Source of Water in Karlsruhe, Germany
Karlsruhe’s tap water comes entirely from groundwater in the Upper Rhine Valley aquifer. The water is collected through wells in and around the city’s forested areas, including the Hardtwald and Durlacher Wald.
Karlsruhe’s municipal waterworks treat and distribute this groundwater to homes and businesses. The water is naturally filtered through layers of sand and gravel before treatment and is regularly monitored under German drinking-water standards.
