The question about reliability extends beyond the <br /> <br /> <br />physical facilities to the safe yield of present water rights. Six alternative <br /> <br /> <br />water delivery systems were studied and an estimate of the safe water yield was <br /> <br /> <br />made. <br /> <br />Safe Yield Determination <br /> <br />The safe yield of a water supply system is the maximum amount of water that <br />can be delived, without interruption, throughout a critical time period. At <br />present, the safe yield of the District I s system will supply a population of <br />80,000 people. This figure is based on a maximum daily per capita demand of 248 <br />gallons. Under current population growth projections, the District I s service <br />population will reach this number in the year 2020. Consolidation of service <br />areas could alter this projection. <br /> <br />The recommendations regarding water supply are: <br /> <br />1. Long-range planning be continued for the development of additional <br />storage. <br /> <br />2. Acquisition of senior water rights be pursued on a case-by-case basis <br />when available. In Plateau Valley, these should be limited to the <br />first or second right on any given creek, <br /> <br />Alternative Water Delivery Systems <br /> <br />The following six alternatives to provide raw water to the District I s <br />treatment plant were studied. <br />
