(A) 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.
(B) Existing sewers may be used in connection with new construction when they are found on examination and test by the Inspector to meet all requirements of this chapter.
(C) The building sewer shall be cast iron soil pipe, A.S.T.M. specification or equal; vitrified clay sewer pipe, A.S.T.M. specification or equal; or other suitable material approved by the Inspector. Joints shall be tight and waterproof. Any part of the building sewer that is located within ten feet of a water service pipe shall be constructed of cast iron soil pipe with leaded joints. Cast iron pipes with leaded joints may be required by the Inspector where the building sewer is exposed to damage by tree roots. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except that nonmetallic material maybe accepted if laid on a suitable concrete bed or cradle as approved by the Inspector.
(D) The connection of the building sewer into the public sewer shall be made by the “Y” branch, if such branch is available at a suitable location. If the public sewer is 12 inches in diameter or less, and no properly located “Y” branch is available, the owner shall at his or her expense install a “Y” branch in the public sewer at the location specified by the Inspector. Where the public sewer is greater than 12 inches in diameter, and no properly located “Y” branch is available, a saddle type fitting may be cut in the public sewer to receive the building sewer, with entry in the downstream direction of an angle of about 45 degrees. A 45-degree elbow may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or at a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made, and the connection made secure and watertight by encasement in concrete. Fittings may be used for the connection only when approved by the Inspector.
(E) The owner (or the owner’s contractor or legal representative) seeking to connect to the city’s sewer shall notify the Inspector when the building’s sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Inspector or his or her representative.
(F) 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. The property owner shall be responsible for any necessary permits.
(G) The Columbia City Water Pollution Control Facility has adopted certain specifications and requirements for construction and installation of sanitary sewer mains and lift stations for the city sanitary sewer system. These specifications, as may be modified or amended from time to time, are hereby adopted by reference into this chapter.
