Cobb County allows residential rainwater harvesting. No permit needed for rain barrels under 660 gallons. Cobb-Marietta Water Authority (CMWA) offers periodic rain-barrel workshops. Georgia Water Stewardship Act encourages harvesting.
Georgia law under the Water Stewardship Act of 2010 and the Georgia Plumbing Code specifically encourages residential rainwater harvesting for non-potable uses — landscape irrigation, vehicle washing, and toilet flushing (with appropriate plumbing). In Cobb County, rain barrels under 660 gallons (combined) at a single-family residence require no permit. Larger cistern systems, or any rainwater plumbed into the building's interior, require a plumbing permit from Cobb Community Development (770-528-2035) and must comply with Chapter 13 of the Georgia State Plumbing Code (cross-connection control, backflow preventer on any potable connection). Cobb County Water System and the Cobb-Marietta Water Authority periodically offer rain-barrel kit sales. HOAs in East Cobb and Vinings sometimes require rain barrels be screened from street view. Potable use of harvested water is not permitted without full treatment and health-department approval.
Large cistern without plumbing permit: $100–$500 Georgia Plumbing Code violation. Cross-connection to municipal supply without backflow preventer: mandatory disconnection + $500–$2,500.
