Any user charges, connection fees, or other charges levied by any city, town or village shall be due at such time or times as specified by the governing board of the city, town or village and shall, if not paid by the due date, become delinquent and shall bear interest from the date of delinquency until paid. If such charges become delinquent they shall be a lien upon any land within the corporate limits of the city, town or village so charged, upon the governing board filing with the recorder of deeds in the county where the land is situated a notice of delinquency. The governing board shall file with the recorder of deeds a similar notice when the delinquent amounts, plus interest and any recording fees or attorneys' fees, have been paid in full. The lien hereby created may be enforced by suit or foreclosure.
