Extreme Water Salvage

I've written before about water independence and will surely write about it again, because I happen to feel that it is a very important topic.  It may not seem so to most, and indeed, if you feel comfortable and confident in the ability of the public water supply (and the distribution thereof which is completely dependent on a petroleum platform) then you have no need to worry about water independence.  If however, you are like me and are concerned that the petroleum industry and everything it supports are in their waning years, then you may want to spend some time pondering water filtration and rainwater harvesting.  Hence my project of the morning.
