Sanitary Sewer

Union County operates a countywide sewer district formed under  Ohio Revised Code Section 6117  . The Union County Commissioners are given the authority to create sewer districts and have the legal responsibility to eliminate unsanitary conditions in the unincorporated areas. The Union County Commissioners have appointed the Union County Engineer as the Sanitary Engineer in responsible charge of the duties prescribed in ORC 6117.

Union County operates several wastewater treatment plants and associated sanitary sewers, forcemains and pump stations. Our wastewater plants all have NPDES (National Pollutant Discharge Elimination System) permits issued by the Ohio Environmental Protection Agency. The NPDES permits enforce regulatory standards for the treated water leaving the plants in order to protect fish and other aquatic life in the streams.
