No person shall install stub sewers in any public or private thoroughfare or right-of-way unless he is registered with the city pursuant to Section 13.52.210 and has complied with all of the requirements of this chapter. Any work on rights-of-way shall be in conformity with the requirements of the city. It will be the contractor's responsibility to notify the city representatives before beginning work on the right-of-way and to ascertain that the schedule of operation proposed is satisfactory to the city; provided, however, that all work must be completed with dispatch and in a reasonable time. If a contractor or owner has been notified by the city representative that certain work must be done and that person fails to do said work, the city may complete the work and charge the cost thereof to the person responsible.
