Auto Detailers

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.

Best Practices:

  • Sweep the pavement where autos will be cleaned before you start.
  • Contain wash water and dispose of properly into the sewer system.
  • Temporarily block the storm drain inlet.
  • Use a berm to collect any discharge.
  • Use a specially designed mobile wash pad/containment pool.
  • Do a final rinse of any wet pavement with clean water. Make sure this water is collected.

Wastewater Requirements

An approved oil/water separator is required for engine cleaning wash water. A Wastewater Discharge Permit may be required. Check with your local municipality for specific requirements.
