(A) When branch sewer connections are made to a manhole, the branch line must be connected at the bench wall level. The bench wall shall be channeled in such a manner as to direct the incoming flow to the outlet pipe.
(B) However, if the main sewer is three feet or more below the branch sewer, the branch sewer connection shall be made with a drop connection, in accordance with the city's standards unless a specific variance is granted by the engineer.
