Source of Water in Düsseldorf, Germany

Düsseldorf’s tap water comes from groundwater and naturally filtered Rhine water, known as bank filtrate. Water is extracted from wells near the Rhine and treated at Düsseldorf’s waterworks.

The main waterworks are in Flehe, Holthausen, and Am Staad. Treatment removes impurities and adjusts the water quality before it enters the municipal distribution network.
