I was watching the History International channel last night. They had a program discussing the ageing infrastructure of the US.

When talking about the sewer sytems, they said 900 billion gallons of sewer contaiminated water gets into the rivers/lakes/oceans every year. That is the equivelent of 21 days worth of water over the Niagra Falls.

If my math is correct, that would be like 9,000,000 gallons a year per power washer if we have 100,000 power washer in this country.

And they worry about us when we clean a side walk or wash a truck.
