Black plastic balls, which aim to reduce evaporation losses from open-air reservoirs under drought conditions, are not quite as efficient as previously assumed. Considerable quantities of water are already used in their production.  Read more

The CENTAUR sewer control system has been recognized as the ‘Most Innovative New Technology of the Year’ at the 2018 Water Industry Awards in England. CENTAUR stands for ‘Cost Effective Neural Technique for Alleviation of Urban Flood Risk’ and is funded by the European Union’s Horizon 2020 programme. Eawag researchers were part of this project.

Southerly countries are rich in genetic resources. The companies that exploit this natural treasure commercially are very often from the northern, developed world, however. The Nagoya Protocol was created in order to ensure fair use of genetic resources and appropriate compensation.  Read more

Microorganisms that live in symbiosis can sabotage biological methods of pest control by protecting their host from attackers, and host organisms can even pass on these beneficial “passengers” to their offspring. This phenomenon is one which has been paid little attention to date, but thanks to new research findings measures can now be taken to counteract it. Read more

What is the contribution of upstream areas to micropollutant loads in the Rhine at Basel and Düsseldorf? How effectively do authorities and water suppliers collaborate on management and regulation across national boundaries? An interdisciplinary approach developed by Eawag scientists can help to identify deficiencies. Read more

The elimination of aquatic environments of adequate size (here on the Doubs near la Motte / JU) is controversial in many areas (Photo: Foen, Ex-Press, Herbert Böhler & Flurin Bertsch).

In 2017, 68 cities (mostly in Europe) again took part in a large-scale project measuring drug levels in wastewater. The results for 2017 were published today by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).  Read more

Experimental flooding: Eawag researchers collecting data to improve the modelling of flash floods in urban areas. (Photo: Andreas Scheidegger, Eawag)

Heavy rainfall can cause flash floods in urban areas. While data from flood events is required to model such phenomena, water levels and discharges are not routinely measured above ground. Eawag now plans to make use of widely available images and videos to estimate these values. Read more

When a person wearing a bright-orange protective suit and carrying a laptop climbs out of a sewer shaft, it could well be an employee of the Swiss Federal Institute of Aquatic Science and Technology (Eawag). Especially if this happens in Fehraltorf. Since 2016, Eawag has been constructing an internationally unique net of sensors that document water circulation in residential areas. Read more
