(70 ILCS 2205/17) (from Ch. 42, par. 263)
    Sec. 17. The board of trustees may levy and collect taxes for corporate purposes. Such taxes shall be levied by ordinance specifying the purposes for which the same are required, and a certified copy of such ordinance shall be filed with the county clerk of the county in which the district was organized, on or before the second Tuesday in August, as provided in Section 14-10 of the Property Tax Code. After the assessment for the current year has been equalized by the Department of Revenue, the board of trustees shall, as soon as may be, ascertain and certify to such county clerk the total value of all taxable property lying within the corporate limits of such districts in each of the counties in which the district is situated, if the district is situated in more than one county, as the same is assessed and equalized for State and county purposes for the current year. The county clerk shall ascertain the rate per cent which, upon the total valuation of all such property, ascertained as above stated, would produce a net amount not less than the amount so directed to be levied; and the clerk shall, without delay, certify under his signature and seal of office to the county clerk of such other county, in which a portion of the district is situated such rate per cent; and it shall be the duty of each of the county clerks to extend such tax in a separate column upon the books of the collector or collectors of the State and county taxes for the counties, against all property in their respective counties, within the limits of the district. All taxes so levied and certified shall be collected and enforced in the same manner, and by the same officers as State and county taxes, and shall be paid over by the officers collecting the same, to the treasurer of the sanitary district, in the manner and at the time provided by the Property Tax Code. The aggregate amount of taxes levied for any one year, exclusive of the amount levied for the payment of bonded indebtedness and interest thereon, shall not exceed the rate of .20%, or the rate limitation in effect on July 1, 1967, whichever is greater, of value, as equalized or assessed by the Department of Revenue. The foregoing limitations upon tax rates may be increased or decreased under the referendum provisions of the Property Tax Code.
    In addition to the other taxes authorized by this Section, the board of trustees may levy and collect, without referendum, a tax for the purpose of paying the costs of operation of the chlorination of sewage, or other means of disinfection or additional treatment as may be required by water quality standards approved or adopted by the Pollution Control Board or by the court, which tax is not subject to the rate limitations imposed by this Section but may be extended at a rate not to exceed .03% of the value of all taxable property within the district as equalized or assessed by the Department of Revenue.
    Such tax may be extended at a rate in excess of .03% but not to exceed .05%, providing the question of levying such increase has first been submitted to the voters of such district at any regular election held in such district in accordance with the general election law and has been approved by a majority of such voters voting thereon.
