Department Sanitation, Water and Solid Waste for Development

Water Supply and Treatment

Sandec’s Water Suppy and Treatment (WST) group focuses on developing, testing and disseminating solutions for extending and sustaining access to safe drinking water globally. Our research approach draws on the fields of engineering, economics and the social sciences, with a specific focus on rural communities and small towns where progress towards international drinking water targets lags behind the rest of the world. As a WHO Collaborating Centre on Sanitation and Water in Developing Countries, we strived to link empirical evidence to sector policy and practice through targeted dissemination and open access training resources.
