Collection

The existing collection system is one of the oldest in the State with approximately half the manholes being the older brick type and most of the pipelines being of the old vitrified clay type. Deterioration of the mortar holding the manhole bricks together by gases produced in the sewer system and intrusion of roots into the joints of the older pipelines are the major reasons for replacement or rehabilitation.
The CAWD collection system is comprised of approximately 83 miles of gravity sewers ranging in size from 6 inches to 27 inches in diameter together with nearly 5 miles of force mains, 7 pump stations, and over 1,500 manholes.
