The Institute for Urban Water Management is part of the Faculty of Hydrosciences of the Dresden University of Technology. The faculty includes both natural sciences and engineering sciences dealing with research and education on water topics, and is thus experienced in carrying out interdisciplinary projects.

The institute has experience in both praxis-oriented and basic-research projects. The extension of the wastewater treatment plant (WWTP) and the rehabilitation and operation of the sewer system of Dresden
were largely influenced by various investigations of the institute. A main emphasis was on balancing sewer sediments and its influence on the characteristics of compounds flushes to the WWTP. Also, the effect of infiltrating groundwater to the sewer system was referred to as a source of nitrate, which is a topic that is of direct interest to the present project. Contract work in collaboration with private companies is an important contribution to the interface between research and its practical application. Model development, modelling
and integration of the wastewater system including the sewer system, the WWTP and the receiving water
are the main research topics of the participating group.
