Award of a contract to Yuma Rock and Sand, Yuma, Arizona, for construction of a concrete waste way structure as a key element in the Colorado River Indian Irrigation Project at Parker, Ariz., was announced today by the Department of the Interior.
Yuma Rock and Sand’s bid of $83,615 for the job was the lowest of five received by the Bureau of Indian Affairs. The other four ranged from $111,366 to $125,747.20.
The new structure will be located on the main canal of the project about 18 miles southwest of Parker and will replace a temporary timber structure installed about 14 years ago.
Plans call for extending the main canal about 27 miles to the south beyond the location of the new structure and for expanding the area under irrigation from the present 37,000 acres to an eventual 100,000 acres of fertile river bottom land. The new waste way, with a capacity of 1,500 cubic feet per second or three times that of the present structure, is designed to regulate the water in the main canal and to prevent flash floods and seepage and waterlogging of the area.
