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 is twelve inches in diameter or less, and no properly located "Y" branch is available, the owner shall, at his expense, install a "Y" branch in the public sewer at the location specified by the Superintendent. Where the public sewer is greater than twelve inches in diameter, and no properly located "Y" branch is available, a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about forty-five degrees. A forty-five degree ell 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. Special fittings may be used for the connection only when approved by the Superintendent.
All new installations of sanitary sewers shall be brought to the property line of the owner and at this point the property owner shall install an inspection and cleaning tee. This tee shall be no less than six inches in diameter, inside, shall be brought to between four and six inches to top of grade and a sufficient metal cap shall be installed.
