This paper describes the World Bank DM2003 award, and the plan to implement the KAF (Kanchan Arsenic Filter) project throughout the Terai region in Nepal. The objectives of this project include the establishment of local entrepreneurs for a financially sustainable distribution mechanism, the capacity-building of local people towards long-term, user-participatory safe water provision, the dissemination of KAF information from a central technology centre, as well as networking with other water supply implementers.
