Payment for any improvement done or performed under the provisions of this Division 2, to be paid for out of any special assessment or special tax levied in installments, as provided in this Division 2, may be made in the bonds provided for in this Division 2. In the event payment is made in the bonds authorized under Section 9-2-119, the first installment of such special assessment or special tax shall be paid to the person entitled thereto on the contract for that work. If this first installment is not collected when payments fall due, vouchers therefor may be issued, payable out of the first installment when collected. These vouchers shall bear interest at the rate specified in the ordinance referred to in § 9-2-10 of the Illinois Municipal Code for bonds and not more than the rate the installments of the assessment against which the vouchers are issued bear, payable annually, and shall be signed by such officers as may be prescribed by ordinance.
     In the event payment is made in the bonds authorized under Section 9-2-127, the first installment of such special assessment or special tax and all other installments thereof shall be held and used to pay the bonds and interest thereon as provided in Section 9-2-127.
     However, in municipalities having a population of less than 500,000, where the ordinance for the improvement provides for the collection of costs, such costs shall be first paid out of this first installment and may be included in and evidenced by vouchers issued as provided in this Section 9-2-131.
