(70 ILCS 605/4-17) (from Ch. 42, par. 4-17)
    Sec. 4-17. Acquisition of property - Eminent domain. Whenever an order has been entered by the court authorizing the performance of any work, either within or outside of the district, the commissioners shall proceed to acquire all lands, easements, rights-of-way and other property or interests therein which may be necessary to the performance of such work. The commissioners may enter into agreements with landowners to pay reasonable compensation therefor and may use or commit the corporate funds of the district for such purposes without regard to whether such funds are on hand or are yet to be levied or collected. Whenever the commissioners are unable to agree with any landowner or other interested person on the amount of compensation to be paid, or whenever any person interested is not competent to contract or his name or residence is unknown or he is a non-resident of this state, then the commissioners may, on behalf of the district, acquire any such lands, easements, rights-of-way, properties and interests, whether privately owned, publicly owned or held for the use of the public, by the exercise of the right of eminent domain.
    (a) Complaints seeking to take property in the exercise of the right of eminent domain may be filed by the commissioners in any court of competent jurisdiction, in the manner now or as may hereafter be provided by statute.
    (b) When the property sought to be taken is situated within the boundaries of the district, or when the property sought to be taken is not situated within the boundaries of the district but is situated within the county in which the district is organized, the commissioners may acquire the same and have the compensation fixed in conjunction with and as a part of their assessment proceedings. The commissioners shall, in such event, set forth in the assessment roll, or in an application filed therewith, a description of the property sought to be taken and the amount of the compensation allowed by them. The property so sought to be taken shall be described by reference to the plats, plans and specifications on file with and approved by the court, by metes and bounds, by setting forth in general terms a description of the course, width and area of the right-of-way or easement to be acquired and a general description of the property over, across or upon which the same is to be located, or by any combination of these methods, or by any other method which will sufficiently describe the property sought to be taken. The compensation for property taken and the damages to property not taken, if any, shall thereupon be fixed and determined at the hearing on the assessment roll.
    (c) Every owner of property sought to be taken and every other person interested in such property shall be made a party defendant in the proceeding and shall be served with process or given notice as in other civil cases.
    (d) When the court finds that it is in the best interests of the district to acquire the fee instead of a necessary lesser interest in land and that the fee can be acquired by agreement with the landowner, then the court may authorize the commissioners to purchase the fee. Commissioners may, on behalf of the district, accept a gift or legacy of the fee or any lesser interest in land.
