Ohio Rev. Code § 6121.042
For the purpose of paying rates, rentals, or charges imposed pursuant to an order issued under section 6121.041 of the Revised Code, a governmental agency may raise money by any method or combination of methods authorized by law, as if the governmental agency itself were proposing to construct, were constructing, or had constructed waste water facilities. For such purpose the legislative authority of a municipal corporation or the board of county commissioners of a county may by resolution define an area, within their respective jurisdictions, that will derive a benefit from the waste water facilities service provided under an order, and may fix and impose rates or charges upon the owners or occupants of lands within such area.
