Pipeline 5 Relining San Luis Rey Canyon

Project Background

Project Map

The San Diego County Water Authority is planning on relining approximately 1.7 miles of Pipeline 5 in the community of Fallbrook, west of Interstate 15. The project is part of the Water Authority’s commitment to maintaining the critical infrastructure that supplies safe and reliable water to customers throughout the San Diego region. 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 access portals.
