Exact knowledge of the current groundwater levels, and hence also of groundwater stocks, is imperative for the State of Berlin, since the water for the public water supply of Berlin (221 million cu.m. in 2016) is obtained from groundwater. This groundwater is pumped at nine waterworks, almost entirely within the territory of the city. Only the Stolpe Waterworks on the northern outskirts obtains water from Brandenburg, but also supplies Berlin with approx. 9 % of the city’s total intake (Fig. 1).
