(a)    No unauthorized person shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the Superintendent.
   (b)    There shall be two classes of building sewer permits: (1) for residential and commercial service, and (2) 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 Superintendent. A permit and inspection fee for either type sewer permit shall be paid to the City at the time the application is filed.
   (c)    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)    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 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 chapter.
   (f)    The size, slope, alignment, materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench, shall conform to the requirements of Section 937.10(a). In the absence of provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the Ohio Environmental Protection Agency, the ASTM and WPCF manual of practice No. 9 shall apply.
   (g)    Whenever possible, the building sewer shall be brought to the buildings at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity to 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)    No person shall make connection of roof downspouts, exterior or interior foundation drains, sump pumps connected to foundation drains, areaway drains, loading dock drains, or other sources of surface runoff or groundwater to a building sewer or building drain which is in turn connected directly or indirectly to a public sanitary sewer.
   (i)    The connection of the building sewer into an existing public sewer shall be made with a forty-five degree angle pointing downstream. Two forty-five degree els may be used to make a long ninety degree angle thereby allowing a shorter run of building sewer pipe. The connection to the main sewer pipe shall be made with an approved cast iron connector and made watertight and strong by encasing in concrete for a distance of six inches in all directions from outer edge of tap.
   (j)    The connections for building sewers shall be provided for when new sewer main is installed by installing forty-five degree wyes for each lot. When new streets are involved, the building sewer shall be installed to each lot line and tested with the main sewer.
   (k)    All building sewer connections are to be recorded as to distance to downstream manhole. Lot line connections to be recorded by triangulation from both downstream and upstream manholes and marked with a two inch by four inch piece of wood extending from the end of pipe to not less than one inch above final grade of lot.
   (l)   All new or repaired old building sewer pipe shall have a cleanout installed using either a large side outlet tee or two wyes facing each other so the sewer may be cleaned either way. Also a cleanout connection at the opposite side of the building or in the basement may serve as a cleanout. The cleanout must be strong and water and airtight. If installed in yard, the connections must be set in concrete.
   (m)    The applicant for the building sewer permit shall notify the Superintendent twenty-four hours before the building sewer is ready for inspection and connection to the public sewer. The connection shall be made during normal working hours of the City Sewer Department and under the supervision of the Superintendent or his representative.
   (n)    All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazards. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the City.
   (o)    All building sewers shall be properly maintained by the property owner at no
expense to the City. If the building sewer becomes in need of repair to the point that the sewage system is affected, the Superintendent, upon notice to the property owner may make necessary repairs to such sewer and bill the owner for same.
   (p)    Where the building sewer is suspended across a lower ditch such as the area around a basement wall, either cast iron or asbestos-cement pipe must be used to bridge the open space.
