Cobb County’s Continuous Sewage Overflows Raise Environmental Concerns

Cobb County is facing growing environmental scrutiny from the community after the Cobb County Water System reported multiple sewage overflows in recent weeks—including one that released more than 52,000 gallons of wastewater into a local creek, resulting in confirmed fish kills.

The largest incident occurred on July 29 at 1973 Cobb Parkway NW in Kennesaw, where debris clogged a sewer line, releasing 52,080 gallons of sewage into a tributary of Noonday Creek. The overflow lasted more than three hours. No cleanup was reported, and dead fish were observed.

Other recent overflows:

• July 31 – 250 gallons at 22 Lakeshore Drive, Marietta (Sope Creek tributary); caused by debris.
• June 30 – 110 gallons at 2430 Powell Place, Kennesaw (Butler Creek tributary); caused by solids.
• June 27 – 90 gallons at 6247 Benbrooke Drive, Acworth (Little Allatoona Creek tributary); caused by roots.
• June 26 – 90 gallons at 2718 Long Lake Drive, Roswell (Willeo Creek tributary); caused by roots.
• June 24 – 70 gallons at 1016 Woodward Circle, Mableton (Clay Branch tributary); caused by rags.
• June 23 – 400 gallons at 4125 Lakeshore Way NE, Marietta (Sope Creek tributary); caused by debris.

In all incidents except July 29, cleanup crews responded by spreading lime. No additional fish kills were observed.

With repeated overflows affecting multiple watersheds, residents and environmental advocates are increasingly demanding stronger infrastructure maintenance and more proactive oversight. Many are now questioning the role of the Georgia Environmental Protection Division (EPD) and what enforcement measures are being taken as both the frequency and scale of spills appear to be increasing.
