If the owner of a lot or parcel of land does connect a building used for either residential, commercial or industrial purpose or a trailer used as a dwelling to the municipal sewer system within the 60-day period of time as provided in section 78-27, the city shall make no hookup or connection charge. However, if such connection is not made within the 60-day period, a charge in the amount set forth in appendix B to this code shall be assessed against such owner by the city as a penalty for failure to comply with this section within the 60-day period of time. Where sewer lines are installed by subdivision, such hookup penalty shall not apply. In addition and as an alternative means of collecting such late connection penalty, the city shall have a lien on such lot or parcel of land for which such lien shall be equal in dignity with the lien of state and county and municipal taxes. Such lien may be foreclosed by the city in the same manner provided by state law for the foreclosure of mortgages upon real estate.
