The San Diego County Water Authority is proactively fixing a 90-inch diameter pipeline in Bonsall as part of the agency’s long-term commitment to maintaining regional investments in water supply reliability and affordability. Water Authority staff detected potential pipeline weaknesses just north of West Lilac Road in late January using real-time acoustic fiber-optic monitoring. This technology locates distressed sections of pipelines even while they are in use as part of the Water Authority’s high-tech asset management program. Further investigation prompted the Water Authority to prioritize repairs on a 48-foot-long section of pipeline. Water Authority staff are carefully monitoring the pipe section around […]
The San Vicente Pipeline Tunnel, a key component of the San Diego County Water Authority’s $1.5 billion Emergency Storage Project, is now complete.

The San Diego County Water Authority completed construction of its Otay 14 Flow Control expansion project, preparing it for connection to a new 36-inch Otay Water District pipeline. When complete in summer 2010, the pipeline will double daily treated water deliveries to the Otay Water District to 16 million gallons per day. The flow control expansion project is a key component of the Water Authority’s East County Regional Treated Water Improvement Program (ECRTWIP).

The San Diego County Water Authority’s Board of Directors today approved a milestone project in the agency’s Pipeline Relining Program, authorizing the contract to rehabilitate more than four miles of large-diameter pipeline between Lake Murray and Sweetwater Reservoir. The $28.6 million project is part of the Water Authority’s multi-decade program to rehabilitate prestressed concrete cylinder pipeline (PCCP) within the Water Authority’s conveyance system with steel liners to extend their service life and ensure continued system reliability. When completed, the Water Authority will have rehabilitated approximately 45 miles of PCCP and passed the halfway point toward achieving the program’s overall goal […]
The San Diego County Water Authority continued to assess repairs needed on Pipeline 3, an untreated water pipeline that failed May 16 in Mission Trails Regional Park. The damaged pipeline was inspected internally, and several areas were excavated for an external visual inspection. A total of eight damaged pipe sections have been identified that need repair.
The San Diego County Water Authority is repairing a pipeline in a remote section of Mission Trails Regional Park after a section of it failed early Sunday just north of the San Diego River.
No injuries were reported and initial assessments indicate that property damage was limited to erosion in the park from the release of approximately 3 million gallons of untreated water from the pipeline, known as Pipeline 4, into the San Diego River. Water service to homes and business was not affected.
The San Diego County Water Authority's ongoing effort to diversify its water supply portfolio and ensure reliability took another step forward with the release of two draft environmental impact reports for public comment. The individual reports cover the Water Authority's Mission Trails Project in Mission Trails Regional Park east of Tierrasanta and the Regional Seawater Desalination Project at the Encina Power Station in Carlsbad. Each EIR will be available for public comment for 45 days.äóÂäóÂ
