A commission may from time to time issue its revenue bonds in such principal amounts as the commission shall deem necessary to provide sufficient funds to carry out any of its corporate purposes and powers, including, without limitation, developing, acquiring, constructing, extending or improving a waterworks system or common source of supply of water, or any combination thereof, the funding or refunding of the principal of, redemption premium, if any, and interest on, any bonds issued by it whether or not such bonds or interest to be funded or refunded have or have not become due, the payment of engineering, legal and other expenses, together with interest to a date one year subsequent to the estimated date of completion of the project, the establishment or increase of reserves to secure or to pay such bonds and interest thereon, the providing of working capital and the payment of all other costs or expenses of the commission incident to and necessary or convenient to carry out its corporate purposes and powers. These bonds shall have all the qualities of negotiable instruments under the laws of this State and shall not constitute indebtedness of any of the municipalities constituting the commission.
Every issue of bonds of such commission shall be payable out of the revenues to be derived pursuant to contracts with the specified municipalities and participating water commissions or by virtue of the operation of any properties acquired or to be acquired or constructed. A commission may issue such types of bonds as it may determine, including bonds as to which the principal and interest are payable exclusively from the revenues from one or more projects, or from an interest therein or a right to the products and services thereof, or from one or more revenue producing contracts made by the commission, or its revenues generally. Any such bonds may be additionally secured by a pledge of any grant, subsidy, or contribution from the United States, the State of Illinois, or any unit of local government, or any combination thereof.
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 may be issued in one or more series, and shall bear such date or dates, mature at such time or times within the estimated period of usefulness of the project involved and in any event not more than 50 years from the date thereof, bear interest at such rate or rates as authorized under Section 2 of "An Act to authorize public corporations to issue bonds, other evidences of indebtedness and tax anticipation warrants subject to interest rate limitations set forth therein", approved May 26, 1970, as now or hereafter amended, which rates may be fixed or variable, be in such denominations, be in such form, either coupon or registered, carry such conversion, registration, and exchange privileges, have such rank or priority, be executed in such manner, be payable in such medium of payment at such place or places within or without the State of Illinois, be subject to such terms of redemption with or without premium, and contain or be subject to such other terms as the ordinance or resolution may provide, and shall not be restricted by the provisions of any other law limiting the amounts, maturities, interest rates, or other terms of obligations of public agencies or private persons. The bonds shall be sold in such manner as the commission shall determine, at private or public sale. 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 135 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 135.
The amendatory Acts of 1971, 1972, 1973, 1975 and 1981 are not a limit upon any municipality which is a home rule unit.
