Sewer Line Cleaning

 

The District's sewer system contains about 320 miles of sewer lines. Keeping the sewer lines clean and free of obstruction is a very important part of maintaining the sewer system. If the lines are not cleaned regularly, debris or grease can build up inside the pipe and lead to an overflow into a basement or onto a street. Regular cleaning also helps catch any foreign material due to vandals or construction activity that could lead to an overflow. The District currently cleans its lines yearly, exceeding industry standards.

Lines are cleaned using high pressure water and a very large vacuum. Sometimes it is necessary for workers to enter the system to remove larger material. Crews are trained to enter confined spaces safely using air detectors and harnesses.
