Rainwater harvesting is legal in Lucas County. Ohio broadly allows collecting rain in rain barrels and cisterns, and neither the county nor Toledo bans it. If a cistern feeds indoor plumbing, Ohio private-water-system rules apply.
Ohio is a permissive state for rainwater collection — barrels and cisterns for outdoor irrigation are unrestricted, and Lucas County imposes no cap. There is no county or Toledo ordinance prohibiting rain barrels. The one regulated case is a cistern used as a private water system that supplies water for human consumption inside a dwelling; those fall under Ohio Administrative Code OAC 3701-28 (private water systems), administered locally by the Toledo-Lucas County Health Department, which requires proper construction and, in some cases, a permit. Simple garden rain barrels do not trigger that.
No penalties for ordinary rain-barrel use. A cistern serving indoor drinking water without meeting OAC 3701-28 private-water-system standards can be cited by the health department.
