All interested persons, officials, residents, voters, taxpayers, property owners or other persons or corporations in any way affected by the granting of the petition shall be heard on any question dealing with the location of the boundaries of the district. Such notice shall contain a description of the boundaries of the proposed sanitary district and if the public hearing is ordered as a result of the filing of a petition such boundaries shall be those described in the petition.
