and scheduling the "Small Change Theatre" to perform plays at local
elementary schools to teach children about the importance of water conservation.
Additional programs and activities will be developed to include school presentations,
tours of facilities, special projects involving students of all ages, and assisting with
preparation of curriculum material.
With the development of a conservation ·material library, schools will have access to
educational materials to assist with water conservation programs in their classrooms.
Speakers Bureau -The City of Kent will work cooperatively with the South King
County RWA to develop a speakers bureau. City staff will be available to give
presentations to groups, organizations, schools, businesses, and local residents, to
encourage water conservation practices. Kent will prepare slide and video
presentations with copies of video presentations on water conservation available for
review at local libraries.
-3-
Program Promotion -In 1991 and 1992, Kent worked cooperatively with the SKC
RWA to distribute lawn watering calendars to area residents and will incorporate the
lawn watering schedule into a summer watering campaign. Kent also distributes
water conservation information through it's utility bills and through articles in the local
newspaper. Brochures produced by the Seattle Water Department, Department of
Ecology, Department of Health, and other regional water agencies are also available
at local libraries, City facilities and departments.
The City will be producing an "Environmental Awareness" brochure/newsletter for
distribution which will include water conservation tips and information.
Special "How To" classes and workshops will be offered to citizens to show methods
of installing home water conservation devices, to provide information on types of
devices available, water conservation ideas and methods for the home and business,
outdoor watering techniques, water conserving landscape ideas and alternatives, how
to read a water meter, and water supply sources and issues.
A "Home Water Conservation Survey" was conducted in September 1991 in
cooperation with the SKC RWA, the cities of Bellevue, Everett, Fife, Kent, Puyallup
and Tacom@. Results of the survey will be incorporated into public education
programs.
The development of a conservation library will include a wide range of multi-media
materials. Brochures, pamphlets, books, portable displays, slide and video
presentations relating to water conservation will be available to use at fairs, town
meetings, community events, public meetings, schools and businesses.
Theme Shows and Fairs -The City of Kent provides staff, water conservation
materials and displays to local and regional theme shows, fairs and the annual City of
Kent Town Meeting. Exhibits are available to use at events throughout the area.
TECHNICAL ASSISTANCE
Kent currently offers assistance to customers within it's service area, in addition to
working with the SKC RWA and other purveyors to provide technical assistance to
customers as well as researching and conducting technical studies.
Purveyor Assistance-The City of Kent will continue to work with other purveyors to
provide assistance in developing and implementing conservation plans. The City's
participation in the Water Conservation Coalition of Puget Sound and regional
coordination in developing and implementing programs for the Puget Sound area, can
greatly increase the effectiveness of water conservation.
-4-
Customer Assistance -Through the development of educational programs and
information, and the training of staff on water conservation methods and devices, the
City will provide direct assistance to customers to facilitate water conservation.
Technical Studies -In 1991, the City of Kent, South King County RWA and other
purveyors, hired Market Data Research to conduct a residential indoor water use
survey. Survey results included customer's perceptions of available water supplies,
customer behavior and attitudes, and current knowledge and use of conservation
practices. Customers were also asked to respond to different conservation options
available to assure future water supplies. Information collected from the survey will
be used to develop appropriate conservation programs. The survey will be conducted
in future years to audit changes in customers conservation practices, awareness and
attitudes. Future plans will also include water audits of commercial and industrial
customers.
The City will continue to work with the SKC RWA and other water purveyors to
collect data and research new technology to develop new programs which will
produce measurable water savings.
Bill Showing Consumption History-Kent will be implementing new programming on
their customer water bill showing a graph depicting water consumption history, thus
encouraging water conservation.
SYSTEM MEASURES
System measures include a 100 percent metered system, unaccounted water/leak
detection, and high technology meters.
Metered Systems-The City of Kent requires metered systems for all domestic and /or
industrial consumption of water. Additionally, all water service connections and
plumbing must conform to relevant Washington State plumbing codes and City of
Kent standards.
Unaccounted Water/Leak Detection-In 1991, the City conducted a leak survey of the
oldest sections of town. A very minimum number of leaks were found and repaired.
The City's inspection, repair, and replacement program is ongoing as a part of the
preventive maintenance program.
High Technology Meters-In recent years, the City's water system was upgraded to
include a state-of-the-art automated computerized control and telemetry system.
-5-
INCENTIVES/REQUIREMENTS
Incentives and requirements for the water conservation plan include single
family/multi-family retrofit kits, new conservation practices for nurseries and
agriculture, landscape management, conservation pricing, utility financed retrofit,
mandatory seasonal water restrictions, potential recycle/reuse, and pressure reduction.
Single Family/Multi-Family Retrofit-The City distributes kits containing water saving
devices at it's annual town meeting in addition to educational and informational
materials. The City of Kent Home Repair Program is also available to low-income and
elderly residents to assist in installing devices and making minor repairs. Kent will
work with the SKC RWA, Tacoma Water Division, Seattle Water Department, City of
Everett, the BPA, and other utilities, to distribute devices in a regional effort. Kent
·will also look at programs and methods to deliver water conservation kits and
information to single family and multi-family customers.
Nurseries/Agriculture -The City will continue to encourage the application of new
technology for irrigation systems that will achieve greater irrigation efficiency. A
computerized irrigation system was installed during construction of the City's new
golf course in 1991, to increase efficiency in irrigation. Water for the irrigation
system is taken from on-site wells. City facilities and departments will continue
working together to promote and publicly demonstrate water conservation practices.
Landscape Management/Playfields -Kent will continue to encourage the use of low
water demand landscaping by commercial, industrial, public and private water
customers throughout the area. Public education materials, workshops,
demonstrations and use of the speakers bureau, will be utilized to promote new
landscaping ideas and methods to achieve greater irrigation efficiency.
City Departments will work together to inventory properties, facilities, and develop
plans for repairs and upgrades to irrigation systems. Results of Tacoma's landscape
pilot study will be reviewed to help develop outdoor irrigation conservation measures
and future landscape standards.
Conservation Pricing-In July, 1992, The City of Kent implemented seasonal water
rates to encourage water conservation. Implementation of the water bill showing
consumption history and providing customers with education and information relating
to water conservation will encourage wise and efficient use of water.
Utility Financed Retrofit -The City and SKC RWA will review program options for
utility financed retrofit. Potential programs range from rebates to providing fixtures
at the system's cost or at no cost. Kent's local retrofit program as discussed earlier
is financed through the City's water fund.
-6-
Mandatory Seasonal Restrictions -The City has adopted "Water Shortage Emergency
Regulations" establishing methods and regulations for rationing water during a water
shortage emergency. Future plans also include preparing a waste water ordinance
focusing on wasteful uses of water such as gutter flooding, watering sidewalks and
driveways, etc., and an outdoor watering policy such as watering schedules to reduce
peak day impact on the system.
Recycling/Reuse -The City of Kent is attending meetings with METRO on possible
water reuse. METRO is considering a regional study to look at potential
recycling/reuse opportunities. Kent will continue to examine possibilities for water
reuse and recycling as a method to reducing water demands. An example would be
to encourage reuse of water through water rates which provide an incentive for major
industrial water users to develop treatment/reuse/recycle systems.
Pressure Reduction -Pressure reduction is used throughout the City. Due to terrain,
Kent's water system is comprised of five distinct pressure zones. Additionally, several
of these zones are further subdivided into two or three subzones. While this provides
a working pressure of 35-85 PSI throughout the system, it also makes the system
very complicated and difficult to maintain. Any further breakdown of the service area
will require weighing the operational integrity and reliability of the system against any
conservation gain.
MONITORING REQUIREMENTS
Monitoring and evaluating the individual conservation measures during and after
implementation of the conservation plan are essential to judging the effectiveness of
the plan. It is important to develop reliable data to use in analyzing the actual water
use after the conservation plan has been in place for a period of time, to identify
whether goals and objectives are being met. This process can identify areas of the
program that need to be changed. Periodic review and evaluation to "fine tune" the
plan is important. Factors such as population, growth rate, and revenue will be taken
into account when an evaluation is conducted. Looking at change in population and
growth rate will help determine what effect the changes have on the demand for
water.
Important monitoring data to keep for each conservation measure includes:
1. The number of customers affected by the measure in each category, i.e. the
number of customers who received a bill insert, brochures, read newspaper
articles, etc.
2. The amount of conservation literature and /or devices distributed for each
measure.
-7-
3. The expected amount of savings from each of the distributed conservation
devices.
4. The number of customers who actually received conservation devices or
responded to offers of assistance.
5. The number of customers who actually installed the conservation devices.
6. The average water used in a specific activity by each category of customer
before implementation of a conservation measure targeted for that activity
and after implementation of the conservation measure.
7. Data on how changes in weather affect the demand for water in particular
activities targeted for conservation measures.
SUMMARY
Implementation of the water conservation plan will have numerous benefits on our
environment. Saving water today will improve wildlife and fisheries habitat, increase
the aesthetic and recreation value of streams and rivers, and protect water sources
for meeting future demands.
