SAVANNAH, GA (WTOC) - A grease blockage in a sanitary sewer gravity main is being blamed for a sewage spill on Tuesday, according to the city of Savannah.
The incident is classified as a major spill under Georgia's Environmental Protection Division guidelines, according to the city. City crews were notified at 7:45 p.m. Monday of a sewage smell and no overflow was found, but a grease blockage was found at 10:15 a.m. Tuesday. Crews then responded to the sewage that flowed underground into the storm main at Pennsylvania Avenue at Capital Street and it was fixed by 10:45 a.m. Tuesday.
The blockage was cleared, the storm main was flushed and cleaned and the storm main flows were contained and pumped back into the sanitary sewer collection system before entering the Kayton Canal.
Sampling is being conducted as required by EPD for major spills.
The Storm Pump Station at Kayton Canal was shut down to keep drainage water and sewage from reaching the Savannah River, according to the city.
A notice was posted about the spill at the nearest public landings on Hutchinson Island and at the Kayton Canal.
An investigation will be conducted to figure out where the grease blockage came from and repairs will be made to the subsurface defect in the sanitary sewer, according to the city.
