Protecting Our Most Valuable Resource, Water
Public Notification - July 9, 2026
Due to wet weather events and elevated wastewater flows, NEW Water initiated a partial bypass of treated effluent around the ultraviolet (UV) disinfection system at its De Pere Facility to protect facility operations and maintain continuous service to the community. The partial bypass occurred at approximately 8:15p.m. on July 8 and lasted about five hours. The bypass was discontinued once all flow could be safely managed through the disinfection process.
The Wisconsin Department of Natural Resources has been notified.
Responding to wet weather events requires additional operational actions in order to preserve equipment operation, and continuous service to the community.
During wet weather events, NEW Water facilities experience excessive flows from clear water getting into the sanitary sewer system. NEW Water is actively working with municipal partners to address this issue, learn more about Inflow & Infiltration here.
