OWOSSO — City officials said this week that more than 1 million gallons of untreated, diluted sewage spilled into the Shiawassee River because of heavy rain and high water.
“On Monday, the city began experiencing a sanitary sewer overflow at their waste water treatment plant,” city officials said in a press release. “The (sanitary sewer overflow) condition ended at 10:30 p.m. Monday.”
The Shiawassee County Health Department (SCHD) urged residents to avoid contact with the water in the river until further notice.
Two inches of rain fell at the wastewater treatment plant during a 90-minute period Monday morning.
Water samples for E. coli will be taken during the week of June 17 and the results will be available once received.
