Environmental context
Rohrnbach's treated wastewater enters small streams in the Bavarian Forest region, which feed into the Ilz River, a tributary of the Danube. The Danube then flows through several countries before reaching the Black Sea. The local watershed supports diverse aquatic life, including fish species such as brown trout and grayling, and the forested catchment provides important habitat for wildlife. The plant's operations help preserve the ecological integrity of these downstream environments.
