The city of Aitkin Public Works Department is now cleaning sanitary sewers.
During cleaning of the lines, air occasinally vents into a home through the sanitary sewer service line and ventilation system. When this happens, water in the toilet bowl can bubble or surge, or in rare cases, splash out of the bowl.
The common causes of air venting into homes during sanitary sewer cleaning are air movement from normal cleaning operations, the use of higher pressure necessary when cleaning lines that have a steep slope, sewer lines running close to a building, a plugged roof vent and the size and complexity of a home’s waste and ventilation system. So, to minimize water splashing out of your toilet bowl, make it a habit to keep the lid down.
