Orleans, IA (KICD)–About 21,000 gallons of untreated wastewater discharged in Orleans Wednesday morning.
A resident reported an overflowing manhole in the 13700 block of Sunset Drive shortly before 8:00 a.m. The wastewater then flowed into the lake about 1400 feet northeast of the Orleans beach.
In less than an hour, the sanitary district stopped the discharge. The district discovered a pipeline below the manhole had collapsed. The district is working to repair the pipeline.
The DNR is taking water samples Wednesday for testing. DNR staff recommends residents stay away from the area of the discharge for 48 hours.
The DNR will continue to monitor the situation.
Storm Lake, IA (DNR)–A mechanical failure at a Tyson Fresh Meats wastewater lift station resulted in approximately 5,000 gallons of diluted wastewater reaching Storm Lake.
Tyson employees discovered wastewater coming out of the ground outside of the lift station Monday night after a joint on the piping failed. Upon discovering the discharge, the production plant was immediately shut down. Tyson worked with city officials to have most of the approximately 24,000 gallons that was bypassed diverted to Storm Lake’s sanitary sewer system.
The wastewater reached a storm sewer that eventually reaches the lake near Awaysis Beach. The city of Storm Lake has posted warnings there discouraging swimming until Friday when the normal beach monitoring results become available.
Water samples were taken from the lake at the outfall of the storm sewer and are being analyzed. The wastewater that reached the storm sewer was diluted by rainwater and groundwater already in the pipe as well as water used by the Storm Lake Fire Department to wash down the area where the bypass had occurred.
