Such petition shall be addressed to the board of supervisors of the county wherein it is filed and shall set forth:

 a. An intelligible description of the boundaries of the territory to be embraced in such district.
 b. The name of such proposed sanitary district.
 c. That the public health, comfort, convenience, or welfare will be promoted by the establishment of such sanitary district.
 d. The signatures of the petitioners.

 2. Territory shall not be included within more than one sanitary district organized under this chapter, and if any proposed sanitary district fails to receive a majority of votes cast at any election at which the establishment of the district is proposed as provided in this chapter, a petition shall not be filed for establishment of such a sanitary district within one year from the date of such previous election.
 3. a. There shall be filed with the petition a bond with sureties approved by the auditor, or a certified check, credit union certified share draft or cash in an amount sufficient for the payment of all costs and expenses incurred in the proceedings if the district is not finally established.

 b. No preliminary expense shall be incurred before the establishment of the proposed sanitary district by the board in excess of the amount of bond filed by the petitioners. In case it is necessary to incur any expense in addition to the amount of the bond, the board of supervisors shall require the filing of an additional security until the additional bond is filed in sufficient amount to cover the expense.
