Washington State Department of Health Northwest Regional Office 20425 72nd Avenue South, Suite 310 Kent, WA 98032 RE: City of Auburn 2015 Water System Plan (Water System ID 03350) Approval Extension Request Dear Mr. Rodriguez: On behalf of the City of Auburn, I am requesting approval of a 4-year extension for the City of Auburn Water System Plan (WSP), entitled "City of Auburn Comprehensive Water Plan, October 2015". On May 11, 2016, the Washington State Department of Health approved the City's WSP fora 6-year term that will expire on May 11, 2022. To date, there have been no significant changes to the WSP that warrants the scheduled approval update per WAC 246-290-100. The projects, demands and growth presented in the current WSP are still valid and are accurate projections of the City's current planning efforts. Additionally, the current WSP includes projects, demands and growth projections 4 years beyond the 6-year planning period in anticipation of this extension request. Although the City is requesting a 4-year extension, a full water system plan will be prepared as part of the City-wide comprehensive plan, expected to be completed in 2024. SYSTEM CAPACITY Demand The City's annual water demand between 2014 and 2020 has been less than the projected demand in the City's 2015 WSP for each corresponding year. Table 1 and Figure 1 show the difference between the projected average day demand (ADD) and maximum day demand (MDD) in the 2015 WSP, and the actual ADD and MDD for the years 2015 through 2020. With conservation, low distribution system leakage, and Lake Meridian securing an alternate wholesale source so that it has not been utilizing wholesale water from Auburn, the City expects to remain below the demands shown in 2015 WSP Table 4.17 and Figure 4.8 through 2025.

At the end of the 6-year cycle, a new goal was established through a public process. The new 2021-2025 goal is anticipated to be adopted by the City Council on August 2, 2021. The projected demands that were calculated for the 2015 WSP update using historical water production, purchase, sales data, and the growth projection data were used to support the new goal. 2021-2025 WUE Goal: Decrease the planning ERU value (gpd/ERU) 1 percent annually from the current planning ERU value of 179 gpd/ERU, which is the 75th percentile of 7 years of historical data (2014-2020). Revaluate goal when the planning ERU value reaches less than 172 gpd/ERU. ENG-163, Revised 12/18 Richard Rodriguez July 14, 2021 Page 3 of 9 The City plans to continue to implement 14 of the 15 demand-side WUE program measures noted in the 2015 WSP Section 8.2.5 to achieve the new 2021-2025 WUE goal. The Demonstration Garden (Measure 14) is no longer maintained because the location exacerbated homeless encampment issues. However, a new program measure described below is proposed, keeping the total number of program measures at 15. Rainwater Harvesting: The City will evaluate implementation of a rainwater harvesting (rainwater reclamation) promotion program as a means to reduce irrigation water usage by commercial, public and residential customers. The City Stormwater Utility's requirement to use Low Impact Development (LID) measures, where feasible, strives to keep rainwater on the property, further reducing irrigation demands. Storage 2015 WSP analysis identified storage deficiencies in the Valley and Lea Hill service areas in 2035. A combination of storage and supplies are needed to eliminate these deficiencies. Long-term capital projects to install iron and manganese treatment at Well 7 and construct a new Valley storage reservoir will eliminate the deficiencies when completed. These projects remain in the Capital Improvements Plan in the mid-term and long-term planning. CAPITAL IMPREOVMENT PLAN The City has made progress in completing the following capital improvements per the schedule outlined in Chapter 10 of the 2015 WSP. Listed below is a summary of the scheduled Capital Improvement Projects and/or Programs from the 2015 WSP Table 10.6 that were completed or are still in progress. Most water main replacement projects are not identified individually in the 2015 WSP. They are included in the Street Utility Improvements Program, Water Repair and Replacement Program, and Annual Distribution Improvements Program.

For purposes of projecting growth over the next 5-year period, the service area represents approximately 75% of the City's corporate boundaries, taking into account areas are not developed or are served by private wells that are not expected to connect to the water system within the next 5 years. The 2015 WSP Table 4.8 projected a total service area population of 57,213 for 2015 and 62,581 for 2021. The State Office of Financial Management (OFM) population estimates are presented in Table 3. The total population of the City is the sum of the parts in.King and Pierce Counties, with calculated water service area population 75% of the total. • Table 3 City of Auburn Population: • ) i 20101 2015; 20161 2017 20181 20191 2020 Population: Population1 Population; Population Population; Population; Population County Jurisdiction !

It is anticipated the actual growth in demand over the requested 4-year extension period will not exceed the demand projections stated in the 2015 WSP. POLICIES AND DESIGN CRITERIA The City's water service policies as presented in Section 3 of the 2015 WSP have remained the same for operating and constructing new facilities. The Design and Construction Standards provided in Appendix Q of the 2015 WSP have had minor modifications to provide clearer information or revised materials specifications. The water sections of the City of Auburn Design and Construction Standards are attached. FINANCING AND IMPLEMENTATION The financial analysis in Section 11 of the 2015 WSP identified the capital improvement plan (CIP)that the City is currently still pursuing. The City continues to fund the water • operations and CIP programs while still maintain positive reserves as indicated in Table 4. The City obtained bond funding in 2020 for approximately$13.7 million for some of the planned projects. This funding was anticipated and discussed in the 2015 WSP Chapter 11. The City has adequate reserves to fund its debt service. ENG-163, Revised 12/18 Richard Rodriguez July 14, 2021 .

Water Right Permit, Certificate, or Claim Number:This number is assigned by Ecology when a permit application is filed. It's listed at the top of the permit or certificate. For water right claims, this is the registration number stamped in the lower left hand corner of the claim form. WH Source#: Identify the individual sources (e.g.well #1,well #2) as defined on the DOH Water Facilities Inventory form. If a water right is associated with multiple sources, list all sources in the same row in this column. If a source is associated with multiple water rights, identify each water right on a separate row. If you have any source(s) that is not currently being used (categorized as standby, back-up, or emergency), and the source has an associated water right that is not listed in column #1, please include the source and water right information in the ADDITIONAL COMMENTS section.This will identify that the source is still intended for a beneficial use under RCW 90.03.015(4). See Ecology Policy 1040.

This section refers to existing water rights. It does not include any water right applications that have been submitted to Ecology. Primary Qi (Instantaneous Quantity):This is also known as instantaneous flow rate. It's the amount of water allowed to be taken under the right from the source during a period of peak operation. For surface water, this is generally expressed in terms of cubic feet per Page 2 of 6 second (cfs). For groundwater, this is generally expressed in terms of gallons per minute (gpm). One cfs equals 448.8 gpm. Please indicate the units of measurement you are using for each source. If there are situations where the flow rate will be limited (e.g. limitations established on the source when other sources are utilized), please note them in the ADDITIONAL COMMENTS section in the form and in the WSP narrative. Non-Additive Qi:This term was formally known as "supplemental."Your water rights may use the old terminology. See Ecology Policy 1040 for more information. Not all water rights have non-additive quantities. If a water right has non-additive Qi quantities, include the non- additive quantity in this field. This is generally listed in the "quantity, type of use, period of use" section on both permits and certificates. Non-additive quantities should not be included in the primary Qi totals. Primary Qa (Annual Quantity):This is the amount of water that can be taken from the source under the right on an annual basis. It's usually expressed in terms of acre-feet. An acre-foot is the amount of water necessary to submerge an acre of land to a depth of one foot. One acre-foot equals 43,560 cubic feet or 325,851 gallons of water. Non-Additive Qa:This term was formerly known as "supplemental." Your water rights may use the old terminology. See Ecology Policy 1040 for more information. Not all water rights have non-additive quantities. If a water right has non-additive Qa quantities, include the non-additive quantity in this field.This is generally listed in the "quantity, type of use, period of use" section on both permits and certificates. Non-additive quantities should not be included in the primary Qa totals. CURRENT SOURCE PRODUCTION SECTION (light green color, top section) This section refers to how much water is withdrawn from the source under each water right for the most recent full calendar year.You will need to determine any excess or deficiency for each water right after calculating how much water was withdrawn compared to how much water is allowed under each water right. If demand has decreased over past years, you may wish to include historic maximum production information in the ADDITIONAL COMMENTS section.This will provide a more complete picture of the use of your water rights. Use the water use data and demand projections from your water system plan to define current and projected water needs.You can determine if you'll need additional water rights based on the comparison of existing water rights, current water production, and projected 10- and 20- year needs. Total Qi (Instantaneous Quantity): This refers to the total maximum instantaneous flow rate withdrawn from the source under each water right during the most recent calendar year. For surface water, this is expressed in terms of cubic feet per second (cfs). For groundwater, this is expressed in terms of gallons per minute (gpm). One cfs equals 448.8 gpm. Page 3 of 6 Current Excess or Deficiency (Qi): Please calculate the excess or deficiency for each water right after comparing the total amount withdrawn against each water right. Please use parentheses for deficient amounts. Total Qa (Annual Quantity):This refers to the total volume of water withdrawn from each source under each water right during the most recent calendar year. It's usually expressed in acre-feet. Current Excess or Deficiency (Qa): Please calculate the excess or deficiency for each water right after comparing the total amount withdrawn against each water right. Please use parentheses for deficient amounts. 10-YEA11.EC}RECASTED SOURCE PRODUCTIDNi'SEC "ION (light blue color, top section) This section refers to how much water you project to withdraw from each source in ten years as determined in your water system plan. Please complete this section in the same manner(using the same units of measurement) as the current source production section using your 10-year forecasted amounts. 2 B YEAR;FORECASTED SOURCE PRoDUCTIC}N9 SECTIONS (darker blue color, top section) This section refers to how much water you project to withdraw from each source in twenty years as determined in your water system plan. Please complete this section in the same manner (using the same units of measurement) as the current source production section using your 20- year forecasted amounts. If you are unable to provide 20-year forecasts for each source, you may choose to include the combined 20-year total at the bottom. pEitlDING WATER RIGHTS SECTION (second section of form) Please complete this section for any water right applications that have been submitted to Ecology. Please include the application number,whether it's a new or a change application, the date submitted, and the total quantities requested. INI 'ERTIIES SECTiD (third section of form] This section must be completed by purveyors who purchase any amount of wholesale water. If your system sells water to another public water system, include the quantity sold in the CURRENT SOURCE PRODUCTION section. Purchasers of wholesale water must account for all water obtained through the intertie for non- emergency supply purposes. This is to ensure that all sources of supply are considered when evaluating whether new water rights are needed within 20 years. Please identify the maximum quantity of water, expressed in the same manner as the above sections, allowed under each intertie contract. If there are limiting conditions or temporary Page 4 of 6 agreements that effect the long-term use of the intertie, you must account for such limiting conditions when evaluating the current and forecasted water supply needs in your water system plan. Finally, purchasers of wholesale water are responsible for ensuring that the underlying water right (held by the purveyor selling water) are adequate for such use.You should confirm that the selling system has accounted for the wholesale area in their water system plan to ensure that the water right authorizes the distribution of water through the intertie. INTERRU TI LE WATER RIGHTS SECTION (bottom sect�an of form) This section refers to water rights that have an annual time-of-year interruption. Please complete this section for.any water right listed in the above fields that has a time-of-year interruption. Please include the water right number, describe the limitation, and the time period of interruption. Purveyors with interruptible rights should develop a water shortage response plan as part of their water system plan to describe how demand will be met during periods of . interruption through aggressive demand-side conservation, fixing leaks or other means. ADDITIONAL COMMENTS SECTION (bottom section of form) If the system has any source that is not currently being used on a regular basis (such a source may be categorized as stand-by, back-up, emergency), you should identify the source in this section if the source has an associated water right that is not listed in the above sections. The purpose is to identify that such water rights are still intended for a future beneficial use as required under RCW 90.03.015(4). See Page 2, Item 9 (b) in ECY Policy 2030. For these water rights, please briefly describe the future intended use of the source and when you expect to utilize the water right. This does not refer to sources categorized as seasonal sources. You should also include any other comments in this section that will explain aspects of your water right portfolio that are not identified above.

Efficient water use is critical for water systems to support growth in their communities and support the environment and recreation. The efficient use of water helps ensure reliable water supplies are available for the City of Auburn (City)well into the future. It is important to the City to not only conserve water, which reduces use, but also promote efficient use, which both conserves water and reduces wasteful uses. The purpose of this document is to provide an analysis of the City's historic water conservation program and to evaluate the existing and proposed conservation and water use efficiency measures. This document is formatted into two sections. The first section analyzes the previous conservation programs by examining how it was formed, it's program and goals, and analyzes the savings. The second section presents the City's new 2021 Water Use Efficiency (WUE) Program, and includes the new requirements, measures, and demand savings anticipated from the program. 1 PRIOR CONSERVATION PROGRAMS 1.1 History The first formal water conservation program was developed by the City in 1995, one year after the Washington Department of Health (DOH)jointly published conservation guidelines, as described below. The City's program included several conservation activities such as . school outreach, program promotion, leak detection, meter repair/replacement, and conservation pricing. The City enhanced the program in 2001, 2009, and in 2015. The 2015 program will provide the basis of the historical review in this chapter. The City's 2021 WUE Program follows DOH's 2017 Water Use Efficiency Guidebook, while building off previous plans. Therefore, it is worth noting that in preparing previous plans the City reviewed the 1990 South King County Coordinated Water System Plan (CWSP), and Washington Department of Ecology's 1994 Conservation Planning Requirements (CPR) - Guidelines and Requirements for Public Water Systems Regarding Water Use Reporting, Demand Forecasting Methodology, and Conservation Programs, and the Water Conservation Bibliography for Public Water Systems by the US Army Corps of Engineers. 1.2 Regulatory Requirements The Washington Water Utilities Council, DOH, and Department of Ecology jointly developed the CPR. Interim guidelines were first established in 1990, and subsequently finalized and approved in 1994. The DOH published the CPR in 1994, which was the basis of the City's 1995 and 2001 conservation programs. July 2021 —DRAFT 1 In 2003, the Washington State Legislature passed Engrossed Second Substitute House Bill 1338, better known as the Municipal Water Law, to address the increasing demand on our state's water resources. The law established that all municipal water suppliers must use water more efficiently in exchange for water rights certainty and flexibility to help water municipal suppliers meet future demand. The Legislature directed the DOH to adopt an enforceable WUE Program, which became effective on January 22, 2007. The WUE Program replaced the CPR, and emphasizes the importance of measuring water usage and evaluating the effectiveness of the water supplier's WUE Program. 1.3 Previous Program Goals and Historical Water Usage The City's 2015-2020 WUE Program was a continuation of the 2009-2014 Program, with specific enhancements to the program to comply with WUE regulations and create an emphasis on efficient water usage rather than only conservation. The program goals were set per the WAC 246-290-830(4)(a)through a public process and posted to the City's website in October 2014. The goals for the 2015-2020 Program targeted a 1 percent reduction per year in Equivalent Residential Unit (ERU) values. The City also wanted to raise the visibility and performance of the Conservation Program by becoming a community leader in water conservation through example and public education. As part of that leadership, the City supported and participated in applicable regional plans in order to maintain a reliable and adequate supply of water for the region. In 2013, the planning ERU value was 195 gpd per ERU, based on the 75th percentile of the previous six years of data. The 2020 (current) planning ERU value is 179 gpd per ERU, which was also based on the 75th percentile of the previous seven years of data. This equates to a 1.1 percent annual decrease in the planning ERU value. The annual water use per Single Family account from 2014 through 2020 used to calculate the planning ERU value is shown in Table 1. Table 1 Historical Annual Water Use Per Account (gpd/account) Year I Single Family/Duplex 2014 174 2015 179 2016 170 2017 176 2018 193 2019 169 2020 179 Average 177 75th percentile 179 ERUs per Account 1.0 July 2021 —DRAFT 2 Seasonal water use can have a huge impact on the system's ability to deliver water during peak demands. The winter months generally show a steady monthly usage, while summer months typically show an increase, peak, and decrease in water usage. Historically, single- family residential customer class has produced a large peak in the summer months. This peaking is quantified in the MDD to ADD peaking factor presented in Table 2. The 75th percentile of the MDD to ADD peaking factor for the period between 2012 and 2020 is 1.85, which is slightly above the previous plan of 1.82. The City would like to decrease peak use and has included it as a new goal in the 2021-2025 WUE Program.

It is calculated as the difference between the total amount of water produced and the sum of water sold and authorized unmetered water usage. It may include inaccurate master and service connection meters, unaccounted-for non-revenue water use, pipeline leakage, and unauthorized use. DSL does not include authorized water usage such as water used for fire protection, flushing, construction, and other maintenance and operations practices. However, to be credited, this must be accounted for by metering or by estimating water use with credible means. All water that is not authorized is considered distribution system leakage. The DOH requires the 3-year average DSL to be under 10 percent to minimize water waste. The historical 3-year rolling average DSL ranged between 3.4 percent and 9.7 percent for the period from 2013 to 2020. July 2021 -DRAFT 3 2 2021-2025 WATER USE EFFICIENCY PROGRAM The 2021-2025 WUE Program will be a continuation of the City's current WUE Program. Program measures have been expanded, reflecting the City's increased service population of over 50,000 people. The program has also been updated to leverage the City's investments in improved SCADA, leak detection, and Advanced Metering Infrastructure (AMI). The 2021 Plan complies with regulations as set forth in WAC 246-290-830 and DOH's 2017 Water Use Efficiency Guidebook. This section summarizes the program's goals, demand and supply side measures, reclaimed water, and DSL. The projected demand with the conservation goals, program budget, and cost savings are also presented. 2.1 Program Goals Per the WAC 246-290-830(4)(a), all water purveyors with 1,000 or more connections were required to set efficiency goals through a public process. The City has chosen to focus on implementing voluntary measures to decrease both the average and peak water usage. The 2021 program has established the following goals: • Water Use per ERU: Decrease the planning ERU value (gpd/ERU) 1 percent annually from the current planning ERU value of 179 gpd/ERU, which is the 75th percentile of 7 years of historical data (2014-2020). Revaluate goal when the planning ERU value reaches less than 172 gpd/ERU. • MDD/ADD Peaking Factor: Decrease the planning peaking factor from the current 1.85, which is equal to the 75th percentile of 7 years of historical data (2014-2020), to a planning peaking factor of less than 1.72. • Distribution System Leakage: Maintain 3-year average DSL under 10 percent to minimize water waste. • Customer Support: To provide the service and support necessary to those water customers expressing a desire to conserve water as a part of their environmental ethic and as a means of minimizing water bills. • Regional Support: To support and participate in the South King County CWSP and other applicable regional plans in order to maintain a reliable and adequate supply of water for the region. The WUE Program measures, as summarized below, are designed to help meet these established goals. 2.2 Program Requirements • The WUE requirements emphasize the importance of measuring water usage and evaluating the effectiveness of the City's program. There are three fundamental requirements of a WUE Program that the City follows: July 2021 — DRAFT 4 • Planning Requirements—Municipal water suppliers are required to: — Collect data. — Forecast demand. — Evaluate WUE measures. — Calculate DSL. — Implement a WUE Program to meet their goals. • Distribution Leakage Standard —Municipal water suppliers are required to meet a distribution system leakage standard to minimize water loss from their distribution system. • Goal setting and performance reporting—Municipal water suppliers are required to set WUE goals through a public process and report annually to their customers and DOH. 2.3 Mandatory Measures The WUE Program includes supply side measures that the City implements to understand and control leakage including new meters, leak detection surveys, and water audits. Per the WUE requirements, the following measures shall be continued for the 2021-2025 WUE program: • • Install production (source) meters. • Install consumption (service) meters. • Perform meter calibration. • Implement a water loss control action plan to control leakage if the 3 year rolling average exceeds 10 percent. • Educate customers about water use efficiency practices. • Establish rates that encourage water demand efficiency. See Chapter 11 of 2015 Comprehensive Water Plan for discussion on water rates. • Evaluate reclamation opportunities. 2.4 Distribution System Leakage DSL is a significant element in the City's WUE Program. In the past, distribution leakage was referred to as "unaccounted-for-water". To limit DSL, the City has ongoing leak detection, meter calibration, and an active repair and replacement program for water system infrastructure. Additionally, the City has recently increased its efforts to reduce non- payment of bills and water theft. Further, the City has updated its SCADA and implemented AMI during the 2015-2020 period. These investments significantly increase the City's ability to measure DSL both July 2021 —DRAFT 5 temporally and geographically. The resulting information allows the City to better target its WUE activities to reduce DSL. 2.4.1 Increasing Effectiveness of the WUE.Program with AMI The City implemented AMI throughout the system during the 2015-2020 program period. AMI provides a new tool to improve the effectiveness of the WUE Program measures. AMI provides detailed water use data for each customer that allows the City to better understand water use patterns and target WUE Program measures to specific customers. Data is sent 6 times each day and is stored in 15-minute intervals indefinitely. Below is a summary of how the City uses AMI. • Run continuous consumption reports daily to identify customer leaks. • Detect service leaks sooner resulting in reduced costs for Service Replacement program and Leak Detection program. • Use meter tamper and other daily alarms to reduce water theft. • Compare production and customer water use to calculate DSL on a monthly basis. • Implement a customer portal to provide additional reporting options to educate customers, such as their peak water use. 2.5 2015-2020 Demand-Side Program Measures The City has incorporated program measures that target reductions in customer usage, saving the customers money without reducing the quality of service. Under the WUE requirements, a program measure may include water efficient devices, actions, business practices, or policies that promote efficient water use. With 15 measures as part of the 2021 Program, the City exceeds the minimum DOH requirement of 12 measures. WUE measures can target specific customer classes or a combination of customer classes. The City's demand-side program measures are summarized below. 1. School Outreach: School programs will continue to be arranged to educate students on efficient water usage. The City has partnered with Nature Vision to provide classroom education for grades K through 12. This program provides hands-on activities to teach water conservation, water supply, groundwater and surface water protection, and the water cycle. The City will conduct alternative or additional outreach if requested by schools. 2. Speakers' Bureau: The City will seek speaking opportunities to discuss water use efficiency with a wide-audience spectrum. Topics could include water efficient fixtures and appliances, curbing seasonal peak demands, lawn watering practices, etc. 3. Program Promotion: The City will seek opportunities for public service announcements for water use efficiency, and submit news articles to local papers July 2021 —DRAFT 6 and Auburn City Magazine on efficient water usage especially during the spring and summer months. Additional information is published on the City's website 4. Theme Shows/Fairs: The City hosts an annual Kids Day fair. The fair includes a wide range of activities for all ages of kids. As part of the fair, the City has fun water related activities and provides water efficiency brochures and other materials. The City will conduct outreach at other Theme Shows/Fairs if requested. 5. Water Audits: The City will conduct a water audit upon the request of a customer, including industrial, commercial, and institutional customers. The audits will review items such as: recirculation of cooling water, reuse of cooling and process water, reuse of treated wastewater, efficient landscape irrigation, low water using fixtures, fixing leaks, and process modifications. 6. Customer Leak Detection: The City identifies potential leaks through investigation of the water meter upon request of customers. The City's AMI system identifies smaller leaks and allows the City to notify customers of a potential leak within a couple days of the leak starting. 7. Bills Showing Consumption History: The City will continue to provide customer bills showing the previous year's water usage. The City is evaluating AMI customer portal options that will educate customers on their water use, alert them to leaks in real time, and identify opportunities to reduce their peak water use to help the City meet its goal of reducing the MDD:ADD ratio. 8. Water Saving Device Kits: The City will participate in distribution of water use efficiency kits through education events such as speakers' bureaus, theme shows, fairs, and through bill insert request forms. 9. WUE Pricing: The City has an inverted block rate structure for single-family residential customers to encourage WUE. The City will consider WUE in future cost of service/rate studies. Studies will determine the most appropriate water structures and rate levels to achieve the City's WUE goals, while generating sufficient revenues for utility operations. The studies consider uniform rates by class, inverted block rates, seasonal rates, and excess use rates. 10. Water Efficient Toilet Rebate Program: The City will continue to provide rebates to customers that replace old toilets with new high-efficiency toilets through their EPA WaterSense Toilet Rebate program. 11. Low-Flow Shower Heads Giveaways: The City gives away free low-flow shower heads at the Utility Billing Counter. 12. School Outdoor Water Use Reduction: The City will target schools in an effort to reduce their outdoor water consumption. Water audits and education on benefits of replacing inefficient irrigation systems or landscaping (including turf)will be conducted. 13. City Water Use Reduction: The City will audit the water use of City accounts in an effort to identify both indoor and outdoor water saving opportunities. The Water Utility staff will help educate City account holders on WUE; however, no water budget has been allocated to implement water saving devices at City facilities. July 2021 —DRAFT 7 14. Landscape Workshops: The City will seek opportunities to educate homeowners on water saving landscaping. 15. Rainwater Harvesting: The City will evaluate implementation of a rainwater harvesting (rainwater reclamation) promotion program as a means to reduce irrigation water usage by commercial, public and residential customers. The City Stormwater Utility's requirement to use Low Impact Development (LID) measures, where feasible, strives to keep rainwater on the property, further reducing irrigation demands. WUE measures can result in savings in energy and cost, both for the City and its customers, as described below: • Reduced water use can result in significant customer energy savings because water heaters are the second largest energy users in the home. Hot water use can be reduced almost one-third by cost-effective WUE measures, such as water efficient fixtures and appliances. Significant energy savings can also occur for industrial processes requiring water heating and other power uses. • Efficient landscaping and irrigation techniques save on maintenance costs. • Reductions in water production decrease the energy costs incurred to treat and distribute water and to collect and treat wastewater. Chemical costs are also reduced in water and wastewater operations. • Actions that result in water production cost savings include: — Identification of non-revenue water could result in recovery of unbilled revenue from inaccurate meters and reduced unauthorized water usage (theft). — Leak detection helps prevent major main breaks, which could result in significant repair costs as well as lost water for sale. — Leak detection reduces the City's liability by preventing potential property damage. — Repair and/or replacement of service and source meters allows the City to recover unbilled water revenues. 2.6 Reclaimed Water According to WAC 246-290-100 and the WUE requirements, water systems with over 1,000 connections must collect and evaluate information on reclaimed water opportunities. The City is committed to wastewater reuse and rainwater reclamation. The City monitors opportunities for use of King County's reclaimed water through the City's involvement in the Metropolitan Water Pollution Abatement and Advisory Committee (MWPAAC) and Regional Water Quality Committee. Additionally, the City has completed the King County Water Reclamation Evaluation Checklist (see Appendix J in the 2015 Comprehensive Water Plan). Currently, there are no reclaimed water users in the City. The City considers the most likely users of reclaimed water to be the irrigation customer class. Total irrigation use July 2021 —DRAFT 8 just from dedicated irrigation meters for 2020 was 0.40 million gallons per day. Irrigation from residential customers was significantly more. The City has also identified that it may be possible for three large users to use reclaimed water(Boeing, Emerald Downs, and Supermall/Walmart); however, these users have not confirmed an interest in using reclaimed water and there is not currently a reclaimed water source in the area. The City will implement reclaimed water as a conservation measure and include this savings in the demand projections when specific opportunities arise.The City, in conjunction with King County, may develop projects or consider participation in water reuse projects and programs developed by adjacent jurisdictions and others as appropriate. The efforts may include demonstration or pilot projects developed in accordance with applicable federal, state, and local laws and regulations. 2.7 Budget The City has established a budget for outside expenditures for applicable program measures from 2021-2025, shown in Table 3. Program Measure budgets coincide with the biannual budget. Budgets increase by three to four percent on average over the period.

The report, which is also submitted to DOH, provides the City's DSL, date of most recent public forum, WUE goals, description of progress in reaching goals, and additional information on WUE efforts. The City website provides the last three years of Efficiency Reports allowing customers to compare performance between several years. The City's website also prominently displays its Conservation Promotions, including frequently asked questions and rebate forms, that are also available at the Utility Billing counter. The City has conducted a public process to establish its 2021-2025 WUE Program Effectiveness goals, which are outlined in the next section. A public meeting will be held on August 2, 2021 at 7:00 PM. Public comments were incorporated into the WUE goals, and are in the Appendix. 2.9 2015-2020 WUE Program Effectiveness The City's water use, both on average and peak demand days, has declined. An aggressive WUE Program is likely a major reason for this decline; however, it is difficult to estimate the actual water savings directly resulting from the City's WUE Program because the measures are not directly quantifiable. Measures such as rebates for high-efficiency toilets and low- flow showerheads, do have a direct water savings per device, but the water savings from installation of water saving devices without requests for rebates is impossible to measure. The impacts on customer water use as a result of public education, which is the main focus of the City's WUE Program, is challenging to measure, as the response of each participant varies greatly. 2.9.1 Future Methods for Measuring Program Effectiveness The existing program effectiveness was evaluated using system-wide historical water use data. Future program effectiveness may measure the effectiveness of the City's WUE July 2021 —DRAFT 10 Program based on targeted public education programs to customers in a particular area. This area could be limited to a particular pressure zone, group of neighborhoods, etc., but should be an area for which the City can track water use before and after participation in WUE activities or events. Winter months would provide an estimate on indoor water use, since outdoor water uses, such as irrigation, are kept to a minimum during the winter. Summer months could provide an estimate on total indoor and outdoor water use. The first step would be to establish a baseline from historical information.The second step would be to evaluate the resulting water use after promoting WUE through targeted activities and events to customers in the defined area. AMI wouldprovide additional capabilities to more easily perform these studies. The water use would be tracked for an additional year to identify seasonal trends. Some consideration would need to be given to variations in weather and economic conditions. Another method would be to perform the same before/after water use analysis for WUE Program participants who volunteer and provide their address. The resulting information would be valuable for the City to correlate its WUE Program efforts with direct water savings for its customers. 2.9.2 Cost Savings The WUE Program primarily provides cost savings in two ways. Reducing demand may reduce or delay capital projects for additional supply and expanded distribution infrastructure. Additionally, reducing DSL can provide additional revenue, as well as increase the efficiency of supplying existing water uses. The City has completed a cost analysis of their proposed WUE Program using historical data and projected annual water savings. The City has exceeded its WUE Program goal of five percent water use reduction from 2014 through 2020; the actual reduction was nine percent. However, significant portions of the water use savings may be attributed to the factors other than the WUE Program, such as the economy. To avoid over-estimating cost savings, it was assumed that the WUE Program only achieved its goal of five percent, rather than the 9 percent reduction; this corresponds to savings of 0.4 mgd of ADD from 2014 to 2020. The City will budget approximately$244,850.00 for the WUE Program in 2021. This budget includes both the WUE Program measures ($66,850.00), and the required measures, ($178,000.00). This annual expenditure is budgeted and expended through the City's operation and maintenance budget. Based on the projected 2021 budget and the estimated annual water savings of 0.06 mgd, projected unit cost of water from the City's program for 2021 is estimated to be$0.0112 per gallon on average. It is important to consider the majority of the WUE budget is for service line and meter replacements, which is a key Utility business practice to maintain accurate billing and payment. Without these costs, the estimated cost for each gallon of water saved by the WUE Program is only$0.0031 per gallon on average. Additionally, WUE plays an important role in reducing the need for new supplies and delaying costly distribution system upgrades. July 2021 —DRAFT 11 2.10 Projected Water Demand The WUE Program is only applicable to retail customers. Wholesale customer demand is not included in projections. The projected water demand for the Retail Water Service Area with and without WUE for the ADD and the MDD are presented in Table 5. Demands are presented for the 15-year planning period, as well as the Ultimate demand. The planning ERU value of 172 gpd/ERU is expected to be achieved in 2025 based on an annual one percent decrease. No further reductions in demand are projected beyond 2025. Figure 1 is a graphical representation of the data in Table 5.

As shown in the table, WUE measures are projected to result in a reduction in retail MDD of 1.69 mgd (11 percent) by 2025, and approximately 2.78 mgd (17 percent) by the year 2035. 2.11 Summary of Water Use Efficiency Program The City's WUE Program provides for efficient water use and supports continued growth. This program fulfills all the necessary requirements of DOH. The selected program measures will allow the City to meet its WUE goals, resulting in decreased water demand. Measures are interrelated and will help the City achieve its goals to both reduce average water use and peak water use per customer. Public education measures (showing water use in bills, workshops, school outreach, fairs/trade shows, etc.)will continue to be a main focus of the WUE Program to increase customer awareness and knowledge of WUE opportunities. Public education is needed to support the City's other WUE measures and to support reductions in both average and peak water use. Continued appliance rebates and July 2021 —DRAFT 13 shower head give-away help customers implement what is learned in the public education campaign. With the implementation of AMI, it is expected that the City and customers will be able to identify substantially more water loss reduction opportunities than previously possible. Therefore, customer and City leak detection and water audits may have a prominent role in the 2021-2025 WUE Program. The increased water loss reduction activities are expected to support reducing average water use. The program will also continue to provide financial disincentives for excessive water use through metering and WUE pricing. This aspect of the program is likely to help reduce peak water usage further. These measures will result in the City being able to achieve its WUE goals, which results in reduced demand. In conclusion, the City will maintain the target water use efficiency goal of one percent reduction per year in the planning ERU value from 179 gpd per ERU to 172 gpd per ERU by 2025. Additionally, it is the City's goal to reduce the MDD/ADD peaking factor from 1.85 to 1.72. The goals will be reached through implementation of the proposed program measures.

A Public Water Systems, the Standard Specifications of the American Water.Works Association (AWWA), and the most recent published and adopted edition of the Uniform Plumbing Code (UPC), unless modified herein. Compliance with these standards does not alleviate the design engineer from using sound professional engineering practices. The design criteria contained herein are the minimum acceptable under standard conditions. Special conditions may require more .stringent requirements that will be addressed during the plan review process. Contact the City of Auburn Engineering Services for specific requirements for the design of pump stations, wells, reservoirs,treatment systems, and other special facilities. The design criteria used to estimate future line capacities are established in the City's Comprehensive Water Plan. Anyone proposing to extend or modify the City's water system should contact the Public Works Department for information. Applicants needing to construct public water improvements shall enter into a Developer Public Facility Extension Agreement (FAC) with the City. The City's Permit Center can provide information on this agreement as well as applicable permit and connection fee estimates. 7.01 Water Mains Unless otherwise approved by the City Engineer, all water mains shall be constructed using Special Class 52 Cement Lined Ductile Iron Pipe having standard asphaltic coating on the exterior and cement—mortar lining on the interior. The list of acceptable valves, fittings, and other appurtenances for water facility construction is subject to change as new and improved components become available. Refer to the City of Auburn's Construction Standards manual (latest edition)for the most current information on these requirements. The design of water mains shall meet the requirements in the following subsections: 7.01.01 Water Main Sizing Public water mains shall be sized using the following criteria: A. New water mains shall be sized, as indicated in the City's current Comprehensive Water Plan. For lines not specified in the plan, the mains shall be sized as described in this subsection. B. Water mains in single-family residential areas shall be a minimum of 8 inches in diameter. C. Water mains in multi-family residential and non-residential areas shall be a minimum of 12 inches in diameter. Onsite water main loops,with no possibility of future extension as determined by the City Engineer, serving two or less fire hydrants with no fire line connection may be reduced to a minimum diameter of 8 inches. D. Water mains shall be looped to provide a minimum of two separate connection points to the existing water system, with sufficient valves so that water can be Issued January 2021 City of Auburn Engineering Design Standards Page 75 delivered through either connection point independent of the other, except where determined to be not feasible by the City Engineer. Such looping will provide morereliable service and water movement through the distribution system. E. Water mains shall be sized under fire flow conditions, so that flow velocity shall not exceed 8 feet per second in distribution mains or 5 feet per second in transmission mains. F. Exceptions to the minimum diameter allowed may be made in small cul-de-sacs and in areas where looping of a main is determined to be not feasible. In these cases, the main may be a minimum of 4 inches in diameter after the last fire hydrant connection. If a conflict arises between two or more of these criteria, the water main shall be designed using the largest pipe diameter required. 7.01.02 Water Main Location A. Water mains shall be installed with no less than 42 inches and no more than 72 inches of finished cover. B. Water mains shall be located in the public right-of-way or within a public water utility easement. Water mains located in the public right-of-way shall meet the requirements of Section 9.03. C.
