Whenever the city council shall order any street, highway, avenue, alley, public ground or place permanently improved by paving, it shall be the duty of all owners of property fronting thereon to make the connections from sewers, gas lines, water lines, steam heating pipes and underground electric connections to the curbline of the adjacent property before the improvement is made.  In any case where any connection is not made before such improvement is made, no permit shall be issued for the making of any connection within fifteen months after such improvement is completed and accepted except upon payment of a fee of twenty-five dollars in addition to all other fees and charges, which fee shall be credited to the fund used in keeping pavements in repair.
