I know that camps recycle their water to different degrees, I found a blurb today on the Portland Chapter of Engineers without Borders (www.ewbportland.org/) site that refers to a promising cheap technology for water purification.

From an article published in the Newsletter for:
To Love Children Educational Foundation International, Inc.
www.tolovechildren.org
Crystal Clear Technologies has developed an affordable water purification system, which
successfully removes 99.999% of impurities from water. The technology uses a dirt-cheap zeolite
mineral, found globally. It is a natural molecular sieve, but it does not do everything, so we
designed chemical coatings that are synthesized from dirt-cheap compounds, and bonded them
onto the surface of the zeolite, thus modifying it. We can make the coatings to target certain
classes of contaminants.
This technology can be made in the country or nation that needs it, and can also be a source of
income. In addition, if made in-country, those who make it could control more aspects of clean
water availability. With privatization of nations’ water rights being traded for dollars from the IMF,
there will be serious and dire consequences down the road to the people who live in countries
most in need of water purification systems.
We are pursuing the viability of having Engineers Without Borders (EWB) set up the SMZ
manufacturing, with funding from IMF/World Bank money.
We look forward to partnering with To Love Children to bring our technology to Africa and to help
provide education concerning the importance of clean water, so that children can become
beneficiaries.
