The project replaces and constructs nearly three miles of two regional pressurized sewer pipelines (force mains) on Westminster Boulevard between Seal Beach Boulevard and Rancho Road/Hammon Place in the cities of Seal Beach and Westminster. Construction began Spring 2020 and is anticipated to be completed late 2022. Â
Intersection of Westminster Blvd. and Rancho Rd.Â
This portion of the work will rehabilitate the siphons, or pipelines, that go under the Barber City Channel at the Rancho Road intersection in the City of Westminster.  Temporary piping has been installed across the intersection to bypass, or reroute, flows out of the siphons.
Wastewater flows are bypassed out of the pipeline and the cured-in-place pipe method will be used for pipeline rehabilitation. A pre-measured liner is delivered in a refrigerated truck and inserted into the existing pipeline. Once the liner has been inserted, it is filled with water and cured for approximately 12 hours. When fully cured, the liner now acts as the new pipeline. Crews will be onsite for monitoring, including throughout the curing process.
Upcoming Activity:Â Pipeline rehabilitation using the cured-in-place pipe (CIPP) method
- When:Â Â Approximately starting the week of September 26 for a 1-2 week duration
- Work Hours:Â M – F, 7:30 a.m. – 4:30 p.m.**
- ** Around-the-clock monitoring will be required during the CIPP 12-hour curing process.
- Impacts:
- Traffic control will result in lane reductions and turn restrictions.
- Residents may notice an increase in activity and noise levels.
We understand that construction noise outside of normal work hours can be an inconvenience and we apologize in advance and thank you for your patience. We are working closely with the City of Westminster and have notified them of the schedule.
Between Bolsa Chica Rd. and Rancho Rd.
