Burgkirchen_Alz Wastewater Treatment Plant, Burgkirchen an der Alz, Bavaria

Burgkirchen_Alz is a wastewater treatment plant located in Burgkirchen an der Alz, in the Bavarian district of Altötting, Germany. The facility serves a population of around 10,944, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a German plant, it operates within the framework of the EU UWWTD and national water management laws. For agglomerations of this size, the directive requires at least secondary treatment, and if the receiving waters are sensitive, tertiary treatment may be mandated. The plant's treated effluent is discharged into the Alz River, a tributary of the Inn River, which flows into the Danube and ultimately the Black Sea. This river system supports diverse aquatic life and is an important ecological corridor in the region. The plant's location inland, away from coastal areas, reduces direct marine impact, but its discharge contributes to the overall water quality of the Danube basin.

The plant discharges into the Alz River, which flows into the Inn River, a major tributary of the Danube. The Danube River basin is one of Europe's most significant water systems, supporting diverse ecosystems and providing water for millions of people. The Alz River itself is a small river in Bavaria, and its water quality is important for local aquatic life and downstream habitats. The region is characterized by agricultural and industrial activities, making effective wastewater treatment crucial for maintaining ecological balance.
