For more than 25 years, the Conrad N. Hilton Foundation has been committed to improving access to safe drinking water in low-resource settings of Sub-Saharan Africa, Mexico and India. Our investments in the water sector have been guided by global ambitions, beginning first with the call to eradicate guinea worm followed by the Millennium Development Goals’ (MDGs) drinking water target. The adoption of Sustainable Development Goal 6 (SDG 6) gives the Water, Sanitation and Hygiene (WASH) sector a new global ambition to strive for – pushing for bigger and better services. The Foundation has embraced this bold challenge with the design and release of its 2017-2021 grantmaking strategy.
