2019 Sewer and Water Rate Survey

Ohio EPA has finalized and posted the 2019 Sewer and Water Rate Survey for calendar year 2019. The purpose of the annual Sewer and Water Rate Survey is to collect and publish Ohio residential sewer and water rates. The Economic Analysis Unit annually surveys sewer and water rates charged by Ohio cities, villages and special districts during the prior calendar year. Annual rates are calculated for residential customers within municipal limits given an assumed monthly water consumption level of 7,756 gallons (or 1,037 cubic feet) per household. Rate calculations do not include charges levied through income or property taxes. Historic survey data and sewer and water rates for more than 500 cities, villages and districts during the 2003-2018 periods are available online at Ohio EPA's Office of Fiscal Administration web page.
