Ohio Rev. Code Ann. § 6119.061 – Continuing jurisdiction over water resource projects

(A) Whenever any portion of a regional water and sewer district is incorporated as, or annexed to, a municipal corporation, the area so incorporated or annexed shall remain under the jurisdiction of the district for purposes of the acquisition, construction, or operation of a water resource project until the water resource project has been acquired or completed or until the project is abandoned by the district. The board of trustees of the district, unless and until a conveyance is made to a municipal corporation in accordance with division (B) of this section, shall continue to have jurisdiction in the area so incorporated or annexed with respect to the management, maintenance, and operation of all water resource projects so acquired or completed or previously acquired or completed, including the right to establish rules and rates and charges for the use of, and connections to, the projects. The incorporation or annexation of any part of a district shall not affect the legality or enforceability of any public obligations issued or incurred by the district for purposes of this chapter to provide for the payment of the cost of acquisition, construction, maintenance, or operation of any water resource project or the validity of any assessments levied or to be levied on properties within the area to provide for the payment of the cost of acquisition, construction, maintenance, or operation of the project.
(B) The board of trustees of a regional water and sewer district may convey, by mutual agreement, to a municipal corporation any completed water resource project acquired or constructed under this chapter for the use of, or service of property located in, the regional water and sewer district, or any part of that project to which any of the following applies:
1. (1) The project is located within the municipal corporation or within any area that is incorporated as, or annexed to, the municipal corporation.
2. (2) The project serves the municipal corporation or any area that is located within or that is incorporated as, or annexed to, the municipal corporation.
3. (3) The project is connected to water supply or sanitary, drainage, prevention, or replacement facilities of the municipal corporation. The conveyance shall be completed with terms and for consideration as may be negotiated. Upon and after the conveyance, the municipal corporation shall manage, maintain, and operate the water resource project in accordance with the agreement. The board of trustees may retain the right to the joint use of all or part of any project so conveyed for the benefit of the district. Neither the validity of any assessment levied or to be levied, nor the legality or enforceability of any public obligations issued or incurred, to provide for the payment of the cost of the acquisition, construction, maintenance, or operation of the project or any part of the project shall be affected by the conveyance.
