Private water systems are regulated by the Ohio Department of Health (ODH) under Sections 3701.344 to 3701.347 of the Ohio Revised Code (ORC) and Chapter 3701-28 of the Ohio Administrative Code (OAC). Private Water Systems are potable water wells, ponds, springs, cisterns and hauled water storage tanks that provide drinking water to fewer than 25 people, less than sixty days out of the year, or have less than 15 service connections. These would include single water supplies that serve homes, small businesses, small churches, small mobile home parks or communities with fewer than 25 residents.
