Discharge at Mapleton Wastewater Plant in Monona County
Posted: 05/27/2014

The city of Mapleton began discharging untreated wastewater into the Maple River Tuesday, after planned repairs on the wastewater treatment plant were delayed.


The city began routing wastewater to polishing ponds May 15, to enable repairs to a wall in the plant. The ponds filled to capacity Monday after heavy rains. The city began discharging wastewater to prevent damage to the ponds.


Contractors are expected to complete repairs by Wednesday or Thursday. The DNR cautions people to keep children and pets away from the area for 24 hours after repairs are completed.


The repairs were scheduled in April after a wall between two sections of the treatment system failed.
