A municipality issuing refunding special assessment warrants or bonds shall preserve and enforce, for the security of the refunding warrants or bonds, all of the rights and duties which constituted security for the refunded warrants or bonds. At the date of the maturity of the last maturing warrant or bond of the original issue, the governing body shall levy a tax for the payment of any deficiency in the special improvement fund against which the refunded special assessment warrants or bonds were drawn. Such tax may be made payable in the years and in the amounts required to pay the principal of and interest on the refunding warrants or bonds as the same becomes due.
