Sewer Rehabilitation and Replacement Project

(March 2016, South Pasadena) The City of South of Pasadena will commence construction of the Sewer Rehabilitation and Replacement Project Phase 2 in the next several weeks. This project is the second phase of a City-wide project to repair aging sanitary sewer lines.  This phase will repair approximately 20 miles of the City’s sewer system, primarily utilizing trenchless Cured-In-Place Pipe (CIPP) lining technology.  This trenchless construction technique consists of installing a flexible liner inside an existing sewer line, then heat curing it to create a hard 4mm plastic lining within the host pipe that will extend the life of the sewer pipe for another 50 years.  The CIPP lining improve reliability of the sewer system by addressing cracks, holes, obstructions and other deficiencies, which will reduce the occurrences of blockages and overflows.  Once the second phase is completed, approximately 60% of the City’s entire sewer system will have been rehabilitated over the last 5 years.

In order to improve the effectiveness of this major project, the Public Works Department is reminding residents that maintenance of the private sewer lateral running from the home to the City’s sewer main in the street is the responsibility of the property owner, and now would be a good time to do so.  Regularly maintaining the lateral by hiring a company to clean the lateral of roots, grease and debris, and to perform a video inspection of the lateral will ensure proper flow and will prevent backups into the home or business.

The contractor on this project will be Southwest Pipeline, inspection and construction 

management services will be provided by Valley Construction Management, and video and

cleaning will be provided by Ace Pipeline.  The project is  expected to last 15 months. 

Funding for this project is provided through a low-interest loan 
through the Clean Water State 

Revolving Fund.  Click here to view the map.
