    Sec. 11-139-6. Within 10 days after the ordinance for any project under this Division 139 has been passed, it shall be published at least once in one or more newspapers published in the municipality, or, if no newspaper is published therein, then in one or more newspapers with a general circulation within the municipality. In municipalities with less than 500 population in which no newspaper is published, publication may instead be made by posting a notice in 3 prominent places within the municipality. The publication or posting of the ordinance shall be accompanied by a notice of (1) the specific number of voters required to sign a petition requesting the question of the adoption of the ordinance be submitted to the electors of the municipality; (2) the time in which such petition must be filed; and (3) the date of the prospective referendum. The municipal clerk shall provide a petition form to any individual requesting one. If no petition is filed with the municipal clerk, as provided in this section, within 30 days after the publication or posting of the ordinance, it shall be in effect. But if within this 30 day period a petition is filed with the municipal clerk signed by electors of the municipality numbering 10% or more of the number of registered voters in the municipality, asking that the question of acquiring, constructing, extending, or improving the combined waterworks and sewerage system, as provided in the ordinance, and the issuance of revenue bonds therefor be submitted to the electors of the municipality, the municipal clerk shall certify such question for submission at an election in accordance with the general election law. If a majority of the votes cast on the question are in favor thereof, the ordinance shall be in effect. But if a majority of the votes cast on the question are unfavorable, the municipality shall proceed no further and the ordinance shall not take effect.
