DID YOU KNOW: In San Antonio, stormwater does not drain into a sanitary sewer system. Stormwater flows directly into our creeks and rivers. Stormwater runoff is rainfall that has fallen onto hardened surfaces, such as streets, roofs, and driveways, picked up the various pollutants that are on those surfaces, and carried the pollutants into the storm drain and stream systems. Those pollutants include, but are not limited to, oil, fertilizers, bacteria, heavy metals, gasoline, and sediment.
