Since 1957 the Institute has provided graduate education to more than 15,000 water professionals from over 162 countries, the vast majority from the developing world. Numerous research and capacity development projects are carried out throughout the world. The Institute offers a unique combination of applied, scientific and participatory research in water engineering combined with natural sciences, social sciences and management and governance. Since its establishment the Institute has played an instrumental role in developing the capacities of water sector organizations in the Global South, not least by strengthening the efforts of other universities and research centres to increase the knowledge and skills of professionals working in the water sector.

IHE Delft carries out educational, research and institutional strengthening activities that complement and reinforce each other in the broad fields of water engineering, water management, environment, sanitation, and governance.
