The Metropolitan Water District of Southern California

​The Metropolitan Water District of Southern California owns and maintains the regional water system that provides Southern California with imported water supplies.  We work closely with our 26 member public agencies to deliver this water day in and day out for drinking and groundwater recharge for the 19 million people they serve. Metropolitan continually monitors the condition of our Colorado River Aqueduct, pumping plants, 5 treatment plants, and 830 miles of pipelines so that repairs and rehabilitation projects can be completed as needed.  Reliability is a core part of our mission.

About the Project

The Second Lower Feeder is one of the major pipelines in the system.  Constructed in 1967, it delivers treated water from the Robert B. Diemer Water Treatment Plant in Yorba Linda to the Palos Verdes Reservoir in Rolling Hills Estates.  Approximately 28 miles of this pipeline need to be relined with steel to ensure that it will be reliable long into the future. The construction will be done in phases over a period of 8 to 10 years. Read our project fact sheet.  See a video clip about this project.

Neighborhood Alerts

Phase 2 continues in the city of Long Beach along E. Keynote St., and E. Conant St. We’re making progress and construction is on schedule.

Being A Good Neighbor

​Metropolitan is committed to working with local communities as we move through this project. We will continue to communicate prior to and during the work so that residents  can plan accordingly.

We worked closely with our member agencies to prepare for taking portions of this key pipeline out of service during construction.  The water supply to homes  will not be affected.

A community meeting was held in February 2019 to inform the public about key dates, construction and traffic impacts.
