Biosand Filters

Biosand filters are an adaptation stemming from slow sand filters. It can be used as a simple household water treatment device. They consist of a plastic or concrete filter filled with sand and/or gravel. These filters are used to provide filtration to contaminated water sources.

What does this have to do with green empowerment? Just implementing these simple resources in developing nations help to stabilize the infant mortality rate. For instance, in Peru, with the help of biosand filters the infant mortality rate dropped to zero. Though it takes longer to develop, the positive effects are worth the long process.
