Document Description
The Colorado River Aqueduct (CRA) is a 242-mile long conveyance system, which transports water from Lake Havasu to Lake Mathews. The CRA consists of five pumping plants, 124 miles of tunnel, 63 miles of concrete-lined canal, 55 miles of cut-and-cover conduit, inverted siphons, and reservoirs. The Metropolitan Water District of Southern California (Metropolitan) proposes to assess the existing power grid characteristics, the requirements for upgrading motor circuit breakers and related electrical equipment, and will conduct preliminary design to upgrade circuit breakers at the five CRA pumping plants. Additionally, Metropolitan proposes to evaluate alternatives for replacement of the disconnect switches at the CRA pumping plants' 230 kV and 69 kV switchyards, including the switch operators, and will perform preliminary design.
