Sewer Jetting

Waconia's Utility Maintenance team is now jetting sanitary sewers. Jetting is a system that helps to clean the sewer by eliminating blockages. This is months-long process, and will typically wrap up in mid-fall. See the map below for the focus area for 2021. 

There should be no significant disruptions to the public during the jetting process, however during cleaning of sanitary sewer lines, air occasionally vents into a home through the 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 when cleaning sanitary sewer lines that have a steep slope
      - Sewer lines running close to a structure
      - A plugged roof vent
      - The size and complexity of the home’s waste and ventilation system 
To minimize water splashing out of your toilet bowl when crews are working in your neighborhood, make it a habit to keep the lid down.
