Building service sewer means a sewer pipe receiving flow from a single building, connecting to a sewer main or lateral and constructed on private property, except for a street crossing. A building service sewer shall preferably not exceed 120 feet and shall not, in any case, exceed 150 feet. If the length is exceeded, an intermediate manhole shall be built. A manhole or clean-out shall also be installed every 150 feet. When the building service sewer connects to a sewer lateral of a size not larger than the size of the service sewer, a manhole shall be built at the point of connection.
   Minimum design standards and other requirements, governing materials, joints, infiltration, workmanship and maintenance for sewer mains and laterals, shall also apply to building service sewers. Horizontal and vertical alignment of the service sewer shall be uniform and shall follow a straight line alignment. There shall be no dips in the grade or fall in the line. Turns or bends required for the riser, if any, or necessary to connect to the sewer wye or tee, shall be made with standard bends.
   In those instances where the building service sewer is partially constructed from the sewer lateral or main to a point other than the building to be served, the pipe shall be tightly plugged using a manufactured plug. The plug shall be pre-wired by the manufacturer so that it can be firmly secured in place.
