Cypress Trunk Sewer

Cypress Trunk Sewer

Preparation work for the Cypress Trunk Sewer Project continues as part of major improvements to the regional sewer system throughout Cypress, La Palma, and Los Alamitos.

For the next few weeks, potholing and exploratory work will be done along the project alignment. This work involves carefully excavating holes to locate and verify underground utilities, as well as accessing manholes for upcoming rehabilitation work. After this work is complete, pipeline cleaning, grouting, and manhole rehabilitation will take place.

Project Description:

The regional sewer line in the cities of Cypress, Los Alamitos, and La Palma is approximately 50 years old and in need of upgrades. The Cypress Trunk Sewer Project will focus on enhancing about 7 miles of sewer, replacing portions of the pipe with larger diameter pipe to increase the capacity, or rehabilitating other segments of pipe to extend the life of the sewer system. Approximately 100 manholes will also be replaced and/or rehabilitated. These repairs will extend the life of the sewer pipes by another 50 years.

Schedule:
Construction is anticipated to begin in Summer 2025 and last approximately 3 years.
