The residual flow in the Sarine River is insufficient to maintain its dynamic flow. Research is currently being carried out as part of the “Energy Turnaround” National Research Programme (NRP 70), to ascertain whether hydropower can be made more environmentally friendly through controlled experimental flooding. The first experimental flood event has taken place, and researchers are now analysing all the data and records that have been collected. Read more

November 16, 2016

With the help of modern sensors and the innovative remote data transfer system LoRaWAN, researchers at Eawag are investigating the relationships between precipitation and the resulting drainage processes. It is hoped that the new technology, otherwise known as the “Internet of Things”, will enable wastewater disposal and sewage systems to be run as efficiently as possible, as well as allowing the quality of wastewater and waterbodies to be monitored.

The “Regional Water Supply for Basel-Landschaft 21” project, which was started in 2013, culminated today in a media conference in Liestal. Read more

100 Years of lake research in the Lucerne Nature Museum
November 14, 2016

A small exhibition in the Lucerne Nature Museum has been curated to commemorate the founding of the Hydrobiological Laboratory in Kastanienbaum 100 years ago in 1916. Visitors will also be able to view the exhibition “A Chance for the Otter”, which will be showing throughout the same period in the Forum Treppenhaus, as well as having the opportunity to learn about the early years of the Institute.

The theme of the recent Aqua Urbanica event, held on the Rigi by Eawag and the Swiss Water Association (VSA), was the importance of measurements. Read more

The wastewater treatment project in Asselda (Morocco) provides clean water for the inhabitants as well as for the irrigation of  fruit trees.
November 7, 2016

Eawag colleague Bouziane Outiti has been nominated for the 2016 Energy Globe World Award for his wastewater treatment project in Morocco. The award, which will be presented on 10 November at the World Climate Conference in Marrakech, is designed to highlight the existence of sustainable and innovative projects that tackle many of our environmental problems while protecting our resources.

Stream and river restoration measures may be showcase projects for conservationists, but – in the absence of systematic monitoring – it is often unclear what benefits they provide for ecosystems. Read more

On 1 November 1986, a chemical warehouse at Schweizerhalle near Basel was destroyed by a fire. Aquatic life in the Rhine suffered catastrophic damage as a result of inflows of toxic, red-coloured firefighting water. Read more

In the coming years, around a hundred wastewater treatment plants (WWTPs) across Switzerland are to be upgraded with an additional treatment step in order to eliminate micropollutants. The method of choice is often ozonation. Read more

Maldi-MSI imaging method visualises cocaine accumulation in zebrafish.
September 29, 2016

A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans. Read more
