Groundwater Yields of Germany 1:1,000,000 (ERGW1000) (WMS)

The map shows in a generalized form the distribution of groundwater resources in Germany, based on the yields of existing waterworks or potential yields derived from this data. Five yield levels have been classified, indicating a ranking of the groundwater resources in their importance for the drinking water supply. In addition to areas with significant or less significant resources, areas in which no contiguous and regionally significant groundwater resources are available or expected are presented. The regionally significant groundwater resources are further subdivided into subclasses of roughly quantified yields. The map is based on a publication of the BGR (Vierhuff, H., Müller, W. & Aust, H. 1981), which was extended to the territory of the new federal states (Müller, A. 1993).
