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 one commissioner for each 5,000 population, or part thereof. The commissioners so appointed by each of such municipalities, together with a like commissioner appointed by the chairman of the county board of the county in which the municipality having the greatest population is situated, shall constitute a commission and public corporation with the powers and duties specified in this Division 136. The corporate name of the commission shall be "(here insert appropriate name indicative of the area) Water Commission" or "Water and Sewer 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. Each commissioner shall be an elector of the municipality for which he acts as commissioner. However, no person shall be eligible for appointment, if he has held an elective office in the state, county or municipality, until one year after the expiration of the term for which he was elected. A commissioner is eligible for reappointment upon the expiration of his term. A vacancy shall be filled for the balance of the unexpired term in the same manner as that prescribed for the appointment of the person who has ceased to hold office. Each commissioner shall receive the same compensation which shall not be more than $1,000 per year. 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 contractor-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. Any member of the commission or any employee thereof who in any manner contributes money, labor, or other valuable thing to any person for election purposes in any election for office in any of the municipalities which are furnished water by the commission is guilty of a Class C misdemeanor.
