Wastewater

Optimise and overcome new challenges

The wastewater infrastructure in Switzerland is worth 125 billion Swiss francs. Nine hundred treatment plants clean the country’s wastewater around the clock. Part of the work of Eawag is to examine how this success story can be continuously optimised and tailored to suit the particular conditions in other countries, as well as to look at how to overcome new challenges

In the latest episode of the Papers to Practice Podcast, Dorothee Spuhler talks with Charles Niwagaba about his published article on the microbe-associated health risks involved in using faecal sludge in Ugandan agriculture. This is the second part of the podcast series, which she started with Laura Kohler.

The separation toilet save! has won the Design Award Switzerland 2021. This is also a milestone for Tove Larsen. She is a member of the Eawag Directorate and has been researching for almost 30 years how the nutrients in wastewater can be recovered in a useful way. In this interview on the occasion of World Toilet Day 2021, she explains how crucial our handling of wastewater is for climate change and for achieving the SDGs sustainability goals.

Selected research projects and focus areas

Application of Wastewater-based Epidemiology to SARS-CoV-2 Detection
Communities across the world face water supply challenges due to increasing demand, drought, groundwater depletion and contamination, dependence on single sources of supply, and ageing infrastructure
An inter- and transdisciplinary strategic research program that strives to develop novel non-gridconnected water and sani- tation systems that can function as comparable alternatives to network-based systems.
Eawag has a long history of developing innovative processes for separating wastewater at source. These technologies include one whereby urine is separated out using the NoMix Toilet.
We study the ecological stability of anammox biofilms, which are responsible for the autotrophic Nitrogen removal in mixed nitritation-anammox systems.
Sustainable urban water and wastewater management applied and implemented in the modular NEST building.
Greenhouse gas emissions from wastewater treatment
By recovering nutrients from urine, we develop a sanitation system, which produces a valuable fertiliser
Solid-Liquid Separation of Faecal Sludge: Understanding Governing Mechanisms for Improved Global Sanitation
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.
