Rethinking wastewater management

An Eawag project in Bengaluru, India, is opening up new ways to respond to droughts and water scarcity. The focus is on the decentralised reuse of treated wastewater. Technological solutions alone cannot resolve the complex water challenges. Social aspects must be considered, as well. Read more

Eawag Info Day 2026: Energy - Water - Future
Tuesday, 8 September 2026, Swiss Museum of Transport Lucerne

The energy transition aims to move away from fossil fuels. This involves expanding renewable energy sources, including hydropower. However, hydropower is already highly developed in Switzerland, and in addition to the climate crisis - the primary driver of the energy transition - we are also facing a biodiversity crisis. Addressing both challenges simultaneously leads to conflicts that are particularly pronounced in water bodies. Net-zero strategies, the extraction of raw materials critical to the transition, and the use of geothermal energy can also impact water. Eawag’s research helps to make these conflicting goals transparent and enables the development of fact-based solutions. It provides policymakers with a basis for making ecologically,  economically, and socially sustainable decisions.
