The board of trustees may levy and collect other taxes for corporate purposes upon property within the territorial limits of the sanitary district, the aggregate amount of which for each year may not exceed .083% of value, as equalized or assessed by the Department of Revenue, except that if a higher rate has been established by referendum before August 2, 1965, it shall continue. If the board desires to levy such taxes at a rate in excess of .083% but not in excess of .35% of the value of all taxable property within the district as equalized or assessed by the Department of Revenue, they shall order the question to be submitted at an election to be held within the district. The certification and submission of the question and the election shall be governed by the general election law. Upon the filing of a petition signed by 10% of the registered voters of the district, the right to levy an additional tax, or any portion thereof, authorized by the legal voters, may at any time after one or more tax levies thereunder, be terminated by a majority vote of the electors of the district at a referendum. The trustees of the district shall certify the proposition to the proper election officials, who shall submit the proposition at an election in accordance with the general election law.
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 cost 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.
The board shall cause the amount required to be raised by taxation in each year to be certified to the county clerk as provided in Section 8-15 of the Property Tax Code . 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 General Revenue Law of Illinois.
The treasurer shall, when the moneys of the district are deposited with any bank or savings and loan association, require that bank or savings and loan association to pay the same rates of interest for the moneys deposited as the bank or savings and loan association is accustomed to pay to depositors under like circumstances, in the usual course of its business. All interest so paid shall be placed in the general funds of the district, to be used as other moneys belonging to the district raised by general taxation or sale of water.
No bank or savings and loan association shall receive public funds as permitted by this Section, unless it has complied with the requirements established pursuant to Section 6 of "An Act relating to certain investments of public funds by public agencies", approved July 23, 1943, as now or hereafter amended.
In addition to the foregoing, the Board of Trustees shall have all of the powers set forth in Division 7 of Article 8 of the Illinois Municipal Code until September 10, 1986.
