CWA Approves Shutdown Schedule for Pipeline 5 Work at Moosa Creek

In 2019, the San Diego County Water Authority repaired a leak to a pipeline in Moosa Canyon. That repair was followed by an assessment of the other two SDCWA pipelines in the area, and one of those was found to be at risk so the CWA will be making repairs to that pipeline.

A CWA board vote, Feb. 27, authorized CWA general manager Sandra Kerl to take the necessary contracting and other actions for the repairs on Pipeline 5 in Moosa Creek. The current schedule includes shutdowns March 30 through April 5 for the installation of isolation bulkheads and May 18 to May 24 for the removal of the bulkheads as well as carbon fiber lining work expected April 6 through May 15.

May 24 is the Sunday of Memorial Day weekend, and the actual shutdown schedule will likely be revised as the repair work progresses.

CWA Ratifies Contracts for Moosa Canyon Pipeline Repair

The San Diego County Water Authority ratified two contracts for the repair of Pipeline 4 in Moosa Canyon. A unanimous CWA board vote Sept. 26 ratified a $950,000 contract with J.F. Shea Construction Inc. for the repair of Pipeline 4 and a contract for $871,342 with Fibrwrap Construction Services, Inc., for the carbon fiber relining of Pipeline 4. The action also authorized the continuation of the emergency declaration which exempts the CWA from the normal contract procurement process and from California Environmental Quality Act review.

CWA Pipeline Repairs Completed Under Budget

The San Diego County Water Authority repairs to Pipeline 5 were completed under budget. The SDCWA board approved a notice of completion July 25, which releases the remaining funds to the contractor. Although J.F. Shea Construction, Inc., bid the project at $25,304,375, the Walnut-based company was able to work with CWA staff to reduce the cost and the final cost of the work was $24,748,135.61. “The project was completed on time and within budget,” said CWA senior construction manager Gary Olvera. The CWA has an asset management program which uses both an acoustic fiberoptic monitoring system as well as internal inspections during aqueduct shutdowns to detect and monitor deterioration of CWA aqueduct facilities.
