Stanford researchers are developing a range of promising solutions to water supply and access challenges that affect billions of people.


In many of the world’s overcrowded urban slums, residents must choose between open defecation, crowded public toilets or expensive private pit latrines that can't be emptied safely. A Stanford team working on a sustainable solution recently won a $15,000 grant from the U.S. Environmental Protection


Almost 3 billion people around the world use low quality sanitation facilities, or no facilities at all. Stanford's WHD program affiliates research the effectiveness of different policy and planning strategies designed to expand access to water and sanitation services worldwide.


A persistent challenge in the WASH sector is designing interventions--infrastructure investments, information campaigns, institutional innovations--whose benefits are sustained over the long term. WHD program affiliates explore different ways of operationalizing sustainability.


The links between water, sanitation, hygiene and health are intuitively obvious yet persistently challenging to document in a scientifically rigorous way. We work in the area of modeling health outcomes as a function of various water- and sanitation-related, socioeconomic and demographic factors.


Water supply and sanitation are linked to well-being not only through health, but through their impact on livelihoods and poverty. The WHD program researches the impacts of productive use and decentralized services of domestic water supplies and household waste.
