<br />to deliver up to 5 cubic feet per second (cfs) to save approximately 1250 acre-feet of <br />diversions from Castle Creek during the summer months. The project was estimated to have <br />a capital cost of $480 per acre-foot delivered and was among the more cost-competitive <br />water supply alternatives evaluated in the plan, <br /> <br />Since the analysis performed in the 1990 Water Management Plan, a second (private) golf <br />course has been constructed in proximity to the wastewater treatment plant. Although both <br />golf courses are presently supplied by raw water, the economics of using reclaimed water at <br />both sites would likely improve potential consideration of this project. Further evaluation <br />of economic feasibility also needs to consider potential wastewater treatment savings due to. <br />a reduction in effluent discharge to the Roaring Fork River. <br /> <br />Wastewater reclamation is not included in the five-year time span covered by the City's <br />Asset Management Plan. It will be further evaluated for both economic effectiveness and <br />to determine how a reclaimed water project would fit into water management policies. It <br />could potentially benefit in-stream flow conditions in Maroon and Castle Creeks below the <br />Herrick Ditch and Holden Ditch intakes, as well as the Roaring Fork River downstream to <br />. the wastewater treatment plant discharge. <br /> <br />e) Distribution System Leak Repair-- <br />The City of Aspen conducted a comprehensive system-wide leak detection analysis in 1994. <br />Results of the analysis are presented in Section 1.5. <br /> <br />In response to the findings of the leak survey, the City increased its annual budget for main <br />line repair and replacement from approximately $50,000 to $300,000 for a five-year period. <br />In order to respond to findings that the existing fire hydrants have a high rate of failure in <br />terms of leakage, it also budgeted $168,000 annually to replace the hydrants in the system <br />with this design flaw. <br /> <br />Leaking mains, hydrants and water service lines were estimated at 303 million gallons during <br />1994 (23 % of water deliveries). Considering the average losses in 1995, this figure is <br />estimated at 205 million gallons (16% of water deliveries). Since many of the leaks needing <br />- , , - - artenfi6n-wefefi6nepaiteauntn-the summet011995,-it IS estimated that repair work already - <br />performed in 1995 will bring the annual leakage rate down to I 02 million gallons (8 % of <br />water deliveries). <br /> <br />The overall goal.of increased funding for leak repairs, main line replacements and hydrant <br />replacements is to reduce the unaccounted-for use of water delivered to the system to 10- I 5% <br />over a five-year period. Note that meter errors and other system losses must be considered, <br />in addition to leaking mains, to determine if this goal is being met. Annual follow-up leak <br />survey work is conducted in areas where past problems have occurred or in new additions <br />to the system. The City will conduct a system-wide leak survey every four years, completing <br />a major quadrant each year, to update the results in order to guide expenditure of funds to <br /> <br />12 <br />
