Car Washes
It is illegal to allow anything other than rain water to be discharged to a storm drain.
Never allow vehicle wash water, sealants, or other chemicals used to be transported to a street, gutter, parking lot, or storm drain. If discharged or disposed of improperly, materials such as hydrocarbons, oil and grease, and heavy metals can be harmful to water quality and creek habitats.
Individuals and businesses that improperly handle and dispose of non-stormwater materials down the storm drain are both subject to civil and criminal prosecution.
Cleaning products labeled “nontoxic” and “biodegradable” can still harm wildlife if they enter the storm drain system. These products are prohibited discharges to the storm drain system.
Best Practices:
Sweep the pavement where autos will be cleaned before you start.
Clean up wet or oily spots with rags and absorbent, or a designated mop.
Pour mop wash water into an inside drain.
Label storm drain inlets with simple messaging such as “No Dumping, Drains to Creek” with a clear picture or symbol.
Contain wash water and dispose of properly into the sewer system.
Properly contain used solvents for offsite removal.
If an automatic washer is being used, ensure that used water is self-contained in the unit and not allowed to discharge into the street or storm drain.
Inform Your Customers
Post signs to inform customers that working on vehicles is prohibited. It’s the law, call the Police if customers don’t comply.
