Except as provided in Chapter 1042, all new sewer construction shall provide two separate and distinct sewerage systems as follows:
(a) Storm Sewerage System. This system shall be for the collection and conveyance of surface run-off and other storm waters. All storm waters shall be collected and conveyed in a pipe or ditch system to the point of discharge in the receiving natural or man-made stream or drainage ditch. No storm waters shall be permitted to enter the sanitary sewerage system, except that in combined sewer areas storm waters may be discharged into Metropolitan Sanitary District interceptors.
(b) Sanitary Sewerage System. This system shall be for the collection and conveyance of sanitary sewage consisting of domestic and other water-borne wastes. All sanitary sewage shall be collected and conveyed in a pipe system to the point of discharge into an existing sanitary sewerage system, MSD interceptor or treatment plant. No sanitary sewage shall be permitted to enter any storm sewerage system or discharge onto the ground or into receiving streams without first having been treated.
