Orange County Feeder Relining Project
Document Type
MND - Mitigated Negative Declaration

Document Description
The proposed project would reline approximately 9.5 miles of the Orange County Feeder (OCF). The OCF pipeline is a welded steel pipeline, approximately 36 inches in diameter. It has bell-and-spigot joints and is lined with CTE to protect the inside of the pipeline. The CTE liner is blistering or peeling away from the internal steel face of the pipeline and exposing the pipeline to corrosion. The proposed project would remove the existing CTE liner, reline the pipeline with cement mortar lining, and install bonding bars between the pipe sections to enable the installation of an effective cathodic protection system for corrosion prevention. Maintenance and replacement of worn or outdated components (i.e. above-ground air release valves, vacuum valves) would also be completed as part of this project.
