Title: Lower Hetch-Hetchy Sewer Rehabilitation Project
Description: The proposed project includes the rehabilitation of approximately one mile of existing trunk sewer through the Cured-in-Place Pipe method. The CIPP involves using existing manholes to insert into the deteriorated pipe a resin-filled flexible tube that lines the sewer line by inversion. Water pressure is used to propel the inverting tube through the pipe and then hot water or steam is circulated through the fully inverted tube whereby the resin is cured and a new pipe is formed.
