Source of Water in Oldenburg, Germany

Tap water in Oldenburg, Lower Saxony, comes mainly from groundwater extracted by the Oldenburgisch-Ostfriesische Wasserverband (OOWV). A key source is the Sandkrug waterworks south of Oldenburg, which supplies the city and surrounding areas.

The groundwater is naturally filtered through layers of sand and soil before being pumped from protected wells. At the waterworks, it is aerated and filtered to remove iron and manganese, then tested and distributed through the public supply network.
