Sewer Connections & Backups Property owners own the sewer connection between private dwellings and the City’s sewer main system. Sewer backups are most often the responsibility of the property owner. The most common causes of sewer backups are invasive tree roots, improperly disposed of items, and maintenance issues due to age.
Sewer backups may be caused by clogs in the city's sewer system. The Wastewater Division can be contacted to check the city's sewer system for clogs. If it is determined that the problem is not in the city's system, a plumber will need to be contacted by the homeowner to investigate a clog in the private system.
To Report A Problem If there is no answer at the Wastewater Division, please call the general information number and leave a brief message stating your phone number first (example: "507-645-3052, sewer backup").
