Metropolitan Council responding to wastewater spill in Mahtomedi

The Metropolitan Council, operator of the regional wastewater collection and treatment system, responded Wednesday morning, September 13, to an air relief valve malfunction and resulting wastewater spill at the intersection of Dunbar Way and Lincolntown Avenue in Mahtomedi. 

Crews from the Metropolitan Council’s Environmental Services division were able to stop the spill 45 minutes after being notified of the issue. Flow was redirected to a redundant pipe and crews were able to begin cleanup efforts and repairs to the faulty equipment. Water quality crews are preparing to test surface water in the two stormwater ponds. Signage will warn the public “Do Not Enter/ Sewage Spill” around affected areas.

An early estimate of 1500 gallons of wastewater was released from the pipe. Much of it was contained and staff are working to assess the volume that made its way into the storm drain and the two storm water ponds encompassed by Dunbar Way, Lincolntown Avenue, Kilbirnie Way, and Berwick Lane.

Find updates at starting Thursday, September 14. If you have questions, please contact our General Inquiries line at Metropolitan Council Environmental Services at or 651-602-1269.
