Lars is an Environmental Engineer, working with and for the sake of faecal sludge. Since 2012 I have been employed at Sandec (the Department of Water & Sanitation in Developing Countries) at Eawag (the Swiss Federal Institute of Aquatic Science and Technology) in Zurich, Switzerland. As part of my work I am getting to see many exciting places most people don't get access to. This Flickr site serves the purpose of providing you with insights into my work @Sandec.
