City Sewer Maintenance

What is the City's sanitary sewer maintenance responsibility?

The City is responsible for maintaining the sanitary sewer pipes in the public Right-Of-Way (ROW) and ensuring access for private connections. In Minneapolis, most sanitary pipes run down the middle of the street.

How does Minneapolis inspect its sanitary sewers?

Sanitary sewer pipes, manholes and other system components are inspected by closed circuit TV once every 10 years. Emergency inspections are done as needed. 

How often are the sanitary sewers cleaned?

Sanitary sewer pipes are targeted to be cleaned every 8 to 24 months, depending on pipe size and method of cleaning. Emergency back-up calls are cleaned when crews respond to the emergency. Areas with a history of heavy root infestation or high levels of Fats, Oil & Grease (FOG) typically require a higher level of maintenance and are cleaned more frequently.

How does Minneapolis address Infiltration and Inflow problems in the sanitary sewer system?

Sewer Operations records cracks in sanitary sewer pipes that might contribute to Infiltration and Inflow (also known as I & I).

Is there information available on the cleaning frequency of a sewer pipe?

Sewer Maintenance has a scheduling system to provide historical information when sewer pipes were cleaned.

What is the City's responsibility regarding private sewer laterals?

The property owner is responsible that sewage can flow through their sanitary lateral (also called a sanitary service) to the sanitary sewer pipe. Please note that part of your sanitary lateral is in the Public ROW, but it extends all the way to the sanitary main. The sanitary lateral is the responsibility of the property owner.

When a failure or blockage of a private sanitary lateral occurs, Minneapolis Sewer Operations will verify that the sanitary pipe in the public ROW is operating properly. If the sanitary pipe is working properly, the property owner should call a licensed plumber or drain cleaning service to fix the problem with the sanitary lateral.

Contact the Sewer and Storm Drain Hotline at (612) 673-5625 if you have additional questions.
