A.    It is unlawful for any person to place, deposit or permit to be deposited in an unsanitary manner upon public or private property within the city of Columbus, Indiana, or in any area under the jurisdiction of the city, any human or animal excrement, garbage or other objectionable waste.

    B.    It is unlawful to discharge to any natural outlet within the city, or in any area under the jurisdiction of the city, any sanitary sewage, industrial waste or other polluted waters, except where suitable treatment has been provided in accordance with subsequent provisions of this chapter.

    C.    No person shall place, deposit or permit to be deposited in any unsanitary manner on public or private property within the jurisdiction of the city, any wastewater or other polluted waters except where suitable treatment has been provided in accordance with provisions of this chapter and the NPDES permit.

    D.    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 director.

    E.    There shall be two classes of building sewer permits: (1) for residential and commercial service and (2) for service to establishments producing industrial waste. In either case, the owner or his agent shall make application on a special form furnished by the city sewage works. The permit applications shall be supplemented by any plan, specifications or other information considered pertinent in the judgment of the director. A permit and inspection fee of fifteen dollars for a residential or commercial building sewer permit and forty-five dollars for an industrial building sewer permit shall be paid at the time the application is filed to the city sewage works.

    F.    All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner or the person installing the building sewer for the owner shall indemnify the city from any loss or damage that may directly or indirectly be occasioned by such installation. The city may require adequate proof of financial responsibility before issuing a building sewer permit.

    G.    A separate and independent building sewer shall be provided for every building; except where two buildings are in close proximity and no private sewer is available or can be constructed to the second building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the second building and the whole considered as one building sewer.

    H.    Old building sewers may be used in connection with new buildings only when they are found on examination and tested by the director to meet all requirements of this chapter.

    I.    The building sewer shall comply in material and workmanship to all requirements of the Indiana Plumbing Code of Current Adoption (Title 675).

    J.    The size and slope of the building sewers shall be subject to the approval of the director, but in no event shall the diameter be less than four inches for single-family or duplex residential units and not less than six inches for all other uses. The slope of such four inch pipe shall be not less than one-fourth inch per foot or sufficient slope to maintain a two feet per second velocity in the sewer.

    K.    No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at a uniform grade and in straight alignment in so far as possible. Changes in direction shall be made only with properly curved pipes and fittings.

    L.    In all buildings in which any building drain is too low to permit gravity flow to the public sewer, or gravity sewers are not available, sanitary sewage carried by such drains shall be lifted by approved artificial means and discharged to the building sewer. The director shall approve all such devices prior to installation. No water operated sewage ejector shall be used.

    M.    All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the director. Pipe laying and backfill shall be performed in accordance with ASTM specifications and Indiana Plumbing Code, except that no backfill shall be placed until the work has been inspected by the director.

    N.    All joints and connections shall be made gas tight and watertight, and as governed by the Indiana Plumbing Code in effect as of the date of adoption of this chapter, and any provisions thereof which may be amendatory thereof or supplemental thereto from time to time hereafter.

    O.    The connection of the building sewer into the public sewer shall be made at the "Y" branch, if such branch is available at a suitable location. If the public sewer does not have a properly located "Y" branch, the owner shall at his expense install an approved tapping saddle in the public sewer at the location specified by the director. The tapping saddle shall be installed in a neatly tapped hole cut into the public sewer; the connection between the tapping saddle and public sewer shall be secured by the use of epoxy compound. The center line of the building sewer at the tapping saddle shall be at or above the center line of the public sewer. A smooth, neat joint shall be made, and the connection made secure and watertight. Special fittings may be used for the connection only when approved by the director.

    1.    House connection laterals will be provided under the rules of 40 CFR 402 where public sewers are separated from property lines by adjacent public rights-of-way. Once the building sewer is connected to these lines, the entire line is considered as a building sewer to its connection point with the primary sewer and is the maintenance responsibility of the property owner.

    P.    The applicant for the building sewer permit shall notify the director at least one business day in advance of when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the director or his representative.

    Q.    All excavations for building sewer installation shall comply to all other local ordinances and procedures for work within the public right-of-way.

    R.    No person shall discharge or cause to be discharged any storm water, surface water, ground water, artesian well water, roof runoff, subsurface, condensate, to any sanitary sewer, unless authorized by the director.

    S.    Storm water and all other unpolluted waters shall be discharged to such sewers as are specifically designated as storm sewer, or to a natural outlet approved by proper authorities. (Ord. 99-16 (part), 1999)
