Wash water originating from mobile washer activity is classified as industrial wastewater and must never be allowed to enter the storm drain. The wash water often carries with it pollutants such as suspended solids, oil and grease, heavy metals, hydrocarbons, and other organic matter. This discharge enters into our drainage system untreated eventually leading to our lakes, rivers, creeks and streams. The person who generates and releases such discharge may be held responsible for failing to observe these environmental regulations and City Ordinances.
This Fact Sheet provides Best Management Practices (BMPs) that are recommended for mobile washing units including but not limited to exterior building or house washing, sidewalk or parking lot cleaning, brick or stone restoration, wet sandblasting, environmental fleet washing, and graffiti removal.
