S.C. Code § 6-17-120
No recourse shall be had for the payment of the refunding bonds, or interest thereon, or any part thereof, against the general fund of any municipality, nor shall the credit or taxing power of any municipality be deemed to be pledged thereto.
The refunding bonds, and interest thereon, shall not be a debt of the municipality, nor a charge, lien or encumbrance, legal or equitable, upon any property of the municipality or upon any income, receipts or revenues of the municipality other than such of the revenues of the enterprise as shall have been pledged to the payment thereof, and every refunding bond shall recite in substance that such bond, including interest thereon, is payable solely from the revenues pledged to the payment thereof and that the municipality is under no obligation to pay the same, except from such revenues.
