VEVEY_AVIRON Wastewater Treatment Plant, Vevey, Vaud, Switzerland

VEVEY_AVIRON is a wastewater treatment plant located in Vevey, in the canton of Vaud, Switzerland. Situated on the shores of Lake Geneva (Lac Léman), the plant serves a population of around 52,702, placing it in the medium agglomeration category under Swiss and EU regulatory frameworks. As a Swiss plant, VEVEY_AVIRON operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for discharges into sensitive water bodies like Lake Geneva. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), and it is expected to provide at least secondary treatment with phosphorus removal to protect the lake from eutrophication. The treated effluent from VEVEY_AVIRON discharges into Lake Geneva, which flows into the Rhône River via the lake's outlet in Geneva. Lake Geneva is a large, deep alpine lake that supports diverse aquatic life and serves as a critical freshwater resource for the region. The plant plays a key role in maintaining the lake's water quality and ecological health.

VEVEY_AVIRON discharges into Lake Geneva, the largest alpine lake in Europe, which drains via the Rhône River into the Mediterranean Sea. The lake is ecologically sensitive, supporting a variety of fish species and providing habitat for migratory birds. Nutrient loading from wastewater can lead to algal blooms, so the plant's treatment must effectively remove phosphorus and nitrogen to protect the lake's oligotrophic status.
