Cleaning and Televising
Saint Paul's sanitary sewer cleaning and televising (TV) program started in 2004 with a goal to clean and inspect approximately 80 miles of sanitary sewers including utility covers each year. This program helps to evaluate, clean, and repair sanitary sewer pipes on a regular schedule which minimizes unexpected problems and emergency repairs.
Sewers are cleaned using high velocity jet equipment, which is placed directly into the sewer through an upstream utility cover. The extreme pressure of the water removes the dirt, sand, rocks, and minor roots and pushes the debris to the downstream utility cover.
TV Inspection is done with a camera that is placed directly into the sewer through a utility cover.
