Pipeline 4 Repairs Underway In North San Diego County

A recently discovered leak in a section of a pipeline in North County will be repaired in coming months while Pipeline 4 returns to service.

Crews have installed bulkheads in the pipeline to isolate a portion of Pipeline 4 for repairs. This will allow the pipeline to continue treated water deliveries throughout the county in a modified fashion starting the week of Sept. 16 and restores full service to retail water agencies. With the leaky section isolated, crews will make necessary repairs.

Four Water Authority member agencies – Fallbrook PUD, Rainbow MWD, Valley Center MWD, and Vallecitos Water District – have taken steps to manage water supplies while the pipeline was shut down to install the bulkheads.
