Illinois Statutes Chapter 70. Special Districts § 3710/3. Board of trustees

(1) If the district is wholly contained within a single county the trustees for the district shall be appointed by the presiding officer of the county board with the advice and consent of the county board;

(2) If the district is located in more than one county, the number of trustees who are residents of a county shall be in proportion, as nearly as practicable, to the number of residents of the district who reside in that county in relation to the total population of the district.

Upon the expiration of the term of a trustee who is in office on the effective date of this amendatory Act of 1975, the successor shall be a resident of whichever county is entitled to such representation in order to bring about the proportional representation required herein, and he shall be appointed by the county board of that county, or in the case of a home rule county as defined by Article VII, Section 6 of the Constitution of 1970, the chief executive officer of that county, with the advice and consent of the county board.

Thereafter, each trustee shall be succeeded by a resident of the same county who shall be appointed by the same appointing authority; however, the provisions of the preceding paragraph shall apply to the appointment of the successor to each trustee who is in office at the time of the publication of each decennial Federal census of population.

Within 60 days after the creation of a water service district as provided in Section 1 the appropriate appointing authority shall appoint 3 trustees.

The trustees shall hold their offices for one, 2 and 3 years from the first Monday of May next after their appointment and until their successors have been appointed and qualified and thereafter on or before the second Monday in April of each year the appointing authority shall appoint one trustee whose term shall be for 3 years commencing on the first Monday in May next after they are respectively appointed. The length of term of the first trustees shall be determined by lot at their first meeting.

The appointing authority shall require each of the trustees to enter into bond with security to be approved by the appointing authority in such sum as the appointing authority may determine.

A majority of the board of trustees shall constitute a quorum. No trustee or employee of such district shall be directly or indirectly interested financially in any contract, work or business or the sale of any article, the expense, price or consideration of which is paid by the district. The trustees shall provide and adopt a corporate seal for the district.
