About Cured-in-Place Pipe (CIPP)

A pre-measured liner is delivered in a refrigerated truck and inserted through a tall tower approximately 15 – 20 ft high into the existing pipeline through the recently excavated access pits.  After the liner has been inserted, it is filled with water heated to a certain temperature and cured for approximately 36 hours. When fully cured, the liner now acts as the new pipeline. Once the CIPP operation begins, it cannot be stopped until completed, thus requiring the 24/7 continuous work. Crews will be onsite for monitoring throughout the entire process.

Project Description

This project will rehabilitate two parallel regional sewer pipelines, along a 1-mile stretch on Airway Avenue and Airport Loop Drive in the City of Costa Mesa, near the John Wayne Airport. The rehabilitation of the two pipelines must occur one at a time and will take place in separate phases.

Project elements also include improvements at the Main Street Pump Station.  See map below (blue line).
