The Town provides water services to approximately 11,000 people. Firestone has developed a Municipal Water Efficiency Plan update in accordance with the Water Conservation Act of 2004 and to meet the provisions of Colorado Revised Statute section 37-60-126. As part of CRS 37-60-126, a State -approved Plan will qualify Firestone for funding from the Colorado Water Conservation Board (CWCB) and the Colorado Water Resources and Power Development Authority for water supply and delivery projects. Currently, Colorado Big Thompson (CBT) water is Firestone's only water supply. Firestone's water is treated and delivered to Firestone's distribution system by Central Weld County Water District (Central Weld). After the Master meters, the Town is responsible for operating and maintaining its distribution system to its customers. In 2013, Firestone's water customers used approximately 1,799 acre-feet. The Town is expected to increase its water demand through new growth to approximately 3,052 acre-feet over the planning period which extends through 2024. Water savings from this water conservation planning effort is estimated to save 2,811 acre-feet over the planning period. The savings from this planning effort will make a considerable contribution toward the water supplies needed to serve the 2024 demand. This report documents Firestone's water system, past and future water use and the water efficiency planning process used in accordance with CWCB's Municipal Water Efficiency Plan Guidance Document. Past and Current Water Efficiency Activities Firestone has implemented a variety of water efficiency activities since 2007 when the last Water Efficiency Plan was prepared. The 2007 Plan called for savings of at least 280 acre-feet by 2015. The water efficiency activities that have been implemented since 2007 are shown in Table ES -I. The water savings from several of the Town's Targeted Technical Assistance and Incentives activities are shown in Table ES-2. The estimated water savings evident over the last five years is approximately 124 acre-feet. o 2015 Municipal Water Efficiency Plan Update Table ES-1 — Firestones Historical & Existing Water Efficiency Activities Historical and Existing Water Efficiency Activities Period of Implementation Foundational Activities Automatic Meter Reading Installation and Operations .July2014 - Present Meter Upgrades 2012 Water Efficient Rate Structure with Regular Updates to Rate Study 2009 - Present Targeted Technical Assistance and Incentives irrigation Audits for Town Parks 2011 installation of Water Efficient Irrigation Controls on Park Irrigation Systems 2012 ® Present Toilet Rebates April 1, 2010 -Present Water Efficient Washing Machine Rebates April 1, 2010 ® 2014 Give-Aways 2003 - Present Ordinances and Regulations Time of Day Watering Restriction (Voluntary) 2004 - Present Water Waste Ordinance 2007 ® Present Rain Sensors Installed On New Properties May2003 - Present Wind Sensors installed On New Properties Greater than 9 Acre May2003 - Present Education Activities Water Efficiency Page on Town Website Prior to 2007 -Present Historic Water Usage Provided on Water Bills Bill Stuffers Newsletter K-12 Teacher and Classroom Education Programs Water Booth at Town Events Social Networking (e.g. Faceb ook) Customer Surveys Table ES-2 —Water Savings Estimates of Individual Activities Historical and Current Water Efficiency Activities of Firestone Annual Water Savings for Past Five Years {ac-ft) ; Total Fve Year Water SaAn s Average', Annual Savin s 2009 2010 "2011 i 2012 2013 Targeted Technical Assistance and Incentives Irrigation Audits for Town Parks n/a n/a n/a 0 112 112 56 installation of Water Efficient Irrigation Controls on Park Irrigation Systems Toilet Reb ates n/a 0.2 0.6 0.9 1.1 3 0.7 Water Efficient Washing Machine Rebates n/a 1.1 2.1 2.9 3A 10 2.4 Total Savings 1' 3 4 117 124 69Town 2015 Municipal Water Efficiency Plan Update The water savings for the remaining activities shown in Table ES-2, who's saving were not analyzed above, are more difficult to quantify. Therefore we estimated the water savings of the remaining activities using demand data to compare historical annual per capita water demands before and after the implementation of the water efficiency activities. Figure ES=1 shows the annual historical per capita water demands in relation to population and when water efficiency activities were implemented. Figure ES®1 suggests a decreasing trend in gallons per capita per day (GPCD) despite a significant increase in population. We conclude that the water efficiency activities enacted since at least 2007 have contributed to the reduction of per capita demands. Because a majority of the water efficiency activities were more recently implemented, more time is needed to analyze the impact of these implemented activities. An increase in the 2012 GPCD may be due to the drought that started in 2012 and ended with the flooding in 2013.

A meeting was initially held with Town staff to discuss water efficiency goals appropriate for Firestone. The following preliminary goals were established by Town Staff: ® In keeping with the savings goal established in Firestone's 2007 Water Efficiency Plan, the targeted water savings goal for this Plan will be to lower the total water use by 12% over the planning period. ® The targeted planning period water savings goal for the following customer categories are as follows: o Residential — 15% o Multi -Family — 2.5% o Commercial — 5.0% o Industrial — 2.5% o Parks — 10% o Open Space — 10% o Non -Revenue — 6.0% (of total treated water demand) ® Develop a water efficiency program that can be implemented within Town staffing constraints and with Staff approval. ® Implement water efficiency activities that are compatible with the community and their Town Board representatives. Firestone used afour-phase process for selecting and fully evaluating water efficiency activities. The four phases include: 1) assessment; 2) identification; 3) qualitative screening; and 4) evaluation and selection. The initial screening of the water efficiency activities with Town staff resulted in selecting 15 candidate activities for further evaluation. The second screening was accomplished by evaluating each activity based on the following evaluation criteria: • Practical from acost/benefit standpoint ® Implementation costs are feasible from a financial and staff resource perspective ® Candidate activities collectively meet the targeted savings goals All 15 evaluated activities were chosen for implementation. The activities selected are as follows: • Automatic Meter Reading Installation and Operations ® Proactive Meter Testing and Replacement ® Water Efficiency Rate Structure with Regular Updates to Rate Study ® System Wide Water Audits ® Installation of Water Efficient Irrigation Controls on Park Irrigation Systems ® Installation of Water Efficient Irrigation Controls on HOA Irrigation Systems ® Toilet Rebates ® Give-Aways ©Clear Water solutions, Inc. 2015 Municipal Water Efficiency Plan Update sown of Firestone ES-4 ® Rain Sensors Installed on New Properties ® Wind Sensors Installed on New Properties Greater than One Acre ® Water Efficiency Page on Town Website ® Bill Stuffers ® Historic Water Usage Provided on Water Bills ® Newsletter ® K-12 Teacher and Classroom Education Programs Table ES-3 compares the anticipated water savings from the selected activities with the original goals and then adjusts the water saving goals for this plan update.

Over the planning period, the selected activities provide an overall estimated water savings of 2,811 acre-feet. Preliminary goals were adjusted down for the Residential, Commercial and Industrial categories. The MultkFamily, Parks, Open Space and Non - Revenue Water category goals were adjusted up to match the estimated water savings resulting from the cost -benefit analysis. The adjusted goals reflect the goals believed to be obtainable by Town staff. After the goals were adjusted to reflect the expected water savings, the estimated water use reduction is 10%. Therefore, Firestone will target a reduction in its water use by 10% over the planning period because of implementation of this plan. 2015 Municipal Water Efficiency Plan Update Implementation and Monitoring Plan All of the proposed water efficiency activities chosen will require staff and financial resources for implementation. This will require some strategy in implementing the most beneficial measures first. The proposed implementation schedule is shown in Table ES=4.

Ms. Pasillas maintains water use data and evaluates water demands on a regular basis. Ms. Pasillas will monitor this Plan's implementation and evaluate impacts on a regular basis. o 2015 Municipal Water Efficiency Plan Update filklz�� LK&N1 The Town of Firestone is located approximately 30 miles north of Denver along the Colorado Front Range as shown in Figure 1.1 below. The Town's population in 2000 was 1,980 and exploded to 10,147 people in 2010. The Town has experienced a steady growth rate since 2010 and as of 2014 the population was estimated to be 10,962, Currently, Colorado Big Thompson (CBT) water is Firestone's only water supply and the Town is looking to conserve this resource for its constituents as much as reasonably possible. CBT water originates in the Colorado River Basin and is pumped from Lake Granby through the Adam's Tunnel to the east slope near Estes Park. Water from Estes Park.is distributed to several Front Range reservoirs. Firestone's water is treated and delivered to Firestone's distribution system by Central Weld County Water District (Central Weld). Firestone entered a new twenty-year agreement for Central Weld in 2014 with automatic ten-year renewals. Central Weld has a water treatment plant at Carter Lake where it treats Firestone's water and delivers it to master meters located at various points surrounding the Town's limits. After the master meters, the Town is responsible for operating and maintaining its distribution system to its customers. Firestone owns the CBT water it uses and transfers its CBT water to Central Weld on an annual basis for Central Weld to treat and deliver up to the master meters. The Town of Firestone is currently required to transfer water rights equal to 120% of the Town's water usage in the previous year plus additional water to meet anticipated growth in the coming year. The Town currently has a Rate Study completed in 2011, a Rate Study update completed in 2014, a Drought Management Plan completed in 2012, and the initial Municipal Water Efficiency Plan (MWEP) completed in 2007. These documents were reviewed in the development of this MWEP update. The Town believes this updated MWEP will serve to further conserve and manage their limited water resources and evaluate the effectiveness of conservation efforts made since the initial MWEP. In this Plan update, the Town of Firestone will perform the five steps of municipal water efficiency planning as outlined in the Municipal Water Efficiency Plan Guidance Document; 1) profile of existing water supply system, 2) profile of water demands and historical demand management, 3) integrated planning and water efficiency benefits and goals, 4) selection of water efficiency activities, and 5) implementation and monitoring plan. The Town has made many proactive conservation efforts to date and will continue this commitment into the future. r { Hk �4 1E 11 s' -. t r A I -i — _ - 1 s� _��.- -,e RiverIt It to - , t ¢ • Putt _ C It s- to :rt It I Minimal mullpt 1� � r / t+ i �E— l,� Li — a' _ ��s LI 214 � it s I �1 w r =� P , �. y r�. cV '>?` T 1 d"to top i� �3 , —t i j`< too,''�1 e itoklamw tt r. + a t � � - -- �it }9 - — 1 LO J..

The Town Board of Firestone is committed to water resource sustainability and water efficiency. The Town intends to do its part to preserve water for future generations. Both Staff and the Board understand the needs and benefits to implement long-term water efficiency activities. �f, POI.. w r: 1.1 Overview of Existing Water Supply System Service Area The Town's service area is generally located east of Interstate 25 between Highway 119 and Highway 52 and includes an area of 17 square miles as shown on Figure 1.1. The planning area for the Town encompasses 26 square miles. Water Supply Firestone currently does not operate a water treatment plant and is a wholesale purchaser of potable water. Firestone does not have a dual water supply system. The Town's water supply consists solely of CBT units of which the Town owns 5,095 units. The Town of Firestone transfers the CBT water it owns to Central Weld on an annual basis for Central Weld to treat and deliver up to the master meters. Firestone is currently required to transfer water rights equal to 120% of the Town's water usage in the previous year plus an additional 10% to meet anticipated growth in the coming year. This 20% safety factor is built in to account for system operations (i.e. backwashing of filters and minor system losses) and to ensure Central Weld can meet the water needs of the Town for the upcoming year. The forecasted demands in this report are for Firestone customer use only and do not reflect the additional 20% required by Central Weld, The CBT system contains transbasin water that accumulates in the Colorado River Basin and is pumped [Will Lake Granby through the Adam's Tunnel to the east slope near Estes Park. Water is then distributed to several Front Range reservoirs. It was constructed by the Bureau of Reclamation between 1938 and 1957 and is maintained by the Northern Colorado Water Conservancy District (Northern Water). Key Existing Facilities Central Weld treats water at the Carter Lake Filter Plant, outside of Berthoud. Once treated, Central Weld delivers the water to the Town through their own distribution network consisting of a 25-mile pipeline delivery system. Additional CBT water is conveyed to the Town by developers as new development occurs. Firestone has ten points of connection to Central Weld's system, each consisting of a master meter vault and appurtenances. Central Weld has storage throughout its system, including 12 million gallons (MG) southeast of Town, to provide a reliable supply to its constituents. Firestone constructed a 1.5-MG storage tank at this location. This 1.5-MG tank helps to meet peak -hour demands and to stabilize pressure throughout the Town's distribution system. Every service connection on the Town's distribution system, regardless of use, is metered. All of the system meters are read monthly, and the Town is confident in the design of the system to account for all water use — including hydrant meters used by contractors that buy construction water from the Town. The water use monitoring program the Town has been using for the past twelve years has been an integral part of Public Works' efforts to minimize system leakage. 1.2 Water Supply Reliability The Town of Firestone is located in the South Platte River Basin where the Statewide Water Supply Initiative (SWSI) 2010 identified a 58% gap between water needs and water supplies in the Basin by 2050. Water efficiency is one method the SWSI report identified for meeting this gap. Water supply reliability is the ability of the Town's water supplies to meet the needs of its customers during times of stress. The CBT Project imports an average of 213,000 acre-feet of water each year to many public and private water users along the northern Front Range and northeastern Colorado for agricultural, municipal and industrial uses. The system has approximately 740,000 acre-feet of gross storage and consists of 310,000 units. There is approximately 2.3 times the storage than would be needed to deliver a 100% quota. This gives the CBT system some drought reliability. In over fifty years of CBT project operation, the average yield has been 0.73 acre-feet per unit and the commonly used average quota is 70%. The yield has never been less than 0.50 acre-feet per unit (50% quota) or more than 1.0 acre-feet per unit (100% quota). The historical annual quota established by the Northern Water Board is shown on the following Figure 1.1. Northern Water defines a CBT carryover program to CBT Allottees, which allows CBT owners to carry over unused CBT from the previous year to the following year. Per Northern Water's Annual Carryover Program Procedures: The Board and District staff will review the advantages and consequences of the Annual Carryover Program on a continuing basis. While the Board recognizes the Program's benefit to many CBT Allottees, it may modify or discontinue the Annual Carryover Program at any time. Considering this procedure, a 50% quota is what most water provider's use as the firm yield for CBT. Since the Town only owns CBT units at this point, calculating the firm yield is relatively simple. Figure I. I — Historical CBT Quota Table 1.1 — Firestone's Current Water Supply Firm Yield Noi of Units Uni# Firm Yield (ac-ftper unit) i Total Firrn Yield ac-ft 51095 0.5 2,547.50 Other Factors that Potentially Impact Water Supply The CBT supplies are stored in Lake Granby on the western slope of Colorado. Should a fire ever occur in the area, water quality would be a major issue for Firestone and other CBT Allottees. There is a tremendous amount of beetle kill to trees surrounding Lake Granby. This beetle kill poses an increased risk to fire. Firestone would be vulnerable to Central Weld's abilities to treat degraded water quality and east slope CBT storage, once segregated from the system to avoid contamination, is not enough storage to meet demands — particularly in a drought. Firestone's water supplies would also be vulnerable in an extended drought. The Town currently maximizes its carryover each year through Northern Water, but amulti-year drought would likely decrease or eliminate Firestone's carryover account. Typically, the Town leases out all of its excess water supplies. Firestone retained this excess in 2003 (after the 2002 drought), and it served as an adequate "cushion" to see how the 2003 year would play out. In the latter part of 2003, the Town was able to lease excess water out to other municipalities that needed it. 1.3 Supply -Side Limitations and Future Needs Limitations with CBT Current CBT supplies are sufficient to meet Firestone's water demands. To date, there have not been any potable supply shortages. However, it should be noted that the CBT system was originally designed as a supplemental supply to native water rights. Each year, the amount of water delivered by the CBT system (i.e. quota) was set based on demand. For example, in a dry year when water demands are highest, the quota would be set higher (i.e. 100%). Conversely, in a wet year, when native supplies are plentiful, the quota would be set lower (i.e. 50%). The years 2002 and 2003 were an exception when, for the first time in the system's history, the quota was set based on the limited supply in the CBT system. To maintain this delicate balance, and to prevent speculative water purchases, Northern Water has set limits on the amount of CBT water each entity can own in relation to its water demand. Since Firestone owns sufficient CBT to meet its demand, it has exceeded its CBT ownership as compared to the demand associated with its committed taps per Northern Water regulations. Because of this fact, the Town is "capped" and cannot purchase additional CBT supplies through the open market. Accordingly, the Town must rely on additional CBT acquisition through dedication from developers annexing into the Town. This Northern Water requirement puts a burden on the Town to figure out other sources of domestic supply since it cannot purchase additional CBT water. A key limitation with CBT water is the fact that it is in great demand and is converting fI om agricultural use to municipandustrial use, rapidly. Currently, the oil and gas industry it taking a significant amount of CBT water when it goes to the open market. Limitations with Central Weld Central Weld being the sole water provider to the Town limits the Town's options for water acquisition to meet future growth. Only CBT water can be acquired and transferred to Central Weld for treatment, unless Firestone chooses to construct its own water treatment facility. In addition, there are portions of the Town where low water pressure is a problem. There are many portions of Central Weld's system near the Town that currently are not looped, so delivery of water at adequate pressures to key locations within the Town is a concern. Town System Limitations The Town of Firestone owns and operates a water distribution network of approximately 58.5 miles of pipeline and associated facilities. Over 95% of this network was installed after 1995 and was subject to design and installation in strict accordance with the Town's published criteria and standards and is in excellent operating condition. The remaining portion of the network is located in the historic "old town" area and was installed in the early 1970's. This older portion of the network is primarily 4", 6", and 8" diameter asbestos cement pipe. The integrity of the older pipe is adequate but system capacity evaluations have shown that over time this portion of the network needs to be replaced with larger capacity pipe to improve delivery, especially for fire suppression flows. The Town is scheduled to start replacing the water pipelines in the Old Town area in 2015. The Town is currently operating five separate water distribution systems. Depending on location, if one part of the system goes down, i.e. repair, leak, etc., it could be difficult to deliver water at adequate pressures and volumes to other sections of Town. To solve this concern, the Town intends to loop these five systems together in the future. By looping the entire system together, the 1.5-MG tank can be effectively used to serve all portions of Town as needed. Future Needs The Town recognized the need to further develop their water supplies and is in the process of trying to acquire some Windy Gap shares. This need became evident for the Town after the 2002 drought impacts, and more recently after the drought of 2012-2013. Firefighting capabilities for the Town suffered moderately during the droughts and an increased water supply and storage would help the Town sustain this service leading into the next drought. Planning Initiatives The Town of Firestone completed a Water Infrastructure Master Plan in 2003. This plan focused on infrastructure and system capacity needs to meet future growth and identified capital improvement projects within the Town. The Town has recently completed a Water Rate Study update, which will help assess if there is a need to increase rates to continue to meet projected water needs and adequately serve the community. The Town is currently completing a Water Resources Master Plan. This plan will address water demands associated with growth, evaluate current water supplies, identify new water supplies, determine which supplies the Town should acquire, and develop a plan to achieve the desired water portfolio. Due to the rapid growth the Town is experiencing, Firestone realizes the importance to complete a Water Resources Master Plan that will identify its water and storage needs and guide the Town intelligently into the future. 0 2.1 Demographics and Key Characteristics %J the Service Area The Town of Firestone provides water and wastewater services to approximately 10,962 residents. The Town is projected to grow at an increased rate as the economic recovery effort in the area continues from the recent recession. The Town's billing system uses the following customer category assignments for its water service accounts: • Residential - Firestone's Residential category includes all single-family residences from low to high density and mobile homes, but does not include Multi -Family units like apartment complexes, and assisted living facilities. • Multi -Family - Firestone's Title 17, Zoning Codes (17.08.110) describe Multi -Family as "a building designed to be occupied in whole or in part by three or more families living independently of each other, but not including mobile homes or manufactured homes..." • Commercial - The Commercial category contains businesses, retail stores, and community organizations like churches and school districts. The Commercial category represents the third largest water user category in Firestone. • Industrial - Currently, there are two customers that make up the Industrial customer category. The Industrial category is one of the smallest water user categories in Firestone. • Parks - The Parks customer category is water demand associated with turf areas owned and maintained by the Town. These include parks and irrigated areas around government buildings. • Open Space - The Open Space customer category is water demand associated with irrigated areas owned and managed by independent entities, such as private home owner associations and not by the Town. 2.2 Historical Water Demands Annual Treated Water Central Weld delivers treated water to Firestone's master meters located at various points surrounding the Town limits. After the master meters, the Town is responsible for operating and maintaining its distribution system to its customers. Table 2.1 shows the annual treated water deliveries made by Central Weld for the last five years. Table l l —Central Weld Annual Treated Water Delivery Annual Treated Water Use by Customer Category The overwhelming majority of the Town's treated water goes to Residential water users. However, a significant portion also goes to Parks and Open Space categories. At this time, there are not many large water users in the commercial and industrial sectors. The Town's average water demand for 2006 through 2013 for each customer category is shown on Table 2.2. The total water usage has ranged from 1,668 to 2,235 acre-feet and averages 1,877 acre-feet. Also shown in Table 2.2 is the total and Residential category per capita water use, expressed as gallons per capita per day (GPCD). The GPCD is calculated as the total water use or Residential (and MultkFamily) water use divided by the population.

Figure 2.1 indicates an increase in GPDC in 2012 which may be due to the 2012 drought that lasted into early 2013. Figure I I — Firestone Total Water Use Per Capita Figure 2.2 breaks out the water usage per customer category as a percentage of the total use for 2011 It shows the Residential category is the largest at approximately I.3% of total usage. Figure 2.2 — 2013 Treated Water Use The indoor and outdoor use was estimated using the total usage per month for the last five years of data 2009-2013. The total monthly water use between November and February was assumed to be only associated with indoor use. This total divided by the number of days between November and February was calculated as the average indoor use per day. The indoor use for the other months of the year, March through October, was calculated as the average indoor use per day multiplied by the days per month. The outdoor monthly use was assumed to be the difference between the total monthly use and the indoor monthly use. Figure 2.3 is a chart breaking -out the estimated average monthly indoor and outdoor water use. Figure 2.3 —Average Monthly Indoor &Outdoor Water Use Annual non -revenue water, or unaccounted for water, consists of unbilled authorized uses (e.g. hydrant flushing), apparent losses, and real losses. Apparent losses consist of unauthorized consumption, customer metering inaccuracies, and data handling errors. Real losses consist of leaks in the water distribution system that does not reach the end user. To estimate Firestone's non -revenue treated water we examined the difference in the annual treated water delivery from Central Weld and what was metered at the water taps throughout the Town between 2009 and 2013. The data shows the non -revenue treated water for Firestone is less than 10% (6% in 2013), which is considered good by industry standards. 2.3 Past and Current Water Efficiency Actives and Impact to Demands Firestone has implemented a variety of water efficiency activities since 2007 when the last water efficiency plan was prepared. The 2007 Plan called for savings of at least 280 acre- feet by 2015. The water efficiency activities that have been implemented since 2007 are shown in Table 2.3.

The estimated water savings evident over the last five years is approximately 124 acre-feet.

The intent of the irrigation site assessment was to obtain details regarding operation of the irrigation system, controller programming, general soil conditions, and discussion with maintenance staff to provide helpful insights of the irrigation system. Representative zones were audited to evaluate irrigation system performance and to gain an understanding of water efficiency opportunities. Among the many recommendations made in the irrigation audit was the recommendation to replace existing Hunter ICC controller with a centrally controlled, weather based controller. By 2013 the Town had begun replacing the old irrigation controllers with Rain Master iCentral Controlled Irrigation Systems. By the end of 2013, ten controllers had been replaced. Some of the features included with the iCentral System include: • Local weather information is automatically sent to each controller every day • Smart AlertsT"' are sent by iCentral for all field alarms generated when a "fault" occurs; text messages are sent to cell phone and email address • Automatic initiation of "rain shutdown" to each controller if iCentral determines that precipitation in a designated area necessitates a shutdown. • Automatically modifies irrigation schedules based upon daily ET, as well as plant watering requirements • Manually turn on/off any station or program Firestone staff estimated that the 2013 usage for the Parks with the new controllers decreased by 37% when compared to 2012. A total of 5.27 inches of precipitation was received in Firestone prior to the September 2013 rain storm that brought an additional 8.44 inches. 2013 was on track to be dryer than 2012, which makes the amount of water saved in 2013 very remarkable. 36,617,000 gallons of water was saved compared to 2012, which equates to 112.37 acre-feet of water. Toilet and Washing Machine Rebate Activities The Town began the Toilet and Washing Machine Rebate activities in August 2010 thanks to a Water Efficiency Grant provided by the Colorado Water Conservation Board (CWCB). As of December 31, 2014 the Town had issued approximately 245 washing machine rebates and 42 toilet rebates. In 2014, through September, the Town issued five washing machine rebates and one toilet rebate. Overall, the Town has had a slow and steady response for these rebates. The Toilet Rebate program offers a $75.00 rebate for the installation of qualifying high - efficiency toilets purchased after April 1, 2010. Qualifying toilets are low flush (1.28 gallons/flush or less) and dual flush toilets. The Washing Machine Rebate program offered a $125.00 rebate for the installation of qualifying high -efficiency clothes washers purchased after April 1, 2010. Qualifying washers were listed on the Town's website. For the water savings analysis, we considered the usage of the participants for the core winter months of November through February as all indoor use. The 2014 data did not include any usage for the core winter months and therefore was not analyzed in our study. Some of the participants applied for both the toilet and washing machine rebate program. Data from these participants was eliminated from our analysis because it was too difficult to determine which rebate program to associate the savings to. Data from participants was also eliminated if there was insufficient usage before or after the rebate was issued. This was often the case for the following reasons: • The rebate was issued in early 2009. ® The rebate was issued in late 2013. ® The rebate was issued for new construction. ® The residence changed ownership during the study period and was vacant for part of the time. Our analysis showed that the toilet rebate program has shown a higher water savings per participant than the washing machine program. For the Toilet Rebate program, after filtering the data as discussed above, we ended up with twelve participants that were analyzed. This rebate program showed an average savings of approximately 18.7%. The indoor average usage of each participant before the rebate was issued was 4,151 gallons per month (based on the core winter months) and after the rebate was issued it was 3,452 gallons per month. This equates to a savings of approximately 699 gallons per month, or 0.026 acre-feet per year per participant. The Town is planning on continuing the toilet rebate program. The Washing Machine Rebate program had more participants, and therefore had a higher overall water savings associated with it. However, the water saving per participant was less with the Washing Machine Rebates. There were a total of 250 participants for this program and we looked at the data for 100 participants. After filtering the data, we had 96 participants that were analyzed. This rebate program showed an average savings of approximately 8.6%. The average indoor usage of each participant before the rebate was issued was 4,825 gallons per month and after the rebate was issued it was 4,436 gallons per month. This equates to a savings of approximately 389 gallons per month, or 0.014 acre-feet per year per participant. We spoke to the Town staff about the lackluster saving per participant evident for the washing machine program versus the toilet program and they felt many washing machine rebates went to new construction and were not being used to replace less efficient washing machines. Another adverse aspect of the washing machine rebate is that the water efficient washing machines are not a permanent fixture in the home and so if residents moved they often take the washing machines, and water savings, with them. Water Savings Estimates Using Demand Data The water savings for the remaining activities shown in Table 2.3, who's saving were not analyzed above, are more difficult to quantify. Therefore we estimated the water savings of the remaining activities using demand data to compare historical annual per capita water demands before and after the implementation of the water efficiency activities. Figure 2.4 shows the annual historical per capita water demands in relation to population and when water efficiency activities were implemented. Figure ')Asuggests a decreasing trend in GPCD despite a significant increase in population. We conclude that the water efficiency activities enacted since at least 2007 have contributed to the reduction of per capita demands. Because a majority of the water efficiency activities were more recently implemented, more time is needed to analyze the impact of these implemented activities. An increase in the 2012 GPCD may be due to the drought that started in 2012 and ended with the flooding in 2013.

This forecast shows demand starting in 2014 and going through the planning horizon of 2024 (11 years). The baseline forecast is based on a combination of anticipated demographic and land use changes in Firestone. In the baseline forecast, demands increase proportionally with the population at the current rate of usage. Population is expected to grow from the 2013 level of 10,699 people to 17,015 people in 2024. The population forecast is shown in Table 2.5. The baseline water demand forecast is shown in Table 2.6.

Under the revised forecast, it is estimated that total demands for Firestone in 2024 will be about 830 acre-feet greater than they are in 2014. Firestone plans to accomplish this level of water efficiency by focusing on water efficiency for large irrigated areas.

The benefits of this planning effort may include: - • Freeing up water supplies for increased growth and development • Additional water to cover shortages during droughts or other emergency situations • Delaying the purchase of additional water supplies 3.3 Water Efficiency Goals Water efficiency goals are intended to lay out a set of targeted objectives that if accomplished, will result in the identified benefits. A preliminary set of goals have been developed prior to the selection of the water efficiency activities to provide a means to screen and evaluate the selected activities. Goals from the Town's 2007 Municipal Water Efficiency Plan have been assessed and incorporated into the new goal development process. A meeting was initially held with Town staff to discuss water efficiency goals appropriate for Firestone. The following preliminary goals were established by Town Staff: • In keeping with the savings goal established in Firestone's 2007 Water Efficiency Plan, the targeted water savings goal for this Plan will be to lower the total water use by 12% over the ten-year planning period. • The targeted ten-year water savings goal for the following customer categories are as follows: o Residential — 15% o Multi -Family — 2.59/o o Commercial — 5.0% o Industrial — 2.5% o Parks — 10% o Open Space — 10% o Non -Revenue — 6.0% (of total treated water demand) • Develop a water efficiency program that can be implemented within Town staffing constraints and with Staff approval. • Implement water efficiency activities that are compatible with the community and their Town Board representatives. The success of the stated goals will be measured through monitoring of billing data, screening and evaluating activities that are acceptable to Town Staff and soliciting Town Board and community feedback on water efficiency activities. 4.1 Summary of Selection Process Firestone used afour-phase process for selecting and fully evaluating water efficiency activities. The four phases include: 1) assessment; 2) identification; 3) qualitative screening; and 4) evaluation and selection. Assessment, Identification and Qualitative Screening Using the analysis performed and presented in Section 2.3, the Town identified areas where water efficiency could be enhanced. With the water saving success of the installation of water efficiency irrigation controls on park irrigation systems, the Town would like to continue this activity for other parks as well as expand to open space areas. In addition to these irrigation control activities, the Town generally wants to focus on activities that assist with meeting their water efficiency goals. We utilized Worksheets D-G from the Municipal Water Efficiency Plan Guidance Document to identify a list of water efficiency activities that are generally compatible with the Town's needs. A copy of Worksheets D-G can be found in Appendix B of this report. The list of activities evaluated are organized according to the SWSI Levels Framework. The SWSI Levels Framework was developed as a component of the 2010 SWSI update to organize water efficiency activities into a model that assists municipalities in prioritizing and selecting activities. The framework may be represented as a cylinder consisting of the following four categories in Figure 4.1.E SWSI Levels Framework includes the following levels of water efficiency activities: ® Foundational Activities —Focus on system operations and water efficiencies that are under Firestone's direct control and can improve the effectiveness of the planning effort by ensuring sufficient metering and data tracking. ® Targeted Technical Assistance and Incentives — Covers activities that water providers and customers can do to improve existing water efficiency. These categories were initially introduced the 2010 SWSI Conservation Level Analysis Final Report as a component of CWCB's water conservation technical platform. Note: The SWSI Levels Framework terminology has been updated since this report. Figure 4.1 — SWSI Levels Framework Targeted Technical Assistance and Incentives 11 Education Activities ordinances and Regulations • Ordinances and Regulations —Includes regulatory activities designed to encourage water efficiency. • Education Activities — Educate the public on the benefits of water efficiency, inform customers on how they can reduce their water usage and publicize water efficiency activities that Firestone is implementing. Further discussion regarding the SWSI Levels Framework is provided in subsequent sections. Town staff developed qualitative screening criteria used to screen the preliminary list of activities. The screening criteria include: 1) beneficial in water savings; 2) Staff availability and approval; 3) Town Board and public approval. Activities not meeting the screening criteria were eliminated. The specific reason for elimination of activities can be found in Worksheets D-G, located in Appendix B. Evaluation and Selection The evaluation and selection phase of the selection process involves development of evaluation criteria, evaluation of the activities, and selection of the final activities for implementation. The evaluation criteria include: ® Practical from a cosubenefit standpoint ® Implementation costs are feasible from a financial and staff resource perspective ® Candidate activities collectively meet the targeted savings specified in Section 3.3 4.2 Evaluation of Candidate Activities The initial screening of the water efficiency activities with Town staff resulted in selecting 15 candidate activities for further evaluation. Eliminated activities will be evaluated with future planning efforts. Some of the activities have been combined within their SWSI Levels Framework to assist in evaluation and avoid double counting savings. The water savings and costs of the selected activities are shown in Table 4.1. Details about the cost -benefit evaluation and information about each measure can be found in the following section with further detail available in Appendix C. Foundational Activities ® Automatic Meter Reading Installation and Operations —This is an existing activity that was implemented in 2012. Town of Firestone installed a new meter reading system that allows water meters to be read hourly down to a single gallon of water. The system allows water customers to view and manage their water usage through AquaHawk, which is secure website where customers can set up alerts for notification on possible water leaks, irrigation usage issues, promote water conservation, set monthly water usage budgets and receive alerts if a set budget is going to be exceeded. Signing up to manage water usage through AquaHawk is completely voluntary. To date, only a small percentage of Firestone residents have signed up. Staff hopes to have more water users participate over the planning horizon. ® Proactive Meter Testing and Replacement — For this activity, existing meters will be tested periodically for leaks and accuracy and are replaced as necessary. Because meters were recently replaced (2012), we do not anticipate a significant annual water savings during this efficiency plan period. ® Water Efficiency Rate Structure with Regular Updates to Rate Study — The Town conducted their first water rate study in 2008 thanks to a grant provided by CWCB. The Town conducts a rate study update every three years. The rate study helps to ensure maximum water conservation savings. ® System Wide Water Audits — This activity would include leak detection and repair for Town water delivery infrastructure. A leak survey would be performed by a consultant.

The Town would like to install these meters at all parks and estimate that approximately 31.5 acres of irrigated parks are left to be converted. Please refer to Section 2.3 of this report for further details on the controllers. • Installation of Water Efficient Irrigation Controls on HOA Irrigation Systems — The Town of Firestone is proposing to work with Open Space customers to install Irrigation System Efficiency Devices or ET irrigation system controllers on the Open Space irrigated areas. The Town proposes to assist their Open Space customers by covering the cost of the Rain Master iCentral controller. • Toilet Rebates — The Town desires to continue their existing Toilet Rebate program. Please refer to Section 2.3 for further details on this activity. • Give-Aways — This is an existing activity. The Town gives away faucet aerators and low -flow shower heads at Town events for the public. Ordinances and Regulations • Rain Sensors Installed on New Properties —This regulation was first initiated in 2003 and develops standards that requires rain sensors for new developments. The Rain Sensor regulation applies to all customer categories except Parks and Industrial. • Wind Sensors Installed on New Properties Greater than One Acre — This regulation was also first introduced in 2003. This regulation requires wind sensors for new properties irrigating more than 1-acre. Educational Activities • Water Efficiency Page on Town Website, Bill Stuffers, Historic Water Usage Provided on Water Bills, Newsletter, K-12 Teacher and Classroom Education Programs, Water Booth at Town Events, Social Networking and Customer Surveys — For evaluating the benefits and costs we combined all of the Town's educational activities. The Town provides educational activities for grade school children that focus on the Town's water supply and teaches water efficiency. Water efficiency questions are included in an annual customer survey. Comparison of Benefits and Costs As shown in Table 4.1, the cost for the evaluated activities varied from $0.00 per 1,000 gallons for water efficiency rate structures with regular updates to the rate study to $5.58 per 1,000 gallons for installation of water efficient irrigation controls on Open Space irrigation systems. 4.3 Selection of Activities for Implementation The second screening was accomplished by evaluating each activity based on the evaluation criteria discussed in Section 4.1. All 15 evaluated activities were chosen for implementation. In Section 3, water efficiency goals were established for the customer categories: o Residential — 15% o MultkFamily — 2.5% o Commercial — 5.0% o Industrial — 2.5% o Parks — 10% o Open Space —10% o Non -Revenue Water — 6.0% (of total treated water demand) The selected water efficiency activities and associated water savings were arranged within the targeted customer categories to more easily compare the anticipated savings to the original goals. Some of the measures contribute savings to more than one category. Table 4.2 shows the water savings for the selected activities, sub -totaled for each category. These savings were compared to the original goals set in Section 3. Table 4.3 compares the anticipated water savings from the selected activities with the original goals and then adjusts the water saving goals for this plan. Over the planning period, the selected activities provide an overall estimated water savings of 2,811 acre-feet. Preliminary goals were adjusted down for the Residential, Commercial and Industrial categories. The MultkFamily, Parks, Open Space and Non - Revenue Water category goals were adjusted up to match the estimated water savings resulting from the cost -benefit analysis. The adjusted goals reflect the goals believed to be obtainable by Town staff. After the goals were adjusted to reflect the expected water savings, the estimated water use reduction is 10%. Therefore, Firestone will target a reduction in its water use by 10% over the planning period because of implementation of this plan.

Julie Pasillas, Senior Administrative Specialist, is chiefly responsible for implementation of this Plan. Ms. Pasillas has been successfully implementing the Town 's water efficiency program since 2007. The Town will continue to work to budget money and pursue CWCB water efficiency grants to meet its water efficiency goals. Firestone has developed a phased implementation approach to the efficiency. The proposed implementation schedule is shown in Table 5.1.

Ms. Pasillas maintains water use data and evaluates water demands on a regular basis. Ms. Pasillas will monitor this Nan's implementation and evaluate impacts on a regular basis. A summary of the data to be collected for Water Efficiency Plan monitoring is presented in Table 5.2 which is based on Worksheet K from the Guidance Document. Every year on a regular and on -going basis, the Town inputs new supply and demand data into the CWCB Water Efficiency Data Portal, to project water supplies under the most recent hydrologic, growth, and demand scenarios.

Since Firestone has had a municipal water efficiency program in place since-2007, the public has become familiar with the efficiency concept and activities. The Town's public education program has contributed to this level of awareness. For this water efficiency planning process, the public was notified of the 60-day comment period from February 20, 2015 to April 21, 2015 and how to submit comments. The pIan was made available on Firestone Is website and at Town Hall for review. A total of four public comments were received during the 60 day comment period. To the extent possible, comments were addressed in the revised water efficiency pIan update. Copies of public notice announcements, all public comments, and the official plan adoption resolution are provided in Appendix D. 6.2 Local Adoption and State Approval Process The Town of Firestone Water Efficiency Plan Update was submitted to the CWCB Office of Water Conservation and Drought Planning on May 13, 2015. On July XX, 2015 the Town received official notification that the plan was approved by the CWCB. 6.3 Periodic Review and Update The City plans to review and update this conservation plan every seven years. The next update is scheduled to be completed in 2022. m Acre-foot (ac4q: The amount of water it would take to cover one acre of land to a depth of one foot; approximately 325,851 gallons. CBT: Colorado Big Thompson CBT Quota: The percentage set by the NCWCD Board of Directors each water year which determines the amount of ac-ft per unit of CBT, i.e. 70% quota equals 0.7 ac-ft per CBT unit. Central Weld (CWCWD): Central Weld County Water District Demand Management: The implementation of water efficiency activities to reduce water deliveries (demands) and or improve efficiencies within the distribution system. For purposes of this document, demand management refers to both system and customer water demands. Demand management is used interchangeably with water efficiency. Demand -side: The distribution and consumption of treated water supplies for domestic purposes or the delivery and use of reclaimed water or untreated raw (i.e. ditch water, groundwater) for non -potable purposes such as irrigation or industrial processes. Dual Water Supply Systems: Water supply systems that use a combination of treated water to meet potable water needs and reclaimed water and/or non -treated water (i.e. untreated ditch water and groundwater) to meet non - potable water needs. ET Controllers: Evapotranspiration controllers adjust the amount of water applied from sprinkler systems based on soil moisture and weather conditions. GPCD: Gallons per Capita per Day gpd: Gallons per day MWEP: Municipal Water Efficiency Plan N/SP: Northern Integrated Supply Project Non -Potable Use: Water that is not treated and used for irrigation or other uses than potable. The District currently does not have a non -potable water supply. Non -Revenue Water: Annual non -revenue water (previously referred to as unaccounted for water) consists of unbilled authorized uses (i.e. hydrant flushing), apparent losses, and real losses1. Real losses consist of leaks in the water distribution system that does not reach the end user. Apparent losses consist of unauthorized consumption, customer metering inaccuracies, and data handling errors. Northern Water: Northern Colorado Water Conservancy District Phreatophytes: Species of plants and trees that consume groundwater through their root zones below the water table such as Cottonwood and Russian olive trees. Potable Use: Water that is treated to drinking water standards for municipal use, including residential and commercial use. Supply -Side: Water supply operations and facilities that include the diversion, extraction, storage, and transmission of untreated water. System Water Demand: Volume of water necessary to meet customer water needs within a certain period of time. System water demand is typically measured at the point of discharge from the water treatment plant and includes non -revenue water. In dual water supply systems, system water demand may also include the distribution and delivery of non -potable water (i.e.: reclaimed water and untreated ditch and groundwater) to meet irrigation needs. Water Efficiency: Water efficiency includes the practices, techniques, and technologies that extend water supplies either directly through water savings or through substituting alternative supplies such as reuse. For purposes of this document, water efficiency is inclusive of water conservation and is used instead of "water conservation." The term water efficiency captures the essential objective of a local plan which is to improve the efficiency of a municipal demand and water supply system. Water efficiency includes both system demands and customer water demands. Water Efficiency Activities: Traditionally water efficiency activities have been referred to as water conservation measures and or water conservation programs. For purposes of this document, measures and programs are replaced with water efficiency activities. Water efficiency activities Source: American Water Works Association. 2006 Water Conservation Programs — A Planning Manual. Manual of Water Supply Practices M52. First Edition. WTP0 encompass all efforts to either save water or improve efficiencies within a water supply system.
