The Shiawassee County Health Department (SCHD) said Wednesday morning it had been informed of a Sanitary Sewer Overflow (SSO) occurring at Durand the day before.
“On Tuesday, June 16, 2015, wastewater was discharged by the Durand Wastewater Treatment Plant into the Holly Drain north of the plant near Durand Road. Approximately 450,000 gallons of partially treated wastewater was discharged,” said SCHD Director Larry Johnson.
The Holly Drain flows into the Shiawassee River near Vernon (then through Corunna and Owosso enroute to Chesaning).
Additionally, an estimated 50,000 gallons of untreated wastewater was discharged from the Genesee Lift Station into Three Mile Creek, which also flows to the Holly Drain, then the Shiawassee River. A total rainfall of 2.39 inches was measured at the Durand Wastewater Treatment plant in 3.5 hours with 1.5 inches of rain falling in a 45-minute time period. “The wastewater overflows were a result of heavy rains that fell in a short period of time,” said Johnson. “The discharges only happen when heavy rains or excessive snow melt are experienced.
“SCHD advises that recreational users of the Shiawassee River avoid contact with the water until further notice.” The Shiawassee River was at flood stage Wednesday and minor flooding was occurring throughout Shiawassee County. People were advised to use caution when traveling in low-lying areas.
