FOR IMMEDIATE RELEASE:


A sanitary sewer overflow occurred at a manhole belonging to the Walworth County

Metropolitan Sewerage District’s collection system on the east side of South Shore Drive, approximately 750 feet south of Hwy 50 in the Town of Delavan. The manhole conveys wastewater from multiple communities to the pump station located at 2215 South Shore Drive. The overflow occurred from approximately 7:05 AM on September 8, 2021, to 11:15 AM on September 8, 2021.


A programmable logic controller failed resulting in loss of operation of the pumps in the station. Wastewater filled the wet well and surcharged the gravity sewer main until the pressure forced the wastewater out of the manhole. An estimated 146,750 gallons of untreated wastewater was released onto the ground and flowed to a nearby drainage ditch which flows to Delavan Lake. WalCoMet personnel responded to the incident, stopped the leak, cleaned the area of any debris, and continues to monitor the situation.


All necessary steps were taken to limit any public health hazard or potential harmful impacts to the environment. The Wisconsin Department of Natural Resources has been notified. Pursuant to the requirement in NR 210, this press release is being issued regarding this event.
