(A) The installation of the building sewer and connection to the public sewer shall be made by a sewer and drain layer licensed by the city.
(B) The connection shall be made under the direct supervision of the City Engineer and in accordance with the following.
(1) Old building sewers. Old building sewers may be used in connection with new buildings only when they are found, on examination and test conducted by the owner and observed by the City Engineer, to meet all requirements of this subchapter.
(2) Separate building sewers. 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, yard or driveway. In those cases the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer, provided that the city shall require a written agreement between the property owners as to the share of the costs of construction and maintenance which each shall contribute.
(3) Connection. The connection of the building sewer into the public sewer shall conform to the requirements of Division 4, Plumbing Rules and Regulations, of the State Building Code, applicable rules and regulations of the city, or the procedures set forth in W.P.C.F. Manual of Practice No. 9 and the A.S.T.M. standards. All connections shall be made gastight and watertight. Any deviation from the prescribed procedures and materials must be approved by the City Engineer or a representative of the City Engineer before installation.
(4) Depth. Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. The depth of cover above the sewer shall be sufficient to afford protection from frost.
(5) Sewage lifts. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by the drain shall be lifted by approved artificial means and discharged to the building sewer.
