This century is characterized by global environmental problems. Surface water and river water pollution is of special importance, as clean water forms the foundation of life. It therefore requires special attention in terms of quality. Regional authorities are requested to prepare measures for the improvement of water quality and to establish its provision. In order to secure sustainability in international projects, local authorities develop innovative solutions for the safety of water in cooperation with foreign companies and institutions. Lately, a variety of such joint projects are being realized around the world, with the German Federal Ministry of Education and Research especially sponsoring projects that are based on the cooperative partnership between industry and science.
