Illinois Code § 11-147-4

§ 11-147-4.

Any municipality lying wholly or partly within the boundaries of any county which accepts the provisions of "An Act in relation to water supply, drainage, sewage, pollution and flood control in certain counties," approved July 22, 1959, as heretofore or hereafter amended, may contract with such county for water supply or sewerage service to or for the benefit of the inhabitants of the municipality. Any such contract may provide for the periodic payment to the county of a share of the amounts necessary to pay or provide for the expenses of operation and maintenance of the waterworks or sewerage system of the combined waterworks and sewerage system (including insurance) of the county, to pay the principal of and interest on any revenue bonds issued by the county hereunder, and to provide an adequate depreciation fund and to maintain other reserves and sinking funds for the payment of the bonds or the extension or improvement of the waterworks properties or sewage facilities of the county or a combination thereof, as the case may be. Any such contract may be entered into without making a previous appropriation for the expense thereby incurred. Any such contract may be for a term not in excess of 20 years, if the contract is a general obligation of the municipality, or for a term not in excess of 40 years, if the obligation under the contract is payable solely from the revenues derived by the municipality from its water supply or sewerage system. If the contract is payable solely from the revenues derived by the municipality from its water supply or sewerage system, the amounts due under the contract shall be deemed an expense of operating and maintaining the water supply or sewerage system of the municipality.
