Ohio Rev. Code Ann. § 743.08

The legislative authority of a municipal corporation in which water works are situated or are in the process of construction may appoint a committee for the investigation of all books and papers, and all matters pertaining to the management of the water works, at least once a year, and more often, if necessary by reason of the neglect of duty or malfeasance on the part of any officer of such water works. Any such officer found by the committee to be so offending shall be liable to removal from office by the legislative authority.
