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, a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle at about 45 degrees. A 45-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, but no higher than a point one-half the vertical distance between the invert and the crown of the sewer. A smooth, neat joint shall be made, and the connection made secure and water-tight by encasement in concrete. Special fittings may be used for the connection only when approved by the City Engineer. Manholes shall be constructed at any junction of an eight-inch diameter line or larger into a public sewer.
