Construction Notice: Pipeline 5 Relining 

A construction notice for the Pipeline 5 Relining San Luis Rey Canyon Project by the San Diego County Water Authority.

San Luis Rey Canyon Project from SDCWA

Project Overview

The San Diego County Water Authority is relining approximately 1.7 miles of Pipeline 5 in Fallbrook, west of Interstate 15. The project will not impact any Rainbow Water District supplies or services.

New steel liners will be inserted into the existing pipeline, which will prevent breaks or failures and extend the service life of the pipeline by 75 years or more. To minimize impacts, the relining will take place through seven access portals. 

Construction is planned to take place in Fall 2024, with completion targeted in Fall 2025. The majority of work is planned to take place Monday through Friday between the hours of 7 a.m. and 7 p.m. However, night work will occur for limited periods in November 2024 and again in late-April/early-May 2025.
