Living Water Intl is closely tied to my church community and on 10/10/11 they are launching a project to promote trading non-water drinking for water drinking for 10 days. After the 10 days, you give the money you would have spent ($30-$50) to help bring clean water to others in need. http://www.10days.cc/
If you want more details or where to send the money, msg me on facebook.
