The Surface King is a mobile wash water recovery and recycling system that cleans an 8' wide path while driving, then recovers and recycles the wash water on board for reuse. We built it for a customer who needed to remove a soy-based paint used for event advertising. The system was shipped to France and used as part of the cleanup crew at the Tour de France.
The challenge: fast event cleanup without runoff
Painted road advertising has to come off quickly after the event, over long distances, without washing paint and wash water into storm drains. The customer needed to clean a wide path at driving speed, capture everything, and reuse the water, because a fresh water hookup wasn't available along the route.

How a closed-loop wash water recycling system works
- Wash. The pressure washers feed the 8' surface cleaning tool.
- Recover. The vacuum pulls wash water up through the tool as it moves.
- Separate. The Oil Harvester drops out solids and separates oils.
- Filter. Multi-media and cartridge filters polish the water.
- Reuse. Clean water returns to the holding tank and goes back through the pressure washers.
Who needs wash water recycling?
- Contractors working where water hookups are limited or discharge isn't allowed
- Municipal, event and street cleaning crews
- Fleet and equipment washers facing stormwater rules
