In its continuing efforts to ensure a safe and reliable water supply for San Diego County, the San Diego County Water Authority will drain and inspect an untreated water pipeline in its Second Aqueduct from Nov. 9 to Nov. 18.
The shutdown of Pipeline 5 is part of the Water Authority’s regularly scheduled maintenance and Aqueduct Protection Program. The APP, established in 1992, is internationally recognized as the industry standard for large-diameter pipeline inspection and protection.
The APP allows the Water Authority to determine the nature and extent of corrosion problems along its aqueducts, assess pipeline conditions, complete necessary repairs to prevent pipeline failure and calculate the remaining life of its pipelines.
The shutdown of Pipeline 5 is part of the Water Authority’s long-range planning process. It is conducted in coordination and cooperation with its member agencies. Business and residential water customers will not be impacted by the shutdown.
Pipeline 5 provides untreated water to treatment plants in the Olivenhain, San Dieguito/Santa Fe, city of San Diego and Sweetwater Authority (National City/South Bay) water agencies. During the shutdown the agencies will use local water supplies held in reserve or will utilize treated water connections from the Water Authority.
The Water Authority operates a system of nearly 300 miles of pipelines providing both treated and untreated water to its member agencies in San Diego County.
The San Diego County Water Authority is a public agency serving the San Diego region as a wholesale supplier of water from the Colorado River and Northern California. The Water Authority works through its 23 member agencies to provide a safe, reliable water supply to support the region’s $126 billion economy and the quality of life of 3 million residents.
