~ - ~ N c. c _ 111m 2~'&;t},j.~":'f:~,',\. >;.- CAP construction completed to date includes two sections of the main aque- duct, eight pumping plants, various water distribution systems, and a headquarters building in north Phoenix, From this building, operators, assisted by computers, control the operation of the entire water conveyance system. One aqueduct, six pumping plants, one pump generating plant, some water distribution facilities, and a dam to provide regulatory water storage are, as yet, unfinished. The completed aqueducts, Hayden-Rhodes (formerly Granite Reef), Salt-Gila, and a portion of the Tucson Aqueduct are operational for 318 miles from the Colorado River to the San Xavier Pumping Plant on the Tucson Aqueduct. Water Aqueduct paving operation will be delivered to Tucson in 1991, and to the southern border of the San Xavier Indian Reservation in 1992, At one time, the Tucson Aqueduct was to end 33 miles north of Tucson and additional water for Tucson was to come from a reservoir impounded by the proposed Charleston Dam on the San Pedro River, Extending the aqueduct to Tucson and later to the boundary of the Indian reservation, lengthened the main aqueduct system from 300 to 336 miles. Electricity to operate the CAP originates at the Navajo Generating Station near Page, Arizona. The U.s, government is entitled to 24.3 percent of the output of the plant, which is the largest coal-fired, steam-electric generating station in the state. Built in 1970, the generating station has three units, each with a nominal output of 750,000 megawatts, The generating station's transmission system has two parts, the southern and the western, The CAP facilities are served by using a portion of both Navajo transmission systems, CAP funded new transmission systems, and contrac- tual arrangements with other federal transmission systems, The CAP's last major element, the New Waddell Dam, should be operational late in 1994, The dam is going up on the Agua Fria River about a mile south of the existing Waddell Dam, which is approximately 35 miles northwest of Phoenix. New Waddell Dam's reservoir will have water conservation space of 816,000 at includ- ing 658,400 af for CAP water regulation. New Waddell Dam is a partial substitute for Orme Dam, which was scheduled for construction at the confluence of the Salt and Verde rivers east of Phoenix. Along the course of the aqueducts are 43 turnouts through which water is - supplied to CAP customers' distribution systems, Sandario pumping plant motor installation New Magma Two and Two A turnout 13
