The City of North St. Paul has a sanitary sewer-cleaning program that includes cleaning the sanitary sewers on a 3-year revolving schedule.
A sanitary sewer jet-cleaning machine uses high-pressure water to clean the sanitary sewer. This high water pressure may affect your home's sanitary sewer plumbing. You may experience gurgling or bubbling water in the toilet bowl or you may smell sewer gas from your basement floor drains. If this does occur, flush your toilet, close your toilet lid and pour water into your floor drains. This does not damage your sewer system. The water that comes out is the water that is normally in the home's system (drain traps), not the water from the sanitary sewer in the street. If your home is not properly plumed you may experience more splashing from your toilet bowl or a greater smell from your floor drains.
