This Research Group addresses questions on sewer systems and rainwater management. One focus of the group is the monitoring of contaminants in runoff from impervious surfaces. Another focus is the development and evaluation of decentralized treatment facilities for polluted runoff, often in close collaboration with companies.

The Research Group has a well-established track record in monitoring of heavy metals like copper and zinc from heavy metal roofs and road runoff. Beside legacy contaminants like heavy metals, organic pollutants like Methyl-tert-butylether or Ethyl-tert-butylether, which are widely used as anti-knocking agent, and biocides from building facades are of great research interest.In the field of managing sewer systems, one project worked on the estimation of costs for the construction of new and maintenance of existing sewer infrastructure which is of great interest.
