<br />The City has a current finished water storage capacity of 17.5 million gallons, or <br />. approximately 5 days of average water demand on the system. <br /> <br />The Little Nell Well has a capacity of 1.5 MGD with current facilities in place. Plans for <br />expansion of wellfield pumping capacity to rehabilitate the Mill Street, Rio Grande, and <br />Anthony Wells are expected to expand the total groundwater pumping capacity (finished <br />water) to 4.1 MGD. <br /> <br />b) Raw Water-- <br />Raw water sources for the City, in addition to those supplying the Thomas Reservoir, include <br />the Wheeler/East Aspen Ditch (10 cfs); the Durant Mine Tunnel (2.8 cfs); the Si Johnson <br />Ditch (5.5 cfs); the Holden Ditch (30 cfs); the Marolt Ditch (18.6 cfs); and, the Hunter Creek <br />Flume (15 cfs). A portion of the diversions from the Castle Creek and Maroon Creek Flumes <br />is also used to feed raw water irrigation from Thomas Reservoir to the Meadowood Ditch <br />(02 cfs). <br /> <br />Other private users in the City's municipal service area have interests in ditch rights and use <br />raw water for irrigation. Current City policy requires the use of raw water in all new potable <br />water service whenever it is found to be feasible. Major private users (not under a City raw <br />water license agreement) of raw water include irrigation of the Maroon Creek Club Golf <br />Course, the Red Butte Cemetery, the Aspen Meadows and Institute, the U.S. Forest Service <br />Aspen District Lands, the Castle Creek Homeowners, and Red Mountain Ditch Company's <br />users located on Red Mountain. <br /> <br />2.2 Water Treatment Capacity <br />There are two treatment plants located on the Thomas property: the West Plant, which has a capacity <br />of 8 MGD; and, the East Plant, which has a capacity of 12 MGD. The combined capacity of the two <br />plants operating together is 20 MGD. The Hunter Creek treatment plant has a capacity of 0.5 MGD, <br />but is currently inoperable. The combined capacity to deliver treated water, including existing wells <br />and operable treatment plants, is 22 MGD. The peak hourly demand on record is 12 MGD. <br />Treatment plant capacity is not expected to be an issue in any of the water delivery scenarios <br />evaluated in (he 1994 RawWatecSupply AvaiJabiJityStudy.

The City Water <br />Department reviews all new construction and remodeling work requiring a building permit <br />in its water service area. It also conducts a walk-through of completed construction to verify <br />the number and type of fixtures in use. <br /> <br />10 <br />
