The water industry is undergoing major shifts. Climate change, demographic change and a discernible investment backlog in the water management infrastructure confront us with serious challenges. The sewage water management systems are intended not only to serve the environment and health, but also to conserve resources and save energy.

The expectation of sustainability and efficiency is growing steadily. Science and practice are required here to identify new possible solutions and to test them in practice. How efficient are stormwater tanks? How does climate change actually work - what does this mean for municipalities? How can organic pollutants be eliminated in sewage treatment plants? What contribution can urban water management make to renewable energies? How can energy from wastewater be generated?  Questions that we explore in cooperation with universities, various competence centers, expert committees and working groups. We are actively driving developments forward, and are continually integrating the results into our projects.
