Summary

Ohio Revised Code 3701.344 and Ohio Administrative Code 3701-28 expressly allow rainwater collection for private water systems, with health department approval required for potable use.

(A) Cisterns, reservoir tanks, and hauled water storage tanks shall be watertight with a reasonably smooth, clean interior surface. All concrete tanks shall be made of materials and constructed in accordance with ASTM specifications C 913-2016. All plastic or fiberglass tank materials shall meet NSF standard 61-2016. All joints, connections, and other seams between component parts shall be sealed with nontoxic waterproof material that meets NSF standard 61-2016 or equivalent to prevent the loss of stored water and the infiltration of surface or ground water.

Full Breakdown

Ohio is one of the few states that explicitly regulates and authorizes rainwater as a private water system source. ORC 3701.344 directs the Director of Health to adopt rules, and OAC 3701-28-04 sets standards for cisterns and hauled water. Non-potable outdoor harvesting (rain barrels for gardens) needs no permit statewide. Local jurisdictions cannot prohibit rainwater harvesting because state law affirmatively allows it as a private water system.

Violations & Penalties

Operating an unapproved potable cistern can trigger local health district orders and removal requirements.

Frequently Asked Questions

Do I need a permit for a rain barrel in Ohio?
No state permit is required for non-potable rain barrels collecting roof runoff for landscape watering. Indoor or potable use requires local health department approval under OAC 3701-28.
Can my city ban rainwater harvesting in Ohio?
Cities cannot prohibit rainwater harvesting because state law expressly authorizes it as a private water system. Local rules may regulate cistern construction standards but cannot ban the practice.
