Water – dirty, clean, purest

The visitor tour through the sewage treatment plant in Werdhölzli begins at the entrance canal that transports the entire wastewater of the city of Zurich into the sewage treatment plant. It is impressive to see these huge amounts flowing towards the cleansing process. The tour follows the flow and shows the different cleansing stages. Not all the processes can be shown, and not all are understandable. This is why we support the professional guides with didactic shows.

In order to liven up the long walks between areas, we have enriched them with small, goal-oriented surprises such as a slide from the «upper canal».
