(A) A separate and independent building sewer shall be provided for every building, except where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, driveway, or yard. The building sewer from the front building may be extended to the rear building and the whole considered one building sewer. The city does not and will not assume any obligation or responsibility for damage caused by or resulting from any such connection aforementioned.
(B) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Wastewater System Operator, to meet all requirements of this chapter.
(C) The size, slopes, alignment, and materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing, and backfilling of the trench shall all conform to the requirements of the state building and plumbing codes or other applicable rules and regulations of the city. In the absence of code provisions, or in the amplification thereof, the materials and procedures set forth in appropriate specifications of the ASTM and WPCF Manual of Practice No. 9 shall apply.
(D) 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.
