Rainwater harvesting for outdoor use is legal and encouraged in Toledo. Ohio has no state restrictions on residential rain barrels. Larger cistern systems for indoor potable use must meet Ohio plumbing and health codes.
Ohio is one of the most permissive states for rainwater harvesting. Residential rain barrels and small cisterns collecting rooftop runoff for landscape irrigation are legal statewide and in Toledo with no permit required. Lucas County Soil and Water Conservation District periodically offers discounted rain-barrel sales and rain-garden workshops as part of stormwater education under the Maumee River watershed restoration effort. Systems used for indoor non-potable use (toilet flushing, laundry) must comply with the Ohio Plumbing Code and require backflow prevention. Cisterns used as a potable water source require Ohio Department of Health approval under OAC 3701-28 and are rare in a city with municipal Lake Erie water supply. Rain gardens and bioswales are encouraged best-management practices for stormwater reduction.
