This is an introduction to the biosand filter that Globalize This uses. It's an adaptation of the classic concrete biosand filter that uses a 55 gallon plastic barrel instead, which is locally available here in Mexico. Also, not only is it useful in humanitarian situations, but biosand filtration is also a good idea for anyone who is interested in knowing how to filter their own water in case their is a failure in the city's water supply
