. . . Some water supply providers also rely on the renewable water resources of the Upper Black Squirrel Creek, within the Upper Black Squirrel Creek Designated Basin. Wh~le a comparison 1 of the water supplies available to these entities appears to meet year 2020 ~emands, water I levels have been declining over time in the Upper Black Squirrel Designated Basin. Based on studies that have been conducted to date, there are significant differences in the: expected useful life of the Upper Black Squirrel alluvial aquifer, but there is agreement that the water levels I are declining and that the alluvial aquifer is being mined at the current time. Therefore, there could be a future need for replacement water supplies in this area. : I I Water Conservation and Water Reuse I Water conservation and water reuse are two ways to maximize the efficiency of use of limited water resources. Water conservation can take the form of voluntary lin-house water conservation measures and voluntary landscaping irrigation measures, as wen as mandatory means to encourage water conservation, such as tiered pricing schedules and, Jltimately, water I rationing. Water reuse can take the form of indirect reuse, e.g. releasing wastewater treatment plant effluent, then producing an equivalent volume from the stream system, lor direct reuse, e.g. taking wastewater treatment plant effluent and applying it to irrigated areas. ! While in-house and landscaping water conservation measures can reduc~ overall water I consumption and help to reduce peak-day demands, the most effective watei, conservation is achieved through water pricing, i.e., where the price continues to rise with Jach incremental . I I I I I One of the benefits of Denver Basin aquifer water use is that this water cin be used, and reused, to extinction. An augmentation plan is the legal tool available in C610rado to allow water supply providers to reuse this water to meet municipal in-house ~nd landscaping I demands. Based on standard consumptive use factors, 100 ac-ft of first-us:e Denver Basin aquifer water can achieve, through multiple uses, an additional 86 ac-ft of water through an I augmentation plan. Therefore, augmentation plans and the reuse of water can be critically I important in achieving the most efficient use of this reusable water. i increase in use. County Water Distribution Infrastructure Options , I Because the water supply systems for the Northern Water Providers are distinctly different I than the water supply systems for the Southern Water Providers, water distribution I infrastructure options were evaluated separately for each water provider group': I I I 1 , , , I E-4
