About MSD

The Metropolitan Sewer District of Greater Cincinnati (known as MSD) protects public health and the environment through the safe and efficient collection and treatment of wastewater for 43 of the 49 political subdivisions in Hamilton County, Ohio, and small parts of Butler, Clermont, and Warren counties.

MSD's service area encompasses 290+ square miles and serves a population of more than 850,000. MSD maintains about 3,000 miles of sanitary and combined sewers and operates seven major wastewater treatment plants, more than 100 pump stations, two package treatment plants and several high-rate treatment facilities. About 160 million gallons of wastewater is treated daily. Learn more about MSD's facilities.

Organization & Structure

MSD was formed in 1968 as a county sewer district under state law. Prior to 1968, the City of Cincinnati operated an independent municipal sewer district that served city residents and 23 suburban communities. MSD is governed by a 50-year agreement between the City of Cincinnati and Hamilton County, known as the 1968 Agreement. As set forth in this Agreement, the City is responsible for the management and operation of the sewer district, while the Board of County Commissioners of Hamilton County, Ohio retains the authority to establish sewer service charges, adopt rules and regulations, and approve operating and capital improvement program (CIP) budgets. The agreement expired on April 30, 2018, was extended to September 30, 2018, and then extended indefinitely by U.S. District Judge Michael Barrett.

MSD has more than 600 employees who work for the City of Cincinnati.

Leadership

Diana Christy has served as the Interim Director of MSD since June 18, 2018. She was appointed by Acting City Manager Patrick Duhaney.
