PUBLIC MEETING f This being the date set and proper notices having been posted and published in
Utility: 2013-2018 Water Use accordance with local and State laws, Mayor Pro Tern Corman opened the
Efficiency Goal Setting public meeting to consider adoption of the 2013-2018 Water Use Efficiency
(WUE)Goal.
ft' r / 1" Utility Engineering Supervisor Abdoul Gafour reported that the Municipal
Water Law became effective in Washington State on January 22,2007. He
stated that the purpose of the law is to improve the efficient use of water and
to strengthen the ability to meet the competing needs of a growing population,
agriculture, industry, and fish. Mr. Gafour explained that one requirement of
the law is to set water use efficiency goals and update them every six years.
,
October 14, 2013 ',so- Renton City Council Minutes "'" Page 306
t Mr. Gafour reported that the following goals were adopted in 2007:
i
• Reduce water system leakage to 10%or less by the year 2010;
• Limit peak day demand to 16.5 million gallons per day(MGD); and
• Continue reduction of average annual water consumption by.5% per
year per connection.
Mr. Gafour reported that the City has met all three goals. He stated that City
non-revenue water leakage has dropped from 19%in 2007 to 8.5%in 2012. He
explained that this means in 2007 there were 204,000 gallons of water lost per
day compared to 75,000 gallons in 2012. Mr. Gafour remarked that this
significant reduction is due to the City's maintenance program on leak
detection, repair of water mains, and the implementation of the automated
meter reading program that allows for early notification of customer leaks. He
also reported that the City's peak day water demand has dropped from 15
million gallons per day in 2008 to 12 million gallons per day in 2013. Lastly, Mr.
Gafour reported that the City's domestic consumption account dropped from
128 hundred cubic feet to 116 hundred cubic feet per year,which is
approximately a two percent annual decrease. He pointed out that this is
significantly better than the .5% per year reduction goal adopted six years ago.
Continuing, Mr.Gafour reported that in January 2012 the City entered into a
50-year contract with Seattle Public Utilities for long-term water supply to
supplement the City's own supply if needed. He explained that because of this
new contract the City is now a member of the conservation group known as the
Saving Water Partnership,which consists of Seattle Public Utilities and 18 other
wholesale water purveyors from neighboring cities and districts. Mr. Gafour
further explained that the group collaborated in the development of the new
Water Use Efficiency(WUE)goal for 2013-2018. He added that the group
determined that a new source of water supply for the whole region would not
be needed until the year 2060 despite continued population growth.
Mr. Gafour reported that the new regional common goal is to "Reduce per
capita water use from current levels so that the current average annual retail
water use of all members of the Saving Water Partnership is less than 105
million gallons per day from 2013 through 2018 despite forecasted population
growth." He stated that the Washington State Department of Public Health has
accepted the new goal, and each utility governing body must adopt the goal.
He also stated that each utility must report their water use annually,and the
consumption is reported as one common number to evaluate the goal.
Concluding, Mr. Gafour reported that the Saving Water Partnership is exploring
new options to improve water conservation communications,especially with
non-English speaking communities. He stated that the partnership is also
increasing youth and community education on conservation through expanded
school programs, and will conduct irrigation efficiency programs with local
contractors. Mr. Gafour also noted that residents can research water
conservation resources on the website savingwater.org.
Public comment was invited.
October 14, 2013 wr Renton City Council Minutes " ' Page 307
Renate Beedon (Renton)stated that the paperwork handed out for this public
meeting indicates that the City is saving water through the use of new shower
heads,toilets, washing machines, and other appliances. She remarked that she
recently upgraded her appliances and fixtures,and inquired as to how the City
knows that people are upgrading to more efficient fixtures.
Mr. Gafour responded that the Saving Water Partnership has a list of water
conservation programs and projects completed in Renton over the last few
years. He cited numerous businesses and apartment complexes that have been
retrofitted with newer fixtures and appliances as examples.
Mayor Pro Tern Corman further explained that local building supply and
hardware stores are all now selling the more efficient fixtures and appliances so
anyone remodeling their homes or businesses will be installing these new
plumbing fixtures.
Utility Systems Program Specialist Helen Weagraff explained that plumbing
fixtures and appliances all use a standardized rating system that allows
municipalities and others to measure their water conservation and efficiency.
Ms. Beedon suggested that the City should utilize a system to recognize
neighborhoods that conserve water. She noted that Puget Sound Energy uses
smiling or frowning faces on customer bills to indicate whether or not
I customers are conserving energy.
Councilmember Persson pointed out that Renton residents receive water from
three sources: City of Renton,Water District#90, and Soos Creek Water and
Sewer District. He asked if the two districts were also part of the new water
conservation consortium.
Mr. Gafour affirmed that both Soos Creek Water and Sewer District and Water
District#90 are members of the conservancy. He explained that all members of
the Saving Water Partnership now have the same Water Use Efficiency goal for
2013 through 2018. He further explained that as long as water consumption for
Seattle Public Utilities and the 18 other water purveyors is below 105 million
gallons per day for 2013 through 2018,then the partnership has met this new
goal.
Councilmember Taylor added that there has been a collective improvement for
all of the members of this conservancy because each utility system is
benefitting from the collective upgrades to the regional water system.

AUDIENCE COMMENT Howard McOmber(Renton)stated that October 29, 2013 marks the 100th
Citizen Comment: McComber anniversary of the Mormon Church's involvement with sponsoring the Boy
—Boy Scouts of America Scouts of America. He stated that he believes that Boys Scouts is a wonderful
organization that helps young men to succeed in life. He remarked that the
church he represents provides scouting opportunities for any boy ages eight to
18 in the City of Renton at no charge. He indicated that he would be sending
invitations to City officials to celebrate this event on October 29.

Water Use Efficiency Program
Information Packet for 2013 Goal Setting Meeting
October 14, 2013 at 7:00 p.m.
Renton City Hall, Council Chambers
The Water Use Efficiency Rule
Background
The State of Washington adopted the Municipal Water Supply-Efficiency Requirements Act,
commonly called the Municipal Water Law (MWL) or the Water Use Efficiency Rule in 2007. To
meet the requirements of this new rule, the City of Renton developed Water Use Efficiency
(WUE) goals, which were approved by the City Council on November 19, 2007.
The MWL is intended to help meet the growing needs of communities, agriculture, industry,
and to conserve water for fish. The rule is intended to help:
• Provide more certainty and flexibility for water rights held by water systems.
• Improve the ability to plan for future growth.
• Offer greater flexibility to solve public health problems with water right changes and
transfers.
• Advance water use efficiency.
• Assure greater reliability of safe drinking water for communities.
What are the requirements of this rule?
The rule requires municipal water suppliers, such as Renton to use water efficiently and
demonstrate that they are doing so. Specifically, water systems must:
• Develop goals through a public process and enact WUE measures to manage water use.
• Reduce water system leakage to 10 percent or less.
• Install meters on all customer connections by 2017 to accurately account for water use
and leakage.
• Report annually on their progress in using water efficiently.
How will this affect Renton?
To comply with this rule, we are:
• Conducting a water system audit that will allow us to account for all water used.
• Setting goals for water use efficiency through a public process.
• Re-evaluating our water supply and our forecasts for future water demands.
• Reporting each year on our progress toward these goals as part of the Consumer
Confidence Report we send to all customers.
Renton's Water
Water Supply Characteristics
All of our drinking water comes from groundwater. Based on production of the last five years,
about 85 percent of our drinking water is supplied by five wells located in downtown Renton,
which is pumped from a source known as the Cedar Valley Aquifer. Approximately 14 percent
comes from Springbrook Springs, which is located at the south end of the City. These water
sources are very clean and need minimal treatment.
The City also pumps from three deep wells known as the Maplewood well field located under
the Maplewood golf course. These wells are a backup water source and, as such, are not
utilized continuously. The Maplewood water is also very clean, but because of its natural
mineral content, it must first be treated before it can be co-mingled with the water from the
other sources.
In January 2012, Renton signed a long-term agreement (2012—2062) with Seattle Public
Utilities to purchase water. This water will assure that the City has a secure supply of water,
especially during peak summer usage periods. During the first year of 2012, the City bought 3.1
million gallons of supplemental water from Seattle, which represents 0.01%of the year's water
supply.
Water Use Characteristics
The City's customer and water use characteristics are important considerations for identifying
WUE objectives,goals and measures.
Who uses the water?
The Renton Water Utility provides water for an estimated population of 62,100 in its retail
water service area. The rest of Renton citizens receive water from surrounding water
providers. Renton provides water to approximately 15,505 residential customers and 1,917
non-residential (commercial, industrial,government and schools) customers. In 2012, the City's
customers used an average of 6,483,012 gallons a day.
As shown in Figure 1, single-family residential customers,who made up 79 percent of total
system connections, consumed 35 percent of total retail water sales. The multi-family
residential customer class accounted for 10 percent of system connections and 22 percent of
water use. Commercial users account for six percent of all system connections and use 18
percent of all water consumed. Industrial customers account for less than one percent of
system connections and two percent of water use. While only four percent of the total number
of accounts, irrigation use accounted for 13 percent of total water used. Wholesale water to
Skyway,SPU water to Boeing, and water consumption at the King County Wastewater
Treatment Plant site accounted for roughly eight percent of the City's consumption.

Water System Plan Update
City of Renton
When does the water get used?
Water consumption is closely related to the weather. Year to year variations reflect drought
years, hot years or wet years. The largest variations in water use are seasonal. Typically in
Renton, the highest water use is during the period of June through October. During these five
months,the average monthly water consumption is about 45 percent higher than the other
seven months of the year. The average day consumption in 2012 was 6.48 million gallons. The
peak day use in 2012, which occurred on September 7,was 11.46 million gallons. The increased
summer consumption is due primarily to irrigation. The current automated meter reading
project,that is underway, will allow finer detail about the timing of water consumption.
Water Demand Forecast
The City's future water demand is estimated based on current use and anticipated growth
within the Renton Water System Area (RWSA), utilizing data provided in the Puget Sound
Regional Council's (PSRC's) Population, Households, and Employment Forecast database.
In general,there is very little vacant land within the City's current RWSA;consequently,the
growth capacity within the City's RWSA is limited. The majority of future growth is projected to
occur within the Regional Urban Center and the Sunset Area Community Planned Action
redevelopment boundaries. Projections of the average and maximum daily demands through
2071 are shown in Figure 2.

Current Water Use Efficiency Program
Current (2007—2013)Goals
Our current, adopted November 19, 2007, Water Use Efficiency goals are:
1) Reduce distribution system leakage (DSL)to ten percent or less by 2010.
2) Cap the peak day demand at 16.5 mgd until 2015.
3) Continue reduction of average annual water use by 0.5 percent per year.
Goal Achievements
1) Our first goal addressed distribution system losses. The Municipal Water Law requires that
DSL be 10 percent or less based on a three-year rolling average. If a system's losses exceed this,
then it must develop a Water Loss Control Action Plan (WLCAP). Because our DSL in 2007 was
above 10%, a WLCAP was developed and began in 2008. The following figure shows the
progress that has been made. Our DSL for 2012 was 7.7%, although the three-year rolling
average was 11.9%. This reduction was achieved by taking steps to find and eliminate sources
of loss which included:
• Conducting an acoustic leak detection survey to pinpoint leaks on an estimated 24 miles
of water mains and repaired 10 leaks found on existing water mains.
• Investigating possible leak reports from the automated meter reading program and
repairing meter leaks.
• Systematically replacing old, rusty and leaky water pipes to maintain water quality and
provide adequate flow for fire protection.
Renton should be in compliance with the three-year rolling average DSL requirement of less
than 10%, by the beginning of 2014. Figure 3 shows the steady progress made with the WLCAP.

2) Our second goal,which was to limit the peak water day demand to 16.5 million gallons per
day (mgd), has been achieved each year. Our highest peak day demand occurred in 2006 and
has been on a fairly steady decline, Figure 4. This reduction has been achieved through local
and regional education. Promotion of water wise gardening and the five-steps to healthy
gardens have been included in newsletters,garden classes offered by Renton Solid Waste, and
festivals. Renton has also participated in regional campaigns. Public attitudes, behavior and
understanding have moved towards a more water wise perspective. Letting lawns go dormant,
planting appropriately for the site, modifying when and how they water, and building healthy
soils have all helped reduce summer water consumption.

3) The third WUE goal set in 2007 was to continue the historical trend of reduction in domestic
water use per connection by one-half(0.5%) percent per year. Although annual water
consumption varies greatly dependent on summer rainfall and temperature, Figure 5 shows
that the trend for the average annual domestic water use per connection has been an overall
decrease of 176 percent, meeting and exceeding our goal.

Proposed 2013—2018 Water Use Efficiency Goal
It is proposed that the City of Renton adopt the six-year regional Water Use Efficiency goal:
"reduce per capita water use from current levels so that the total average annual retail water
use of the members of the Saving Water Partnership is less than 105 MGD from 2013 through
2018 despite forecasted population growth."
A new goal must be adopted every six years,for Renton that means by November 2013. The
Saving Water Partnership (SWP) collaborates to set a single regional goal for SWP members.
Renton became a member of the SWP in 2012 and has been participating in their programming.
The proposed goal will be implemented through targeting of the following six customer
program areas with specific measures and actions.
• Communications
• Youth and Community Education
• Landscape
• Landscape Irrigation Efficient Equipment
• Residential Indoor Efficient Equipment
• Industrial, Commercial, and Institutional Efficient Equipment
These targeted customer groups will be addressed with the following nine customer water use
efficiency strategies:
• Promote water efficiency among residential, commercial, institutional customers in a
fair and cost effective manner using education, training, partnerships, and financial
incentives.
• Increase youth participation in water conservation education by assessing what's
working well in school districts and expanding it throughout the region.
• Conduct outreach to communities to provide materials and information on leak
identification and repair, including multi-language "how-to" videos.
• Provide information and low cost giveaway items for community events,festivals, and
customer service counters.
• Explore new options to improve conservation communications, especially with non-
English speaking customers.
• Create a seasonal on-line conservation message repository for utility newsletters and
other communications.
• Promote changes in behavior that will lead to more water-efficient practices.
• Monitor and encourage a customer ethic that values water conservation.
• Comply with State Water Use Efficiency Rule.
Details of each of these six targeted programs are presented in the 2013-2018 Water
Conservation Strategies and Actions document: Preserving the Customer Conservation Ethic:
2013-2018 Regional Water Conservation Strategies and Actions of the Saving Water
Partnership. Located at: http://www.savingwater.orq/docs/2013WaterConsProgActionsStrategies.pdf
Individual programs are presented in Table 2. Current and Proposed Efficiency Activities.

SUBJECT: 2013 Water Use Efficiency Goal Setting
ISSUE:
Should Council approve the 2013 update of the City's Water Use Efficiency goal as
required by the Municipal Water Law under WAC 246-290-830?
RECOMMENDATION:
Adopt the 2013 Water Use Efficiency goal, following comments from a public meeting to
be held on Monday, October 14, 2013 at 7:00 p.m., at Renton City Hall.
BACKGROUND SUMMARY:
The Municipal Water Law requires the City to update its Water Use Efficiency (WUE)
goals every six years. The original City's WUE goals were adopted by Council on
November 19, 2007;therefore the next update of the goals must be adopted by Council
by November 19, 2013.
The 2007-2013 WUE goals were:
• Reduce distribution system leakage to 10%or less by 2010
• Limit the peak day water demand at 16.5 million gallons per day until 2015
• Continue reduction of average annual water use by 0.5%per year, per
connection
The City has met the initial WUE goals through the implementation of several water
conservation measures and capital programs including:
• Incentives and financial rebates to customers for water conservation efforts
• Adoption of a three-tiered water rate structure promoting water conservation
• Leak detection and repair program and an annual water main replacement
program
-row visor
Mr.Corman,President
Page 2 of 2
September 11,2013
• Implementation of an automated meter reading program with leak detection
capability and early notification to customers
The proposed 2013 - 2018 WUE goal:
In January 2012, the City of Renton entered into a 50-year(2012-2062) water supply
contract with Seattle Public Utilities (SPU) to purchase additional water from Seattle, if
needed, to supplement the City's own supply to meet anticipated water demand from
population and development growths until 2062. As a part of this contract, the City
agreed to become part of the SPU's purveyors'group, the Saving Water Partnership
(SWP), and participate in the group's conservation programs. SWP collaborated to set a
single regional goal for SWP members. Renton's conservation goal must now include
the SPU regional conservation goal as part of its own.
The regional WUE goal is:
"Reduce per capita water use from current levels so that total average annual retail
water use of members of the Saving Water Partnership is less that 105 million gallons
per day (mgd) from 2013 through 2018 despite forecasted population growth."
The proposed goal will be implemented through targeting of the following six customer
program areas with specific measures and actions:
• Communications
• Youth and Community Education
• Landscape
• Landscape Irrigation Efficient Equipment
• Residential Indoor Efficient Equipment
• Industrial, Commercial, and Institutional Efficient Equipment
CONCLUSION:
Council's adoption of the 2013 Water Use Efficiency goal is necessary in order for the
City to remain in compliance with the requirements of the Municipal Water Law.
The proposed goal is consistent with the goal of the regional water conservation
coalition and the Saving Water Partnership.

Water Use Efficiency Program
Information Packet for 2013 Goal Setting Meeting
The Water Use Efficiency Rule
Background
The State of Washington adopted the Municipal Water Supply-Efficiency Requirements Act,
commonly called the Municipal Water Law (MWL) or the Water Use Efficiency Rule in 2007. To
meet the requirements of this new rule, the City of Renton developed Water Use Efficiency
(WUE)goals, which were approved by the City Council on November 19, 2007.
The MWL is intended to help meet the growing needs of communities, agriculture, industry,
and to conserve water for fish. The rule is intended to help:
• Provide more certainty and flexibility for water rights held by water systems.
• Improve the ability to plan for future growth.
• Offer greater flexibility to solve public health problems with water right changes and
transfers.
• Advance water use efficiency.
• • Assure greater reliability of safe drinking water for communities.
What are the requirements of this rule? -
The rule requires municipal water suppliers, such as Renton to use water efficiently and
demonstrate that they are doing so. Specifically,water systems must:
• Develop goals through a public process and enact WUE measures to manage water use.
• Reduce water system leakage to 10 percent or less.
• Install meters on all customer connections by 2017 to accurately account for water use
and leakage.
• Report annually on their progress in using water efficiently.
How will this affect Renton?
To comply with this rule, we are:
• Conducting a water system audit that will allow us to account for all water used.
• Setting goals for water use efficiency through a public process.
• Re-evaluating our water supply and our forecasts for future water demands.
• Reporting each year on our progress toward these goals as part of the Consumer
Confidence Report we send to all customers.

Renton's Water
Water Supply Characteristics
All of our drinking water comes from groundwater. Based on production of the last five years,
about 85 percent of our drinking water is supplied by five wells located in downtown Renton,
which is pumped from a source known as the Cedar Valley Aquifer. Approximately 14 percent
comes from Springbrook Springs,which is located at the south end of the City. These water
sources are very clean and need minimal treatment.
The City also pumps from three deep wells known as the Maplewood well field located under
the Maplewood golf course. These wells are a backup water source and, as such, are not
utilized continuously. The Maplewood water is also very clean, but because of its natural
mineral content, it must first be treated before it can be co-mingled with the water from the
other sources.
In January 2012, Renton signed a long-term agreement (2012—2062) with Seattle Public
Utilities to purchase water. This water will assure that the City has a secure supply of water,
especially during peak summer usage periods. During the first year of 2012,the City bought 3.1
million gallons of supplemental water from Seattle, which represents 0.01%of the year's water
supply.
Water Use Characteristics
The City's customer and water use characteristics are important considerations for identifying
WUE objectives, goals and measures.
Who uses the water?
The Renton Water Utility provides water for an estimated population of 62,100 in its retail
water service area. The rest of Renton citizens receive water from surrounding water
providers. Renton provides water to approximately 15,505 residential customers and 1,917
non-residential (commercial, industrial, government and schools) customers. In 2012, the City's
customers used an average of 6,483,012 gallons a day.
As shown in Figure 1, single-family residential customers, who made up 79 percent of total
system connections, consumed 35 percent of total retail water sales. The multi-family
residential customer class accounted for 10 percent of system connections and 22 percent of
water use. Commercial users account for six percent of all system connections and use 18
percent of all water consumed. Industrial customers account for less than one percent of
system connections and two percent of water use. While only four percent of the total number
of accounts, irrigation use accounted for 13 percent of total water used. Wholesale water to
Skyway, SPU water to Boeing, and water consumption at the King County Wastewater
Treatment Plant site accounted for roughly eight percent of the City's consumption.

Water System Plan Update
City of Renton
When does the water get used?
Water consumption is closely related to the weather. Year to year variations reflect drought
years, hot years or wet years. The largest variations in water use are seasonal. Typically in
Renton, the highest water use is during the period of June through October. During these five
months, the average monthly water consumption is about 45 percent higher than the other
seven months of the year. The average day consumption in 2012 was 6.48 million gallons. The
peak day use in 2012, which occurred on September 7, was 11.46 million gallons. The increased
summer consumption is due primarily to irrigation. The current automated meter reading
project, that is underway, will allow finer detail about the timing of water consumption.
Water Demand Forecast
The City's future water demand is estimated based on current use and anticipated growth
within the Renton Water System Area (RWSA), utilizing data provided in the Puget Sound
Regional Council's (PSRC's) Population, Households,and Employment Forecast database.
In general,there is very little vacant land within the City's current RWSA; consequently, the
growth capacity within the City's RWSA is limited. The majority of future growth is projected to
occur within the Regional Urban Center and the Sunset Area Community Planned Action
redevelopment boundaries. Projections of the average and maximum daily demands through
2071 are shown in Figure 2.

Current Water Use Efficiency Program
Current (2007—2013)Goals
Our current, adopted November 19, 2007, Water Use Efficiency goals are:
1) Reduce distribution system leakage (DSL)to ten percent or less by 2010.
2) Cap the peak day demand at 16.5 mgd until 2015.
3) Continue reduction of average annual water use by 0.5 percent per year.
Goal Achievements
1) Our first goal addressed distribution system losses. The Municipal Water Law requires that
DSL be 10 percent or less based on a three-year rolling average. If a system's losses exceed this,
then it must develop a Water Loss Control Action Plan (WLCAP). Because our DSL in 2007 was
above 10%, a WLCAP was developed and began in 2008. The following figure shows the
progress that has been made. Our DSL for 2012 was 7.7%, although the three-year rolling
average was 11.9%. This reduction was achieved by taking steps to find and eliminate sources
of loss which included:
• Conducting an acoustic leak detection survey to pinpoint leaks on an estimated 24 miles
of water mains and repaired 10 leaks found on existing water mains.
• Investigating possible leak reports from the automated meter reading program and
repairing meter leaks.
• Systematically replacing old, rusty and leaky water pipes to maintain water quality and
provide adequate flow for fire protection.
Renton should be in compliance with the three-year rolling average DSL requirement of less
than 10%, by the beginning of 2014. Figure 3 shows the steady progress made with the WLCAP.

2) Our second goal,which was to limit the peak water day demand to 16.5 million gallons per
day (mgd), has been achieved each year. Our highest peak day demand occurred in 2006 and
has been on a fairly steady decline, Figure 4. This reduction has been achieved through local
and regional education. Promotion of water wise gardening and the five-steps to healthy
gardens have been included in newsletters, garden classes offered by Renton Solid Waste, and
festivals. Renton has also participated in regional campaigns. Public attitudes, behavior and
understanding have moved towards a more water wise perspective. Letting lawns go dormant,
planting appropriately for the site, modifying when and how they water, and building healthy
soils have all helped reduce summer water consumption.

3) The third WUE goal set in 2007 was to continue the historical trend of reduction in domestic
water use per connection by one-half(0.5%) percent per year.Although annual water
consumption varies greatly dependent on summer rainfall and temperature, Figure 5 shows
that the trend for the average annual domestic water use per connection has been an overall
decrease of 176 percent, meeting and exceeding our goal.

Proposed 2013—2018 Water Use Efficiency Goal
It is proposed that the City of Renton adopt the six-year regional Water Use Efficiency goal:
"reduce per capita water use from current levels so that the total average annual retail water
use of the members of the Saving Water Partnership is less than 105 MGD from 2013 through
2018 despite forecasted population growth."
A new goal must be adopted every six years, for Renton that means by November 2013. The
Saving Water Partnership (SWP)collaborates to set a single regional goal for SWP members.
Renton became a member of the SWP in 2012 and has been participating in their programming.
The proposed goal will be implemented through targeting of the following six customer
program areas with specific measures and actions.
• Communications
• Youth and Community Education
• Landscape
• Landscape Irrigation Efficient Equipment
• Residential Indoor Efficient Equipment
• Industrial, Commercial, and Institutional Efficient Equipment
These targeted customer groups will be addressed with the following nine customer water use
efficiency strategies:
• Promote water efficiency among residential, commercial, institutional customers in a
fair and cost effective manner using education,training, partnerships, and financial
incentives.
• Increase youth participation in water conservation education by assessing what's
working well in school districts and expanding it throughout the region.
• Conduct outreach to communities to provide materials and information on leak
identification and repair, including multi-language "how-to"videos.
• Provide information and low cost giveaway items for community events, festivals, and
customer service counters.
• Explore new options to improve conservation communications, especially with non-
English speaking customers.
• Create a seasonal on-line conservation message repository for utility newsletters and
other communications.
• Promote changes in behavior that will lead to more water-efficient practices.
• Monitor and encourage a customer ethic that values water conservation.
• Comply with State Water Use Efficiency Rule.
Details of each of these six targeted programs are presented in the 2013-2018 Water
Conservation Strategies and Actions document: Preserving the Customer Conservation Ethic:
2013-2018 Regional Water Conservation Strategies and Actions of the Saving Water
Partnership. Located at: http://www.savingwater.orq/flocs/2013WaterConsProcgActionsStrategies.pdf

When does the water get used?
Water consumption is closely related to the weather. Year to year variations reflect drought
years, hot years or wet years. The largest variations in water use are seasonal. Typically in
Renton,the highest water use is during the period of June through October. During these five
months,the average monthly water consumption is about 45 percent higher than the other
seven months of the year. The average day consumption in 2012 was 6.48 million gallons. The
peak day use in 2012,which occurred on September 7,was 11.46 million gallons. The increased
summer consumption is due primarily to irrigation. The current automated meter reading
project,that is underway,will allow finer detail about the timing of water consumption.
Water Demand Forecast
The City's future water demand is estimated based on current use and anticipated growth
within the Renton Water System Area (RWSA), utilizing data provided in the Puget Sound
Regional Council's (PSRC's) Population, Households,and Employment Forecast database.
In general,there is very little vacant land within the City's current RWSA;consequently,the
growth capacity within the City's RWSA is limited. The majority of future growth is projected to
occur within the Regional Urban Center and the Sunset Area Community Planned Action
redevelopment boundaries. Projections of the average and maximum daily demands through
2071 are shown in Figure 2.

Current Water Use Efficiency Program
Current(2007—2013)Goals
Our current, adopted November 19,2007, Water Use Efficiency goals are:
1) Reduce distribution system leakage(DSL)to ten percent or less by 2010.
2) Cap the peak day demand at 16.5 mgd until 2015.
3) Continue reduction of average annual water use by 0.5 percent per year.
Goal Achievements
1) Our first goal addressed distribution system losses. The Municipal Water Law requires that
DSL be 10 percent or less based on a three-year rolling average. If a system's losses exceed this,
then it must develop a Water Loss Control Action Plan(WLCAP). Because our DSL in 2007 was
above 10%, a WLCAP was developed and began in 2008. The following figure shows the
progress that has been made. Our DSL for 2012 was 7.7%,although the three-year rolling
average was 11.9%. This reduction was achieved by taking steps to find and eliminate sources
of loss which included:
• Conducting an acoustic leak detection survey to pinpoint leaks on an estimated 24 miles
of water mains and repaired 10 leaks found on existing water mains.
• Investigating possible leak reports from the automated meter reading program and
repairing meter leaks.
• Systematically replacing old, rusty and leaky water pipes to maintain water quality and
provide adequate flow for fire protection.
Renton should be in compliance with the three-year rolling average DSL requirement of less
than 10%, by the beginning of 2014. Figure 3 shows the steady progress made with the WLCAP.

2) Our second goal,which was to limit the peak water day demand to 16.5 million gallons per
day(mgd), has been achieved each year. Our highest peak day demand occurred in 2006 and
has been on a fairly steady decline, Figure 4. This reduction has been achieved through local
and regional education. Promotion of water wise gardening and the five-steps to healthy
gardens have been included in newsletters,garden classes offered by Renton Solid Waste,and
festivals. Renton has also participated in regional campaigns. Public attitudes, behavior and
understanding have moved towards a more water wise perspective. Letting lawns go dormant,
planting appropriately for the site, modifying when and how they water,and building healthy
soils have all helped reduce summer water consumption.

3) The third WUE goal set in 2007 was to continue the historical trend of reduction in domestic
water use per connection by one-half(0.5%) percent per year.Although annual water
consumption varies greatly dependent on summer rainfall and temperature, Figure 5 shows
that the trend for the average annual domestic water use per connection has been an overall
decrease of 176 percent, meeting and exceeding our goal.

The sources of these savings are the result of variety of efforts. Table 1 presents the
"hardware"efforts that the City has employed since adopting our current goals in November
2007.

Proposed 2013—2018 Water Use Efficiency Goal
It is proposed that the City of Renton adopt the six-year regional Water Use Efficiency goal:
"reduce per capita water use from current levels so that the total average annual retail water
use of the members of the Saving Water Partnership is less than 105 MGD from 2013 through
2018 despite forecasted population growth."
A new goal must be adopted every six years,for Renton that means by November 2013. The
Saving Water Partnership (SWP) collaborates to set a single regional goal for SWP members.
Renton became a member of the SWP in 2012 and has been participating in their programming.
The proposed goal will be implemented through targeting of the following six customer
program areas with specific measures and actions.
• Communications
• Youth and Community Education
• Landscape
• Landscape Irrigation Efficient Equipment
• Residential Indoor Efficient Equipment
• Industrial, Commercial, and Institutional Efficient Equipment
These targeted customer groups will be addressed with the following nine customer water use
efficiency strategies:
• Promote water efficiency among residential, commercial, institutional customers in a
fair and cost effective manner using education,training, partnerships,and financial
incentives.
• Increase youth participation in water conservation education by assessing what's
working well in school districts and expanding it throughout the region.
• Conduct outreach to communities to provide materials and information on leak
identification and repair, including multi-language "how-to"videos.
• Provide information and low cost giveaway items for community events,festivals, and
customer service counters.
• Explore new options to improve conservation communications,especially with non-
English speaking customers.
• Create a seasonal on-line conservation message repository for utility newsletters and
other communications.
• Promote changes in behavior that will lead to more water-efficient practices.
• Monitor and encourage a customer ethic that values water conservation.
• Comply with State Water Use Efficiency Rule.
Details of each of these six targeted programs are presented in the 2013-2018 Water
Conservation Strategies and Actions document: Preserving the Customer Conservation Ethic:
2013-2018 Regional Water Conservation Strategies and Actions of the Saving Water
Partnership. Located at: http://www.savinawater.orq/docs/2013WaterConsProgActionsStrategies.pdf
Individual programs are presented in Table 2.Current and Proposed Efficiency Activities.
