MADISON, Wis. – The Wisconsin Department of Natural Resources today announced that it reissued the Wisconsin Pollutant Discharge Elimination System (WPDES) permit that regulates the treated wastewater discharged from the city of Waukesha’s Clean Water Plant.

The WPDES permit includes conditions and requirements for the discharge through the existing Fox (Illinois) River outfall and the proposed Root River outfall discharge location related to the Lake Michigan water diversion project. Discharge limits are included for pollutants with established water quality standards or discharge limitation guidelines. The permit does not regulate the construction or construction activities associated with the return flow pipeline or the specific route of the pipeline.

The reissued permit includes a schedule for the city of Waukesha to meet the final water quality-based discharge limit for total phosphorus at the Fox (IL) River outfall by June 30, 2022. Discharge limits for total phosphorus at the Root River outfall must be met immediately once the diversion is active. Year-round fecal coliform monitoring is also included for the Root River outfall. Finally, the permit includes requirements for monitoring and limitations associated with the land application of biosolids generated at the Clean Water Plant.
