Ghent Nieuwe Dokken, Belgium

Vacuum Sewer and Sanitary System

Similar to many other cities, the transformation in the shipping industry posed significant challenges for the municipality of Ghent. The former dock and harbor area in the heart of the city had become an extensive industrial wasteland. Collaborating with local companies, Roediger® developed a complete infrastructure project for the area, transforming it into an attractive residential space along the waterfront. The extensive use of vacuum technology in 400 residential units provided impressive efficiency, offering substantial opportunities for water conservation and energy recovery. Since 2019, Ghent Nieuwe Dokken has showcased the possibilities that vacuum solutions bring to modern, forward-thinking urban planning.
