The Rheinfelden wastewater treatment plant is located in the town of Rheinfelden in the canton of Aargau, Switzerland. It serves a population of about 31,125, making it a medium-sized municipal facility in the Upper Rhine region. The plant is situated near the border with Germany, on the southern bank of the Rhine River. As a Swiss wastewater treatment facility, Rheinfelden operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment standards to protect water quality. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially given the sensitivity of the Rhine as a transboundary waterway. The plant's treatment processes are designed to meet stringent effluent limits set by federal and cantonal authorities. The treated wastewater is discharged into the Rhine River, which flows northward through Germany and the Netherlands before reaching the North Sea. The Rhine is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant's operations contribute to maintaining the ecological health of the river and its downstream environments.
