Sewer pipes shall be run as directly as possible and shall have a fall of at least one-eighth inch to the foot. Where sewer pipe runs under a sidewalk, it shall be at least two feet below the sidewalk. Sewer and drains of greater depth than ten feet may run up to grade within three feet at the property line, and, where the property line is some distance above the grade of the street, one-eighth bends may be used. It shall not be necessary to lay sewer pipes deeper than two feet from the surface, provided a fall of one-eighth inch to the foot can be obtained.
