LUSSERY VILLARS Wastewater Treatment Plant, Daillens, Vaud, Switzerland

LUSSERY VILLARS is a wastewater treatment plant located in Daillens, within the district of Gros-de-Vaud in the canton of Vaud, Switzerland. It serves a small population of 267 people, reflecting its role in a rural or peri-urban community. The plant is situated near the coast, within 10 km of Lake Geneva, which influences its environmental context. The plant employs advanced treatment processes, ensuring a high level of pollutant removal. Its designed capacity is 625 m³/day, while current discharge volume is 121.20 m³/day, indicating operational headroom. As a Swiss facility, it operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates stringent standards for wastewater treatment, particularly for plants discharging into sensitive water bodies like Lake Geneva. The treated effluent likely discharges into local streams that flow into Lake Geneva, a major European lake and part of the Rhône basin. Lake Geneva supports diverse aquatic life and is a critical drinking water source for the region. The plant's advanced treatment helps protect this ecosystem from nutrient pollution and other contaminants.

The plant discharges into the Lake Geneva watershed, which drains via the Rhône River into the Mediterranean Sea. Lake Geneva is a large, deep lake with significant ecological value, supporting fish species such as Arctic char and whitefish. The advanced treatment at LUSSERY VILLARS helps minimize nutrient loading, protecting the lake from eutrophication and maintaining water quality for downstream ecosystems.
