The mileage on Truck 20 is currently 95,000 and it is six years old, which is within the vehicle replacement policy parameters of age and mileage (five years or 50,000 miles). Historically Light & Power would receive a standard utility trunk with a standard utility truck bed. This year L&P worked directly with Lead Mechanic, Jim Nelson, to review and meet our specific needs. We are requesting an increase of $13,112 to the amount in the replacement budget for the Light & Power Duty Truck 20. The additional costs will result in a better engine, increased work efficiencies and improved safety. Attached are pictures with explanations on the differences between a standard utility truck and an electric utility truck. The following quotes were received from three vendors for the truck: Fort Collins Dodge 3835 S. College Avenue Fort Collins, CO 80525 Dodge 3500 Ram, $59,112 Markley Motors, Inc. 3325 So. College Avenue Fort Collins, CO 80525 GMC 3500 Sierra, $65,378 Spradley Barr 2601 So. College Avenue Fort Collins, CO 80525 Ford F350, $65,870 Budget: $46,000 Vehicle Replacement Fund (635-700-435.34-42, page 154) $13,112 Additional funding will be moved from 502-6100-520.28-08, "SOURCE OF SUPPLY", to 502-7001-580.33-98, "OTHER CAPITAL EQUIPMENT". This year's lower electric demand has reduced "SOURCE OF SUPPLY" costs leaving enough funds to cover this additional amount. Recommendation: Staff recommends purchasing the Dodge 3500 Ram from Fort Collins Dodge for the purchase price of $59,112 to the Town Board, to be included on the Consent Agenda at the September 25, 2012, Town Board meeting. 2 Standard hooks for overhead wire LED Down Lighting ro,im, 14(4n ri k Flom4",, 3, i'":".4c4ArIc ruck.

When a winch cable breaks, it acts like a slingshot presenting a danger to crew members and equipment. Last year we had four cables break. Also, the truck bed is lower for crew members to more safely lift heavy equipment. There are a number of other details which can be discussed explaining the advantages of changing our specification from our standard utility truck to an electric utility truck. We are available to discuss this further or meet next to our trucks to better describe our needs. 1 Report TOWN oF .177_,STES PARK 011101000100901111090000001019,00r UR1101rU r01011111111101000110099 00° ru 110001...„ „ cc c • 11110 111111111 r 1111111111 900 c.191utuu, rcruccuccucc „„ rou 1111,111,11,„ „ 1111111111111111111111111111111'11111111111 11119111111110111111111111111111111110011,1110011,1 911, ul 1"'1"1111111111UU119111111111111111,11.„).991,9„„,,c.„,c,„............„ 01,111110001911-lucuulucc,,,,,,,, „„1„,gui919 99-uccuccul,,,, „„„, c 11 rilloloupplUullucluici,91,19.1clucuou.1111111,1111111,1, cuuu,„,„„cculluccuullulluclu u0000 00000U1 111.01.1 .111111111,111111111111111111111.111111.1.111111,„I' „11' c111111,111111111111111,1111111111 To: Public Safety, Utilities & Public Works (PUP) Committee Town Administrator Lancaster From: R.

In addition to some minor changes, the CWCB has requested the document be opened for public review and comment for 60 days. The Public Notice to be published next Wednesday, September 19th, is shown below. Attached is a red -lined copy of the conservation plan. The following is a list of the changes that were made (for easy reference): • Page 9, consideration of a conservation -based rate structure. • Page 30, the State requested water reuse be included. This is addressed in more detail on page 33. • Page 31, additional detail added for clarification of water -saving fixture use. • Page 33, addresses "Reuse". • Pages 33 and 34, address low -flow toilets. • Page 34, adds commitment to revisit water audits in the next revision. • Page 37, adds more detail on individual metering of multi -family units. • Pages 46 and 47 have many changes. For clarity, they are printed twice: the first with all changes tracked and the second showing the final version. Staff will review any public comments received with the Public Safety/Utilities/Public Works Committee at the October 1 1 th and November 8th committee meetings. All public comments will be addressed at the November 27th Town Board Meeting. Budget: N/A, funding for this work was completed in 2011.

The approach used to develop this Conservation Plan follows the guidance provided by the State of Colorado Water Conservation Board. Similar to other resort communities in Colorado, the Town of Estes Park has a permanent year -around population that typically doubles and sometimes triples in the summer due to the large influx of visitors. As a result, the water system must be capable of serving a wide range of potable water demands that result from direct consumption by the increased population. In contrast to other cities in Colorado, very little water demand in Estes Park is attributable to irrigation. Landscape plantings are at high risk of survival due to the grazing of natural wildlife (elk and deer) so typical landscaping throughout the Estes Valley is natural vegetation. The small amount of landscaping in the Town is generally limited to municipal parks and property. This situation makes the Town unique with respect to conservation measures that are available to provide any significant water savings. This plan is limited to the use of multiple conservation measures having relatively small amounts of water savings. Sections two through four contain background information taken from previous planning and evaluation work. The following list includes the reports from which information is drawn. • Potable Water Demand Project, Town of Estes Park, July 12, 2007 • Water Treatment Facilities Evaluation, Town of Estes Park, January 2007 • Estes Park Water Treatment Facilities, Phase 2 Study, Town of Estes Park, July 2010 • Water Cost of Service Study, Town of Estes Park, December 2010 The plan was developed by the Conservation Plan Committee, whose members include the following: • Reuben Bergsten, Utilities Director for the Town • Jeff Boles, Water Superintendent for the Town • Diana Beehler, Laboratory Technician for the Town • Sarah Clark, Project Manager at HDR • Jennifer Stillman, Project Engineer at HDR The plan was presented to the public at the Utilities Committee monthly meeting and again at a public Town Board meeting where it was approved.. 2.0 Existing Water System Profile The following sections discuss the water system physical characteristics, sources of water, limitations, water costs, current policies and planning initiatives, and current conservation efforts. Wit toy C s erva Pla n 2.1 Physical Characteristics of Existing Water System The Town of Estes Park water system serves water to customers in the Estes Valley with an estimated service area of 17.58 square miles. The boundary of the Estes Park water system service area coincides roughly with the boundary of the Estes Valley. The majority of the water system is located below the "blue line", which is the maximum customer service elevation allowed for gravity fed services, i.e. 100 feet below the storage tanksHydraulic Grade Line (HGL) The existing water system is composed of two (2) water treatment plants, nine (9) storage tanks, two (2) clearwells, and more than 100 miles of pipeline. The water system currently serves approximately 4,000 residential connections and 850 commercial connections. A map of the distribution system is shown in Figure 2-1, which depicts the service area, distribution system facilities and pressure zones within the system. Two water treatment plants serve the Town of Estes Park: Marys Lake Water Treatment Plant (MWTP) and Glacier Creek Water Treatment Plant (GWTP). The MWTP is located at the south end of the water distribution system, adjacent to Marys Lake. The MWTP was originally constructed in 1992 and was renovated in 2010 with membrane technology. The plant normally obtains its raw water supply by gravity from the BOR tunnel that feeds Marys Lake. The plant can also pump raw water from Marys Lake through the Marys Lake pump station which was installed in 2003 . The design capacity of MWTP is 4 million gallons per day (mgd), but the plant cannot be operated at that rate year round due to water rights constraints on the BOR supply and due to wastewater discharge limitations. Originally constructed in 1972, the GWTP is a conventional treatment plant located along Glacier Creek. with access through the YMCA campground. Minor improvements have been made to the treatment process since the original construction and the filter media was replaced in 2003. The design capacity of the plant is 4 mgd, with the exception of the filters which are rated for 6 mgd. However, plant staff report that the current maximum treated flow is about 3.6 mgd. Runoff events in the watershed are particularly challenging for GWTP due to extremely low water alkalinity, low water temperature, undesirable color and lack of robustness in the treatment process. Similar to the MWTP, the Town's available water rights on Glacier Creek limit the length of time that the Town can operate GWTP at maximum flow. The Town's distribution system has 9 water storage tanks and 2 treatment plant clearwells. The Marys Lake storage tank is divided into two sections. One section serves as the clearwell while the other serves as storage. Table 2-1 is an inventory of those facilities, including pressure zones served, capacities, elevations, dimensions and general construction information. Locations of these storage facilities are shown in Figure 2-1 2 .L" or Coto oi vaGon Pia tr fiR Figure 2-1 Existing Woter Sys tern u.. 00 z • F t' P odC) ,...:C'' 7,987 (HIGH) a, ti 01 N 00 N o 6 0, 7h 0 oti I-- 0 at Round IA „ , 0, 1963 I Above Ground Steel 0 "r2 0 o i2 f., Pq 1 g 0 0 oo 8.250 0 '0 N 0,- c•c.' oi ,-, od• ,i-, ,.o 6 8,352.8 '4, co (-,-, rn of5 , ol 27.0 I E 6 oi Buried Concrete it ,1:1 o -Thunder Mountain Zone- 00c'? 8.435 8.330 8.370 (HIGH) 0 N rn . o a, r-: 4,1 N 8,449.25 8.435.25 40 , , , 14 1985 Buried :.21 tO'' o U ..--. o *0 2, 3. 4, 7 8.220 o 06 0 N — 7,719- 8.120 — N 00 N oc; — N c<1 8 el . 86 I .0 co 0 • o- o, 0, ......

Water Conservation Plan FDA The Estes Valley is largely surrounded by public land (Rocky Mountain National Park and Roosevelt National Forest) and therefore future growth is limited to the boundaries of the water system service area. Current population in the Estes Valley varies significantly from winter to summer, with an estimated peak population of 22,350 occurring during the summer tourist season. The estimated build - out population is 32,624 by 2030, a 46% increase. The Town's most recent water demand study was completed in 2007 (Potable Water Demand Projection, HDR, July 12, 2007) as part of a broad water plant evaluation and planning effort. Metered water usage by month as well as total water treatment plant production in 2006 is shown in Figure 2-2. The data show that residential water usage and commercial water usage are roughly the same at the present, and the usage follows the same seasonal demand trend. The difference between the water treatment plant production in Figure 2-2 and the total metered water is largely due to system losses and also partly due to wholesale customers (bulk and dispenser) whose meter records were not included. System losses include water used or lost in the treatment plant and distribution system. Losses in the Town's water system have stabilized and are not expected to increase as long as the distribution system continues to be maintained. The distribution system does have a number of "bleeders", which are set to bleed water from the system during the winter to keep the distribution pipes from freezing. Their usage is also metered and shown in Figure 2-2.

The transmountain water comes from agreements with the Bureau of Reclamation (BOR), Colorado Big Thompson Project (CBT), and Windy Gap. The native water rights are all located on tributaries of the Big Thompson River. The two sets of rights, transmountain and native, are associated with the raw water supply to the MWTP and the GWTP, respectively. The transmountain water is delivered to the Town by means of the BOR facilities which include the Rams Horn Tunnel (hereafter referred to as the "tunnel") and Alva B. Adams Tunnel from Lake Granby to Mary's Lake. The raw water source for the Town's newest plant, MWTP, is piped directly from the tunnel to the plant. The BOR typically shuts the tunnel down for 2-4 weeks during October for maintenance. During the tunnel shut down, the Town can rely on a pump station with an intake in Mary's Lake to pump raw water to MWTP. The BOR agreement dictates that the Town use their 500 ac-ft allotment of water at the MWTP prior to using their other transmountain water. Due to this agreement, the Town does not have an annual surplus of BOR water. In addition, a portion of the Windy Gap water is used as part of the Town's Augmentation Plan. The Town does have an annual surplus of CBT and Windy Gap water after the MWTP and augmentation demands are fulfilled. A portion of this surplus is sold to smaller water users who have agreements with the Town. In the past, the Town's native water rights served as direct raw water diversions to three separate water treatment plants. Since then, the Fall River Water Treatment Plant and the Black Canyon Water Treatment Plant have been decommissioned. The GWTP is a 3 mgd operational facility with dedicated water rights for 1.3 mgd on average. Since only the GWTP is still operational, a portion of the remaining native water rights have been transferred to Glacier Creek. (Not all of the Fall River agricultural water rights have been transferred to date.) All of the Town's native water rights have junior priority. Consequently, the Town's rights are out -of -priority most of the time. In order to overcome this obstacle, the Town has adopted an Augmentation Plan. The Plan was implemented in 2001 and allows the Town to divert their junior native water rights year-round in exchange for augmentation with Windy Gap water. The average exchange ratio is 10:1, i.e. 100 ac-ft of treated junior native water rights is replaced by 10 ac-ft of Windy Gap water. It is important to note that BOR and CBT water cannot be used for augmentation at this time. The native water rights associated with GWTP currently have an instantaneous withdrawal limitation of 4 cubic feet per second (cfs), which is equivalent to 2.58 mgd. The Town is planning to appropriate additional water rights for the GWTP to allow the plant to produce 4 mgd. Unlike GWTP, the MWTP does not have an instantaneous withdrawal limitation on its transmountain water rights. Therefore, MWTP could produce 4 mgd on a peak day/s if necessary. Following the purchase of additional water rights for GWTP, the Town's combined water supply capacity will be 8 mgd, which satisfies the projected buildout peak day demand of 7.9 mgd. (Section 3.0 will address the demand projection used to arrive at this value.) Consequently, there are no additional water supply purchases identified within the planning window of this Conservation Plan and water supply and water rights will not be further addressed. 6 Water Conservation. Plal Ink 2.3 System Limitations The greatest issue of concern to the Town's water system is a major renovation project that is needed at GWTP in order to replace aging infrastructure and address upcoming EPA water regulations. Two recent engineering studies that evaluate existing water treatment facilities have been completed by the Town. The first of the two studies, the Water Treatment Facilities Evaluation, included condition assessments of the two water plants and developed a plan to meet the long-term projected water demand. Options for improvement or replacement of the two plants were evaluated in this study, with the final recommendation to improve and expand capacity at the MWTP utilizing submerged membranes, reserving the decision whether to improve or replace the GWTP until more information could be obtained regarding the cost of that effort. Since this study was completed in 2007, the MWTP has been upgraded with submerged membranes and now has a treatment capacity of 4 mgd but operates at 2 mgd peak flow. The current restrictions on operating at design flow are tied to the availability of waste discharge capacity (and the cost to discharge). The second of the two studies, the Water Treatment Facilities Phase 2 Study, was completed in 2010.. This study is an in-depth evaluation of the facilities at the GWTP, with the objective of making a determination whether to improve the plant or replace it entirely, and if it were to be replaced, at what location. GWTP is at significant risk for meting the drinking water quality regulations under certain water quality conditions which generally occur during runoff. In addition, the plant has the potential for being reclassified, after the 2016 round of sampling, in a treatment bin for the LT2ESWTR that requires additional treatment beyond conventional treatment. The plant is composed of aging equipment, buildings and concrete tanks, so that repair or upgrade without complete replacement is not cost effective. A significant amount of work is required to demolish and replace the GWTP on the existing site. The current plan is to move towards complete replacement for the plant, probably by 2021, with a treatment capacity of 2.65 mgd, which is equivalent to the water rights limit for instantaneous withdrawal at Glacier Creek of 4.1 cfs. (Note, the instantaneous withdrawal rate for GWTP has since been clarified as 4.0 cfs, which is equivalent to 2.58 mgd.) 2.4 Water Costs and Pricing The water utility provides only potable water to its customers. Between 2000 and 2009, the peak billing years occurred in 2000 and 2007. The water utility has seen a steady decline in volume of sales in recent years. The following illustrates the decline of the most recent year's water use reduction: 2007 to 2008 2008 to 2009 2009 to 2010 0.5% reduction 1% reduction almost 2% reduction There have been no major reductions in customers to account for this decline. The decline in water use translates to a decline in revenue, which drives the need for greater rate adjustments to fully fund the operating and capital needs of the system. This trend holds true nationwide for residential customers and is due to a number of factors, but in particular to water efficient plumbing fixtures (toilets, washing machines and dishwashers). The national plumbing code has new low water use requirements in place for washing machines since 2010 and dishwashers beginning in 2011. This trend (decline in residential 7 Water Conservation Plan FiR water use per household) is expected to continue as appliances are replaced over the next decadel. A trend in less people per household and the economic downturn are two other elements playing into these household usage and billing reductions. The Town has also been actively reducing unaccounted for water over the past several years. In 2010, the Town completed a comprehensive water rate study and review of water system development charges. As part of the comprehensive rate study, existing rates were reviewed and analyzed for each customer class of service. The existing rate structure is comprised of a monthly base charge that is dependent on the size of water meter for all classes of service. In addition to the base charge, there is a usage charge for each 1,000 gallons of water consumption. Outside the Town limits, rural customers pay an additional 60% for service. The Town has four customer classes: residential, commercial, pumped flow, and bulk water. The bulk water customers are essentially subdivisions that are served by private water companies who have requested water service from the Town. The bulk water customers pay their system development charge over a period of twenty years once they are connected to the Town's system and receiving water service. One important revenue shift for the Town in 2011 is that this "surcharge" revenue from bulk water customers will discontinue by $22,000 as two of the bulk water customers have completed their 20-year payment period. This equates to slightly more than half a percent reduction of overall rate revenue. During the rate design phase of the 2010 study, discussions of goals and objectives for the utility were undertaken. The primary objective established by the study was to maintain revenue stability, and provide adequate revenue for operations and capital needs. At the same time, the utility has seen a decline in water consumption in recent years. While conservation billing rate options were discussed and explored, the utility management felt that with the existing reduction in consumption currently taking place, a conservation designed rate would de -stabilize the revenue stream. Since revenue stability was the key objective of the study, an adjustment to the meter charge was developed. This involved applying the American Water Works Association (AWWA) meter capacity weighting factors for a 3/4- inch meter to the meter charges. These weighting factors reflect the capacity of the meter with respect to the potential demand on the system. Thus, a customer with a larger meter pays a larger meter charge, or base rate, to account for the greater demand they place on the system. Since this adjustment would create a greater rate increase to customers with larger meters, the proposed rates were developed to be implemented over a three-year period. Overall, the 2010 rate study showed that the level of adjustment needed to meet the revenue requirement was 6.8% per year for the next several years. The Town Trustees felt that this increase was too high and that the meter charge increases would further penalize customers with larger meters at an economically sensitive time. Therefore, the Town decided to maintain the existing rate structure and apply a 5.6% revenue adjustment to each rate component (the meter charge and the consumption charge) for 2011 through 2013. If the Town considers implementing a conservation -based rate structure in the future, a seasonal rate appears to be the most appropriate from a rate design perspective. This type of rate would have the volumetric, or consumption -based, rate component increase in the peak season (summer), when the Town's population swells with tourism. This form of rate structure provides increased cash flow closer Trends in Residential Water Usage and its Impact on Water Utility Financial Planning, American Water, Gary Naumick, P.E., AWWA Utility Management Conference, Denver CO, February 2011. 8 Water Conservation Plan to the time when system operating costs are higher, due to increased pumping and chemical usage to meet peak demands,A c,c!,,n:yiniqu Lbw:4 1:alc'......sn'uct 0 !y,,\.v ill k;., (..',Lnqkic!,1 in .111c211;;;),slyps,,liA, (a: llik; Cg,t;irYWIiPI Table 2-2 provides a summary of the water utility rates for all customer classes of service, including the previous 2010 rates and the newly adopted 2011 rates.

On average, an urban residential customer with a 3/4-inch meter uses approximately 5,000 gallons of water in a month. Under the present rates, this customer would pay $36.75 per month. Under the Board adopted rates that cost will increase to approximately $38.80. The Town's utility bills include both water and electric service charges, on a monthly basis. The billing department cannot distinguish between the water and electric utilities for numbers of delinquent billings. While water bills are highest in summer, the electric utility bills are highest in winter, due to heating requirements. Delinquent bills have increased somewhat since the economic downturn. The total number of delinquent bills issued from 2009 to 2010 increased 13%. However, for the first five months of 2011 compared to the first five months of 2010, the number of delinquencies issued has dropped 16%. Overall, levels of delinquencies appear to be remaining relatively stable. The Town has incurred the same increase in foreclosures and bankruptcies in recent years that are seen nationally, and along with that, some billings to write-off, but nothing unusual has transpired in the recent past. This completes the discussion of the Town's water utility billing and revenue trends. A more detailed discussion of the development of the comprehensive rate study can be found in the Town's Comprehensive Water Rate Study Final Report, January 2011, HDR. 9 Wafer Con.,rrlvr'ifion 2.5 Current Policies and Planning Initiatives The Town currently has a 3-stage water conservation plan that was developed after the drought in 2002. Table 2-3 summarizes the 3-stages and Table 2-4 summarizes the specific water usage restrictions during each of the stages. Table 2•,3 3-Stage Conservation Plan Summary Stage Description Conservation Measures 1 This is the normal mode of operation. Voluntary water conservation measures are suggested to encourage prudent water use, but none are mandated. Voluntary conservation measures are included in this stage to embed water efficiency programs into the fabric of the community and achieve permanent reductions in per capita water use. Long-term water demand management programs include both structural and non-structural measures. 2 This stage is triggered by the loss of one of the water supply sources and a likely reduction in the other supply source. Mandatory water restrictions are in effect to reduce water demands. Water rates are increased to recover the same amount of revenue as existing rates recovered under Stage I conditions. Immediate action is necessary in Stage II to reduce water demands. The Town's primary tool for achieving short-term reductions in water use is to declare that Stage II conditions exist and to enact restrictions to reduce water consumption until adequate supplies are available. The goal of the restrictions is to assure that water is continuously available to all customers for minimal irrigation and essential uses that protect the health, safety and welfare of the public. 3 This stage is triggered by the loss of both water supply sources. Severe water restrictions are in effect and water rates are drastically increased to recover the same amount of revenue as existing rates recovered under Stage I conditions and to penalize unnecessary water usage. 10 Water Con orvafion Plan Table 2.4 ,Summary of Water Restrictions by Conservation Stage Conservation Measures Stage I (Normal) Stage II (Moderate) Stage III (Emergency) Impose water rate surcharge No No Yes Allow turf Irrigation Yes Yes No Voluntary watering days are designated Yes N/A N/A Mandatory watering days are designated and should be observed N/A Yes N/A Voluntary landscape/lawn non- watering between 10 am and 6 pm.

If this requirement is implemented, the Town may revisit and further refine the 3-stage plan outlined above to address additional issues such as modified drought rates. It should be noted that CWCB does offer grants to assist water providers in development of these mitigation plans. The Town has completed a number of planning documents over the past decade which have been referenced throughout this Conservation Plan. With the exception of a potential Drought Mitigation Plan for CWCB, the Town does not intend to develop any additional planning studies in the near future that would impact conservation efforts. 2.6 Current Water Conservation Activities Historically the Town has promoted water conservation in the community using two means: posting of conservation information on the Town's website and distribution of free water saving plumbing fixtures. Conservation information on the Town's website includes a summary of the Town's 3-Stage Conservation Plan (see Section 2.5), a list of conservation tips, and an advertisement for a "free water - saver kit". The Town intends to maintain the conservation information on the website, but there are no plans to update the website at this time. 11 IIV for rvation Plan "D The "free water -saver kits" referenced on the Town website currently consists of a variety of water saving plumbing fixtures as sold by Niagara Conservation and distributed by the Town to its customers for free. The Town currently maintains an inventory of the following Niagara fixtures/accessories: 1.5 gpm showerheads, toilet tank bladders, 1.5 gpm faucet aerators, 0.5 gpm faucet aerators, and dye tablets (for toilet leak detection). The Town distributes these items for free to any customers who request them and some special interest groups such as the Recreation District. This program has been in place now for 5 years and the Town will continue to utilize this program in the future as part of its conservation efforts. 3.0 Historic Water Use and Demand Forecast The Town completed a demand forecast as part of their "Potable Water Demand Projection" report in 2007 (hereinafter referred to as the "2007 Demand Projection"). The majority of Section 3.0 was extracted and streamlined from the 2007 Demand Projection to serve as the basis of water use characterization and demand forecasting for this Conservation Plan. The figures and tables presented in this section are based on data collected through 2006. The Town has not experienced any significant changes in the parameters that were used in the 2007 Demand Projection (population growth rates, water usage, land use, etc.) and therefore the demand forecast that was produced as a result of that study is considered to still be valid. 3.1 Service Area Population The Town of Estes Park is somewhat unique in that the population doubles and sometimes triples in the summer due to the large influx of visitors. In general, the population of the water service area can be divided into four categories: permanent, transient, non -transient, and wholesale. The Town has prepared a statistical population analysis that is provided to the Colorado Department of Public Health and Environment (CDPHE). The analysis estimates the population of the Estes Valley in both the peak season (May -September) and the off-season (October -April) for each of the four categories listed above. (A copy of the statistical population analysis, titled 2006 Population Fact Sheet and Projections, is provided in the 2007 Demand Projection.) Some of the population data from the Town's population analysis was incorporated into the 2007 Demand Projection to serve as the current population basis. This data was projected into the future as part of the study. 3.1.1 Permanent Population The historic permanent population of the Town is best -reflected in the population numbers from the U.S. Census Bureau. Table 3-1 summarizes the Census population numbers and estimates for the Town, Estes Valley, Larimer County, and the State. Figure 3-1 shows the annual percent growth for these entities as well as other Colorado communities and counties as estimated by various agencies. A copy of the population data used to compile Figure 3-1 is provided in the 2007 Demand Projection. 12 fak "rable 3-1 Census Population Summary Water Conservation Plan Year Town of Estes Park Percent Annual Change Estes Valley Percent Annual Change Larimer County Percent Annual Change State of Colorado Percent Annual Change 1950 1,617 - - - 43,554 - 1,325 1960 1,175 -3.1 - 53,343 2.0 1,754 2.8 1970 1,616 3.2 3,554 - 89,900 5.4 2,225 2.4 1980 2,703 5.3 4,070 1.4 149,184 5.2 2,908 2.7 1990 3,672(1) 3.1 6,044 4.0 186,136 2.2 3,303 1.3 2000 5,413 4.0 8,889 3.9 251,494 3.1 4,301 2.7 2010 8,0132 4.0 11,500'2) 2.6 - - - - Notes: (1) The U.S. Census Bureau reported a populatit n of 3,184 for the Town in 1990.

The Town estimated the 2010 population to be 8,013 in the Town itself and 11,500 in the 1 3 I/1/ator (;r>trr, Iry tiorr Flan hE Valley, representing 4.0% and 2.6% average annual growth, respectively from 2000. Another means to analyze growth in the Valley is the number of water accounts added each year. The total number of water accounts increased from 4,146 accounts in December of 2000 to 4,838 accounts in December of 2006. This increase represents a 2.6% average annual growth rate between 2000 and 2006, which is in agreement with the Town's estimated growth rate for the Valley. It is important to note the extreme variability in the population growth rates for the region during the past 50 years, as well as the potential for a deceleration in growth in the future. 3.1.2 Transient Population Tourists make up the transient population in the Town. This group is comprised of both day visitors and overnight visitors. During the summer of 2006, the Town completed a survey to examine the visitor profile (Estes Park Summer Visitor Survey 2006, November 2006, RRC Associates). The survey found that the primary attraction for visitors is still Rocky Mountain National Park (RMNP), although activities such as wildlife viewing and other outdoor recreation activities also have a high importance. Roughly 30 percent of visitors to the Town were from Colorado, with the remainder coming from all over the country. The total number of out-of-state visitors increased from 64 to 70 percent since the previous survey ten years earlier. The survey results support the assumption that the transient population in the Town correlates closely with the total number of visitors to RMNP. Furthermore, the number of visitors to the Town is more influenced by national growth trends and trends in visitation to National Parks then it is by growth trends within Colorado. To obtain reasonable projections for the number of RMNP visitors, historic data for visitor numbers were obtained. RMNP staff has estimates for visitor numbers dating back to 1915. However, in 1984, RMNP changed their estimate methodology to adjust for the number of persons per vehicle. For this reason, only data collected after 1984 is shown in Figure 3-2. Visitation to RMNP has leveled off in the past 10 years and been on the decline since roughly 1999. A copy of the RMNP visitation records is provided in the 2007 Demand Projection. HDR spoke with the Director of Planning for RMNP regarding future visitation trends during the preparation of the 2007 Demand Projection. It was the Director's opinion that growth would continue to be slow for the next 10 years, reaching approximately 3.5 million annual visitors by the year 2017. The reason for this decline, in the Director's opinion, is due to generational differences and a general decline of interest in the National Parks. However, the trend may also be related to the rising cost of gasoline and increased fees to RMNP. For the 2007 Demand Projection, the future visitation trends of RMNP were estimated based on the Director's understanding of future visitation as well as historic visitation data. If the growth rate between 1984 and 1999 were to continue from 2006 forward, the projected annual visitors to RMNP would reach 4.5 million by approximately 2030, as shown in Figure 3-2. Additional data to support this opinion could be collected by examining visitation trends in all of the National Parks with a possible focus on the National Parks in the west. 14 t iR 6.0 17; 5.5 0 5.0 LI 4.5 0 4.0 0 lk 3.5 E z -6 3.0 ct 2.5 2.0 Water Conservation Plan Figure 3,-2 Historic Annual Number of Visitors to Rocky Mountain National Park Growth trend from 1984 to 1999 4.5 million visitors in 2030 if growth trend recovers to historic rate 1980 1985 1990 1995 2000 2005 2010 2015 2020 Year 2025 2030 Another source of information used for validating the transient population in the Town is the Estes Park Convention and Visitor's Bureau (CVB). Currently the Town has lodging accommodations for 3,000 people. The CVB refers to this as "3,000 pillows" since various lodging units can accommodate different numbers of guests. (This estimate includes rental condos.) The Town currently has a surplus of lodging inventory and the CVB is unaware of any significant future development plans for lodging. This information supports the concept of estimating the transient population based on the number of visitors to RMNP and placing an upper bound on the transient population projection. The CVB estimates that only 25 percent of visitors to the Town do not visit RMNP. This indicates that the RMNP visitor numbers remain the best parameter available to estimate the transient population in the Town. The Town used to be completely booked every summer day roughly 10 years ago, but it is rarely booked full anymore with the exception of major holiday weekends. The CVB's current primary goal is to attract more tourists to the Town in the off-season. The Town is not trying to expand its accommodations infrastructure, but instead is trying to fill what they already have. Increasing occupancy in the off-season does not impact the development of the demand estimate as future water treatment capacity is calculated using the peak day demand. The Town's population analysis estimated the transient population using percentage estimates of RMNP traffic, accommodation bed counts, and estimates of unaccounted for visitors (those who do not visit the Park and do not stay overnight in the Town). Using this information, the Town estimated that the 2006 transient population was 10,789 visitors per day in the peak season and 2,756 visitors per day in the off- season. 15 1/1/,r Cot otv,aPlot; FL:rn For the 2007 Demand Projection, the most likely estimate of the current transient population was based on the estimate by the Town. Since this group of the population is the most difficult to estimate accurately, both low and high estimates of this value were also developed. The high estimate of the transient population was based directly on the RMNP visitors during the period from May through September, 2006. Monthly visitor numbers for 2006 were taken from the visitor summary on the RMNP web site. The daily average number of visitors during the peak season was 15,377 in 2006. As a low end estimate of the transient population, half the number projected by the Town's population analysis was used (5,394), reflecting the high variability potential in the Town's parameters. This falls roughly between the Town's estimates for the transient population in the off-season and peak season. 3.1..3 Non -Transient Population The non -transient population is comprised largely of workers who commute into Town. The major employers in the water service area who were interviewed by the Town for the population analysis included the Park School District, Estes Park Medical Center, Town of Estes Park, Eagle Rock School, Harmony Foundation, and the Estes Valley Recreation District. The number of non-residents within these organizations ranged from 10% to 50%, with an average of 27%. The Town also estimated the unrecorded fraction of the non -transient population who do not work for the employers listed above. In contrast to the typical peak season population increase, the population of non -transients is higher in the off-season due to the schools being in session. The Town estimated the 2006 non -transient population to be 398 persons per day during the peak season and 666 persons per day in the off-season. To simplify the analysis, it was assumed that the estimate developed by the Town was reasonable as it was based on interviews with major employers. Consequently, the peak season estimate of 398 people was used for the analysis. 3.1.4 Wholesale Population The Town provides wholesale water to four bulk wholesale customers and to rural customers via a dispenser located in Town. There are currently four bulk wholesale customers including Windcliff Property Owners Association, Hondius Water Users Association, Park Entrance Mutual Pipeline Water Company, and John Timothy Stone Association. The Town's population estimates for the wholesale bulk customers are based on metered sales and an assumption of per capita water usage. Using this data, the Town estimated the wholesale bulk water customers to be 796 persons per day in the peak -season and 482 persons per day in the off-season. In addition, the Town estimated that the existing wholesale bulk water customers were at 80% of buildout with no future plans for expansion. The wholesale population is not a significant component of the total water service area population. To simplify the analysis, it was assumed that the estimate developed by the Town is reasonable and the peak season estimate of 796 people per day was used. 3.1.5 Other Populations Not Included in Projections Several other populations exist inside and around the water service area, including the YMCA of the Rockies, Camp Cheley, and Prospect Mountain Water Company. The YMCA of the Rockies recently constructed a new water treatment plant and is not expected to require permanent Town water service in the future. Camp Cheley has their own water system, but is currently hauling water from the Town dispenser. The Town has discussed serving Prospect Mountain (approximately 350 homes and 0.03 mgd usage) in the past. It is possible that when the Prospect Mountain contract with the Bureau of Reclamation is up for renewal this year, discussions will resume, but this population was not included in the population projections. 16 IA✓a(or CTonsorvai'Olt Plan FiR The Town has existing emergency agreements with the YMCA of the Rockies (up to 0.43 rngd) and with Prospect Mountain Water Company to provide water on an emergency request. Although these customers are not included in the population projections, they are included in the buildout demand to ensure that the water treatment plant has capacity for both the Town's peak day demand as well as emergency service to both the YMCA and Prospect Mountain Water Company. (Since the 2007 Demand Projection, the Town has entered into discussions with Prospect Mountain regarding becoming their permanent water supplier.) The Town is currently in discussion with the National Park Service regarding future connection of the RMNP headquarters facilities to the Town's water system as a wholesale customer. Based on the average peak season usage by RMNP since 2000, adding the Park as a wholesale customer is the equivalent of 375 people per day to the population projection. Town staff indicated that RMNP could become a wholesale customer in the near future. This demand does not have a significant impact on water treatment plant capacity. Therefore, the population was not included in the projections, but the demand was included in the buildout demand calculation. 3.1.6 Population Growth Rate Projections Table 3-2 below summarizes the probability of projected growth rates for the various populations served by the water system as well as the basis for the projected growth. The 2006 peak season population for wholesale bulk and non -transient populations was based on the population analysis by the Town. The 2006 peak season population for transient visitors was assigned a level of variability as part of the analysis.

Data from 1993 were also plotted for comparison. This figure shows the seasonality of potable water demand which has two components: increased population in the water service area in the summer time and increased water demand by the population in the summer as compared to the winter. The figure also shows that the pattern of seasonal usage has remained relatively consistent for the past twenty years. Note that the maximum peak day production occurred in 2002 (4.3 mgd), which is considered by the water industry to be a representative year for drought conditions in Colorado. 5.0 - 4.5 4.0 c, 3.5 3 3.0 0 w >,2.5- .s O • 2.0 1.0 0.5 0.0 Figure ,3-3 Seasonal Water Treatment Plant Production 01993 ■ 2001 ion 2002 ❑ 2003 2004 ®2005 2006 1 2 3 4 5 6 7 8 9 10 Month 12 Potable water demand is typically analyzed by determining the average annual day demand and applying a peaking factor to estimate peak day demand. For the 2007 Demand Projection, the average day demand in the peak season (May -September) was used along with a peaking factor representing the ratio of the peak day demand to the average demand in the peak season. This adjustment was made because the growth rate of the peak season population is more easily estimated for this community than the growth rate of the average annual population. Figure 3-4 shows the historic peak day demand, average demand in the peak season, and the peaking factor from the Town's treatment plant production records. Note that demand decreased significantly following the drought in 2002. Since this time, the demand appears to be rebounding back to the pre -drought conditions. Like many communities in the region, this may reflect voluntary conservation practices. However, there is not enough data currently available to solidify this conclusion. Table 3-3 shows the historic minimum, average, and maximum values for each 18 Vliater Conservation Plan „ A of these parameters. The values listed for the peaking factor (ratio of peak demand to average demand in peak season) were used as the low, most -likely, and high values in the 2007 Demand Projection. 5.0 4.5 a 4.0 2 3.5 c 3.0 CI 2.5 w .o 0 a. 2.0 1.5 1.0 0.5 0.0 Figure 3-4 Historic Treatment Plant Production .4(km Peak Day Demand ...- Avg Day Demand in Peak Season -a-Peak/Avg Ratio (Peak Season 1."'"•'0"'°"4111%......e....11- Potential conservation effects 1993 1995 1997 1999 2001 Year 2003 2005 Table 3-3 Historic Potable Water Production (1993-2006) Historic Occurrence Peak Day Demand Avg.

The data show that residential water usage and commercial water usage are roughly the same at the present, and the usage follows the same seasonal demand trend. The difference between the water treatment plant production in Figure 3-5 and the total metered water is in small part due to wholesale customers (bulk and dispenser) because their meter records are not included here, and is largely due to system losses. System losses include water used or lost in the treatment plant, 19 I/1/a Coosiirvation Plan' FiR conveyance, and distribution. Losses in the Town's water system have stabilized and are not expected to increase as long as the distribution system continues to be maintained. Bleeders are set to bleed water from the system during the winter to keep the distribution pipes from freezing. Their usage is also metered and shown in Figure 3-5 (repeated here from Section 2.1 for the reader's reference). Potable Water Usage (Millions of Gal Per Mo 90 80 70 60 50 40 30 20 10 Figure 3-5 2006 Potable Water Usage 4.-WTP Production Total Metered Residential Metered Commercial Metered Bleeder Metered 2 3 4 6 Month 7 8 9 10 11 12 Per capita water demand can be calculated by distributing the water treatment production over the population to arrive at a usage per customer. Using this method, each customer is allocated a portion of residential and commercial demand as well as system losses. For the 2007 Demand Projection, the 2006 average water treatment plant production in the peak season (2,078,000 gal/day) was distributed over the peak season population (22,352) to arrive at a per capita usage rate of 93 gallon per capita per day (gpcd). To establish a low value for per capita usage, the average water plant production in the off- season (1,047,000 gal/day) was distributed over the off-season population (14,273) to arrive at a per capita usage rate of 73 gpcd. The high value for per capita usage was established by examining the ratio of peak day demand in a drought condition (2002) with the 2006 peak day demand (year that population data is available). The peak day demands were 4.31 mgd and 3.53 mgd, respectively, representing a 22% increase. This is considered a conservative estimate of the effects of a drought on average peak. day usage. There is some impact from population growth between 2002 and 2006 that may have also caused the peak day usage to increase during this time period. However, the effect is considered minimal and counter -acted by potential voluntary conservation efforts following the drought of 2002. The 22% increase was applied to the most likely per capita usage rate of 93 gpcd to establish the upper limit of per capita usage at 113 gpcd. For comparison, the per capita usage of the Northern Colorado NISP communities is 177 gpcd and the average per capita usage for Denver Water is 180 gpcd. The Town's per capita usage is not as high as these other communities due to the transient population (who use less water than the permanent population), the low occupancy rate of the permanent population 20 Water Conservation Plan (many households are second homes), and the absence of large irrigation demands. Table 3-4 provides a summary of per capita usage rates used in the 2007 Demand Projection. Table 3-4 Per Capita Demands Probability Per Capita Demand (gpcd) Low 73 Most Likely 93 High 113 The per capita deinands listed in the table above include all four categories of population (permanent, transient, wholesale, and non -transient). A more detailed analysis could be performed if per capita demands could be developed for each of these population categories, specifically permanent and transient since they represent the majority of the population. However, the permanent and transient populations can not be specifically associated with the residential and commercial usage (billing records) for several reasons including: A portion of the transient population stays in rental condos, which have residential meters • The permanent population has an impact on commercial usage, which cannot be separated from the impact of the transient population on commercial usage In general, the transient population will use less water than the permanent population primarily because a significant portion of the transient population is day visitors to Town and do not stay overnight. By applying the same per capita demand to both populations, we assumed that the ratio of permanent and transient populations will remain the same in the future. In reality, it is more likely that the growth rate of the transient population will outpace the growth rate of the permanent population. However, the demand projection will still be conservative (on the high side) since it is based on the ratio of the permanent population to the transient population in 2006 and this ratio is expected to increase in the future. 3.3 Buildout Conditions The buildout population of Estes Park was identified for each of the population categories discussed above. The buildout number for the permanent population was estimated using an extensive land use analysis. The buildout number for the transient population for the transient population was estimated using an analysis of growth trends in visitation to Rocky Mountain National Park. The buildout population of the wholesale population and the non -transient population could be reasonably estimated from the available data. These populations do not have much impact on the total water demand and therefore single point estimates were used with very little variability. The peak day demand at buildout was estimated by multiplying the total buildout population by the high per capita usage rate (113 gpcd) and the high peaking factor (2.0). Using the high values for both of these parameters helps to ensure that the Town will have capacity to handle unexpected demand, mainly due to drought, but also due to changes in people's water usage patterns. A 2.0 peaking factor occurred in the past (2002 and 2003). Three additional demands were included in the buildout peak day demand including the RMNP headquarters facilities, the emergency interconnect with the YMCA of the Rockies 21 Water Conservation Plan FIR (up to 0.43 mgd) and the emergency interconnect with the Prospect Mountain Water Company. The resulting peak day demand estimate at buildout is 7.9 mgd using the buildout condition assumptions established in the 2007 Demand Projection. Table 3-5 provides a summary of the calculation used for peak day demand at buildout. Table 3.-5 Summary of Peak Day Demand at Buildout Peak Season Population 2006 Additional at Buildout/% Total at Buildout Permanent 10,369 2,369 / 23% 12,738 Transient 10,789 7,592 / 70% 18,381 Wholesale Bulk 796 200 / 25% 996 Non -Transient 398 111 / 28% 509 Total Population 22,352 10,272 / 46% 32,624 Average Per Capita Usage during Peak Season (gpcd) 113 Peak/Avg Ratio in Peak Season (Peaking Factor) 2.0 Subtotal Peak Day Demand (ridg) 7.37 RMNP Headquarters Demand (mgd) 0.08 YMCA of the Rockies Emergency Interconnect (ingd) 0.43 Prospect Mountain Emergency Interconnect (mgd) 0.03 Water Treatment Plant Capacity Required at Buildout (mgd) 7.9 3.4 Potable Water Demand Projections The low, most likely, and high estimates developed in the previous sections of this report were incorporated into a Monte Carlo sitnulation. Monte Carlo simulation is a widely accepted risk assessment tool, which randomly samples from within the underlying distributions associated with demand parameters to generate a very large number of alternative combinations of these variables. The result is a joint frequency distribution for peak day demand consisting of 5,000 or more possible outcomes, with a probability associated with each. The following four steps were used to perform the analysis in the 2007 Demand Projection: 1. The 2006 peak season population was used as a starting point for each of the four population categories (permanent, transient, wholesale, and non -transient). The 2006 transient population was assigned a low, most likely, and high probability. All other population categories were not varied for 2006. 2. Low, most likely and high growth rates were assigned to each of the population categories. 3. The total population was multiplied by the average per capita demand in the peak season. The average per capita demand was assigned a low, most likely, and high value. 4. The average demand in the peak season from Step 4 was multiplied by a peaking factor. The peaking factor was assigned a low, most -likely, and high value. 22 Water Con Table 3-6 Summary of Parameters Used in Monte Carlo Simulation Parameter Low Most Likely High 2006 Permanent Population 10,369 10,369 10,369 2006 Transient Population 5,395 10,789 15,377 2006 Whole Sale Population 796 796 796 2006 Non -Transient Population 398 398 398 Permanent Population Growth Rate 1.4 2.6 4.0 Transient Population Growth Rate 1.1 3.5 6.6 Whole Sale Population Growth Rate 0.7 1.3 2.0 Non -Transient Population Growth Rate 1.4 2.6 4.0 Per Capita Demand (gal/day) 73 93 113 Peak Day Demand / Avg Day Demand in Peak.

Each curve represents a peak day demand condition with a percent probability that the demand in a given year will exceed that demand condition. For example, in 2015, there is 25 percent probability that the 4.9 mgd demand will be exceeded based on the assumptions of this analysis. 23 A 8 7 6 2 i O 0/p/v/ Coxu^/vo//on P/an Figure36 Peak Day Demand Projections Build out demand =7.9 IOGD 14, 01 . � Historic Peak 24 Water GOOSE) 111 ti011 Pia 11 The Most Likely Peak Day Demand curve represents an estimate of future demands with a 50 percent probability that the demands will be larger or smaller than the represented demand condition. In planning for plant expansion, decision makers typically do not use the most likely peak day demand because the risk of the demand being larger than planned is higher than is typically prudent. A more prudent planning curve is the 10 percent exceedance curve. Using the 10 percent curve for the Town, the current plant production capacity will not be exceeded until roughly 2020. However, the GWTP will require replacement prior to this date as previously discussed in this Conservation Plan. 3,5 Conclusion Based on this analysis, the projected peak day demand at buildout of the permanent population will be 7.9 mgd and the buildout population will be 32,664 (including all categories of population). The peak day demand projection is a planning number and reflects several critical assumptions. The first major assumption is that water demands must be met in drought conditions, which means that the buildout peak demand calculation is based on the high peaking factor typical of a drought year. The other major assumptions pertain to the uncertainty in per capita water usage and the future population estimate. The peak day demand projection at buildout is based on a high per capita usage, which is above the calculated average for the Town, but still much below the average per capita usage levels in areas where irrigation is prevalent and the transient population does not make up such a large percentage of the water users (e.g. Denver). If irrigation practices change, the per capita usage will change as well. Uncertainty in the buildout population is associated with the fact that more than half the peak season population is % transient and is thus not predictable in association with land use. HDR believes that 7.9 mgd represents a reliable planning level projection that will ensure the Town can provide sufficient water to customers in the future. Consequently, this buildout projection which was established by the 2007 Demand Projection will serve as the basis of planning for this Conservation Plan. 4,0 Profile Proposed Facilities 4.1 Identify and Cost Potential Facility Needs Through the Town's planning efforts over the past 10 years, a number of facility improvements and additions have been identified to replace aging infrastructure. The schedule for these improvements has been developed in a manner that allows for completion of plant improvements projects while still having potable water capacity to operate. The four major project areas included in the planning are detailed in this section. 4.1.1 MWTP Improvements MWTP improvements, which were completed in early 2011, brought the total plant capacity to 4 mgd by retrofitting the existing facility with 2-stage membrane treatment. The plant typically operates at or near 99% recovery, with waste flows of one percent of production being discharged to the wastewater system. Currently, the Town has a discharge limit of 20,000 gal/day, averaged over a month, to the sanitary sewer. This limitation effectively limits plant production to 2.2 mgd. The Upper Thompson Sanitation District (UTSD) fee structure is comprised of tap fees, discharge fees, and surcharge fees. UTSD does not have a commercial or industrial tap rate, so MWTP discharges are 25 Wa (..rr Con orFvation flan subject to the single family equivalent (SFE) tap fee of $8,700/SFE. Each SFE is equivalent to 200 gpd discharge. The current UTSD discharge fee is $6.25 per 1000 gallons of water discharged, with a surcharge for wastewater with TDS above 230 mg/L of $0.36/Ib. Based on these fees, the cost for the Town to purchase additional discharge capacity to increase the discharge limit to 40,000 gal/day would be $870,000 for the tap fees. If the taps were purchased by the town, the Marys Lake WTP production limit would be 4 mgd. Daily discharge fees for wastewater at 4 mgd plant flow rate would be $250/day. 4.1.2 GWTP Replacement The Town plan calls for replacing the existing GWTP conventional treatment plant with a two -stage membrane plant on the same site. The current plant can produce up to 3.6 mgd for very short periods of time, but typically operates at peak flows of 2.65 mgd during the summer season. Replacement plant infrastructure would be sized for eventual expansion to 4 mgd, with the initial investment in membrane equipment for 2.65 mgd. The plan for providing a 4 mgd plant at the Glacier Creek site is tied back to utilization of water rights at that location and to the desire on the part of the Town to be able to run either one of the two treatment plants during low flow production periods (typically winter), allowing for routine annual scheduled maintenance to take place with the plant off line. The proposed replacement for the GWTP is a two -stage submerged membrane plant similar to MWTP. The project will include pretreatment ahead of the membranes, along with waste tankage, chemical feed systems and storage, and a clearwell. Access road improvements will be required, along with electric service, fiber optic connection, and natural gas service upgrades. The site of the current plant creates some challenges, including piping of waste flows to the nearest sanitary sewer and the associated cost for sewer taps. Disposal of wastewater from the GWTP site to the sanitary sewer will require compliance with the same rate structure from UTSD as is in place at MWTP. Discharge capacity for the GWTP to meet 40,000 gal/day production levels will be $1.74M for tap fees and $250/day for discharge fees. The total 2010 order of magnitude cost estimate for replacing GWTP is $22,772,000 at a capacity of 2.65 mgd. The estimated cost to install additional membrane equipment to increase capacity from 2.65 mgd to 4 mgd is $3,000,000. 4.1.3 System Water Storage Improvements The Town operates 11 water storage tanks, including two treatment plant clearwells, which are distributed within seven different pressure zones. Analysis and evaluation of storage capacity in each pressure zone identified four zones that require additional storage to provide optimum flow equalization, fire flow, and standby volumes of water. These extra storage requirements are not related to increased demand, rather they are necessary to provide adequate storage and fire flow under current demand conditions. Order of magnitude costs for the proposed new tanks can be found in Appendix A. 4.1.4 Distribution System Improvements The Town has identified distribution system improvements that will upgrade several pipelines that have high velocities and headloss under current demand scenarios, including some upstream of PRV stations. The overall objective of these projects is to reduce the risk of failure in distribution system piping. Upgrades to or parallel PRV installations to existing Stations have been identified to increase flow 26 I/Vator Conservation Plan through them. These improvements are being scheduled into the capital improvement program for the utility over the coming years and are not tied solely to expanded water demand. Order of magnitude costs for the proposed system improvements can be found in Appendix A. 4.1.5 Improvements Schedule The Town has already completed the first major project that is part of the improvements plan, the renovation of MWTP to produce 4 mgd. As the Town moves forward to replace the GWTP, timing must be tied to both the demand projections and to the potential for required treatment improvements that may arise as a result of raw water quality testing under the Long -Term 2 Enhanced Surface Water Treatment Rule. Plant improvements are proposed to take place in accordance with Figure 4-1, where GWTP is taken off line for replacement in 2019, with completion at 2.65 mgd capacity by 2021. Prior to taking GWTP off line, the wastewater discharge capacity at MWTP must be adequate to allow the plant to produce 4 mgd as the Town must have capacity to survive on only one plant for a two-year period. (This could be accomplished either through third stage treatment or purchase of additional discharge capacity from UTSD.) Even with MWTP at 4 mgd capacity, additional temporary treatment may be necessary during the GWTP reconstruction period (or at least during peak summer demands). The Town cannot further delay the reconstruction of GWTP because the deficit in available treated water would be so large as to require extensive temporary treatment units, which would significantly increase the cost of construction. The timing for addition of capacity (from 2.65 mgd to 4 mgd) to the reconstructed GWTP may be delayed, depending on a revision of the demand projection in the future. 27 Water Conservation Plan liE Figure 4-1 Plant Improvements Schedule Coordinated with Demand Projections Q1lIieP MGO P I roe {4 MGO) MD) - ale Iefnana a toe.

The Town's situation can be defined as follows: • Peak day demand for the Town is driven by the influx of tourists arriving in the summer, not the permanent population. • Per capita water usage is relatively low given that there is negligible irrigation water usage and the number of tourists, who use significantly less water than a representative of the permanent population. • The projects identified in the Town's capital improvements plan (CIP) are not driven by the need for additional potable water capacity. • The Town has limited staff resources and funding for new conservation efforts. As a result of the issues defined above, the Conservation Plan Committee has established the following goals for the development of this Conservation Plan: 1. Reduce annual treated water volume production by 3% 2. Reduce the volume of waste discharged to sewer at MWTP 3. Review existing conservation measures/programs and decide whether to continue them 4. Provide definition for current utility practices that do not have formal plans or budgets, but that contribute to overall water conservation 29 VVirfor Gon°;eivaiion Plan HE 5. Provide a documented report of potential conservation measures/programs that could be implemented in the future, even if they are not selected for immediate implementation as part of this plan 6. Develop a Conservation Program that will be implemented by the Town following the completion of this plan 6.0 Identify Conservation Measures and Programs 6.1 Identify Conservation Measures and Programs The Conservation Plan Committee met on June 8, 2011 and September 28, 2011 to review potential conservation measures and programs. The list of conservation measures and programs that were considered for this Conservation Plan are listed below and a description of each follows. Demand -Side Measures (DM) • Water -Saving Fixtures • Town Irrigation System Improvements Supply -Side Measures (SM) • Third Stage Treatment • Bleeder Automation •rnPressure Zone Management • Reuse Demand Side Programs (DP) • Water Audits for Top Customers • Elementary Education Program • Drought Plans and Rates • Rate Structure by Meter Size • Time of Upgrade and Time of Sale • Multi -Family Residential Unit Metering • Town Website Supply -Side Programs (SP) • Customer Meter Testing and Replacement • Leak Detection and Repair • Tracking of Breaks and Repairs 6.1.1 Water -Saving Fixtures (DM) As previously mentioned in Section 2.6, the Town currently advertises and distributes "free water -saver kits" to its customers for free. The kits consist of a variety of water saving plumbing fixtures as sold by Niagara Conservation including: 1.5 gpm showerheads, toilet tank bladders, 1.5 gpm faucet aerators, 0.5 gpm faucet aerators, dye tablets (for toilet leak detection), and kits containing all of the items listed. This program has been in place now for 5 years and the Town will continue to utilize this program in the future as part of its conservation efforts. This includes distribution of the water saving fixtures at events 30 Water Corp3orvation Plan like "Sustainable Estes Park". 7 Wwvtt )fOgfaffi-IFfrey ,-6-Hd4t-s Hiffent-soeope-at-t-his-tiffie, fir -Wit ttiktitthmtig Ye r 4PNAN kil A i OIIL ttt l of ih k Formatted: Not Highlight diSttitylited kt re installed titimeowners and the Approximate water saviings florn each kit is fi.,900000 thefrqg aAYiNiM 111P Formatted: Not Highlight current cost of water of 50,.71pgr Lopo:aillons„jhe cost savings to the cattily for Formatted: Not Highlight 519cgLSAC, 0'2.421tre ha S:SL nftt ttltPitti_to cAlt.4110..111P.12.E121rottits ( Formatted: Not Highlight qtc•.t. Formatted: Not Highlight 6.1.2 Town Irrigation System Improvements (DM) Being a major tourist destination, the Town has a number of beautifully landscaped areas that are irrigated with treated water. The existing irrigation system controls are linked to the Town's SCADA, which allows Town staff to turn the system on/off from selected computers (i.e. staff do not have to manually turn the irrigation systems on/off at the individual landscaped locations). The existing system does not currently include the necessary software or hardware to automatically adjust watering amounts based on rainfall, temperature, etc. In order to provide this capability and improve the overall efficiency of the irrigation system, Town staff has proposed the following improvements to the irrigation system for evaluation as part of this conservation planning study: • Purchase and install wireless rainfall sensors • Perform water audits on all of the Town's irrigated water zones • Work with the Parks Department to upgrade the irrigation control system with IRRInet With the exception of the Town's irrigation system, there are limited opportunities for landscape efficiency measures within the Town. The vast majority of residents do not have turf lawns and/or landscaped areas due to the climate and the large population of elk that would destroy such vegetation. 6.1.3 Third Stage Treatment at MWTP (SM) Although the MWTP is rated for 4 mgd treatment capacity, the plant is somewhat handicapped by its sewer discharge limitations. Sewer discharge from MWTP is sent to the Upper Thompson Sanitation District (UTSD) wastewater plant and generally consists of waste from the second stage membranes, backwash waste from the raw water screens, waste from water quality analyzers, and sanitary waste. The Town has purchased sewer capacity and has an agreement in place with UTSD which allows for a sewer discharge of 20,000 gallons per day (calculated as an average daily discharge over a month). In addition to the base capacity that has already been purchased, the Town must also pay a discharge cost, which is currently set at $6.25 per 1,000 gallons of sewer discharge. On a continual basis, the MWTP can produce roughly 2.2 mgd and stay within the 20,000 gallon per day discharge limitation. In order to produce more than 2.2 mgd, additional sewer capacity must be purchased from UTSD at a cost of $8,700 per tap (I tap = 200 gallons per day of capacity). In addition, UTSD may implement a surcharge fee in the future if the waste exceeds UTSD's criteria for total 31 1/1/,1Pr.r l;orr.>orvasPion F'Lin suspended solids (TSS) and/or biological oxygen demand (BOD). Based on the water quality of the discharge at MWTP, the membrane waste flows can be expected to exceed UTS's TSS limit of 230 mg/L, but not the BOD limit of 230 mg/L. UTSD has notified the Town that the estimated surcharge fee for TSS is $0.36 per pound. UTSD tap fees and discharge fees are published on their website. By far, the major source of sewer discharge is backwash waste from the second stage membranes at MWTP. The most efficient means to decrease this waste volume is to install a third stage treatment process, which would result in a dry residual waste that could be hauled to a landfill. Using this approach, only sanitary waste would be discharged to the sewer. The Town evaluated technology alternatives for third stage treatment as part of their "Phase 2 Study, 2010, HDR". The results of that study indicated that membrane technology was the most viable choice for third stage treatment. At that time, the Siemens Memtek crossflow tubular membrane appeared to be the most promising product. Since that time, another membrane supplier, Inge, has entered the United States marketplace and indicated to HDR that they are also interested in a third stage treatment application. The current two - stage membrane system at MWTP has an overall system recovery of about 98%. Using third stage treatment, the system should be able to achieve about 99.9% recovery. 6.1.4 Bleeder Automation (SM) The Town currently has eleven (11) "bleeder" locations located throughout the distribution system where water is allowed to continuously run, primarily during the winter months. These bleeders are operated for freeze protection and are located on 2" distribution lines with shallow bury depths (< 3 feet). The Town has investigated an automatic flushing hydrant product that would allow some of the bleeders to be operated on a timed schedule in lieu of continuous operation. The Town has budgeted to purchase, install, and test several automatic flushing hydrants in 2012 to evaluate the potential water savings from this conservation measure. 6.1.5 Pressure Zone Management (SM) The Town has a significant vertical elevation profile across its service area. A number of pressure zones are required throughout the distribution system in order to maintain the appropriate pressures in each zone of the system. The pressures and zones are controlled by pressure reducing valves (PRV), which reduce the upstream pressure to a pre-set downstream pressure that is acceptable for that particular area of the system. One of the PRV suppliers, Cla-Val, now manufactures a PRV product that can automatically adjust pressure settings depending on system demand. During periods of low demand, the valve automatically adjusts to a lower pressure setting. This results in less water loss since customers will use less water (as a result of lower pressures) and existing leaks will experience less loss (also due to lower pressures). As part of this Conservation Plan, HDR performed a pressure zone management evaluation to assess the potential water savings from implementation of the automatic PRV's described above. Service Area 2 was selected for evaluation since it comprises about 73% of the total system demand and 63% of the total distribution pipe. Within Service Area 2, a total of 8 PRV's would be replaced with new automatic PRV's ranging in size from 2-inch through 8-inch. Using a water savings calculator program available from Cla-Val, the estimated annual water savings value for this system upgrade is $43,000. Additional information on the Cla-Val automatic PRV and the details of the analysis are included in Appendix C. Implementation of the automatic PRV's described above will change the distribution system dynamics such that various portions of Service Area 2 would experience fluctuating pressures on a daily basis 32 Wa tor Conservation Plan tiR (daytime demand versus nighttime demand and the associated pressure settings). Due to the age of the distribution piping in the Town, there is some concern that these pressure fluctuations could increase the frequency of pipe leaks and breaks, thereby decreasing the service life of the affected distribution piping. HDR did not explore this concept with Cla-Val, but agrees that it is a valid concern. Consequently, pressure zone management was not included in the list of final conservation measures/programs to be implemented by the Town as part of this Conservation Plan. However, due to the potential water and cost savings estimated using the analysis presented above, it is strongly recommended that the Town further investigate this conservation measure in the future.

This information is included in Appendix B. Being a tourist destination, a number of the Town's top water users are hotels. It may be advantageous to form a partnership between the Town and specific hotels to perform a water audit. There are companies that specialize in water audits of this nature including the Brendle Group located in Fort Collins. The audit process involves a site visit by a specialist who will take an inventory of the existing water using fixtures/equipment (both quantity and rates), estimate the water savings from upgrading to more efficient fixtures/equipment, estimate the costs of the upgrades, and provide a summary report. For a hotel, the audit would focus on the following fixtures/equipment: • Guest room domestic use (shower, toilets, faucet) • Restrooms in common areas • Laundry facilities (if located on site) • Food service equipment (ice machines, dishwashers, sinks, food steamers) • Pool and hot tub Based on the results of the water audit, it may be advantageous for the Town to offer a rebate program to the hotel as part of a fixture/equipment upgrade. HDR estimates the cost of a typical water audit to be roughly $1,000. However, actual estimates are available from the companies that perform this type of work including the Brendle Group.

Predictions are that all toilets will be low flow by 2040. The implementation of either voluntary or mandatory audits for hotels and the other large water customers in Town is a sensitive subject and must be well planned and executed in order to be successful for both the Town and the customers. Consequently, the implementation of a large customer audit program is beyond the scope of this plan and will not be further evaluated. However,lhis idea will be revisited duringlhe flext gp.date of the Conservation Plan. ()-Li Elementary Education Program (DP) One means to increase the distribution and implementation of the Town's Niagara water -saving fixtures is to implement an elementary education program for water conservation. However, given the Town's limited staff resources and the already challenged school curriculum, this program was not further evaluated. (.,).....Drought Plans and Rates (DP) Town staff is anticipating that the Colorado Water Conservation Board will require all water supply utilities within the State to develop and submit a "drought mitigation plan". Assuming that this requirement will be formalized in the future, the Town is giving consideration to developing a drought rate structure as part of their mitigation plan. The rate structure would establish various water cost rates for customers depending on pre -determined drought triggers with a goal of reducing water consumption through higher rates during times of drought. This measure was not further addressed as part of this Conservation Plan. _Pi) Modify Rate Structure by Meter Size (DP) The Town's most recent rate study was performed in 2010 (Water Cost of Service, HDR, December 2010). One of the recommendations from this study was to adjust the monthly water base rate per water meter size using the standard AWWA meter capacity weightings. In essence, this adjustment would result in larger monthly base rates for all customers based on meter size. Due to the poor economic conditions at the time, it was recommended that the monthly base rate increase be implemented over a 3 year period. This modification to the Town's rate structure was not approved by the Town Board and thus was not further evaluated for this Conservation Plan. However, it is recommended that rate modification by meter size be revisited in the future as part of the Town's next rate study. Modifying the rate structure by meter size will lead to conservation by putting pressure on commercial structures to incorporate water -saving fixtures in new construction and by the financial pressure of higher monthly water bills. 0, 1,1ft)1 'Time of Upgrade and Time of Sale (DP) This conservation measure requires customers to meet specific water usage criteria for various fixtures in their home/business in order to receive Building Department approval for upgrades or at the time of sale. If the existing fixtures in the home/business do not meet the water usage criteria, then the customer would be required to install new fixtures prior to proceeding with upgrades or sale. The Conservation 34 Water Conservation Plan FR Committee believed that the legal issues associated with this conservation measure would make it too difficult to implement and therefore this measure was not further evaluated. ri I 1 I I Multi -family Residential Unit Metering (DP) Town ordinance currently requires all new multi -family residential developments to provide individual water meters for each unit of the development. However, many of the existing multi -family residential customers utilize a common "association" meter in lieu of individual meters. A potential conservation measure that was considered would be to enact a new ordinance requiring these existing customers to install individual meters. However, the legal issues required to implement this ordinance would be too complicated and therefore this measure was not further evaluated. Town Website (DP) As previously mentioned, the Town's website currently contains a summary of the Town's 3-Stage Conservation Plan (see Section 2.5), a list of conservation tips, and an advertisement for a "free water - saver kit". The Town intends to maintain the conservation information on the website, but there are no plans to update the website at this time due to limited staff resources. I I io I I I Customer Meter Testing and Replacement (SP) All of the Town's water customers are metered and the Town maintains a database of individual meters in the system. The database includes meter size, serial number, and model. The database also includes "installation dates", however, it is unclear whether these dates have been updated as meters are replaced in the system. The Town is in the process of converting to a new accounting software and the issue of meter tracking will be revisited at that time. The Town has tested a number of 3/4" -2" meters in the recent past and found that the accuracy is generally within 2-5%. Having identified the top water consumers in the system (Appendix B), the Town is interested in testing the larger water meters (3" and 4") for overall accuracy sometime in the future. Town staff estimate that there are fewer than 5 of these larger meters in the system. The testing is performed by an outside agency and can be either performed in place or off -site. Either situation requires considerable coordination with the customer since most of these larger meters are on hotels, which cannot be out of service for a significant amount of time. At this time, the Town does not have a formal meter testing and replacement program in place. Furthermore, there is no dedicated budget within the utility for this task. Members of the Town's metering department have proposed the following program for impleinentation as part of this Conservation Plan: • Test all 3" and 4" meters in the system within the next 3 years • Replace 2" and larger meters every 5 years • Replace meters smaller than 2" every 10 years 35 VIlater Cori i ry tioi f'L'in Correction and calibration of inaccurate meters will not likely impact the actual amount of water used by the customer unless the meter is found to be grossly under -measuring the water usage (which is not likely based on the Town's previous experience checking water meter accuracy). h I I lO I I Leak Detection and Repair (SP) The Town does not currently have a written policy regarding distribution system leak detection and repair. However, they have conducted leak detection surveys in the past using contract services. The Town would like to have a formalized leak detection program and dedicated budget with the goal of checking the entire distribution system in the next five years. Town staff has proposed the following leak detection and repair program for implementation as part of this conservation planning study: • Allocate funds annually for one week of leak detection survey work. • Repair any Teaks identified through the survey work 6 1O Tracking of Breaks and Repairs (SP) Town staff has attempted to track major breaks and repairs on a system map located in their Maintenance Shop. Ideally, the Town would like to track breaks and repairs using the existing GIS system database in the future. Customer leaks are tracked by Town staff on an existing spreadsheet. The Town has a "leak" policy stating that leaks occurring on the customer's side of the water meter will be reimbursed 100% if the leak is defendable based on the customer's historic water usage. At this time, the Town does not have budget to dedicate existing or new staff to upgrading the GIS database for tracing breaks and repairs. However, this effort will be considered in future conservation efforts. 6.2 Develop and Define Screening Criteria The Conservation Plan Committee developed the following list of criteria to screen the conservation measures and programs described in the previous section: • Staff resources not available • Legal issues too complex • Other 6.3 Screen Conservation Measures and Programs Table 6-1 summarizes which conservation measures and programs were selected for implementation and which were ruled out based on the screening criteria defined above.

For the purposes of this report, these eight measures and programs were combined into a single program, which will hereinafter be referred to as the "Town's Conservation Program". The following sections will summarize the potential cost and water savings for each of the eight program components. 7.1 Capital and OM Costs Table 7-1 summarizes the capital and O&M costs estimated for each of the Town's Conservation Program components. Administration costs for each program component were not included in the estimate since it is assumed that the program will be administered by the Town's existing staff without significant impact to their existing workload. Similarly, labor costs were only included in the capital costs if the program component requires outside contractors to perform the labor. 37 INator Coo ;MefV7tir>rr (Flan Table 71 Estimated Capital and O&M Costs for Town's Conservation Program Water Conservation Measure/Program CAPITAL COSTS O&M COSTS Materials Labor Engineering Total Water Saving Fixtures") $1,500 Town Irrigation System t Improvements and Audit' $1,000 $7,000 $8,000 $200 Third Stage Treatment") $358,000 $150,000 $76,000 $584,000 $1,460 Bleeder Automation") $33,000 $33,000 $1,000 Town Website`5t Customer Meter Testing and Replacement(6) $1,000 Leak Detection and Repair'7) $16,000 Tracking of Breaks and Repairs° Notes: (1) The Town will continue the existing program, Estimated O&M cost is $1,500 every 5 years based on historic invoices for Niagara water -saving fixtures. (2) The estimated cost of new equipment for the irrigation system is $1,000 and the estimated cost of the audit is $7,000. Estimated O&M cost is $200 every year for replacement parts. (3) Estimated cost of treatment unit in 2010 was $268,000. Addition to treatment plant for housing equipment estimated at $90,000 for 30' x30' space. Labor for equipment installation estimated at $ I50,000. Engineering costs estimated at 15% of total project cost or $76,000. Assumed $0.10/1000 gallons treated through third stage membrane (power and cleaning chemicals) and a maximum total of 14.6 MG/year treated. (4) Material cost based on price quote from Ten Point Sales for a total of (11) Kupferle Foundry Company, Model #9800 Eclipse Automatic Flushing Devices. O&M costs estimated for purchase of replacement parts each year. (5) The existing conservation information on the Town's website will be maintained and it will not be expanded at this time. Therefore, this is a "no cost" item. (6) Estimated O&M cost is $1,000 per year based on hiring an outside contractor to test two (2) of the 3"-4" meters in the system every year. (7) Estimated O&M cost includes $6,000 per year for an outside contractor to perform leak detection services on a portion of the distribution system and $10,000 to repair any leaks identified in the process, (8) The Town will continue to track breaks and repairs using the existing distribution system maps located in the Water Shop. Therefore, this is a "no cost" item. 7.2 Potential Water Savings The total water savings potential of each program component was estimated based on an assumed life span of the program component and the estimated annual water savings. In general, the life span of the program component was linked to the expected life of the equipment installed. This was the case for the following program components: Town Irrigation System Improvements, Third Stage Treatment, and Bleeder Automation. For the Leak Detection and Repair Component, the estimated life span is the estimated number of years to check the entire distribution system for leaks. Table 7-2 summarizes the estimated annual water savings and total life span water savings for the program components. Note that 38 M/ator Goo SGerv,ation Plan rR these water savings estimates could only be made on four of the eight program components given the available information. Table 7•2 Estimated Water Savings From Town's Conservation Program Water Conservation Measure/Program Expected Life Span (Years) Annual Water Savings (Millions of Gal) Total Life Span Water Savings (Millions of Gal) Water Saving Fixtures") Town Irrigation System Improvements121 10 0.55 5.5 Third Stage Treatment'" 25 5.27 131.8 Bleeder Automation'' 10 10.5 105 Town Website15' Customer Meter Testing and Replacement(6) Leak Detection and Repair(7) 6 4.2 25.2 Tracking of Breaks and Repairs(8) Total 20.5 267 Notes: (1) Water savings was not estimated for this program given the limited distribution and inability to confine if/when the fixtures were installed and if they were installed in the Estes Park water distribution system. (2) The Town's irrigation system used approximately 5.5 million gallons of water in 2011. The estimated water savings from the irrigation system improvements is 10%, which yields an estimated annual water savings of 0.55 million gallons. (3) Total treated water production at MWTP in 2011 was 309.7 million gallons. The current 2-stage treatment process is 98% efficient, for a total waste volume of 6.2 million gallons. A third stage treatment process is assumed to be at least 85% efficient, which results in a net annual water savings of 5.27 MG. (4) The Town's eleven (I I) bleeder locations used approximately 10.6 million gallons during the 2010-20I 1 season. The estimated usage for the same (1 1) bleeders with the new automatic flushing devices installed is 0.1 million gallons (3 minutes per hour at 7 gpm now rate for 6 months), which yields an estimated annual water savings of 10.5 million gallons. (5) The potential water savings generated by posting conservation information on the Town's website cannot be estimated. (6) The verification of water meter accuracy is not expected to significantly impact overall water usage and therefore the potential water savings from this program was not estimated. (7) Based on past experience, the leak detection process will identify an average of 4 leaks per year. Each leak is assured to be flowing at 2 gpm continuously, which yields an estimated annual water savings of 4.2 million gallons. (8) The potential water savings generated by tracking breaks and repairs can be estimated after a few years of data is collected. 7.3 Cost Effectiveness In order to evaluate the cost effectiveness of each of the Town's Conservation Program components, it is necessary to estimate the cost to supply treated water to the Town. This type of estimate would generally include costs for all of the treated water system components including supply, treatment, and distribution. However, for the purposes of this study, only the cost of water supply and the cost of 39 Wolof ("or)zservatron Plan treatment were evaluated. Changes to the distribution system that may arise in the future when expansion of the GWTP is necessary are currently undefined because the location of potential growth inside the Town limits is unknown, so those future costs are not included. The cost of water supply only applies to the MWTP and covers a "carriage cost" and "power interruption cost" associated with the Town's water rights through the Bureau of Reclamation. The cost of treatment is comprised of the operation and maintenance costs at the Town's two water plants, which includes chemicals, power, and sewer discharge. The O&M costs do not include staff time because regardless of the number of gallons of water treated, the same equipment must be operated and maintained. No savings in staff time will be realized by conservation measures. Table 7-3 summarizes the cost components described above. Table 7-.3 Estimated Cost to supply Treated Water to Town Treated Water O&M Cost Item Cost per 1,000 Gallons of Treated Water Chemicals $0.33 Power $0.1 1 Sewer Discharge $0.048 Water Supply $0.28 Total $0.77 Notes: (1) Total treated water produced at GWTP and MWTP in 2011 was 537.43 million gallons. For the purposes of this evaluation, it is assumed that the Town will continue to operate the plants the same time periods during any given year. (2) Total chemical cost at GWTP and MWTP in 2011 was $178,000. (3) Total tx)wer cost for GWTP and MWTP in 2011 was $60,000. (4) Total sewer discharge cost at MWTP in 2011 was $26,000. GWTP does not have any costs associated with sewer discharge. The MWTP sewer discharge cost was divided by the total treated water production at both plants. (5) The cost of water supply at MWTP includes a "carriage cost" and "power interruption cost". The total water supply cost for MWTP in 2011 was $150,000. As shown in Table 7-3, the estimated cost to supply treated water to the Town is $0.77 per 1,000 gallons. To evaluate the cost effectiveness of the Town's Conservation Program components, this cost was compared to the cost to "save the water" using the various conservation efforts identified. The cost to save the water was estimated by dividing the net present value (NPV) of each program component by the total water savings generated over the life span of the program component. The NPV calculation includes both the initial capital cost as well as the operation and maintenance costs over the life span of the program (see Table 7-1), discounted at a 4% interest rate. A copy of the NPV calculations is provided in Appendix D. A "cost effectiveness" number was generated by subtracting the cost to save the water from the cost to treat the water, with a positive result indicating that the conservation effort is cost effective and a negative result indicating that the conservation effort is not cost effective. Table 7-4 summarizes the cost effectiveness calculations described above. These calculations were only performed on the program components where an estimate of the potential water savings was available. Note, the cost of Third Stage Treatment will be addressed using a different calculation since this conservation effort is related to 40 Water Conseivt ttfttt Plan the cost to discharge water to the sewer in addition to the cost to retreat the water at the plant after the third stage process.

(2) "Total Life Span Water Savings" from Table 7-2. (3) Cost to Save Water = "Total Project Cost NPV" / ("'Total Life Span Savings" x 1,000) (4) "Cost to Treat Water" from Table 7-3. (5) "Cost Effectiveness" = "Cost to Treat Water" - "Cost to Save Water". (6) The cost effectiveness of Third Stage Treatment is addressed in Table 7-5 since the primary cost factor is not the "cost to treat the water", but the "cost to discharge the water to sewer". (7) Water savings was not estimated for this program given the limited distribution and inability to confirm if/when the fixtures were installed and if they were installed in the Estes Park water distribution system. As shown in Table7-4, the total NPV of the Town's Conservation Program (with the exception of Third Stage Treatment) is approximately $ 140,000. Only one of the three program components evaluated appears to be cost effective, which is the Bleeder Automation. The Town Irrigation System Improvements and the Leak Detection and Repair components do not appear to be cost effective when compared to the cost of treating additional water required to replace the water losses that could potentially be saved by these two conservation efforts. As previously mentioned, the cost effectiveness of Third Stage Treatment must compare the cost to save the water through this conservation effort to the cost to discharge the same water to the sewer. Table 7-5 41 I/Vator tPlat iD: summarizes this calculation using the Town's contracted rate with the UTSD of $6.25 per 1,000 gallons discharged to the sewer.

The results of the Third Stage Treatment evaluation presented above reveal that this conservation effort is cost effective for the Town relative to the other program components with a potential savings of $0.87 per 1,000 gallons. The financial plan proposed in 2010 included a pilot -scale test of third stage treatment at the MWTP in 2013. Data collected from that pilot would be used to refine the costs and benefits of implementing full-scale third stage treatment in the future. In light of the reduced revenues from lower implemented rates, the timing of this project is being re-evaluated. 7.4 Summary of Benefits and Costs The previous sections generated a "cost effectiveness" value to help the Town evaluate the components of their selected Conservation Program. Only four of the eight components could be evaluated in this analysis since potential water savings estimates could not be generated for the remaining four components. Of the four components evaluated, two appear to be relatively cost effective, Third Stage Treatment and Bleeder Automation. The remaining two components, Town Irrigation System Improvements and Leak Detection and Repair, do not appear to be cost effective based on the assumptions used in this report. However, the cost effectiveness analysis presented herein does not address all the potential benefits that could be recognized from implementation of the program components. For example, the Town's distribution system contains a large percentage of "aged" pipe that is susceptible to catastrophic failure. Implementation of the Leak Detection and Repair program could identify a leak that would otherwise become a break in the future, resulting in costs to the Town that are much greater than the cost to implement the program as a safety -precaution. Although four of the program components could not be evaluated for cost effectiveness, the Town will still include these in their overall Conservation Program as they are believed to offer benefits that justify the cost (if any) of implementing the program component. In conclusion, the Town will move forward 42 0 Water Conservation Plan ED:( with the Conservation Program identified in this Section, which consists of the following eight components: • Water Saving Fixtures • Town Irrigation System Improvements • Third Stage Treatment • Bleeder Automation • Town Website • Customer Meter Testing and Replacement • Leak Detection and Repair • Tracking of Breaks and Repairs Where the Town could see financial benefit from implementation of the Conservation Program is the reduction of operation and maintenance costs. This cost was previously evaluated in Section 7.3 with the results producing an estimated treated water cost of $0.77 per 1,000 gallons. Using this cost and the estimated annual water savings from the Conservation Program (20.5 million gallons from Table 7-2), the estimated annual operations and maintenance cost savings is roughly $16,000. Interestingly enough, this cost savings roughly covers the estimated operations and maintenance costs associated with the Conservation Program itself, with the largest expenditure going towards the Leak Detection and Repair program (estimated O&M at $16,000 per year from Table 7-1). 8.0 Integrate Resources and Modify Forecasts 8,1 Revise Demand Forecast(s) Section 3.0 presented a demand forecast for the Town that is based on being able to reliably meet peak day demand. The Conservation Program that has been selected for implementation is not expected to change this demand forecast as the program components will have little to no impact on peak day demand. The Town's peak day demand is largely driven by the influx of tourists during the summer months and the program components identified will have little impact on the amount of water used by those tourists. For this reason, the demand forecast presented in Section 3.0 will not be revised as part of this current Conservation Program effort. The demand forecast will be re -visited in the future to refine the potable water demand projection. Since the last demand projection was develop, the housing market and economic downturn may have impacted future growth and the number of transient water users. In specific, the next demand projection effort should consider including the following: • Perform a more detailed analysis of buildout population that considers individual parcels, land use, zoning, steepness of terrain (i.e. location with respect to the blue line), and access to utilities as well as redevelopment of existing developed land and changes in zoning and land use. • Work towards reducing the number of land use categories to make them more consistent with zoning districts. For example, land area designated as Potential Future Development (primarily agricultural land) was not considered in the calculation of the buildout permanent population in 43 I/Ihrtar C;ort➢r+erva1tion I'I,ur this analysis, even though some of this land is zoned as residential. Better correlations between land use and zoning districts might avoid this issue. • Attach water demand (meters and billing records) to GIS zoning and land use data to allow for additional water demand analysis using land use information. • Gain a better understanding of RMNP visitor quantities and the likelihood of a cap on total visitors. One aspect of this evaluation would be to examine trends in National Park visitation as a whole and inquire about projections for future visitation to all National Parks. • Evaluate the impact of water conserving plumbing fixtures on future per capita usage. In communities where the residential water usage is dominated by indoor use, the impact of water conserving plumbing fixtures can be as much as an 18-20% reduction. • Consider the impacts to the Town land use categories of converting lodging properties to condos for tax purposes. • Work towards developing per capita demands for each category of population, primarily the permanent population and the transient population. There is some potential that implementation of the Town's Conservation Program could impact average day water demand over the course of the year. Table 8-1 summarizes the potential annual percent reduction in treated water volumes that could be recognized as a result of implementing the Conservation Program based on 2011 treated water production. 44 71 Water Conservation Plan Table 8-1 Estimated Percent Reduction in Annual Treated Water Volume Estimated Annual Water Savings front Town's Conservation Program (Millions of Gal)"' Total Treated Water Volume in 2011 (Millions of Galr Potential Percent Reduction in Annual Treated Water Volume following Implementation of Town's Conservation Program(3) 20.5 537.43 3.8% Notes: (I) Estimated Annual Water Savings from Table 7-2. (2) Treated water production at both MWTP and GWTP in 2011. (3) "Potential Percent Reduction" = ("Estimated Annual Water Savings...") / ("Total 'Freated Water Volume...") x 100 8.2 Identify Project Specific Savings Similar to the demand projection discussion above, the capital improvement projects that are currently included in the Town's capital improvement plan (CIP) are not driven by the need to provide additional treated water to the Town, but are instead driven by such things as the need to replace aging infrastructure (GWTP replacement project), correct existing system deficiencies (such as treated water storage volume and distribution piping), optimize the Town's water rights portfolio (water supply purchases), etc. Consequently, the implementation of the Town's Conservation Program will not delay the need to execute the CIP in the mariner which has been previously identified in the numerous planning studies and reports that have been prepared for the Town in the recent past (see Section 1.0 for a list of these reports and studies). 8.3 Revise Supply -Capacity Forecast(s) The only water supply related project currently included in the Town's CIP is the purchase of additional water rights for the GWTP, which will be executed in the next year or two. The purchase of these additional water rights is required to ensure that GWTP can meet existing peak day water demands should the MWTP be out of service. However, the purchase of these rights will also allow the Town to meet the projected peak day demand at buildout that was forecast as part of the demand projection in Section 3.0. Consequently, the implementation of the Town's Conservation Program will not impact the Town's current plans for water supply. 8.4 Consider Revenue Effects Implementation of the Town's Conservation Program is not expected to significantly impact revenue from treated water sales. The Town will be revisiting their overall rates and rate structure with an updated Financial Plan in 2013. The largest funding concern for the future is the GWTP replacement project, which as previously mentioned, will not be impacted by the implementation of the Town's Conservation Plan. 45 ,\ Ti Rsl to 60 day _Cmc revisit the Jr 2012.

For analysis purposes the following guideline can be used to select a number for N1. These N1 values are referenced from a system leakage analysis study. The user may want to enter different values for N1 if they are familiar with the leakage analysis method used and the proper coefficient value for their particular system. N1 = 1.5 is an average leakage coefficient value used for typical systems with undetectable background leakage with any pipe material. N1 = 1.0 is recommended if there is an abscence of knowledge of pipe materials and leakage level. N1 = 1.15 is ajapanese standard used for their systems for the past 20 years. N1 = 1.52 was an average value determined from lab tests by Ashcroft & Taylor (Surveyor, July 1983) on artificially created leaks in plastic pipe. N1 = 2.50 maximum recognized coefficient value for systems with excessive leakage. at (1/1icrtpia:bar Enter Model or Series number then click Search: Tc�chuticsv{ Hold OUTPUT DATA FOR SYSTEM LEAKS Average Flow Rate 1,023 Average Flow Velocity (approx.) 10.2 gpm fUsec Average Weekly Water Usage 10,311,840 gal Average Annual Water Usage 1,650 acre-ft Average Annual Water Usage 537.7 mg Estimated Daily Water Loss Based on Standard System Pressure & Estimated System Leakage Estimated Annual Water Loss 147,312 165.0 gal acre-ft Annual Financial Loss Due to Estimated System Leakage $220,990 PRESSURE MANAGEMENT OUTPUT DATA Estimated System Leakage at Standard System Pressure & Before Pressure Management Input Data 10.0 Calculated % of System Leakage Recovered with Pressure Management Input data 19.6 ova Average Daily Pressure with Pressure Management Input Data 122.0 psi Calculated Daily Water Savings with Pressure Management Input Data 28,815 gal Calculated Annual Water Savings with Pressure Management Input Data 32.3 acre-ft Calculated Annual Water Savings with Pressure Management Input Data 10.5 mg Calculated Annual Financial Savings with fdalrl dell Ial1 la Ill! all aalI Marl t:ontac:t'; http://www.cla-vat.com/watersavingscalculator.cfm 7/ 14/201. 1 Page 2 of 2 PMV Water Savings Calculator Jan 2008 Version 2REVB.xls Although some general theories reference upper coefficient values of 2.50, case studies associated with this value were not found.

The amounts returned to each utility were: Light & Power Department: $498,287 Water Department: $255,531 As these funds were an unexpected surprise, Trustee Blackhurst suggested they be used for projects not already planned. That suggestion brought an element of excitement to the brainstorming sessions. The two tables below represent the different projects considered by each department. Typical criteria for Water Department project selection include water system security, water quality and infrastructure improvements. The Town is in an admirable position in regard to water system security and water quality and we see no immediate needs for these areas. Six projects were listed for consideration and they are listed in order of their ranking by staff. Some of the typical criteria for Light & Power project selection include if the power line serves critical infrastructure, the power line proximity to a substation (largest number of customers affected by outage), and if an overhead line crosses multiple times over a collector roadway. For these funds we have included a project close to our public schools for addressing a more community -oriented project.
