Water resources

Resource availability and quality are becoming increasingly pressing issues as the global population and water consumption increase. Numerous countries and regions are already affected by shortages, and many others face recurring crises that the international community fears will deepen and become a source of conflict. Our activities include evaluating, mobilising and protecting water resources, and we have in-depth knowledge of hydraulics, hydrogeology, hydrology and geomorphology, which we apply in managing surface- and groundwater, designing tapping structures and preserving the quality of resources and environments.
