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 81 miles of gravity sewers ranging in size from 6 inches to 27 inches in diameter together with nearly 4 miles of force mains, 7 pump stations, and over 1,500 manholes.


If you see water backing up in your sinks, shower, toilet or yard call CAWD immediately for a free inspection. Backups are an emergency so don’t hesitate to call us day or night. We are here to help you 24 hours a day, 365 days a year. Our friendly, professional staff will determine if the stoppage is in the main line (our problem) or the lateral line (your responsibility). If you call a plumber you will pay regardless of who is at fault.

Your yard’s sewer overflow device may look like a capped pipe or a mushroom. Keep it clear of soil and debris to prevent back-ups into your home. For help finding your clean-out / Sewer Relief Valve or for a free inspection please call us at (831) 624-1248.
