Frequently Asked Questions (FAQ)

Where can a mobile car wash business recycle waste water?

Mobile car washers must either pretreat the wash water to remove oil and solids before discharge into a sewer cleanout or haul the water to a wastewater treatment facility or have an agreement with a car wash to discharge the waste waster into their clarifier. Either way, an industrial waste permit is required. Once the permit is issued, the mobile car washer must document the locations they are washing, disposal dates, and gallons of wastewater and submit the self-monitoring report on a quarterly basis. Please contact LA County Dept of Public Works Environmental Programs Division at 626-458-3517 on how to obtain a permit.
