Water and Development

WASH: water, sanitation and hygiene

Access to safe drinking water and sanitation are recognized in the Millennium Development Goals as key contributors to human health and welfare. Hygienic practices are also crucially important to prevent the spread of diarrheal disease, a major cause of childhood mortality. Appropriate management of excreta protects the environment and can allow for the recovery of nutrients and energy.

September 16, 2022The “Water Wall” developed by Eawag researchers recycles handwashing and toilet flushing water in a closed cycle and can therefore be used in regions with scarce water resources or those without water and wastewater networks. Now the project has been awarded the Mülheim Water Award.

August 4, 202225 years ago, urine-diverting toilets were no more than an idea, challenging the central paradigm of wastewater treatment plants. Since then, however, modular water technologies have become increasingly important. Using a new method, scientists at Eawag have mapped the dynamics of this transition.

Current research projects

Inadequate access to microbiologically safe drinking water continuously threatens the health and well-being of more than a billion people, primarily in developing countries
This project facilitates the exchange of data, maps and information on geogenic contaminants (focussing on arsenic and fluoride) via the web-based Groundwater Assessment Platform (GAP)
The aim of CWIS research is to develop a method that synthesizes existing information about the sanitation landscapes of cities in India and that presents comprehensive sanitation solutions.
With Helvetas-Nepal, this project aims to establish a drinking water security strategy in rural communities
Water Resource Quality (WRQ) was an integrated project running from 2006-2012 at Eawag that aimed to develop a generally applicable framework for the mitigation of geogenic contamination in groundwater used for drinking.
