Overview
Salzweg wastewater treatment plant serves the Bavarian town of Salzweg, Germany, with a population equivalent of 3,626. The facility discharges treated effluent into the local watershed, contributing to the Danube River basin.
The Salzweg wastewater treatment plant is a municipal facility located in the town of Salzweg, in the Landkreis Passau district of Bavaria, Germany. It serves a population equivalent of 3,626, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in a rural-urban setting near the Ilz River, a tributary of the Danube. As a German plant serving fewer than 10,000 people, it is subject to the EU UWWTD requirements, which mandate secondary treatment for discharges into freshwater. The plant's treatment process is designed to meet national standards under the German Water Resources Act (Wasserhaushaltsgesetz), ensuring compliance with effluent quality parameters for biological oxygen demand and suspended solids. The treated wastewater is discharged into the Ilz River, which flows into the Danube near Passau. The Danube then continues through several Central and Eastern European countries before reaching the Black Sea. The plant plays a role in protecting the Ilz's water quality, which supports diverse aquatic life and is part of a region known for its natural landscapes.
Environmental context
The plant discharges into the Ilz River, a tributary of the Danube River. The Danube is Europe's second-longest river, flowing through ten countries and draining into the Black Sea. The Ilz is a relatively small river that supports a variety of fish species and riparian habitats. The region is ecologically sensitive due to its proximity to the Bavarian Forest, and the plant's operations help maintain water quality in this important watershed.
