6 Fig. 2: Water withdrawals in the German Danube River Basin (Source: LMU)
2.1 Public water supply The public water supply comprises domestic use and small trade in addition to public institutions. In the Bavarian Danube Basin exists three major water supply groups: • “Wasserversorgung Bayrische Riesgruppe”, • “Wasserversorgung Bayrischer Wald“ (groundwater of Isar mouth) and • “Wasserversorgung Fränkischer Wirtschaftsraum“ (mouth of Lech). The largest groundwater resources can be found in the Danube valley (BAYERISCHES STAATSMINISTERIUM FÜR UMWELT, GESUNDHEIT UND VERBRAUCHERSCHUTZ 2005). In the year 2001 about 3.77 billion m³ out of 51 billion m³ of water were extracted, 74.3 percent out of surface waters. The table below gives a more detailed overview about the water needs in the German UDRB. In Baden-Württemberg on average about 5% of available fresh water resources were extracted. In 2002 that means an extraction of 20 mm from runoff of 350mm. The percentage varies in the area between 5 and 10 %. Perceptions are the water resources in the Ostalb, which suffer from intensive water use (25 %, 85 mm). In respect to the ratio of groundwater recharge and groundwater extraction it is also in general below 10%, except the Ostalb with extraction rates till 15% or 25%. The can be explained by the use of a spring by the Landeswasserversorgung (UMWELTMINISTERIUM BADEN-WÜRTTEMBERG 2008). Tab. 2: Water extraction in the German DRB (BAYERISCHES STAATSMINISTERIUM FÜR UMWELT, GESUNDHEIT UND VERBRAUCHERSCHUTZ 2005).

The manufacturing industry extracted 750 Mio. m³ predominantly from surface water, whereas 85 percent of the water for agriculture was taken from groundwater sources, mostly used for irrigation. This is equivalent to a volume of 390m³ irrigation water per ha. The public water extraction was about 790 Mio. m³, 94 percent of it from ground or spring water (BAYERISCHES LANDESAMT FÜR WASSERWIRTSCHAFT 2005). 7
