VUARRENSBAS DE LA VAUX is an advanced wastewater treatment plant located in Vuarrens, within the District du Gros-de-Vaud in the canton of Vaud, Switzerland. The plant serves a small population of 385 residents and has a designed capacity of 900 m³/day, with a current discharge volume of 174.76 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. Under Swiss regulations, which align with the EU Urban Waste Water Treatment Directive, such treatment is typical for plants discharging into sensitive water bodies or upstream of protected areas. The plant discharges into local waterways that eventually drain into the Rhone River basin, which flows into Lake Geneva and then the Mediterranean Sea. Its advanced treatment helps protect the ecological health of these downstream waters, supporting aquatic life and water quality.
Environmental context
The plant's treated effluent enters local streams in the Gros-de-Vaud region, which are part of the Rhone River basin. The Rhone flows into Lake Geneva, a large alpine lake with significant ecological and recreational value, and continues to the Mediterranean Sea. Advanced treatment at this facility reduces nutrient loads, helping to prevent eutrophication in downstream waters and supporting diverse aquatic habitats.
