What if we can wash equipment, buildings, sidewalks and reuse all the water over and over again? Why would we need to do this you ask? Well consider the muddy mess in Beijing after the mighty sand storm put a layer of sand everywhere and filled the skies making air-quality so bad no one could breath.
Next consider that they had to seed clouds to get it to rain in order to clear the air. Next the ground is a muddy mess and must be power washed by thousands of pressure washers, water trucks and mobile units. But wait, we need to conserve the water too? Oh now you see the need for such a system? Well such systems capable of doing this do exist. For instance I have heard of run off water being used like this in the cleaning of Military Equipment, Trucks and Aircraft. For instance Kellogg, Brown and Root uses such a system in Kuwait to save the expensive water. I believe they are either using a "Landa Water Maze" (Landa in WA or the Karcher equivalent (German Company). There is another company in the States, which makes these too and Hydrotech in Riverside, CA has a similar unit they buy thru their vendor and modify from Coastal CA.
There are many smaller companies who make such things for run off from construction sites and remediation of things like well, like the cleanup after Major Mother Nature Issues, Debris, flooding, etc, even Hurricanes. So it is possible to clean up Beijing with thousands of pressure washers in a few days without running out of water supplies, so consider all this in 2006.
