When streets are opened for the purpose of making sewer connections, the pavement and the earth shall be deposited in the manner that will occasion the least inconvenience to the public and that will provide for the passage of water along the gutters.
The surface of the street pavement, flagging and gutters, after opening has been made for the purpose of sewer connections, must be restored to at least as good condition as before excavation, and the paving must be done by a competent paver. In refilling the trench, the same earth shall be replaced as was taken out; and in case of rock excavation, the trench shall be refilled with good earth.
Any person by whom any excavation is to be made for construction, altering or repairing a waste pipe or drain in any street in the City shall give notice, in writing, thereof to the City Engineer and to the owners of any pipes laid in the street about to be disturbed by such excavation at least 24 hours before the excavation is begun.
Any person disturbing pipes laid in the street shall, at his own expense, sustain, secure and protect such pipes from injury and shall pack the earth whenever the same shall have been removed, loosened or disturbed under or around such pipes so that the pipes shall be well and substantially supported.
