Project Description:

The work in this project consists of renovation of approximately 5,100 LF of sewer pipe by open-cut and pipe-bursting method.

Replace and rehabilitate approximately 5,100 feet of primarily 6-inch clay sewers with HDPE and PVC. Construct manholes, and other related work within city rights-of-way and private easements.

Three aerial sewer creek crossings will be replaced and work will be coordinated with the California Department of Fish and Wildlife and California Water Boards. Some of the existing sewers are deep (greater than 10 feet) and with manholes that reach 20 feet in depth. To minimize disruption and impacts to the neighborhoods, staff designed some of the sewers, to be replaced by a pilot tube guided boring (PTGB) method.
