California River Aqueduct Pumping Plant Reliability Program - Circulation Water System Rehabilitation: Construction Project
Document Type
NOE - Notice of Exemption

Document Description
The Colorado River Aqueduct (CRA) is a 242-mile long conveyance system designed to transport water from Lake Havasu to Lake Mathews and includes five pumping plants. Cooling water circulates through the main CRA pump units to maintain their continuous operation. The circulation water system features strainers, which filter out debris and sediments from the cooling water to prevent clogging of the system. The existing strainers, valves and piping are original components with more than 50 years of continuous usage. Recent investigations identified degradation of the strainer components and deterioration of connecting piping. Metropolitan will perform installation and repair work for rehabilitation of the circulating water system.
