The plant's operations contribute to maintaining water quality in this transboundary river system.

The plant is situated in the Murg River watershed, which flows into the Rhine River near Koblenz, Switzerland. The Rhine is a major European river that drains into the North Sea, supporting diverse ecosystems including fish spawning grounds and migratory corridors. The region's water quality is regulated under the Rhine Protection Convention, requiring advanced treatment to minimize nutrient and pollutant loads.
