CSI - Fiberglass Manholes - Brochure

Concrete manholes are quickly becoming less common in new installations due to the increasing popularity of fi berglass. Sanitary sewer lines create an incredibly corrosive environment which causes leaks in concrete manholes and even worse, infi ltration. Infi ltration allows ground water to enter the waste line overburdening the system and increasing costs. Municipalities across the nation are investing billions in the rehabilitation of failing concrete manholes. Fiberglass manholes from Containment Solutions (CSI) are non-corrosive, watertight, and come with an industry leading 20-year warranty. Fiberglass is simply the superior choice for manholes.
