Sanitary Sewer Utility

Sanitary Sewer Utility
The city is responsible for inspecting and maintaining the collection system infrastructure to ensure adequate and ongoing collection. 

The city has almost 63 miles of sanitary sewer line, 30 lift stations, and 987 manholes. Most of these lines run under the street. The Utility Department cleans large sections of the city's sanitary sewer lines each year. This routine maintenance helps to prevent blockages and backups. 

The Environmental Services Division of the Metropolitan Council (MCES) serves the city for sanitary sewer disposal. The City of Mound's wastewater is treated at the Shakopee Blue Lake Water Resource Recovery Facility. 

Private Sanitary Sewer Lines
Beyond the public sanitary sewer lines, there is approximately 60 miles more of private lines on private property. These lines are maintained by private property owners. 

Inflow and Infiltration (I/I)
Inflow and infiltration (I/I) is clear water - stormwater and groundwater - that enters into the sanitary sewer system. It can overload the system and can cause costly sewer backups into homes and buildings. 

Up to 80% of I/I comes from private sources, including defective sewer service lines and improperly connected sump pumps, downspouts, and foundation drains. Excessive I/I increases the need to build larger and more expensive sewer pipes and treatment plants. You can help reduce I/I! Visit the Metropolitan Council website for more information. 

Sewer Backups 
If you suspect you have a sewer backup, and you suspect it could be the city's sanitary sewer main, please contact the Public Works Department. 

Note: The city is not responsible for problems in buildings/homes for the private sewer line between the property and the city sanitary sewer main. For more information on private sanitary sewer lines backups and sewer line backup prevention recommendations, click HERE.
