Contact 311

• If you have a sewer backup.
• If water is gushing out of a storm drain. In heavy rain, a storm drain may fill up and water pressure or trapped air can blow the manhole or storm drain cover off. Stay clear of the area until we've fixed it.
• If grass clippings or leaves are blocking a sewer. We'll send a Minneapolis Sewer Operations crew to clear the storm drain.
• For other non-urgent issues.

Causes of sanitary sewer backups

• Most backups occur when the sanitary lateral gets clogged with roots that have grown into a cracked or broken sanitary lateral.
• Backups may also be caused by:
  • A sanitary sewer pipe being in poor condition
  • Natural conditions, such as the ground moving
  • Higher than normal amounts of rain
  • Misuse of the sewer system in your home

After the cleanup of a sanitary sewer backup on your property

• Consider hiring a professional cleaning company to make sure no health hazards exist.
• The property owner can submit a claim for damages and other costs related to the back-up.
