S.D. Codified Laws § 11-7-105
Neither the commissioners of a commission nor any person executing the bonds is liable personally on the bonds by reason of the issuance of the bonds. The bonds and other obligations of a commission (and such bonds and obligations shall so state on their face) are not a debt of the first or second class municipality, the state, or any other political subdivision of the state and neither the municipality nor the state or any other political subdivision is liable for the bonds. Except as may be provided pursuant to subdivision 11-7A-2(8), the bonds or obligations are not payable out of any funds or properties other than those of the commission. The bonds do not constitute an indebtedness within the meaning of any constitutional or statutory debt limitation or restriction.
