(65 ILCS 5/11-130-5) (from Ch. 24, par. 11-130-5)
    Sec. 11-130-5. Bonds provided for in this Division 130 shall be issued in such amounts as may be necessary to provide sufficient funds to pay all costs of the purchase or construction, including engineering, legal, and other expenses, together with interest to a date 6 months subsequent to the estimated date of completion. Bonds issued under this Division 130 are negotiable instruments. They shall be executed by the mayor, or president and by the municipal clerk and shall be sealed with the corporate seal of the municipality. In case any of the officers whose signatures appear on the bonds, or coupons attached thereto, ceases to hold his office before delivery of the bonds, his signature nevertheless shall be valid and sufficient for all purposes the same as if it had remained in office until the delivery of the bonds. The bonds may be sold at not less than 90 cents on the dollar, and the proceeds derived therefrom shall be used exclusively for the purposes for which the bonds were issued. The bonds may be sold at one time or in parcels as funds are needed, but no bond shall be delivered until bids for the construction, or the offer to sell, in the case of a purchase, has been received, or judgment has been entered in the event of a condemnation, and it is apparent that the authorized bonds will pay for the contemplated waterworks.
