The Swiss Federal Institute for Aquatic Science and Technology (Eawag) is a Swiss Competence Centre for National and International Water Research. Multidisciplinary teams of specialists in the fields of Environmental Engineering, Natural and Social Sciences jointly develop solutions to water-related environmental problems. The Department of Water and Sanitation in Developing Countries (SANDEC), develops and implements new water and environmental sanitation concepts and technologies with partner organizations worldwide. Together with the multidisciplinary scientific and technological knowledge of EAWAG, it: (a) develops, provides and facilitates the implementation of new concepts and technologies in water supply and environmental sanitation; (b) increases research capacity and professional expertise in low and middle-income countries in the field of water supply and environmental sanitation; (c) raises awareness and enhances professional expertise in high-income countries in water supply and environmental sanitation of low and middle-income countries. With over 30 years of experience in the water and sanitation sector specifically related to low and middle income countries, Sandec has managed and carried out several research programs such as: solar water disinfection for household water treatment (SODIS); management and treatment options for faecal sludges from on-site sanitation, or; non-governmental solid waste collection systems and decentralized organic waste treatment options.

EAWAG was the main responsible for the assessment of sanitation technologies Work Package (WP3), participating in the evaluation of existing low cost conventional sanitation options and innovative sanitation technologies. Additionally, they gave their support in the definition of criteria for evaluation and systematisation of conventional and innovative low cost sanitation technologies (task 1.2) and contributed in the development of recommendations for future research and technology developments, among other tasks. Jointly with SEI, they also published at least one article concerning the WP3 (Sanitation Technologies Assessment).
