June 15, 2018The 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.

April 30, 2018There is a wealth of energy and nutrients in wastewater. New processes enable the recovery of these resources from wastewater and sewage sludge, with the goal of redefining the function of the wastewater-treatment plants. Formerly energy users, they will become energy producers and the source of valuable fertilizer. This new technology has convinced the Swiss Climate Cent Foundation. It is contributing financial support to the construction of the new installation in the ARA Altenrhein.

February 22, 2018The earth’s water supply is changing because of global warming: the ratio of precipitation to evaporation is sinking, and additional arid zones may emerge. The speed at which this development is likely to take place has been analysed by an international team including Eawag researchers.

February 19, 2018If the climate heats up, the temperature in the uppermost layer of lakes will increase, the thermic layering will become more stable and last longer, and less oxygen will reach the depths – this is the present theory on the effect of climate change on lakes.

February 15, 2018A shower hose will often contain more bacteria than the rest of the building’s plumbing system. A research team led by Frederik Hammes has been investigating this topic for the past four years. In their latest study, they analysed biofilms in 78 shower hoses from 11 countries, and in 21 of them, they detected legionella – a potential pathogen. In this interview, Hammes explains why we should not be unduly concerned.

February 12, 2018Heavy 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.

February 8, 2018When 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.
