Stormwater runoff is not treated and is the leading source of water pollution in our community. Runoff flows directly from the storm drain into local creeks and rivers. Water and soap that goes down a storm drain is not treated. Even mop water should go down a utility sink drain.
To keep soap and other chemicals out of our stormwater, use a professional carwash. Dispose of mop water down a utility sink attached to a sanitary sewer.
