The San Diego County Water Authority will drain and inspect two Second Aqueduct untreated water pipelines November 10 to 21 as part of its Aqueduct Protection Program.

The pipelines scheduled for inspection provide untreated water to treatment plants operated by City of San Diego and Sweetwater Authority (National City/Chula Vista/Bonita) water agencies. During the shut down the agencies will use local water supplies held in reserve. Business and residential water customers should not be impacted by the shut down.

The Water Authority operates a system of about 280 miles of pipelines that provide both treated and untreated water to the San Diego region. The shut down is part of the Authority’s long range planning and is conducted with interagency coordination and cooperation.

The Water Authority is recognized internationally for developing a systematic, proactive method to analyze and assess the life of the Water Authority’s pipelines. The Water Authority’s Aqueduct Protection Program is generally recognized as the industry standard for large diameter pipeline inspection and protection. It was established in 1992 to determine the nature and extent of corrosion problems along the aqueducts, perform condition assessments and calculate the remaining life of the pipeline.

The San Diego County Water Authority is a public agency serving the San Diego region as a wholesale supplier of water from Northern California and the Colorado River. The Water Authority works through its 23 member agencies to provide a safe, reliable water supply to almost three million county residents.
