Water management in Berlin

Berlin's complex and technically demanding water management ensures excellent drinking water quality and very clean waters.

Several best practice examples are already in use in the city, such as the "offshore" mixed water storage unit in the Spree River, the retention ground filter for rainwater treatment or the many gray water recycling and rainwater harvesting systems in homes and offices.

Why Berlin?

„Berlin’s connection with water is unique: A water cycle that is unparalleled in Germany makes it possible to supply more than 90% of the city’s drinking water needs from sources within the metropolitan area. Berliner Wasserbetriebe supplies the city with water and disposes of wastewater. Work with other stakeholders has led to a variety of innovations to the water system in Berlin.“
