Best Management Practices (BMPs)
If you are involved in the activities such as carpet cleaning, residential automobile repair and maintenance, landscaping activities and vegetation management, vehicle washing, pet waste, residential gardening and lawn care, the following is our recommended best management practices (BMPs).
King County Stormwater Pollution Prevention Manual
This manual has been adopted by the City of Des Moines and applies to all activities in Des Moines that have the potential to contribute pollutants to stormwater runoff or to receiving waters directly. Stormwater runoff may seep into the ground, drain to a storm drain or a drainage ditch, or flow over the ground. Regardless of the way runoff leaves the site, it can end up in a stream, river, lake, wetland, groundwater, or Puget Sound.
The manual includes stormwater BMPs for commercial, industrial, public, single family residential properties, multifamily residential activities, and information on how to implement many stormwater BMPs.

1. Options for Residential Car Washing
- Use a commercial car wash station
- Wash your car on gravel, grass, or other permeable surfaces
- Use hoses with nozzles that have automatically shut off when left unattended.
- Use a “Car Wash Kit” available free of charge to organizations that are fundraising. The kit is a storm drain insert and pump that captures soapy water runoff, allowing it to be pumped into sanitary sewage or vegetated area for treatment. See below for more information on how to check out a kit.
- Fundraising organizers can buy redeemable car wash ticket from Puget Sound Carwash Association at $2 and resale it at $5 to $8 without getting wet. For more detail visit The Green Car Wash Fundraiser website.
Request a Car Wash Kit
What runs off from your car goes right into storm drains and eventually into creeks, wetlands, and the Puget Sound. Please report any illicit activities! To request a car wash kit or report a spill please call Ben Stryker at (206) 870-6523 or email.
