ABSTRACT:
A method for collecting and treating small particulate pollutants typically found on the surface of streets in areas where the storm sewer and sanitary sewer are maintained separately. The method includes temporarily isolating a portion of the storm sewer in the immediate vicinity of the street to prevent any collected runoff from passing into the storm sewer, and then flushing the street with a stream of water to remove and collect the solid pollutants from the street surface. The flushing water containing the removed solid pollutants is collected and contained in the isolated storm sewer portion, and is then pumped into the sanitary sewer system for treatment in existing sewage treatment facilities.
