Cypress Trunk Sewer
The Cypress Trunk Sewer Project is set to begin construction in July at the intersection of Moody St. and Crescent Ave. bordering the cities of Cypress and La Palma. Work will move south along Moody St. towards Orange Ave. in the City of Cypress.
This marks the first step in a major effort to improve the reliability and capacity of the regional sewer system in the cities of Cypress, Los Alamitos, and La Palma. The project will improve approximately 7 miles of sewer pipeline by either upsizing segments to increase capacity or rehabilitating them to extend their lifespan. More than 100 manholes will also be replaced or upgraded. Sign up for email and text alerts to get the latest news on this project.Â
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.
