This report includes recommendations that will help the Hilton Foundation continue to strengthen and scale its impact and maintain its leadership through its investment in water projects and partnerships. The recommendations are derived from the findings of this assessment, combined with knowledge of the changing global and regional Water, Santiation and Hygiene context. The assessment and recommendations are timely as the Hilton Foundation works towards developing a new strategy and objectives.
