(A) There shall be two classes of building sewer permits:
(1) For residential and commercial service; and
(2) For service to establishments producing industrial wastes.
(B) 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, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer, but the city shall not assume any liability, obligation or responsibility for damage caused by or resulting from any such single connection.
(C) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Superintendent, to meet all requirements of this section.
(D) The size, slope, alignment and materials of construction of all sanitary sewers including building sewers, and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling trench, shall all conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the city, in the absence of which the provisions set forth in appropriate specifications of the A.S.T.M. and W.P.C.F. Manual of Practice No. 9 shall apply.
(E) 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 the building drain shall be lifted by an approved means and discharged to the building sewer.
(F) It is unlawful for any person to make connection of roof downspouts, foundation drains, areaway drains or other sources of surface runoff or groundwater to a building sewer, or building drain which in turn is connected directly or indirectly to a public sanitary sewer, unless the connection is approved by the Superintendent and the State Pollution Control Agency.
(G) All the connections shall be made gas-tight and water-tight and verified by proper testing. Any deviation from the prescribed procedures and materials must be approved by the Superintendent before installation.
(H) The applicant for a building sewer permit shall notify the Superintendent when the building sewer is ready for inspection and connection to the public sewer. The connection and testing shall be made under the supervision of the Superintendent.
(I) 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 the work shall be restored in a manner satisfactory to the city.
(J) Any new connection(s) to the sanitary sewer system shall be prohibited unless sufficient capacity is available in all downstream facilities including, but not limited to, the capacity for flow, BOD5 and suspended solids as determined by the Superintendent.
