§ 51.042  ELEVATION OF BUILDING SEWER; GRAVITY FLOW TO SEWER.
   Where possible, the building sewer to serve a new building shall be brought to the building at an elevation below the basement floor.  The depth shall be sufficient to afford protection from frost and shall at a minimum be 42 inches from the ground level to the top of pipe.  Insofar as possible, the building sewer shall be laid at a uniform grade and in straight alignment.  Changes in direction shall be made only with properly curved pipe and fittings, unless the break in the line is made at a manhole facilitating servicing.  In all buildings in which the outlet from the lowest plumbing fixture is too low to provide gravity flow to the sewer, all sewage from such fixtures shall be lifted by approved mechanical means and discharged into the building sewer.  No water operated sewage ejector shall be used.
