In the event charges for sewerage services are not paid within 60 days after the rendition of the bill for those services, the charges shall be declared to be delinquent and thereafter the delinquent charges shall constitute liens upon the real estate upon or for which sewerage services have been supplied. The City Clerk is hereby directed to file sworn statements showing these delinquencies in the office of the Recorder of Deeds of the county, which shall be deemed notice of the lien for payment of the sewerage service; provided, however, that the City Clerk may refrain from filing such a statement of delinquencies if the city proposes to sue or shall have sued the occupant or user of the real estate in a civil action to recover the delinquent charges.
