Yes, rainwater collection is legal in Georgia, but compliance hinges on local ordinances and intended use. State law permits non-potable rainwater harvesting without permits for residential use, though commercial or large-scale systems may require approval from the Georgia Environmental Protection Division (GA EPD). Municipalities like Atlanta and Savannah impose additional restrictions, particularly for potable systems.
Key Regulations for Rainwater Collection in Georgia
- Residential Non-Potable Use: Permitted under O.C.G.A. § 12-5-30 without permits, provided systems are designed for non-drinking purposes (e.g., irrigation, toilet flushing). Local health departments may inspect systems if contamination risks arise.
- Commercial or Potable Systems: Require GA EPD approval under the Water Quality Control Act, with mandatory treatment standards aligning with the 2026 EPA Lead and Copper Rule revisions. Systems serving >20 people trigger additional scrutiny.
- Local Ordinances: Cities like Atlanta mandate permits for storage tanks exceeding 500 gallons (Atlanta Code § 15-20.030). Savannah’s coastal zone restrictions limit tank placement to mitigate stormwater runoff impacts.
Additional Considerations:
- Stormwater Management: Systems must not exacerbate flooding or violate local stormwater management plans (e.g., Atlanta’s 2024 Stormwater Management Manual updates).
- Cross-Connection Risks: Backflow prevention devices are mandatory if rainwater connects to potable water systems, per GA EPD’s 2025 plumbing code amendments.
- Insurance & Liability: Homeowners should verify coverage with insurers, as improperly maintained systems may void policies.
