(A) The size, slope, alignment, and materials of construction of a building sewer, and the methods to be used in excavation, placing of the pipe, jointing, testing, and backfilling the trench, shall all conform to the requirements of the Building and Plumbing Codes or other applicable rules and regulations of the village. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the American Society of Testing Materials, Water Pollution Control Federation Manual of Practice No. 9, and Standard Specifications for Water and Sewer Main Construction in Illinois shall apply.
(B) 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 the frost. The building sewer shall be laid at uniform grade.
(C) Any sewer connected shall be laid as nearly as possible in a straight line. All changes in direction shall be made with properly curved pipe or at manholes.
(D) The slope of the building sewer shall be subject to the approval of the Superintendent but not less than one-eighth inch per foot nor more than one-half inch per foot.
(E) The building sewer shall be four-inch cast iron soil pipe, approved PVC, or other suitable material approved by the Superintendent. Any part of the building sewer that is located within two feet of a water service pipe or within 50 feet of a well shall be constructed with cast iron soil pipe with leaded joints or watertight rubber ring joints. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except that nonmetallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the Superintendent.
(F) All joints and connections shall be made gastight, watertight, and root-proof.
(G) All joints between such pipes and metals shall be made with approved premoulded rubber, polyvinyl, or polyester joints.
(H) Material for joints shall not soften so as to destroy the effectiveness of the joint when subjected to a temperature of 160°F., nor be soluble in any of the wastes carried by the drainage system. Other jointing materials and methods may be used only upon approval of the Superintendent.
(I) The interior of the sewer shall, as the work progresses, be cleaned of dirt, joint compound, and superfluous materials of every description.
(J) The connection of the building sewer into the public sewer shall be made at the "Y" branch or "T" is such branch is available at a suitable location. If the public sewer is 12 inches in diameter or less and no properly located "Y" branch or "T" is available, the owner shall at his expense install a "Y" branch in the public sewer at the location specified by the Superintendent. Where the public sewer is greater than 12 inches in diameter and no properly located "Y" branch is available, a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about 45 degrees. A 45-degree ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made and the connection made secure and watertight by encasement in concrete. Special fittings may be used for the connection only when approved by the Superintendent.
(K) Unless otherwise directed, all sewer and water trenches and excavations shall not be backfilled until inspected and approved by the Superintendent or his representative as herein provided, and all work approved.
