Sheboygan, Wisconsin – June 27, 2024 – The City of Sheboygan Department of Public Works reports that the Sheboygan Regional Wastewater Treatment Plant (WWTP) experienced an overflow of partially treated wastewater on Tuesday, June 25th, lasting approximately one hour. The incident occurred at three plant locations starting at 6:30 am.
The overflow was primarily caused by extreme weather conditions, with the area receiving 5 inches of rain over the preceding 72 hours, including 2 inches within a 2-hour period on the morning of the incident. This excessive rainfall, combined with ongoing construction at the plant, exceeded the WWTP’s physical hydraulic capacity.
While most of the overflow remained on plant grounds, some reached Lake Michigan and the southeast corner of Lakeview Park. As a precautionary measure, Lakeview Park was closed on Tuesday and Wednesday, with affected areas cordoned off. City staff conducted a thorough cleanup on Wednesday morning.
The City of Sheboygan urges residents to take the following proactive measures:
- Do not flush foreign items such as wipes, diapers, rags, and hygiene products into the sewer system.
- Ensure sump pumps discharge onto the ground or into storm sewers, not into sanitary sewer pipes.
These actions can significantly reduce the risk of future overflows and sewer backups.
WWTP staff promptly notified the Wisconsin Department of Natural Resources, water utility staff, City Administration, and the Mayor’s Office. The City Administration subsequently informed the City Attorney’s office and Common Council, ensuring a coordinated response.
“We take this incident very seriously and are committed to maintaining open communication with all relevant parties throughout the resolution process,” said Jordan Skiff, WWTP Superintendent. “We appreciate the public’s cooperation in helping prevent future occurrences.”
