(65 ILCS 5/11-147-1) (from Ch. 24, par. 11-147-1)
    Sec. 11-147-1. Whenever a municipality, drainage district, sanitary district, or other municipal corporation is adjacent to any other municipality, drainage district, sanitary district, or other municipal corporation the adjacent municipal corporations have the power to contract with each other, upon such terms as may be agreed upon between them, for the perpetual or temporary use and benefit by one of them of any sewer or drain, or of any system of sewerage or drainage or part thereof, or of any sewage disposal or sewage treatment plants and works, heretofore or hereafter constructed by the other. Any such sewer or drain, or system of sewerage or drainage or part thereof, or sewage disposal or sewage treatment plants and work, heretofore or hereafter constructed by one such municipal corporation may be extended or furnished to the inhabitants of the other. Such municipal corporations may by contract with each other provide for the joint construction of any sewer or drain or sewage disposal or sewage treatment plants and works by the municipal corporations so contracting, and for the common use thereof by the inhabitants of the contracting municipal corporations. In addition, whenever a sanitary district has acquired an easement granting the sanitary district the right to construct or operate a sanitary sewer system or part of a sanitary sewer system over property that connects the sanitary district to a municipality, the municipality and the sanitary district may enter into a contract for the use of the sanitary sewer system regardless of whether the sanitary district is adjacent to the municipality.
