<br />, <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />Denver's existing water supply system and some of Denver's water rights. This <br />study will build upon effluent manag.ement and systems integration concepts <br />previously identified in the MWSI Project. Specifically, the study will focus on the <br />hydrology, water rights, operations, water quality and raw water storage aspects of <br />potential actions. <br /> <br />In the northwest geographic sub-region, a study will be conducted to define the <br />potential additional yield that could be cooperatively developed through <br />interconnections and cooperative use of storage facilities at one or more locations <br />in the northwest area. Northwest water supply systems, seasonal operations for <br />wetiaverage/dry years, participants' relevant water rights, and major system <br />facilities including diversion points, canals, pipelines, reservoirs, treatment plants, <br />principal treated water distribution lines and interconnections will be examined to <br />identify critical linkages, capacities and bottlenecks. An operational analyses will <br />be conducted to help identify constraints and opportunities. <br /> <br />In conclusion, it is important to note that investigation of opportunities for the use of <br />existing systems' infrastructure to promote maximum utilization of water resources <br />available to the South Platte Basin above the Henderson Gage requires a high <br />level of trust and cooperation between individual water providers and the State. <br />The identification and investigation of the opportunities listed above has occurred <br />as a direct result of the efforts of the members of the Technical Advisory <br />Committee for the MWSI Project. <br /> <br />Chaoter 7 - The Effect on Existing Water Rights of Current Recharge Technology <br />and Practices in the Denver Basin Aquifers (Technical Addendum No.1, Chapter 6) <br /> <br />Injection or recharge of reusable water into the Denver Basin aquifers for storage <br />and later recovery and use has significant potential for the Denver Basin aquifers. <br />Research by the Centennial Water and Sanitation District and the Willows Water <br />and Sanitation District has proven that this concept works at its existing storage <br />level, the Denver Basin has an estimated 500,000 acre feet of injection storage <br />capacity. <br /> <br />Impact on water rights would be minimal since the water used for recharge must be <br />fully reusable. Furthermore, the Denver Basin Artificial Recharge Extraction Rules <br />protect existing water rights in a number of ways. <br /> <br />Using excess water treatment capacity of water providers during the non-irrigation <br />season, water can be treated to drinking water standards and recharged using <br />gravity to inject water into the Denver Basin aquifers. This ability to use surplus <br />treatment capacity supports conjunctive use of surface water and ground water. <br /> <br />Chaoter 8 - The Impact of De Minimis Standards for Injury Based upon an Annual <br /> <br />-9- <br /> <br />.,. <br />
