Extraction of Water for Public Drinking Water Supply

• The supply of drinking water in the Upper Danube drainage basin is generally a municipal responsibility and based almost exclusively on extraction from ground- and spring water sources. This section presents maps showing an overview of the quantities extracted and regional variations. Extraction depends both on the water yield, which may be constrained by local hydrogeological conditions, and on consumption, which is mainly a result of population density. The map shows the aggregated quantities of water extracted from ground-, spring and surface water sources in the communities and the points of drinking water withdrawal within the drainage basin for the year 1998. This information is used by the WaterSupply model, which provides the connection between water availability (Groundwater and Rivernetwork models) and water demand (actor models) within DANUBIA. This chapter describes the data sources and the processing steps taken in preparation of the presented map. Limitations and sources of uncertainty are discussed.
