Sewage spilled from a manhole in Norcross for nearly two hours Wednesday afternoon, the Gwinnett County Department of Water Resources said.
The spill at 4277 Windward Lane was first reported at 1:25 p.m. Department of Water Resources workers stopped the spill at 3:05 p.m.
By the time the flow was halted, 2,261 gallons had spilled onto the road, and some entered an unnamed tributary of Beaver Ruin Creek. Grease was the primary cause, with wipes, paper and other products as secondary causes, the department said.
The department raked the area and spread lime in order to mitigate the effects of the spill. Signs were posted to alert residents to the spill and the Georgia Environmental Protection Division was notified. Exposure to raw sewage generally poses the risk of diseases and infections including gastro-enteritis and E. coli.
