<br />26.5 <br /> <br /> <br />Fixed charge rates representative of municipal (6%) and private <br />(13%) rates were used. Costs are developed in a parametric fashion, using <br />1968 as the cost basis. Water costs are at the plant boundary, while power <br />costs include local transmission facilities. Both current and advanced <br />nuclear and fossil plant technology are assumed. Nuclear plants are of <br />~ the light water reactor (LWR) type. Desalting costs are based on both <br />ex> current technology and advances anticipated by 1985. Costs are allocated <br />~~ on the available energy basis. Cost results are shown in form of graphs <br />C) and charts by energy and water cost components. A procedure to determine <br />other water, power and process steam combinations utilizing the data developed <br />is shown. In addition to the generalized study, detailed costs are developed <br />for specific study cases of particular interest. The results of these cases <br />are shown in Appendix D. Energy costs developed on the parametric basis for <br />reference conditions are shown in Table 3-1. <br /> <br />TABLE 3-1 <br /> <br />SUMMARY OF POWER AND PROCESS STEAM COSTS <br /> <br />],/ 2:.1 <br />Plant Power <br /> .

This analysis indicates desalted water delivered <br />to the Salt Lake City distribution system would cost from about 20 to 33 cents <br />per 1000 gallon, or 63 to 108 dollars per acre-foot, depending upon the process <br />used and the character and source of the feed and blending water. <br /> <br />-7- <br /> <br />TABLE 3-1 <br />
