(A) 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 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 City Engineer. Where the public sewer is greater than 12 inches in diameter, and no properly located “Y” branch is available, the owner shall:
(1) Install a“Y” branch as heretofore specified; or
(2) Obtain entry by cutting a neat hole into the public sewer to receive the building sewer, either at the top for entry by means of a vertical riser or at the side with entry in the downstream direction at an angle of about 45 degrees. A bell and spigot section shall be used to make the (2) type connection, with the spigot end cut so as not to extend past the inner surface of the public sewer.
(B) (1) The invert of the building sewer at the point of connection shall be the same or at a higher elevation than the invert of the public sewer.
(2) A smooth, neat joint shall be made and the connection made secure and watertight by encasement in concrete.
(3) Special fittings may be used for the connection only when approved by the City Engineer.
