In the event any person, firm, corporation, political unit (except the United States and the state of Kansas) or organization living or operating on premises connected to a sanitary sewer shall neglect, fail or refuse to pay the service charge fixed by the governing body for the operation of the sewage disposal system, such charges shall constitute a lien upon the real estate served by the connection to the sewer, and shall be certified by the city clerk to the county clerk to be placed on the tax roll for collection, subject to the same penalties and collected in like manner as other taxes are by law collectible, and the governing body shall have the right to refuse the delivery of water through the pipes and mains of its waterworks system until such time as such charges are fully paid. (Prior code § 9-406)
