No. Only wastewater is collected and transported to the treatment plant by the sanitary sewer system. Stormwater flows through the storm sewer systems, ditches, and channels. It empties, untreated, into our streams, ponds, and lakes. It would be much too expensive to size the sanitary sewers and treatment plant to convey and treat stormwater in the same manner as sanitary sewage. The volume of wastewater generated by our homes and businesses each day is insignificant compared to the volume of stormwater runoff generated during a rainstorm. The better solution is to prevent the entry of pollutants into the stormwater system in the first place.
