No connections shall be made to a sanitary or to a combined sewer, which connections are intended to discharge inflow. Such prohibited connections include, but are not limited to, footing drains, roof leaders, roof drains, cellar drains, sump pumps, catch basins, uncontaminated cooling water discharges, or other sources of inflow.
For properties where separate storm sewers are available within 100 feet of the property line or where, in the judgment of the Superintendent, sufficient natural drainage is available, connections which contribute inflow to the sanitary sewers must be disconnected in a fashion approved by the Superintendent.
