Water

Located on the banks of a mighty river, Vienna has taken precautions and built a flood protection system designed to cope with disasters that occur only once every 10,000 years. Vienna also cares for its water: the city's sewer system, controlled by the latest technologies, collects wastewater and carries it to one of Europe's most modern treatment plants where it is treated with an efficiency of over 95 percent. Vienna's drinking water comes from high in the Alps and is renowned for its quality and purity. Finally, Vienna protects its lakes, streams and rivers because surface water is a critical element in high-quality natural and recreational areas.
