Department Urban Water Management

Urban Water Management

Research in this department aims at the urban water system as an entity and at developing the corresponding ecological, economical and social services into a sustainable future. In addition to traditional questions concerning urban hygiene and water pollution control, the sustainable use and management of the resources is a primary concern. Read more

Urban Water Observatory

The Urban Water Observatory (UWO) is a long-term initiative of ETH and Eawag to establish a sensor network in Fehraltorf, allowing spatially-distributed monitoring of urban water cycle processes.  Read more

With the latest analytical methods, potentially toxic substances can be detected even at very low concentrations. However, the aim of research is not merely to document such contamination but also to understand how it occurs in streams and groundwater, and to propose mitigation measures.

Research Projects

Goal is an improved planning procedure for sustainable water supply and wastewater infrastructure management that links into the existing Swiss governance structures.
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.
Kanalnetzbewirtschaftung für besseren Gewässerschutz
Application of Wastewater-based Epidemiology to SARS-CoV-2 Detection
In-Sewer LPWAN - A new LoRa-based synchronous mesh network to help monitoring in-sewer processes
Development of self-powered sensored pipes for smart management of water distribution systems
Improving the environmental benefits of green roofs through system focused experiments and modeling
The ‘Transitions Pathways Generator’ (TPG) model aims at the systematic generation of transition pathways describing technical adaptations of the urban drainage infrastructure.
