At least 129,000 gallons of raw sewage spilled into local waterways in the wake of Mondays heavy rains, the Macon Water Authority reported to state officials Thursday.
Sewer pipes overflowed at three locations, the water authority told the state Environmental Protection Division, according to news releases from Heather Veal, the capacity, management, operation and maintenance coordinator for the authority.
The National Weather Service reported a total of 2.5 inches of rain fell in the area on Sunday and Monday, overloading the sewer system, Veal reported.
Around 2 p.m. Monday, an estimated 60,270 gallons or more of sewage spilled into Tobesofkee Creek from manholes in Flint Rock Park, 228 Gates Road.
The MWA is currently conducting a sewer main and manhole rehabilitation project in the Tobesofkee Basin which will help reduce the amounts of inflow and infiltration, Veal wrote. This project is scheduled to be completed in August of 2014.
The manholes that overflowed will be added to that project, she said.
From just before 2 p.m. until after 7:30 p.m. Monday, 16,614 gallons spilled at the Broadway lift station into a ditch feeding the Ocmulgee River. And 11 a.m. to 5:30 p.m. Monday, an estimated 52,125 gallons overflowed from around 2840 Pierce Drive S. into Bowman Branch, the water authority reported.
In all three cases, workers removed debris from the spill sites, disinfected the area with lime, and on Thursday began sampling water upstream and downstream, Veal said.
At the Pierce Drive South location, crews will check to make sure the pumps at the South Pierce lift station are working properly.
