Heavy rain on Sunday afternoon caused sewage to overflow out of a DeKalb County manhole, officials said.

The spill entered Shoal Creek off Melanie Court, according to a report from the DeKalb Watershed Management Department.

Almost 3,400 gallons of sewage was discharged, the department said.

It was initially described as a “major” spill, but a revised report Tuesday said the spill was minor and did not impact water quality.

It wasn't the only spill in metro Atlanta over the weekend; nearly 3,400 gallons of sewage spilled onto a Peachtree Corners street Saturday evening in Gwinett County, officials said.

Over the last several months, heavy rains have overwhelmed DeKalb County’s aging sewer system.
