<br />~ <br /> <br />The 68.1 acre-feet of water required for domestic consumption in the <br /> <br />month of July is the same as domestic and commercial water requirements for <br /> <br />all of the rest of the months when this is converted to cubic feet per second. <br /> <br />This conversion is 1.11 cfs, or 497.06 gallons per minute (GPM). <br /> <br />Should it be practical or feasible to any extent to ask the Eagle <br /> <br />Ranch Corporation to include two systems in their development, One for <br /> <br />domestic and commercial use and the other for irrigation, only 801.8 acre- <br /> <br />feet of water would have to be treated by the normal filtering processes. <br /> <br />If the total 1,468.5 acre-feet of water requirements would have to be treated <br /> <br />using a diatomaceous earth filtering system, the cost of the diatomaceous <br /> <br />earth alone would be approximately $34,000 per year. (This is based on the <br /> <br />cost of diatomaceous earth at $0.07 per thousand gallons.) The cost of <br /> <br />diatomaceous earth to filter water for domestic and commercial use alone <br /> <br />would amount to about $18,000 per year. This is a savings in the neighbor- <br /> <br />hood of $16,000 annually. It would appear prudent at this time to suggest <br /> <br />that the water for irrigation for proposed Eagle Ranch Corporation development <br /> <br />be provided from Brush Creek without the necessity of treating it. Along <br /> <br />this same line, it would also be practical to suggest that if the town could <br /> <br />construct a dual water system and treat only that water which would be used <br /> <br />for domestic consumption, there would be a large savings in operational costs. <br /> <br />It is estimated that the average household in Eagle would use only 10,000 <br /> <br />gallons per month for domestic use. Based on 421 taps the estimated consump- <br /> <br />tion for domestic use is 4,210,000 gallons of water yet the actual average <br /> <br />use per month is 7,020,000 gallons or an average excess of 2,810,000 gallons <br /> <br />used per month beyond what is normally required for domestic use. At a cost <br /> <br />of $0.07 per thousand for diatomaceous earth this could be a monthly savings <br /> <br />of approximately $195.00. However, this is not feasible due to the tradi- <br /> <br />tional and historic domestic water use of Eagle or of any older municipality. <br /> <br />. <br /> <br />~, <br /> <br />. <br /> <br />- 22 - <br />
