Cypress Trunk Sewer

Cypress Trunk Sewer

We are continuing preparation work for construction on the Cypress Trunk Sewer Project. This work marks the first step in major improvements to the regional sewer system throughout Cypress, La Palma, and Los Alamitos.

As early as July 23, crews will begin preparation and exploration work along the project alignment. This work involves carefully excavating holes to locate and verify underground utilities for safer and efficient construction, as well as accessing the manholes for upcoming rehabilitation work.

Here’s what you need to know about the upcoming work:

Location: Along the project alignment in Cypress, La Palma, and Los Alamitos (see map)

  • Crews will be at each location for 1-2 days
• Hours: Monday-Friday, 7:30 a.m. – 4:30 p.m.
• Impacts:
  • Reduced traffic lanes
  • Traffic control while work is being performed
  • Increase in activity and noise levels

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.
