Project Info

Title
Orange County Feeder Relining Project
Description
The proposed project involves relining approximately 9.5 miles of the OCF. The OCF is a welded steel pipeline, approximately 36 inches in diameter, and is lined with coal tar enamel (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 includes removal of the existing CTE liner, relining the pipeline with cement mortar, and installing 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 Maintenance and replacement of worn or outdated components (e.g. above-ground air release valves, vacuum valves) would also be completed as part of this project.
