Except as otherwise provided in this Section, all contracts for purchases or sales by the sanitary district, the expense of which will exceed the mandatory competitive bid threshold, shall be let to the lowest responsible bidder therefor upon not less than 14 days' public notice of the terms and conditions upon which the contract is to be let, having been given by publication in a daily or weekly newspaper published in the district or, if there is no newspaper published in the district, in a newspaper published in the county and having general circulation in the district, and the board may reject any and all bids, and readvertise. Contracts for services in excess of the mandatory competitive bid threshold may, subject to the provisions of this Section, be let by competitive bidding at the discretion of the district board of trustees. All contracts for purchases or sales that will not exceed the mandatory competitive bid threshold may be made in the open market without publication in a newspaper as above provided, but whenever practical shall be based on at least 3 competitive bids. For purposes of this Section, the "mandatory competitive bid threshold" is a dollar amount equal to 0.1% of the total general fixed assets of the district as reported in the most recent required audit report. In no event, however, shall the mandatory competitive bid threshold dollar amount be less than $10,000, nor more than $40,000.
If a unit of local government performs non-emergency construction, alteration, repair, improvement, or maintenance work on the public way, the sanitary district may enter into an intergovernmental agreement with the unit of local government allowing similar construction work to be performed by the sanitary district on the same project, in an amount no greater than $100,000, to save taxpayer funds and eliminate duplication of government effort. The sanitary district and the other unit of local government shall, before work is performed by either unit of local government on a project, adopt a resolution by a majority vote of both governing bodies certifying work will occur at a specific location, the reasons why both units of local government require work to be performed in the same location, and the projected cost savings if work is performed by both units of local government on the same project. Officials or employees of the sanitary district may, if authorized by resolution, purchase in the open market any supplies, materials, equipment, or services for use within the project in an amount no greater than $100,000 without advertisement or without filing a requisition or estimate. A full written account of each project performed by the sanitary district and a requisition for the materials, supplies, equipment, and services used by the sanitary district required to complete the project must be submitted by the officials or employees authorized to make purchases to the board of trustees of the sanitary district no later than 30 days after purchase. The full written account must be available for public inspection for at least one year after expenditures are made.
Cash, a cashier's check, a certified check, or a bid bond with adequate surety approved by the board of trustees as a deposit of good faith, in a reasonable amount, but not in excess of 10% of the contract amount, may be required of each bidder by the district on all bids involving amounts in excess of the mandatory competitive bid threshold and, if so required, the advertisement for bids shall so specify.
Contracts which by their nature are not adapted to award by competitive bidding, including, without limitation, contracts for the services of individuals, groups or firms possessing a high degree of professional skill where the ability or fitness of the individual or organization plays an important part, contracts for financial management services undertaken pursuant to the Public Funds Investment Act, contracts for the purchase or sale of utilities, contracts for materials economically procurable only from a single source of supply and leases of real property where the sanitary district is the lessee shall not be subject to the competitive bidding requirements of this Section.
Where the board of trustees declares, by a 2/3 vote of all members of the board, that there exists an emergency affecting the public health or safety, contracts totaling not more than the emergency contract cap may be let to the extent necessary to resolve such emergency without public advertisement or competitive bidding. For purposes of this Section, the "emergency contract cap" is a dollar amount equal to 0.4% of the total general fixed assets of the district as reported in the most recent required audit report. In no event, however, shall the emergency contract cap dollar amount be less than $40,000, nor more than $100,000. The ordinance or resolution embodying the emergency declaration shall contain the date upon which such emergency will terminate. The board of trustees may extend the termination date if in its judgment the circumstances so require. A full written account of the emergency, together with a requisition for the materials, supplies, labor or equipment required therefor shall be submitted immediately upon completion and shall be open to public inspection for a period of at least one year subsequent to the date of such emergency purchase. Within 30 days after the passage of the resolution or ordinance declaring an emergency affecting the public health or safety, the District shall submit to the Illinois Environmental Protection Agency the full written account of any such emergency along with a copy of the resolution or ordinance declaring the emergency, in accordance with requirements as may be provided by rule.
