Orange County Sanitation District (OCSD) – Sewer Project

Press Releases from the City

Los Alamitos Trunk Sewer 

Project Description: 
This project will make improvements to two parallel sewer lines along a two-mile stretch of Seal Beach Blvd/Los Alamitos Blvd. from just north of the I-405 freeway to Katella Avenue in the cities of Seal Beach and Los Alamitos. Also being repaired is the sewer on Katella Avenue from Oak Street to Lexington Drive. About 65 manholes will also be replaced or rehabilitated. The sewer lines suffer from corrosion and must be fixed to extend their service life. Once fully repaired, the lines will remain operational for another 50 years.

Any questions? Call the Project Hotline 800-274-3983.
