~ pollution. Prior to 1970, the only source of treatment for water that Eagle had was chlorination. However, with the addition of the water treatment plant in the 1970-71 construction, the pollution from run-off from pastures should be an insignificant factor when determining a loca- tion for a point of diversion. With present day technology it is un- reasonable to assume that solid or organic matters in the water cannot be eliminated. A diversion dam and settling pond constructed approximately 14,000 feet upstream from the present treatment facility would create a static head of 230 feet. A 12" pipe carrying 1,380 GPM of water from this proposed source to the treatment plant would generate a pressure in excess of 52 psi at the plant. This pressure would be sufficient to operate the plant using gravity flow. A point of diversion 14,000 feet above the present water treat- ment facility would decrease the cost of the raw water flow line by 61 percent. However, the construction of a diversion dam, settling ponds, and other appurtenances would have to be added to this cost figure. The construction of a new diversion dam and settling ponds would have an advantage in that the design of these facilities would incorporate all the features presently lacking in the existing intake dam and settling ponds without spending money to remodel and make-do with the present intake facility. Any changes in a point of diversion from Brush Creek would have to be cleared through the water courts. But, then so would a change from a water right of irrigation use to one of domestic use. This could be done in a package presentation to the water courts. In other paragraphs in this report the need for an adequate water right has been dwelled upon. It would be recommended that if this alternate . ~. . - 42 -
