The Drainage + Recycling Zurich (ERZ) division is replacing 2 high-pressure flushing vehicles that have been in use for 12 years with 2 5-axle water recycling vehicles (WFZ). The new WFZ must be able to vacuum and flush at the same time. A steered trailing axle ensures high maneuverability. The waste water chambers are to be constructed as large as possible. The latest emission standards must be observed and the latest drive technology (hybrid / electric) must be taken into account. Further details can be found in the service description (PART D, Form D2).
