Infrastructure Projects
Metropolitan regularly monitors its water treatment and distribution infrastructures to assess their condition and ensure that critical facilities remain fit for service.  Each year, numerous capital improvement projects are implemented to improve the reliability of Metropolitan's water delivery system, including pipeline refurbishment and repair.  Although these projects may cause a short-term inconvenience in local communities, they protect ratepayers' investments in an $8.6 billion regional water system.

This page will post current projects in your area. It includes both capital projects and routine maintenance and inspection work.

Second Lower Feeder

The Second Lower Feeder is one of the major pipelines in the system. Approximately 28 miles of this pipeline needs to be relined with steel to ensure that it will be reliable long into the future. Currently, Metropolitan is relining 4.5 miles of the pipeline in the Cities of Carson and Los Angeles, and unincorporated areas in Los Angeles County.

Infrastructure Inspection and Maintenance

When necessary, Metropolitan temporarily takes parts of its delivery system out of service to conduct routine inspections and perform maintenance and upgrades with the least impact on consumers.
