<br />. <br /> <br />Hotchkiss replace the treated water transmission line from the water treatment <br />plant facility to the 0.4 MG clear water storage in three segments. By <br />phasing the replacement of the treated water transmission line in segments and <br />connecting to the existing system as construction proceeds, a continuous supply <br />of treated water may be delivered to the 0.4 MG clear water storage. The <br />first segment of the replacement of the treated water transmission line will be <br />from a point on the County Road designated as 3375 Road to the 0.4 MG clear <br />water storage. Segment 1 of Phase II will replace an old cast fron pfpe with <br />lead caulked joints and eliminate a major source of the leakage on the trans- <br />mission line. The second segment of Phase II will involve the replacement <br />of the transmission line from a point in the SW\ of the NW\ of Section 24, <br />T 14 S, R 93 W of the 6th P.M. to a point on the County Road designated as <br />3375 Road (between points Band C as shown on Exhibit A of this supplement). <br />The third segment of Phase II will be the remainder of the transmission line <br />from the treatment plant to the North end of segment 2 (from point C to point <br />D as shown on Exhibft A in this supplement). The construction of the first <br />segment of the replacement of the treated water transmission line will re- <br />quire 4,000 lineal feet of 10" pipe and funds for the Hotchkiss project will <br />be obtained from a loan from the Colorado Water Conservation Board. <br /> <br />Hydroelectric Power <br /> <br />On drawing No. 1 which was contained in the Water Supply Master Plan <br />Report the existing 8" raw water transmission line is shown and labeled. <br />At the approximate place where the existing 8" raw water transmission line <br />intersects the section line common the Sections 14 and 15, T 14 S, R 93 W <br />of the 6th P.M. to a point approximately 2,900 feet East, the raw water <br />transmission line drops 433 feet. The friction loss in this 2,900 lineal <br />feet of 8" transmission line is 10 feet leaving a residual head of 422 feet <br />(183 psi) which could be used for the generation of electrical power. <br />Exhibit B at the end of this supplement shows the existing 8" raw water <br />transmission line in plan and profile. The transmission line is open <br />to atmosphere at the top and bottom (points A and B as shown on Exhibit B) <br />and the installation of the hydroelectric plant at point B would not affect <br />the flow of water in the line. <br /> <br />Calculations have shown that the Town of Hotchkiss could expect to gen- <br />erate 28 Kw at point B. 28 Kw is sufficient electrical power to operate <br />all of the electrical appliances in the Hotchkiss water treatment plant with the <br />exception of a 40 horsepower backwash water pump. Power must be generated <br />at point B as shown on Exhibit B as the remainder of the raw water flow line <br />consists of an 18" low pressure flow line. Presently excess raw water spills <br />at point B as shown on Exhibit B in an existing gulch rather than spillover <br />the spillway of the 8 MG raw water storage reservoir. <br /> <br />In discussing the generating potential of the Hotchkiss raw water flow <br />line at point B, of Exhibit B with electrical engfneers, the Board of Trustees <br />of the Town of Hotchkiss, and the administrative staff of the Delta-Montrose <br />Electric Association it has been determined that a turbine large enough to <br />generate 15 Kw would be sufficient to operate all of the existing and the <br />proposed electrical appliances in the Hotchkiss water treatment plant, with <br />the exception of the 40 horsepower backwash water pump. Excess electricity <br />would not be sold to the Delta-Montrose Electric Association as the operation <br /> <br />2 <br />
