Document Description
The project will rehabilitate approximately 21,045 feet of existing corroded 24- to 27-inch diameter non-reinforced concrete pipe (NRCP), vitrified clay pipe (VCP) and reinforced concrete pipe (RCP) on the Joint Outfall H Unit 9B Trunk Sewer with cured-in-place pipe liner and 39 manholes with a protective coating system. Lining was selected over replacement because replacing the sewer would be more disruptive and costly than lining.
