All surface runoff from areas expected to yield good quality water such as roofs, paved areas, lawns, and discharge from ground water collection systems must be excluded from the sanitary sewers. Basements shall be drained to the sanitary sewer because the wastewater from washing machines, portable laundry tubs, and shower baths can cause gross pollution of storm sewer outlets. Foundation drains are required to be discharged to a storm sewer. Unpolluted water from air-conditioning systems, industrial cooling operations, swimming pools, and the like shall be discharged to the storm sewers or directly to natural drainage outlets.
