During a car wash, dirty water containing soap and detergents, residues from exhaust fumes, gasoline and motor oils washes off the cars, flows off the pavement and into nearby storm drains (usually openings in the curb/gutter).
Unlike the water we use in our homes and businesses which is treated at wastewater treatment plants, the water that goes into storm drains flows directly into rivers, bays, oceans and lakes without any kind of treatment.
Alone, one car wash fundraiser event will create little, adverse environmental impact. But, collectively, car wash fundraiser events contribute significant amounts of water pollution.
To help ensure your compliance with municipal regulations, we suggest that you follow the "Good Housekeeping Practices" listed in the brochure for an environmentally successful car wash fundraising event.
