(40 ILCS 5/13-503) (from Ch. 108 1/2, par. 13-503)
    Sec. 13-503. Tax levy. Until fiscal year 2013, the Water Reclamation District shall annually levy a tax upon all the taxable real property within the District at a rate which, when extended, will produce a sum that (i) when added to the amounts deducted from the salaries of employees, interest income on investments, and other income, will be sufficient to meet the requirements of the Fund on an actuarially funded basis, but (ii) shall not exceed an amount equal to the total amount of contributions by the employees to the Fund made in the calendar year 2 years prior to the year for which the tax is levied, multiplied by 2.19, except that the amount of employee contributions made on or after January 1, 2003 towards the purchase of additional optional benefits under Section 13-304.1 shall only be multiplied by 1.00.
    Beginning in fiscal year 2013, the District shall annually levy a tax upon all the taxable real property within the District at a rate which, when extended, will produce a sum that (i) will be sufficient to meet the Fund's actuarially determined contribution requirement, but (ii) shall not exceed an amount equal to the total employee contributions 2 years prior multiplied by 4.19. The actuarially determined contribution requirement is equal to the employer's normal cost plus the annual amount needed to amortize the unfunded liability by the year 2050 as a level percent of payroll. The funding goal is to attain a funded ratio of 100% by the year 2050, with the funded ratio being the ratio of the actuarial value of assets to the total actuarial liability.
    The tax shall be levied and collected in the same manner as the general taxes of the District.
    The tax shall be exclusive of and in addition to the amount of tax the District is now or may hereafter be authorized to levy for general purposes under the Metropolitan Water Reclamation District Act or under any other laws which may limit the amount of tax for general purposes. The county clerk of any county, in reducing tax levies as may be authorized by law, shall not consider any such tax as a part of the general tax levy for District purposes, and shall not include the same in any limitation of the percent of the assessed valuation upon which taxes are required to be extended.
    Revenues derived from the tax shall be paid to the Fund for the benefit of the Fund, except for the amount of revenue to be retained by the District and used to pay principal and interest on bonds issued for the sole purpose of making contributions to the Fund as set forth in Section 9.6a of the Metropolitan Water Reclamation District Act.
    If the funds available for the purposes of this Article are insufficient during any year to meet the requirements of this Article, the District may issue tax anticipation warrants or notes, as provided by law, against the current tax levy.
    The Board shall submit annually to the Board of Commissioners of the District an estimate of the amount required to be raised by taxation for the purposes of the Fund. The Board of Commissioners shall review the estimate and determine the tax to be levied for such purposes.
