MSD was formed in 1968 as a county sewer district under state law and is governed by a 50-year agreement between the City of Cincinnati and Hamilton County. The City of Cincinnati is solely responsible for operating and managing MSD. Per the 1968 Agreement, the Hamilton County Board of County Commissioners establishes Rules and Regulations for MSD that outline the requirements all users of the system must comply with in order to ensure MSD meets all Federal and State regulations for environmental protection, worker safety and public health.

Please note... All new and existing discharges to the system shall be subject to these Rules & Regulations. Commercial and industrial customers that discharge sanitary sewerage, industrial wastes, water or other liquids – other than “normal residential strength sewage” – either directly or indirectly to the District may pay a wastewater treatment system surcharge. If you have questions concerning the MSD Pretreatment Program, which regulates such users, please contact MSD's Regulatory Compliance and Safety Division, Industrial Waste Section at (513) 557-7000 or visit Industrial User Resources.
