Sewer rental charges remaining unpaid and delinquent shall constitute a lien upon the premises served and shall be certified by the Clerk to the County Auditor for collection in the same manner as property taxes; or, in the alternative, whenever a bill for sewer service remains unpaid and after due notice is served to the property owner, the Council shall certify to the County Auditor statement of lien claim. This statement shall contain the name of the owner of record, the legal description of the premises served, the amount of the unpaid bill, the date that the bill became due and payable, and a notice that the City claims a lien for this amount as well as for all charges subsequent to the period covered by the bill. The failure of the County Auditor to record such lien or to mail such notice or the failure of the owner to receive such notice shall not affect the right to foreclose the lien for unpaid bills as mentioned above.
