Water for humans

Eawag researches and tests technologies and strategies that enable society to use water sustainably. A safe drinking water supply and optimised wastewater treatment not only benefit human health, but also protect the environment.

Sustainable water management means that sufficient clean water is available when and where it is needed – for example in the form of drinking water, for food production or sanitation purposes – and ensures that wastewater is purified in the best possible way. It also means that available resources are not over-exploited, the integrity of ecosystems is protected, the costs are affordable to society, and the system as a whole is able to respond flexibly to challenges whilst at the same time having inherent stability. That is the ideal. The reality is somewhat different in many places: new pollution from ever-increasing numbers of problematic substances, more frequent droughts and heavy rainfall due to climate change, conflicts between different stakeholder groups and the loss of important nutrients from regional cycles are just a few examples. Eawag’s research addresses these challenges.
