ARA GAV Unteres Schmidatal 1399 KO - Advanced Wastewater Treatment in Schmida, Niederösterreich

ARA GAV Unteres Schmidatal 1399 KO is a wastewater treatment plant located in Schmida, a village in the district of Korneuburg, Niederösterreich, Austria. The plant serves a population of approximately 5,137 and has a design capacity of 6,000 cubic meters per day, with an average discharge volume of 747.53 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Austrian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The plant's advanced treatment level suggests it serves a sensitive area or meets stringent national standards. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream uses. Its location in a rural area of Niederösterreich highlights the importance of decentralized wastewater management in maintaining environmental health.

The plant discharges into small streams that feed into the Danube River basin, ultimately reaching the Black Sea. The local watershed supports agricultural land and diverse aquatic life. Advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream water bodies and maintaining ecological balance in the Danube ecosystem.
