The board of trustees of any sanitary district may arrange to provide for the benefit of employees and trustees of the sanitary district group life, health, accident, hospital and medical insurance, or any one or any combination of such types of insurance. The Board of trustees may also elect to self insure the district's employees. In the event the board arranges to provide insurance, such insurance may include provision for employees and trustees who rely on treatment by prayer or spiritual means alone for healing in accordance with the tenets and practice of a well recognized religious denomination. The board of trustees may provide for payment by the sanitary district of the premium or charge for such insurance.
If the board of trustees elects to provide the insurance, but does not provide for a plan pursuant to which the sanitary district pays the premium or charge for any group insurance plan, the board of trustees may provide for the withholding and deducting from the compensation of such of the employees and trustees as consent thereto the premium or charge for any group life, health, accident, hospital and medical insurance.
If the board of trustees elects to provide insurance under the provisions of this Section, it may exercise the powers granted in this Section only if the kinds of such group insurance are obtained from any insurance company authorized to do business in the State of Illinois or any other for-profit or not-for-profit organization or service offering similar coverage including without limitation, hospitals, clinics, health maintenance organizations, and physicians' groups. The board of trustees may enact an ordinance prescribing the method of operation of the insurance or self-insurance program and for entering into contracts with for-profit and not-for-profit organizations or services providing health care services.
