The WASHplus Project

The WASHplus project creates supportive environments for healthy households and communities by delivering high-impact interventions in water supply, sanitation, and hygiene (WASH) and indoor air pollution (IAP). WASHplus uses proven, at-scale interventions to reduce diarrheal diseases and acute respiratory infections, the two top killers of children under five years of age globally. WASHplus has expertise to integrate WASH and IAP activities into existing education, HIV/AIDS, maternal and child health, and nutrition programs. WASHplus builds strong in-country partnerships to increase impact. In addition, WASHplus is charged with exploring and promoting innovation in the WASH and IAP sectors. WASHplus is funded by the United States Agency for International Development's Bureau for Global Health.
