   (b)   Classes of Permits. There shall be three classes of building sewer permits: for residential; for commercial service; and for service to establishments producing industrial wastes. In either case, the owner or his agent shall make application on a special form furnished by the City. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Sanitary Board. A permit and inspection fee of ten dollars ($10.00) for a residential building sewer permit, ten dollars ($10.00) for a commercial building sewer permit and twenty-five dollars ($25.00) for an industrial building sewer permit shall be paid to the City Treasurer at the time the application is filed.
   (c)   Cost of Installation. All costs and expense incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the City from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
   (d)   Separate Connection Each Building. 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.
   (e)   Old Sewers, Reuse. Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the City, to meet all requirements of this article.

In the absence of Code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the A.S.T.M. and W.P.C.F. Manual of Practice No. 9 shall apply.
   (g)   Elevation. 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.
   (h)   Surface Water Drainage. No person shall make connection of roof downspouts, exterior foundation drains or other sources of surface runoff or ground water to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.

The connection of the building sewer into the public sewer shall conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the City, or the procedures set forth in appropriate specifications of the A.S.T.M. and the W.P.C.F. Manual of Practice No. 9. All such connections shall be made gastight and watertight.
   (j)   Deviations, Approval. Any deviation from the prescribed procedures and materials must be approved by the Sanitary Board before installation.

   (l)   Excavations. All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard.
