If funds on hand or unappropriated are insufficient for the purposes of this Section, the necessary funds shall be raised by the issuance of either general obligation or revenue bonds. If the estimated cost of the steps necessary to be taken by such public body to comply with such order is such that the bond issue, necessary to finance such project, would not raise the total outstanding bonded indebtedness of such public body in excess of any limit which may be imposed upon such indebtedness, the necessary bonds may be issued as a direct obligation of such public body and retired pursuant to general law governing the issue of such bonds. No election or referendum shall be necessary for the issuance of bonds under this Section.
The funds made available by the issuance of direct obligation or revenue bonds as herein provided shall constitute a Sanitary Fund, and shall be used for no other purpose than for carrying out such order or orders of the Board.
The Attorney General shall enforce this provision of the Act by an action for mandamus, injunction, or other appropriate relief.
Any general obligation bonds issued under this Section, or any revenue bonds issued under this Section as limited bonds pursuant to Section 15.01 of the Local Government Debt Reform Act, are subject to the requirements of the Bond Issue Notification Act.
