For the purpose of paying the cost of the acquisition by condemnation, purchase or otherwise and of the construction of any water supply or other water properties of the authority and the improvement or extension thereof from time to time, including engineering and all other expenses, and also for reimbursing or paying the cost and expense of creating the authority, the board of trustees of any such authority is authorized to issue and sell revenue bonds of the authority, payable solely from the income and revenue derived from the operation of the water supply or other waterworks properties of the authority.
All such bonds shall be authorized by ordinance or resolution to be adopted by the board of trustees, shall bear such date or dates, mature at such time or times not exceeding 40 years from their respective dates, may bear interest at such rate or rates not exceeding the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, may be in such form, may carry such registration privileges, may be executed in such manner, may be payable at such place or places, may be subject to redemption in such manner, and upon such terms with or without premium as is stated on the face thereof, and may be executed in such manner by such officers of the authority, and may contain such terms and covenants, all as provided by the ordinance or resolution authorizing their issue.
Such bonds shall be sold in such manner as the board of trustees shall determine, and if issued to bear interest at the rate of the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, shall be sold for not less than par and accrued interest; provided, however, the selling price of any bonds bearing 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 the sale of said bonds 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 absolute maturity, according to standard tables of bond values.
Notwithstanding the form or tenure thereof, and in the absence of expressed recitals on the face thereof that said bonds are nonnegotiable, all such bonds shall be negotiable instruments.
To secure payment of any and all of such bonds such ordinance or resolution shall set forth the covenants and undertakings of the authority in connection with the issuance thereof and the issuance of additional bonds payable from the revenues or income to be derived from the operation of the water supply or the waterworks properties of such authority, as well as the use and operation thereof.
In case any officer whose signature appears on said bonds or coupons attached thereto shall cease to be such officer before the delivery of the bonds to the purchaser, such signature shall nevertheless be valid and sufficient for all purposes to the same effect as if he had remained in office until the delivery of the bonds and the signature of any officer holding office at the time any bond was signed shall be valid, regardless of whether or not said officer held such office on the day on which the bonds are dated.
Under no circumstances shall any bonds issued pursuant to the provisions of this Act be or become an indebtedness or an obligation of the authority payable from taxes and shall not in any event constitute an indebtedness of such authority within the meaning of the constitutional provisions or limitations, and such fact shall be plainly stated on the face of each bond.
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.
