Arsenic Biosand Water Filter for Rural Nepal


 Project Description

dot.gif Objective:To provide potable drinking water in rural Nepal by installing a new type of household water filter, the Arsenic Biosand Filter (ABF), which removes arsenic and pathogens.
dot.gif Rationale:In Terai, the poorest rural region of Nepal, almost 40 percent of well water is contaminated by arsenic and pathogens. Villagers who drink the well water—estimated at 90 percent of the population—are susceptible to severe physical consequences, such as stunted growth and high cancer rates. A filter that is adaptable to local conditions to remove poisonous elements will improve the health of the entire region, reducing the incidence of water-borne disease and permanent physical deformities.
dot.gif Innovation / Expected Results:The ABF -- invented by engineers at MIT with the support of local partners -- provides simultaneous arsenic and pathogen removal for safe, clean drinking water. The safe, easy-to-use ABFs are constructed using local materials and labor, and demonstrate strong technical peformance, as well as high user acceptance. The project includes work with villagers to encourage long-term, self reliant safe water provision, involving 25 villages totaling 10,000 people.
