Detergents used while washing your vehicle can cause stormwater pollution. Use the following tips to reduce water usage and to reduce your impact on the environment.
- Wash your vehicle on a porous surface such as grass or landscaped areas. This reduces the amount of water discharged to the storm sewer system. Make sure not to wash your vehicle on surfaces without any ground cover (i.e. bare dirt) since this may discharge sediment to the storm sewer system which may violate local ordinances.
- Do not use harsh chemicals. Using degreasers, solvents, and other chemicals result in these materials discharging to the storm sewer system. Residues from these products can cause stormwater contamination.
- Wash your vehicle at a commercial car wash facility. Water from these facilities is plumbed into the sanitary sewer or recycled on site, not only preventing the discharge of pollutants, but saving water as well.
