Wastewaters discharged from industrial and commercial establishments include process wastewaters containing organic or inorganic solids and cooling or condensing waters containing no added organic matter or reducing gases. Waters of the latter class, incapable of causing objectionable conditions in an open watercourse, shall be segregated from polluted wastes and discharged to storm sewers or to a natural outlet. Rainfall runoff shall not always be considered clean water but shall be routed according to its quality as per § 51.027. Even though unpolluted wastes do not increase the organic load on wastewater treatment units, the added volume increases pumping costs and reduces detention periods of settling tanks, and aeration units.
