The Columbus Water Works reported a sewage spill Tuesday on Fort Benning that ended up in Upatoi Creek.
The 15,614-gallon spill went into a an unmamed creek that feeds into Upatoi. It was caused by a line backed up by grease, Water Works spokesman Jim Patterson said Friday morning.
It is the second time in three weeks a blockage has occurred at that site.
It is at least the seventh major sewage spill Columbus Water Works has had to report to Georgia's Environmental Protection Division this spring. Most of the spills, which have been scattered across the county, have been caused by the heavy rains.
Never miss a local story.
All spills of 10,000 gallons or more have to be reported to the state, as do any spills that end up in state waters. The Water Works could face possible fines from the EPD.
