Cobb County Residents Alarmed After Another Sewage Overflow

Marietta, Ga. — Frustration and concern are growing among Cobb County residents after the Cobb County Water System reported a 220-gallon sewage overflow on November 29, raising questions about the safety and reliability of local infrastructure.

The spill occurred at 4870 Lake Fjord Pass NE in Marietta, releasing wastewater into the Timber Ridge Branch. Officials said the overflow, caused by a buildup of solids, was reported at 11:15 a.m. and stopped by 1:05 p.m. Crews spread lime to treat the area, and no fish kills were observed.

For nearby residents, however, such assurances offer little comfort. “This isn’t the first time we’ve had raw sewage spilling into our waterways,” said one resident. “We worry about our children playing outside, pets drinking water, and the long-term effects on our neighborhood streams.” Residents are being urged to contact Cobb County Commissioners and demand answers about the recurring sewage issues in the county.

Environmental experts warn that even relatively small spills can pose serious health risks, introducing bacteria, viruses, and other contaminants into local water systems. While county officials note that this overflow was contained, residents say repeated incidents highlight ongoing infrastructure vulnerabilities and maintenance concerns.

Community members are demanding greater transparency and action from the Cobb County Water System, including more frequent inspections, timely public alerts, and long-term investments to prevent future overflows.

The county encourages residents to report any sewage issues by contacting the Maintenance Division at 770-419-6393.

Still, for many, the question remains: how many overflows will it take before the system is truly safe?
