BOUSSENS Wastewater Treatment Plant, Boussens, Vaud, Switzerland

BOUSSENS is a wastewater treatment plant located in Boussens, a municipality in the District du Gros-de-Vaud, Vaud, Switzerland. The plant serves a small population of 320 people, reflecting its role in a rural or peri-urban setting. It operates under Swiss water protection regulations, which require advanced treatment for sensitive water bodies. The plant employs advanced treatment processes, ensuring high-quality effluent. With a designed capacity of 750 m³/day and a current discharge volume of 145.26 m³/day, the plant has significant spare capacity. This suggests it is designed to accommodate future growth or seasonal variations. The plant's location within 10 km of the coast indicates its discharge may influence coastal water quality. The treated effluent is discharged into the local watershed, which ultimately drains into Lake Geneva (Lac Léman) via the Venoge River. Lake Geneva is a major freshwater resource and ecologically sensitive area, supporting diverse aquatic life and serving as a drinking water source. The plant's advanced treatment helps protect this downstream environment from nutrient pollution and other contaminants.

The plant discharges into the Venoge River basin, which flows into Lake Geneva, one of Europe's largest lakes. Lake Geneva supports a rich ecosystem, including fish species like Arctic char and whitefish, and is a critical drinking water reservoir. The plant's advanced treatment reduces nutrient loads, helping to prevent eutrophication and maintain water quality in the lake.
