(A) Materials and workmanship for building sewer construction shall meet the standards established by the city, as modified from time to time, or the applicable provisions of the current edition of the State Plumbing Regulations, and in conformance to the city sewer system regulations. Where in conflict, the more stringent standard shall apply. No backfill shall be placed until the City Inspector has inspected the work.
(B) There shall be a minimum horizontal separation of ten feet between water and sewer pipeline. In the event that this limitation cannot be met, the applicant will proceed only under special permit from the city, and under the direction of the City Inspector. When circumstances force the installer to cross potable waterlines and gas lines with sewer lines, the sewer lines shall be installed under the water or gas lines, and as nearly possible to a 90-degree angle. The bottom of the water piping at all points shall be at least 18 inches above the top of the sewer piping. Whenever the vertical separation between water and sewer lines is less than 18 inches, or if the water line is below the sewer line, either the water or the sewer line must be surrounded by encasement pipe.
