For the purpose of acquiring such a waterworks system or sources of supply of water or sewer systems, or any combination thereof or for making improvements and extensions to such a waterworks system or sources of supply of water or sewer systems, or any combination thereof, such a commission is authorized to issue revenue bonds payable solely from the revenue to be derived pursuant to any contracts with the specified municipalities or with any person, firm or corporation or by virtue of the operation of any properties acquired or to be acquired. These bonds shall not constitute an indebtedness of any of the municipalities represented by the commission. The bonds shall bear interest at a rate not exceeding the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, payable semiannually, and shall mature within the period of usefulness of the property to be acquired or constructed from the proceeds thereof. This period shall be conclusively determined by the commission at or before the time of the issuance of the bonds, and in no event shall any of the bonds be issued with a maturity more than 50 years from the date thereof. The bonds shall be sold in such manner as the commission shall determine, except that if issued to bear interest at the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, the bonds shall be sold for not less than par and accrued interest, and except that the selling price of any bond bearing interest at less than the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, shall be such that the interest cost of the money received from that bond shall not exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, computed to maturity, according to standard tables of bond values.
Before the treasurer of the commission is entitled to receive the proceeds of the sale of such a bond issue, he shall supply a corporate surety bond in an amount equivalent to the amount of funds to be derived from the sale of the bonds, and, in addition thereto, he shall supply a separate corporate surety bond for the faithful accounting of any funds that may come into his possession in an amount equal to the amount of funds likely to come into his hands in any one year from the revenue to be derived from the operation of any of the properties of the commission. The cost of these surety bonds shall be paid by the commission.
The revenue bonds shall be issued pursuant to an ordinance or resolution and shall be in such form and be executed in such manner as may be prescribed by the ordinance or resolution. It shall not be necessary that the ordinance or resolution refer to plans and specifications nor that there be on file for public inspection prior to the adoption of such ordinance detailed plans and specifications of the project. This ordinance or resolution may contain such covenants and restrictions in relation to the operation of the properties under the control of the commission and the issuance of additional revenue bonds thereafter as may be deemed necessary or advisable for the assurance of payment of the bonds thereby authorized and as may be thereafter issued. It shall be plainly stated on the face of each bond that it does not constitute an indebtedness of any municipality represented by the commission within the meaning of any statutory or constitutional limitation. Upon the issuance of revenue bonds, the revenue of the commission derived pursuant to contracts entered into for the sale of water to the specified municipalities and from the operation of its properties, shall be accounted for as provided in the ordinance or resolution authorizing the issuance of the bonds. Any commission created under the provisions of this Division 136 may also issue new bonds for the purpose of providing funds for the payment of unpaid bonds in accordance with the procedure prescribed by this Division 136.
With respect to instruments for the payment of money issued under this Section either before, on, or after the effective date of this amendatory Act of 1989, it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Act that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Act that may appear to be or to have been more restrictive than those Acts.
The amendatory Acts of 1971, 1972 and 1973 are not a limit upon any municipality which is a home rule unit.
