The university‘s goal is to tackle complex problems and global challenges and work to ensure that knowledge and innovations benefit society. In its nine departments, education and research in civil, mechanical, electrical and environmental engineering, economics and management, life science technologies, architecture and design is provided.

Education is offered at the BSc and MSc level in all departments. In addition, more than 50 PhD students are enrolled who are working on numerous research topics.

The university’s key research area “Sustainable water management and water pollution control” is directed by the department. In recent years, several national and international water related research projects have been conducted for federal ministries, state authorities and the German Federal Environmental Foundation (DBU). The academic staff is active in national and international professional groups of several water associations, and in standards committees.
