(A)

1. (1) After the formation of any county sewer district, the board of county commissioners may contract with a person, political subdivision, unincorporated area, or public agency located outside of the district for any of the following:

   1. (a) Depositing sewage or drainage from outside of the district in facilities acquired or constructed or to be acquired or constructed by the county to serve the district;
   2. (b) The treatment, disposal, and disposition of the sewage or drainage, on terms that the board considers equitable;
   3. (c) The provision of water supply services.
2. (2) A person, political subdivision, unincorporated area, or public agency located outside of a county sewer district may apply to the board of county commissioners for the provision of the services specified in division (A)(1)(a), (b), or (c) of this section.
3. (3) The amount to be paid by the person, political subdivision, unincorporated area, or public agency to reimburse the county for costs of acquiring or constructing those facilities shall not be less than the original or comparable assessment for similar property within the district or, in the absence of an original or comparable assessment, an amount that is found by the board to be reasonable and fairly reflective of that portion of the cost of those facilities attributable to the properties to be served. The board shall appropriate any moneys received for that service to and for the use and benefit of the district. The board may collect the amount to be paid by the person, political subdivision, unincorporated area, or public agency in full, in cash or in installments as a part of a connection charge to be collected in accordance with division (B) or (D) of section 6117.02 of the Revised Code, or if the properties to be served are located within the county, the same amount may be assessed against those properties, and, in that event, the manner of making the assessment, together with the notice of it, shall be as provided in this chapter.
