S.D. Codified Laws § 46A-7-3
The board of directors may at any time call a special election and submit to the qualified electors of the district the question whether or not a special assessment shall be levied for the purpose of raising money to be applied for any of the purposes provided for in chapters 46A-4 to 46A-7, inclusive. The election shall be called upon the notice prescribed, and the election shall be held and the result of the election determined and declared in all respects in conformity with the provisions of chapters 46A-4 to 46A-7, inclusive. The notice shall specify the amount of money proposed to be raised, and the purpose for which it is intended to be raised. The ballots shall contain the words "Assessment--Yes," "Assessment--No." If a majority of the votes are "Assessment--Yes," the board shall, at the time of the annual levy, levy an assessment sufficient to raise the amount voted. The assessment shall be entered upon the assessment roll and upon the tax list by the county auditor and collected at the same time and in the same manner as other assessments. All revenue laws of this state for the collection of real estate taxes and sale of land for taxes apply to the assessment provided for in this section. When collected, the assessment shall be paid by the county treasurer to the district treasurer for the purpose specified in the notice of the special election.
