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

What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine. New studies also show that the processes can be used not only for human urine, but also for that of cows or pigs.
