If stream flows were too large to allow <br /> <br />installation of a temporary diversion, a low flow could most likely <br />be pumped without a diversion. <br /> <br />The berm may require regrading several times during the irrigation <br /> <br /> <br />season. However. the overall cost of such diversions is minimal. <br /> <br /> <br />The decision on the type and size of diversion will vary with each <br />parcel and would require extensive review in the field. Therefore, <br />in order to simplify the analysis it is assumed that no special <br />diversion structure will be required for parcels of 30 acres or less. <br /> <br />In cases where several parcels can be served from one diversion and <br /> <br /> <br />the combined acreage is over 30 acres. the cost of the diversion is <br /> <br /> <br />divided between the parcels in proportion to parcel acreage. This <br /> <br /> <br />approach is believed to be conservative (in favor of generating PIA) <br /> <br /> <br />and realistic for this type of analysis. <br /> <br />D.3.5 other Costs <br /> <br /> <br />Annual maintenance of major facilities including pipelines, pump <br /> <br /> <br />stations, and river diversions is estimated at 0.5 percent of the <br /> <br /> <br />initial construction cost. <br /> <br />The cost of electrical energy is assumed to be $0.068605/KWhr for the <br /> <br /> <br />southern Ute area and $0.065039/KWhr for the Mountain Ute area. <br /> <br /> <br />These are commercial user rates being charged during the first half <br /> <br /> <br />of 1985. A detailed discussion of the power costs was previously <br /> <br /> <br />provided. <br /> <br />7 <br />
