Upcoming Work
LOCATION: Airway Ave. between McCormick Ave. and Airport Loop Dr.
- What: Pipeline rehabilitation by lining the pipe using the cured-in-place pipe (CIPP) method. The work will occur in phased segments.
- When: During the week of April 1, and continuing the next several weeks with the next segments.
- Work Hours: CIPP activities will require 24/7 continuous work
- What to Expect:
- Traffic control will be set up around previously excavated pits
- Increase in activity and noise levels
- Smells from the curing process are anticipated to be minimal
As part of the CIPP process, OC San project contractors will be running water hoses into the local manholes near the construction site to discharge water from the project. Hoses will also be connected to fire hydrants for water. Some parking spaces may be coned off to route the hoses.
Current Work
LOCATION: Airport Loop Dr.
- What: Excavation of access pits located several hundred feet apart
- When: Ongoing and lasting approximately 2 months
- Work Hours: 7 a.m. – 7 p.m., Monday – Friday
- Impacts
- Travel lanes reconfigured with reduced street parking.
- Increased noise due to construction activity.
- A lane of travel in each direction will remain.
- Please drive with caution with the new street striping layout.
LOCATION: 3194 & 3199 Airport Loop Drive
- What: Cul-de-sac closure
- When: Current and lasting several months
- Impacts:
- No driving access to the end of the cul-de-sac
- Detours through the business complex may be necessary but access to businesses will always be available.

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).
