That's a good idea.
I saw some show about purifying water in these countries, and it turns out that if you take the uncleaned water and set it on the roof of your hovel in the normal plastic water bottles, something about the heat and UV rays or whatever kills all the bad stuff in the water. I suspect you know far more about that than I'm conveying, but I thought it was a bizarrely simple solution.
