The storm drain system is designed to control the movement of rainwater. This aids in preventing flooding of streets, homes and businesses. The rainwater can pick up pollutants as large as shopping carts or as microscopic as chemical compounds and flush the contaminates into local waters, damaging aquatic life and marine ecosystems.
