Breathing new life into a former German army base, Hamburg-Jenfeld has become home to nearly 3,000 residents. Roediger® implemented the combination of vacuum toilets and a vacu-um sewer system for the entire residential area, setting a high standard in both operating effi-ciency and sustainability. The drinking water consumption of the vacuum toilets is only 10% of that used by conventional technology. Thanks to the consistent separation of material flows, wastewater can be utilized for generating heat and reused in the settlement's own lake.
