Car Washing

What’s the Problem?

Car wash water contains road grime, oil and grease, heavy metals and soap. When you wash your car in your driveway or in the street, polluted wash water flows directly into the nearest storm drain. From the storm drain, this polluted runoff flows directly into our creeks, lakes and wetlands without treatment.

What Can We Do?

Wash your car at a commercial car wash: They are required to send polluted wash water to the sanitary sewer system, which cleans and treats water before it is discharged to Puget Sound. Most car washes also filter and reuse water several times before sending it to the sewer.

At home: If you wash your car at home, wash it on a grassy or gravel area, where the wash water will soak into the soil and won’t drain directly to a storm drain or local water body. Use chlorine and phosphate-free, biodegradable soap to wash your car. Even these soaps are harmful to aquatic life and water quality, so please use soap sparingly.

Planning a Fundraiser?

Try a green fundraising option: Community groups can raise money and be kind to the environment when choosing eco-friendly fundraisers.

Sending car wash runoff down the storm drain not only pollutes your lakes and creeks, it is also against the law (KMC 15.52.90). Although we try to educate first, you may face fines or penalties for repeat offenses.
