<br />Accordingly, City Council directed staff to propose a revised water rate structure to ensure that new <br />development outside the City, to be served under contract, provides for the same level of cost <br />recovery as attained for areas presently served. . Specific areas where revenue recovery through a <br />revised water rate structure needs to be addressed is for proposed service in the area southwest of <br />the City and for pumped water service to higher elevation areas surrounding the City. <br /> <br />1.8 Asset Management Plan (1995) <br />The City's Asset Management Plan (AMP) provides a blueprint for water-related capital projects <br />necessary to provide quality water service to existing and expected customers over a five-year period. <br />The AMP provided for improved funding to address excessive leakage in the water distribution <br />system and to improve the accuracy of metering for water usage. , The overall goal of these <br />expenditures was to reduce the overall gross unaccounted-for water to the range of 10 to 15%. <br /> <br />SECTION 2. INVENTORY <br /> <br />2.1 Water Supply Sources/Storage <br />a) Potable Water-- <br />Potable water sources for the City include Castle Creek, Maroon Creek and the municipal <br />wells. The Hunter Creek treatment facility is presently inactive, although the City has both <br />water rights and the physical capacity to supply water at this point. Raw water is conveyed <br />through the Castle and Maroon Creek Flumes to the Leonard Thomas Reservoir on the water <br />treatment plant site. The Thomas Reservoir has a nominal storage capacity of 10 to 15 acre- <br />feet, which is slightly more than the average daily demand on the water system. <br /> <br />The City provides water to approximately 2,400 accounts totaling 12,420 ECU's with an <br />average daily production of 3.4 MGD. Because a high percentage of these accounts is <br />attributable to multi-family residential structures, the actual number of residential units <br />served by the City is higher (approximately 7,600 units) than would be suggested by the <br />'number 6faccounts.- Metered water sales have- averaged 2.22' M6D over the past'twol'ears'. <br />An additional 330 ECU' s are provided service on a flat rate basis. Authorized, unmetered <br />uses--hydrant flushing, street cleaning, hydrant drafts, and unmetered accounts at parks-- <br />account for an additional 0.22 MOD. Identified losses (meter error, system leaks and <br />. reservoir overflows) account for .98 MGD. The current water production demand on an <br />'ECU basis is 97,300 gallons/yearlECU (0.3 acre-feet/yearIECU). At the point of sale to the <br />customer at the meter, the potable water demand is 65,250 gallons/yearlECU (0.2 acre- <br />feet/yearIECU). <br /> <br />The storage capacity of Thomas Reservoir is estimated as 3 to 5 million gallons (10 to 15 <br />acre-feet), which provides for raw water storage of 1 to 1.5 days of average water production. <br /> <br />9 <br />
