Upon the adoption of such an ordinance or resolution by the corporate authorities of any such municipality, the mayor or president, with the approval of the corporate authorities, shall appoint a commissioner. If under Section 11-135-3 a water commission meets the participatory requirements, that water commission shall appoint a commissioner. The commissioners so appointed by each of such municipalities and participatory water commissions together with a like commissioner appointed by the presiding officer of the county board with the advice and consent of the county board of the county in which the major part of the works of the water commission are, or are to be, located, shall constitute a commission and public corporation with the powers and duties specified in this Division 135. The corporate name of the commission shall be "(here insert an appropriate name indicative of the area) Water Commission" and as such the Commission may contract and be contracted with, and sue and be sued.
The commissioners so appointed shall serve for a term of 6 years, or until their successors have been appointed and have qualified in the same manner as the original appointments, except that the commissioners first appointed shall determine by lot at their first meeting the respective commissioners whose terms shall be for 2, 4 and 6 years from the date of that meeting. Each commissioner appointed by a mayor or president shall be an elector or the chief administrator of the municipality for which he acts as commissioner, and the commissioner appointed by the presiding officer of the county board shall be an elector of the county in which the major works of the water commission are, or are to be, located. Any commissioner so appointed may be a member of the governing board or officer of the municipality or county from which the appointment is made. A commissioner is eligible for reappointment upon the expiration of his term. A vacancy shall be filled for the balance of the unexpired term of the person who has ceased to hold office by the mayor, president or county board presiding officer who initially made such appointment in the same manner as the original appointment. Each commissioner shall receive the same compensation, as determined by the appointing authority, which shall not be more than $2,000 per year, except that no commissioner who is a member of the governing board or officer or employee of the municipality or county from which the appointment is made may receive any compensation for serving as commissioner. Each commissioner shall furnish a bond for the faithful performance of his official duties. This bond shall not be less than $5,000 and its costs shall be paid by the commission.
Each commissioner may be removed for any cause for which any other municipal officer may be removed. No commissioner, or employee of the commission, and no mayor, or president, or other member of the corporate authorities, or any employee of any of the municipalities, shall be interested directly or indirectly in any contract or job of work or materials, or the profits thereof, or services to be performed for or by the commission.
A violation of any of the foregoing provisions of this section is a Class C misdemeanor. A conviction is cause for the removal of a person from his office or employment.
