<br /> <br />2 <br /> <br />On the average, 20percent of the 2,579 Uncompahgre Project water subscribers <br />call for winter water; however, there are some who use it but do not call for <br />it. Therefore, assume 645 or 25 percent of the subscribers use winter water. <br /> <br />The winter water consumption per each of 645 subscribers per the 8-week billing <br />period is 30,000 gallons. Using the rate schedule, and assuming an average <br />current winter use of 10,000 gallons per 8-week billing period, the total cost <br />of delivering the winter water is $46,400/year, or a $630,000 one time cost. <br /> <br />System Extension Cost <br /> <br />The June 1981 consumption in the Tri-River system was 28.7 million gallons. The <br />average winter consumption is approximately 16 million gallons. Therefore, the <br />125 acre-feet or 10 million gallons per month would not strain the systems in <br />the winter. Another fact that is evident is that virtually all irrigation sub- <br />scribers are also on the treated system. Therefore, assume that the minor ex- <br />tensions to the system, additional taps, and other contingencies could be <br />handled with a ~ 25 percent contingency factor, or $200,000. <br /> <br />Association Overhead Expense <br /> <br />It is anticipated that the Uncompahgre Water Users Association cost of <br />administering the winter water replacement could be handled for 10 percent <br />of the above total or $100,000. <br /> <br />Winter Water Replacement Cost Summary <br /> <br />Raw Water Cost <br />Treated Water Delivery Cost <br />Contingencies + 25 percent <br />Subtotal <br /> <br />$/170,000 <br />630,000 <br />200,000 <br />$1,000,000 <br /> <br />Association Overhead 10 percent <br />Total (Jan. 81 prices) <br /> <br />100,000 <br />$1,100,000 <br /> <br />3-3 <br /> <br />OOlB61 <br />
