Wastewater Treatment Plant Upgrade

Open House Invite:  Waupun Utilities will host an Open House on Wednesday, December 18, at 6:00 pm at the Utility Office at 817 S. Madison Street. The public is invited to attend to learn more about a planned Wastewater Treatment Plant (WWTP) improvement project and customer rate changes.

Open House Details: 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. 

Please join us at the Open House to learn more 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.
