Water quality and water protection
Under the heading “Water quality and water protection” information about the results of various monitoring programmes is provided. They indicate the quality of surface waters (rivers and lakes) and of the groundwater in Austria.
In the sub-category “Wastewater” you will find general information on wastewater disposal and wastewater treatment in Austria as well as technical instructions for the implementation of the different, sector-specific Wastewater Emission Ordinances.
Relevance of rock glaciers for water management
What does the water storage behaviour of Austrian rock glaciers, their runoff dynamics, hydrochemistry and heavy metal pollution have to do with the use of future water resources or climate change? A current research report provides information on this.
Drinkable deep groundwaters in Austria
In the basins of the eastern regions of our federal territory, drinkable deep groundwaters are in many cases the most important, often even the only, source of drinking water.
Protection and Monitoring of Water Bodies
Protection and monitoring of water bodies have a long tradition in Austria.
Chemical-physical terms around water
What is meant by water hardness, pH value or electrical conductivity?
STOBIMO Trace Substances - Modelling of point and diffuse emissions of trace substances
The STOBIMO Trace Substances Modelling project investigates the origin of selected inorganic and organic trace substances in Austrian water bodies at the level of catchment areas, identifies a potential risk of failing to meet the environmental objectives, and analyses possible action scenarios.
How is the quality of groundwater monitored and what are the costs of monitoring?
Sewage treatment plants in Austria
Wastewater treatment has reached a very high quality standard in Austria, also compared to international standards.
Wastewater in Austria
Apart from the wastewater from municipal and industrial wastewater treatment facilities, also polluted precipitation water is considered wastewater.
How does a sewage treatment plant work?
Wastewater is usually purified in three stages and includes the mechanical, biological and chemical sewage treatment steps.
