<br />5~Su <br /> <br />Pumping Plant No. 4 will be located in the north half of Section 36, <br />Township 15 South, Range 66 West. There will be a forebay tank <br />approximately 90 feet in diameter and 25 feet above ground. The <br />pumping plant intake manifold will feed two banks of pumps on <br />separate discharge manifolds. One hank will have a total dynamic <br />head of approximately 255 feet to serve Colorado Springs and <br />Stratmoor Hills, and the other bank to serve the Fountain-Widefield- <br />Security lateral will have a total dynamic head of approximately <br />195 feet. A separate air chamber will be located on each discharge <br />line at Pumping Plant No.4. The location of the terminal storage tank <br />for Colorado Springs is in the southeast quarter of Section 4, <br />Township 15 South, Range 66 West. The height of this tank will be <br />approximately 45 feet and the diameter will be approximately 100 feet. <br /> <br />. <br /> <br />A regulating tank 50 feet high and 40 feet in diameter along with <br />the Fountain-Widefield terminal tanks will be located in the north- <br />east quarter of Section 20, Township 15 South, Range 65 West. <br />The Security flow control station and terminal tank will be fed by <br />gravity and will be located in the northwest quarter of Section 12, <br />Township 15 South, Range 66 West. The Widefield, Fountain, and <br />Security terminal tanks will be approximately 100 feet in diameter. <br />The height of the Widefield and Security tanks will be about 40 <br />feet above ground. The height of the Fountain tank will be approxi- <br />mately 50 feet above ground. <br /> <br />Pumping plants and other structures will he designed to be compatible ~ <br />with the surrounding areas. <br /> <br />Blowoffs will be required at low points and air valves will be <br />required at high points in the pipeline. <br /> <br />Provision for reverse flow in the conduit will be designed at the <br />terminal tank for Colorado Springs and at Pumping Plant No.4. This <br />design will provide for a maximum reverse flow of approximately 8 ft3/s <br />from the Colorado Springs system to the lateral. The reverse flow can <br />be used for an emergency water supply to Fountain, Widefield, and <br />Security in the event of a temporary failure of any part of the conduit <br />up to Pumping Plant No.4 or the water treatment facility. <br /> <br />A power supply and substation will be required at each pumping <br />plant. The source of power has not been established at this time. <br />The assumption to date has been that the power for pumping plants 1 and <br />2 would be obtained from Southern Colorado Power. Power for pumping <br />plants 3 and 4 will probably be obtained from Colorado Springs. <br />Power provided will be by overhead service lines tied from existing <br />transmission lines including the l15-kV line that parallels the <br />conduit. <br /> <br />A control cable will be buried adjacent to the pipe in the conduit <br />right-of-way to allow remote control of the pumping plant. The <br />control center will be located at the purification plant. <br /> <br />. <br /> <br />11-5 <br />
