The board of directors of any water or sewer district organized under the provisions of chapter 32, title 42, Idaho Code, may at any time, on their own motion, call an election to submit to the qualified electors of a proposed water or sewer subdistrict the question of the creation of a water or sewer subdistrict. The election shall be called, held, and conducted pursuant to the provisions of chapter 32, title 42, Idaho Code. The proceedings calling the election shall set forth the boundaries of the proposed water or sewer subdistrict and shall provide for the submission of the question of the creation of the water or sewer subdistrict to the qualified electors residing within the proposed boundaries of the water or sewer subdistrict. No proposition for the creation of a water or sewer subdistrict shall be determined to have carried unless the proposition shall receive a majority of the votes cast. Whenever the creation of more than one (1) water or sewer subdistrict is submitted at the same election, separate ballots and separate propositions shall be used in voting on the question of creating each water or sewer subdistrict.
