Many in India do not have access to clean drinking water, especially in rural areas. Our clean drinking water projects use bio-sand filters, a simple, affordable, environmentally friendly technology that is highly effective in removing pathogens. The technology was developed by David Manz at the University of Calgary.
In 2008, PPI partnered with Friendly Water for the World, in Olympia, WA to make bio-sand filters (BSF) available to villagers in Tamil Nadu. In the past 11 years, PPI has undertaken BSF projects with seven NGOs in five states. Bio-sand filters are manufactured locally and assembled on location. Villagers are trained in the use and maintenance of the filters. There is no recurring cost and a filter lasts the lifetime of the outer concrete container.
