The city of Vienna is world famous for its position on the River Danube. Every day Vienna's residents consume around 370,000 cubic metres of water, which is not uncommon for a city of over a million people. However the fact that not a single drop comes from the great river is amazing. All of the water that is drunk or cooked with, that flows through showers, sinks and fountains into the city's drains and wastewater treatment plants comes from the alps. Vienna's exclusive water factory lies in the eastern limestone alps. The Rax-Schneeberg region in Lower Austria and the Styrian Hoschschwab are the natural reservoirs from which water has flowed to Vienna for almost 150 years. It follows the natural inclines from the mountains along two pipelines into the federal capital, where it collects in large reservoirs and is distributed via a network that is approximately 3000 km long.
