Wastewater Treatment Plant Upgrade

The WWTP is required to comply with new stringent phosphorus limits mandated by the U.S. Environmental Protection Agency and Wisconsin Department of Natural Resources by 2025.  The Utility’s engineering firm, Applied Technologies, determined the WWTP will be unable to meet the new level of effluent phosphorus limits with only operational improvements and minor facility modifications.   A study completed by Applied Technologies recommends the treatment process Advanced Biological Nutrient Recovery (ABNR) for Waupun’s WWTP to achieve compliance with its phosphorus limits in the Rock River Basin.  The ABNR system is an algae-based system capable of recovering phosphorus and nitrogen into harvested algae biomass. 

An open house was held at the Utility Office to the public on December 18, 2019. Valuable information was presented about the planned treatment process being implemented to meet the new phosphorus limits, along with information on the sewer rate increase required to pay for the improvements.
