SDCL § 9-40-41: Drainage utility fund--Fees.

A governing body that establishes a flood or drainage control utility may adopt the same fee structure authorized for drainage basin utility districts in §§ 46A-10B-20, 46A-10B-21, and 46A-10B-22. Any fees collected pursuant to this section shall be placed in a special fund and may only be used to pay for new drainage improvements, maintenance of existing drainage improvements, and operation of the drainage utility. The provisions of §§ 46A-10B-24, 46A-10B-25, and 46A-10B-28 also apply to any fees collected by a municipality pursuant to this section.
