The Ohio Department of Health (ODH) regulates sewage treatment systems across the state through statutory authority established under Ohio Revised Code (ORC) Chapter 3718 and Ohio Administrative Code Chapter 3701-29, which was updated and became effective on Jan. 1, 2015. Permitting, inspections and enforcement are conducted by the local health districts and local health districts may adopt more stringent rules and standards.
Sewage treatment systems include one, and three-family dwellings and small flow on-site sewage treatment systems (facilities that treat up to 1,000 gallons per day). Proper system siting and design, soils evaluation, system owner education and operation inspections and maintenance of systems are essential to help prevent future contamination and public health nuisances.
