LUTRY Wastewater Treatment Plant, Lutry, Vaud, Switzerland

The LUTRY wastewater treatment plant is located in Lutry, a municipality in the canton of Vaud, Switzerland, on the shores of Lake Geneva. The plant serves a population of approximately 8,036 residents and has a designed capacity of 1.00, reflecting its role in managing local domestic wastewater. Switzerland's wastewater treatment standards are governed by the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for discharges into sensitive water bodies like Lake Geneva. Plants serving agglomerations of this size are typically required to achieve secondary treatment with nutrient removal to protect the lake's water quality. The plant's treated effluent is discharged into Lake Geneva, which is part of the Rhône River basin. Lake Geneva is the largest freshwater lake in Western Europe and supports diverse aquatic life, including endemic fish species. The lake ultimately drains via the Rhône River into the Mediterranean Sea, making the plant's performance important for both local and downstream ecosystems.

The plant discharges into Lake Geneva, the largest alpine lake in Western Europe, which is part of the Rhône River basin. The lake supports a rich ecosystem, including fish species such as Arctic char and whitefish, and is a critical water resource for the region. Downstream, the Rhône River flows through France to the Mediterranean Sea, so effective treatment helps protect both lake and coastal waters.
