RUEDLINGEN Wastewater Treatment Plant, Rüdlingen, Schaffhausen, Switzerland

RUEDLINGEN is a municipal wastewater treatment plant located in Rüdlingen, a village in the canton of Schaffhausen, Switzerland. The plant serves a small population of 977 residents and is part of the local wastewater infrastructure managed by the canton. The plant provides secondary treatment, which is the standard biological treatment required under Swiss water protection regulations. With a designed capacity of 1,633 m³/day and a current discharge volume of 443.48 m³/day, the facility operates well within its capacity. Swiss regulations, aligned with the EU Urban Waste Water Treatment Directive, mandate secondary treatment for agglomerations of this size. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River. The Rhine is a major European waterway that flows through Switzerland, Germany, and the Netherlands before reaching the North Sea. The plant plays a key role in protecting the water quality of the Rhine basin by reducing organic pollutants and nutrients from domestic wastewater.

The plant discharges into the Rhine River basin, which flows through Switzerland and into the North Sea. The Rhine supports diverse aquatic life and is an important migratory corridor for fish. Downstream, the river passes through densely populated and industrial areas, making nutrient and pollutant removal critical for maintaining ecological balance.
