The project "MURIEL - Multifunctional Urban Retention Spaces: From Idea to Realization", funded by the German Federal Environmental Foundation, was successfully completed. The German Federal Environmental Foundation in Osnabrück commissioned DAHLEM as part of a joint venture with the research project, which aims to show ways in which existing inner-city open spaces can be used as emergency flooding areas during heavy rainfall events. The use of public open spaces as temporary retention areas is an important and necessary contribution to municipal flooding prevention - especially with regard to climate change. The three-part documentation summarizing how such retention rooms can be implemented and what needs to be considered in the concept and design is available for download here.
By means of holistic optimization, Waste Water Treatment Plant Aachen-Soers has succeeded in reducing the enormous energy demand of the recovery by around 55 per cent. Together with DAHLEM, the Wasserverband Eifel Rur planned the modernization of the oxygen supply of the aeration tanks. The design was implemented at the beginning of the year, followed by the commissioning of the blower station mid-year. The RWTH Aachen accompanies the project scientifically. DAHLEM supported the process design, which was modeled in a 3D-planning and accompanied the award procedure. The enclosed article about the project provides detailed information about the modernization of the plant. The waste water treatment plant is also referred to as a nationwide model Enterprise.
