Foptaced with the challenge of installing conventional gravity pipes being impossible due to a "white tank" with a thickness of only 20 cm, Roediger® turned to vacuum technology for the extensive renovation work in the Forum Köpenick shopping paradise. To facilitate the installation of a new system for collecting and transporting wastewater, including condensate from freezers, the managers chose Roediger® vacuum technology. The system's shallow installation depth for pipes and its ability to transport wastewater upwards addressed structural challenges and met the highest hygiene requirements in the existing building complex.
