A sustainable water treatment system developed by AguaClara is delivering cheap drinking water to communities in Honduras using a power source far cheaper and more abundant than electricity: gravity.

In this podcast, AguaClara’s project coordinator Daniel Smith discusses his group’s project that provides potable water at less than .01 cent per liter, and uses simple and affordable materials available at the community level. Villages across Honduras are now drinking up and circumventing dependency on expensive and unreliable electricity sources to purify their water, thanks to AguaClara’s gravity-powered system.

Their innovation was recognized as a Tech Awards Intel Environmental Laureate for 2011, and AguaClara hopes to soon spread its impact beyond Honduras to neighboring countries like Nicaragua, Guatemala, and El Salvador.
