Georgia liberalized its rainwater harvesting rules substantially under the 2010 Georgia Rainwater Harvesting Act, and unlike most states covered on this site, the technical requirements for a system are written directly into the state plumbing code.

RuleGeorgia
Source water Rooftop catchment
Permit required No, for typical residential barrels/cisterns; larger systems require a permit
Permitted uses Non-potable outdoor uses: irrigation, and per the plumbing code, fire protection; drinking water is not permitted
Reservoir standard Must be an approved, closed vessel built from durable, nonabsorbent, corrosion-resistant material
Filtration Water must pass through an approved filter system before distribution
Underlying statute Georgia Rainwater Harvesting Act (2010), codified in the Georgia State Minimum Standard Plumbing Code

Water rights: ordinary riparian rules, overshadowed by a genuine interstate war

Within Georgia, water rights follow the same general riparian reasonable-use framework common across the Southeast. But the legal story that actually matters for anyone relying on metro Atlanta’s water supply isn’t intrastate riparian law, it’s a three-decade interstate legal fight.

The Tri-State Water Wars, briefly

Since 1990, Georgia, Alabama, and Florida have litigated how much water Georgia can hold back in Lake Lanier and other reservoirs on the Apalachicola-Chattahoochee-Flint and Alabama-Coosa-Tallapoosa river systems, water Atlanta depends on for drinking supply, versus how much must flow downstream for Alabama’s and Florida’s own water needs, including endangered species protections in Florida’s Apalachicola Bay. As of recent rulings, litigation between the states in the ACF basin has paused for the first time since 1989, though related appeals remain active. This is not a settled, permanent resolution; the underlying tension between Atlanta’s growing water demand and downstream states’ needs hasn’t gone away.

Where to find it: the Georgia Environmental Protection Division (epd.georgia.gov) administers state water permitting; the Atlanta Regional Commission (atlantaregional.org) tracks the interstate dispute’s current status.

Permitless carry since 2022

Georgia is the fifth permitless-carry state covered on this site, joining Utah, Texas, Florida, and Ohio.

RequirementDetail
Standard Permitless ("constitutional") carry, concealed or open, since April 12, 2022 (Senate Bill 319)
Minimum age 21
Disqualifiers Any state or federal bar on firearm possession
Optional Georgia Weapons Carry License Still available and useful for reciprocity in states that require a permit from Georgia residents

Permitless doesn't mean unrestricted

Dropping the license requirement didn’t remove location restrictions. Carrying in a legally banned location, schools and certain government buildings among them, remains a criminal offense regardless of whether the carrier has a license.
