Discharge Permit

In 2019, the District renewed its Wisconsin Pollutant Discharge Elimination System (WPDES) permit. Federal and Wisconsin law requires the District to have a discharge permit. The permit contains limits on what the District can discharge, monitoring and reporting requirements, and other provisions to protect public health and the environment.  As required by the permit, the District samples influent, effluent, overflows, groundwater, surface water, industrial facilities, and biosolids.
