Water, Sanitation and Hygiene: Overview

Water, Sanitation and Hygiene

Water, sanitation and hygiene (WASH) are crucial building blocks for development. WASH interventions improve health outcomes, advance education, reduce poverty and malnutrition, increase child and maternal survival, drive economic growth, contribute to gender equality and dignity and improve overall quality of life. Despite the importance of WASH in virtually all development outcomes, an estimated 748 million people still lack access to safe drinking water, and 2.5 billion lack access to basic sanitation.


The InterAction WASH Working Group supports U.S. NGOs in advocating for the comprehensive integration of WASH into U.S. and multilateral development programs. If you are involved in WASH work, you can sign up for the WASH working group by first registering on this website and then requesting membership to the working group.
