In addition to all other remedies, if a customer shall for any reason remain indebted to the Municipality for sewer service furnished, such amount due, together with any rents and charges in arrears shall be considered a delinquent sewer rent which is hereby declared to be a lien upon the real estate for which the same was furnished. The Municipal Clerk shall notify in writing or cause to be notified in writing, all owners of premises or their agents whenever their tenants or lessees are delinquent after the fifteenth (15th) of the month following the month in which service has been provided. If payment is not remitted within seven (7) days after the mailing of such notice, the Municipal Clerk shall certify the delinquent amounts to the County Clerk to be collected as a special tax in the manner provided by law.
