Johns Creek, GA Landscaping Rules: Rainwater Harvesting (2026)

No Johns Creek city ordinance prohibits or restricts the collection of rainwater, and Georgia does not ban rainwater harvesting. The state encourages reuse: under Georgia's Water Stewardship Act, the outdoor-watering time restrictions "do not apply to the use of any water obtained from private wells, or from reuse water sources such as cooling system condensate, storm water, gray water and reclaimed wastewater." Georgia EPD likewise lists "capture and reuse of stormwater" among uses allowed at any time. This means a Johns Creek homeowner using a rain barrel or cistern can irrigate landscaping outside the normal 4 p.m. to 10 a.m. window. Rainwater systems in Georgia are addressed by the state plumbing and minimum standard codes, and for non-potable uses such as landscape irrigation, simple rain-barrel setups are generally treated as low-regulation; permitting for more complex plumbed systems is determined by local authorities. Public agencies in north Fulton, including the area encompassing Johns Creek, have periodically offered "make-and-take" rain barrel workshops, reflecting an encouraging stance toward harvesting. Because no specific Johns Creek municipal provision governs rain barrels, residents installing a basic collection system for outdoor use typically face no city-specific permit requirement, though any system tied into household plumbing should be checked against state plumbing-code requirements.
