Show another pipeline from Deer Creek Reservoir to Little Cottonwood Treatment Plant and beyond to the Metropolitan Water District's terminal reservoirs at 3300 South and Wasatch Boulevard. Alternatives within this study include several reservoir sites within Provo Canyon as well as diverting from Union Aqueduct if the Olmsted Powerplant were to be acquired. This plan would have greater costs and impacts on the environment from the pipeline, dams, and reservoirs along the Salt Lake Aqueduct and in Provo Canyon than the Jordan Aqueduct would Reservoirs within the canyon would inundate popular stream fisheries and parks and would require relocation of highway, railroad, water- lines, powerlines, and camping, and recreation areas through a 5- mile section of the canyon. ( d-) Additional Capacity Available in Salt Lake Aqueduct The Salt Lake Aqueduct was constructed with a design capacity of 150 c. f. s. to deliver water from Deer Creek Reservoir to Salt Lake City. During the summer of 1966, the aqueduct was tested to determine its actual capacity. It was determined that the aqueduct was capable of safely carrying 175 c. f. s. Operations of the Salt Lake Aqueduct are now based on this capacity. The Jordan Aqueduct is being constructed to specifications which will allow it to be operated in conjunction with the increased capacity of the Salt Lake Aqueduct. ( e) Alternative Locations along West Side Several alternative locations for the Jordan Aqueduct along the west side of the Salt Lake Valley were considered. They included a route traversing north along 1300 West, 2200 West, or 3200 West and a far west route traversing contours on essentially the hydraulic gradient. The 1300 West and 2200 West routes presented problems of street disruption along a narrow highway right- of- way and problems associated with detouring traffic, as well as coping with sewerline and waterline crossings. The 3200 West route had fewer problems of disruption of . existing facilities, a convenient hydraulic operating head, and a desirable distribution location, and is on a direct line to the existing tank farm at 6200 South and 3200 West. It was estimated that the 3200 West route would cost $ 2 million less 626 |
