VOUVRY Wastewater Treatment Plant, Vouvry, Valais, Switzerland

The VOUVRY wastewater treatment plant is located in Vouvry, a municipality in the Valais/Wallis canton of Switzerland. The plant serves a population of approximately 3,578 people and has a designed capacity of 1.00, indicating it is a small-scale facility typical of rural Alpine communities. As a Swiss wastewater treatment plant, VOUVRY operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment levels based on the sensitivity of receiving waters. For small agglomerations like Vouvry, secondary treatment is typically required, with possible tertiary treatment if the receiving water body is in a sensitive area. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River via the Rhône basin. The Rhône flows through the Valais region and into Lake Geneva (Lac Léman), a large alpine lake that supports diverse aquatic life and is an important ecological and recreational resource. The plant plays a key role in protecting downstream water quality in this sensitive alpine environment.

The VOUVRY plant discharges into the local water system that feeds the Rhône River, which flows through the Valais valley and into Lake Geneva (Lac Léman). Lake Geneva is a deep, oligotrophic lake that supports a variety of fish species and is a critical habitat for migratory birds. The plant's operations help maintain water quality in this ecologically sensitive alpine watershed, preventing nutrient enrichment and protecting downstream aquatic ecosystems.
