(2) A district may annually also assess, levy and collect a special tax upon all such property in an amount sufficient to pay the yearly interest on bonds theretofore issued by the district and then outstanding, together with any portion of the principal of such bonds maturing within the year. The special tax shall be applied only in payment of interest and principal of bonds issued by the district, but the district may apply any funds it may have toward payment of principal and interest of any such bonds.
(3) Taxes shall be levied in each year and returned to the county officer whose duty it is to extend the tax roll by the time required by law for city taxes to be levied and returned.
(4) Taxes levied by the district shall become payable at the same time and be collected by the same officer who collects county taxes, and the proceeds shall be turned over to the district according to law. The county officer whose duty it is to extend the county levy shall extend the levy of the district in the same manner as city taxes are extended.
(5) Property is subject to sale for nonpayment of taxes levied by the district in like manner and with like effect as in the case of county and state taxes.
