Water Supply and Treatment

Sandec’s Water Supply and Treatment (WST) group focuses on developing, testing and disseminating solutions for extending and sustaining access to safe drinking water supplies. We use methods from the fields of engineering, public health, and social psychology, with emphasis on applicable solutions for rural communities and small towns where  progress towards international drinking water targets lags behind the rest of the world. Current projects focus on passive chlorination technologies, rural lab strengthening, and assessing integrated planning approaches.
