Sewer Services

City sewage services are provided by the Metropolitan Regional Council through a large metropolitan network of pipes and lift stations owned and operated by the Metropolitan Council. Large sewer pipes, called interceptors, carry raw sewage to regional Metropolitan Treatment Plants where it is treated, processed and then returned to area lakes and rivers. The local treatment facility is located in Empire Township and treats sewage from Lakeville, Farmington, area townships and sections of Rosemount. Streets and utilities staff are responsible for inspecting, cleaning and maintaining the local collection system which includes pipes, manholes and lift stations.

Sewer backups happen

If you have ever experienced one, you know a lot of time and money is spent correcting the damage caused by the backup. Sewer backups caused by blockage due to debris or line breakage are cleaned and/or repaired as soon as possible. Tree roots and improper disposal of items such as grease, diapers, and rags typically cause sanitary sewer line blockages. City ordinance prohibits property owners from disposing of clear water into the sanitary sewer system, which can also cause backups. This includes water from any roof, surface or ground sump pump, foundation drain, or a swimming pool.
If a blockage occurs in the city’s main sewer line, the Municipal Services Department will take action to clear the blockage. The sewer line from a home, business, or other property to the city sewer main is the property owner’s responsibility.

If you experience a backup

  • Contact the city about emergency service requests during business hours at 651-280-6800 and after hours and weekends at 651-280-6700. The city will work with you to identify the location of the blockage.
  • If it is in an individual line to the property, the property owner will need to schedule and pay the cost of clearing any blockage. Many local plumbers provide this service.
  • Notify your insurance agent of the sewer backup to find out if such a claim is covered.
  • Clean the entire contaminated area safely and thoroughly or hire a reputable company experienced in cleaning up after sewer backups.
  • Document the actions you take (calls, contacts, costs) in response to the sewer backup. Many homeowners’ insurance policies exclude damage resulting from sewer backups.

If you are concerned about the possibility of a sewer backup, the city urges you to check with your home insurer regarding the availability of sewer backup insurance.

Sewer line maintenance

The city has 88.68 miles of sanitary sewer lines. The city is divided into nine sections and each section is cleaned and televised every seven seven years.  This routine maintenance helps to prevent sewer backups and to extend the life of the system. Lines requiring a higher level of maintenance are cleaned annually or semiannually.
