When any street, alley, sidewalk or public ground has been cut into or opened, as provided in § 30-66, for the purpose of laying gas, water or sewer pipe or for any other purpose, the party doing the same shall puddle and ram the backfilling so as to prevent the settling of the place cut and the street shall be restored with similar material and workmanship to that existing in the street, alley, sidewalk or public ground before the same was torn up. All work shall be done to the satisfaction of the director of public works whose duty it shall be to inspect the same after it has been done. The work shall be completed or the opening refilled and replaced as herein provided and within the time specified in the permit.
