Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In buildings in which the building drain is too low to permit gravity flow to the building sewer, the sanitary sewage carried by such building drain shall be lifted or gravity drained by a method approved by the Village Engineer to discharge the sewage to the building sewer.
