(A) The building sewer shall be constructed of concrete sewer pipe and fittings meeting the current A.S.T.M. specifications, extra strength concrete sewer pipe or poly-vinyl chloride SDR 26 plastic pipe. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe; except that, concrete pipe or plastic pipe may be accepted if laid on a suitable bed or cradle as approved by the inspector.
(B) All joints and connections shall be made gas tight and water tight. Poly-vinyl chloride SDR 26 plastic pipe shall bell and spigot, with spigot tapered to accept gasket joint. All PVC pipe joints shall be rubber gasket conforming to ASTM D-3212 and ASTM D1869. Lubricant shall be water soluble, non-toxic, and have no deteriorating effect on the PVC or rubber gaskets. The joints and connections shall conform to the manufacturer's recommendations.
(C) The size and slope of the building sewers shall be subject to the approval of the Inspector, but in no event shall the diameter be less than six inches; except that, for poly-vinyl chloride SDR 26 plastic pipe, the diameter shall not be less than four inches. The slope of the pipe shall not be less than one-eighth inch per foot, except as otherwise approved by the manager.
(D) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the inspector. Pipe laying and backfill shall be performed in accordance with current A.S.T.M. specifications; except that, no backfill shall be placed until the work has been inspected by the inspector.
(E) In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sewage carried by the drains shall be lifted by approved artificial means and discharged to the building sewer at the expense of the owner.
(F) The connection of the building sewer into the public sewer shall be made at the "Y" or "T" branch designated for that property, if the branch is available at a suitable location. Any connection not made at the designated "Y" or "T" branch in the public sewer main shall be made only as directed by the inspector.
(G) The applicant for the building sewer shall notify the inspector no less than 24 hours prior to the building sewer being ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the inspector or manager or his or her designee.
(H) All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard, streets, sidewalks, parkways and other public property disturbed in the course of work shall be restored in a manner satisfactory to the township.
