(A) The size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, joint testing and backfilling the trench shall all conform to the requirements of the building and plumbing code or other applicable rules and regulations of the village. In the absence of code provisions or in amplification thereof, the materials and procedures shall comply with the specifications of the ASCE Manuals and Reports on Engineering Practice No. 60 WEF Manual of Practice No. FD-5.
(B) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer.
(C) No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, sump pumps or other sources of surface run-off or ground water to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
(D) All exterior sanitary sewer pipes shall be constructed of six-inch pipe, or larger where applicable, of gasketed polyvinyl chloride (PVC) SDR 35 pipe. Solvent-weld pipe shall not be permitted. Sewers must have a gradual fall of not less than one foot per 100 feet of length, or one-eighth inch per foot, with no sharp breaks in grade. Changes in direction must be made with 22° or 45° fittings or wyes. Ninety degree fittings are only permitted where a service lateral makes a vertical drop. Sewer pipes shall be bedded and backfilled to a minimum of 12 inches above the top elevation of the sewer with #8, #57, or #67 stone or gravel.
(1) Sewer excavations made within the paved area of any street, road, driveway, or under any area where a sidewalk will be constructed, shall be backfilled to the bottom edge of any existing pavement or sidewalk with either #57 stone, or compacted #304 stone. Any street excavation that will not be immediately paved over shall be topped off with a minimum of three inches of compacted #411 stone or gravel, or a minimum of three inches of compacted cold mix asphalt.
(2) No sanitary sewer shall be constructed within ten feet of any potable water line. If a sanitary sewer must cross a potable water line, the sewer shall cross under the water line with a minimum of 18 inches of clearance. All sanitary sewers shall be installed to maintain a minimum five-foot distance from any other public or private utility, and at no time shall any other utility, either private or publicly owned, share or be installed in the same trench as a sanitary sewer.
(E) Inspection openings (clean-outs) shall be installed within ten feet of the edge of the building served, and every 100 feet thereafter. Inspection openings shall consist of a six-inch diameter straight tee, clean-out tee, or a two-way clean-out. Four-inch inspection openings are permitted, but only within ten feet of the building served. Wyes shall not be used for inspection openings. Inspection openings shall be topped with a threaded clean-out plug and shall terminate at or just below finished grade. Inspection openings installed within a paved or gravel driving surface shall be topped with an approved cast-iron clean-out cover.
