The connection of the building sewer into the public sewer shall be made in the following manner:
(A) If the diameter of the building sewer is equal to the diameter of the public sewer, connection shall be made at a wye branch in the public sewer at a location specified by the General Manager.
(B) When the diameter of the building sewer is less than the diameter of the public sewer and no properly located wye branch is available, a cored hole may be cut into the public sewer to receive the building sewer and shall be fitted with a special saddle connection. The saddle connection shall be equipped with complete annular shoulder to prevent it from slipping into the inner surface of the public sewer and a neoprene seal to make a watertight connection. The saddle adapter shall be securely fastened in place by a minimum of two stainless steel bands.
(C) Other special fittings may be used for connection only when approved by the General Manager.
(D) The top of the pipe of the building sewer at the point of connection shall be at the same or at a higher elevation than the top of pipe of the public sewer.
(E) The portion of the building sewer in the street shall be at right angles to the right-of-way lines and at least two and one-half feet below the gutter flow line grade. When the building sewer is less than two and one-half feet below the gutter flow line grade, the same must be covered with at least six inches of concrete to protect the same from breakage, or shall be of cast or ductile iron pipe.
(F) The applicant for the building sewer permit shall notify the General Manager when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the General Manager.
