<br />Project Description <br /> <br />e <br /> <br />The purpose of this project is to provide a means for the Silt Water Conservancy District <br />to continue providing irrigation water to shareholders while minimizing the occurrence of future <br />disruptions of water flow, These alternatives were considered, <br /> <br />1, Continue with the existing management. <br />2, To replace the current inadequate diversion with new technology, <br /> <br />Alternative No.1 would involve maintaining the existing diversion. This would include <br />continuing to rebuild it annually, This alternative was eliminated due to cost, and because it did <br />not provide a permanent solution to the problem, <br /> <br />The selected alternative, Alternative No.2, involves the construction of a new diversion <br />approximately 1,000 feet upstream from the existing diversion, The water will be transferred in <br />940 feet of 42" HDPE low head irrigation pipe carrying 40 cubic feet of irrigation water to the <br />original ditch system, <br /> <br />Engineering designs and cost estimates for the project have been prepared by the NRCS, <br />Preliminary plans as prepared by the NRCS are attached in the back pocket of this study. <br /> <br />The NRCS estimates the costs of the completed project at $164,400.00, The NRCS cost <br />breakdown for the project is given below in Table 2, Operation and maintenance costs for this <br />project are expected to be minimal over the next thirty years, <br /> <br />. <br /> <br />Table 2.
