The board of trustees, immediately after their appointment and at their first meeting in May of each year thereafter, shall elect one of their number as president, one of their number as vice-president, and from or outside of their membership a clerk and an assistant clerk. In case of the death, resignation, absence from the State, or other disability of the president, the president's powers and duties shall devolve upon the vice-president until the president's disability is removed or until a successor to the president is appointed under this Act. The board may select a treasurer, an engineer, and an attorney for the district as well as a board of local improvements consisting of 3 members all of whom may be trustees or other citizens of the sanitary district. The board may appoint other officers and hire employees to manage and control the operations of the district as it considers necessary. All persons elected by the board shall hold their respective offices at the pleasure of the board and shall give such bond as may be required by the board. The board may prescribe duties and fix the compensation of all the officers and employees of the sanitary district. However, no member of the board of trustees shall receive more than $6,000 per year as compensation for performing his or her duties as trustee.
The board of trustees has full power to pass all necessary ordinances, rules, and regulations for the proper management and to conduct the business of the board and the corporation and for carrying into effect the objects for which the sanitary district was formed. These ordinances may provide a fine for each offense of not less than $100 or more than $1,000. Each day that a violation continues shall constitute a separate offense.
