TRansitions to the Urban Water Services of Tomorrow (TRUST) is a integrated research project funded by the European Union. Over the course of four years and driven by the need of transformation and the wish to protect natural resources, 30 partners in eleven different countries will research innovations and tools to create a more sustainable water future. The results will be implemented and tested in nine participating different pilot cities or regions, grouped in green cities, water scarcity regions and urban/peri-urban metropolitan areas. All the information and products resulting from the project will be made available in this website.
