About
CAWST, the Centre for Affordable Water and Sanitation Technology, is a non-profit organization that provides training and consulting to organizations that work directly with populations in developing countries who lack access to clean water and basic sanitation.
CAWST walks alongside hundreds of organizations—government agencies, community groups, and local and international NGOs of all sizes—in 101 countries as they develop their capacities to deliver water and sanitation programs locally.
CAWST has convincingly demonstrated its ability to catalyze community action in developing countries to initiate and operate water and sanitation programs for those who live without.
