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.The Sewer Division is responsible for inspecting, cleaning and maintaining the local collection system which includes pipes, manholes and lift stations. Sewer backups caused by blockage due to debris or line breakage are cleaned and/or repaired as soon as possible.
