Impact of decreasing water demand on bank filtration in Saxony, Germany
University of Applied Sciences, Faculty of Civil Engineering/Architecture, Division of Water Sciences, Friedrich-List-Platz 1, 01069 Dresden, Germany
Abstract. Bank filtration has been of main importance for the drinking water supply in Germany for many decades. The water quality of pumped raw water from bank filtration sites depends to a high degree on the water quality of the infiltrating surface water and the landside groundwater, the mixing portion of both as well as the flow and transport conditions in the aquifer. Since the improvement of river water quality and a drastic decrease in water demand during the last 15 years in Germany, the influence of landside groundwater quality has become more important for the raw water quality of waterworks relying on bank filtration. The hydrogeologic analysis of three bank filtration sites in Saxony and the management of abstraction rates and well operation in response to fluctuating water demand are discussed. In conclusion, a general overview on management options for bank filtration sites is provided.
