It is expected that the consultant will make <br />effective use of available groundwater models such as those developed by the <br />State of Colorado or the U.S. Geological Survey as a basis for making these <br />projections. If the consultant feels that a different model is warranted then the <br />cost, justification and timeframe for developing that model will be presented to <br />the Study Group for its approval prior to commencing any work related to the use <br />of the groundwater model. The goal is to define the yield for all existing water <br />resources (both absolute and conditional) available to each Study Participants <br />without any regional cooperation in sharing individually developed water <br />resources or developing new transmountain diversion projects. <br /> <br />/ "' <br />( <br /> <br />Based upon the water demands estimated above and the results of the water <br />supplies analysis described above, the consultant will calculate the future water <br />shortage for each member, assuming that there is no further water supply <br />development by Study Participants. <br /> <br />The consultant will then work with individual Study Participants to identify and <br />analyze any future water supplies available to that member by the year 2050 from <br />groundwater, South Platte River water, non-potable reuse and conservation. The <br />Management Team will approve which of those identified future water supplies <br />will be considered for evaluation as part of the Study, The consultant will <br />conduct a feasibility analysis of the identified supply sources that could be <br />developed in the future to meet additional demands identified for each member. <br />This analysis will consist of any actions necessary to maintain the Firm or Safe <br />Yield of each source, including environmental and monetary costs. This analysis <br />will assume no regional cooperation among Study Participants on resource use or <br />development, no interaction with Denver Water or Aurora (or other public <br />utilities), and no development of new transmountain diversion projects. Lastly, <br />the consultant \vill compare and contrast each Study Participants' future water <br />needs with their future water supplies to identify any shortages. <br /> <br />( <br />\ <br /> <br />Task 1: Management Of Groundwater Resources - a feasibility analysis of methods to <br />regionally manage the available Denver Basin ground water for the benefit of Study <br />Participants. <br /> <br />A critical assessment of the opportunities to prioritize the use and distribution of the <br />available and recoverable Denver Basin groundwater resources available to Study <br />Participants is required. This assessment must consider the long term performance of the <br />aquifer system as a resource used for sustainable municipal purposes and should therefore <br />identify a reasonable management approach to its use through, as well as beyond, the year <br />2050, The assessment will consider all significant factors associated with the use of the <br />aquifer including, but not limited to, well production, water quality treatment and ( <br /> <br />dcwra scope of work 12/01/99 <br /> <br />4 <br />
