Billions of people lack access to safe, reliable, and affordable water, sanitation and hygiene (WASH) services. This has profound consequences for their health and welfare, especially for children. Conventional models for addressing this challenge, which focus narrowly on hardware installation of taps and toilets, often fail to deliver sustainable WASH services or to reach the people with the greatest need.

Osprey supports select WASH initiatives, NGOs, and social ventures with grants, impact investments, and expert advice on strategy, funding and operations. It focuses its WASH program in sub-Saharan Africa, Latin America and the Middle East.
