Overview
TRIENT wastewater treatment plant in Trient, Valais, Switzerland serves 160 people with secondary treatment. It discharges 72.63 m³/day and has a design capacity of 375.00 m³/day.
TRIENT is a municipal wastewater treatment plant located in the village of Trient, within the Valais/Wallis canton of Switzerland. It serves a small population of 160 residents, reflecting the rural and alpine character of the area. The plant is situated near the Col de la Forclaz in the Martigny district. The facility provides secondary treatment, which is appropriate for small agglomerations in Switzerland. Under Swiss water protection law (Gewässerschutzgesetz), secondary treatment is the minimum standard for discharges into sensitive alpine water bodies. The plant has a design capacity of 375.00 m³/day and currently treats an average daily flow of 72.63 m³/day, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that drain into the Rhône River basin. The Rhône flows through the Valais valley and eventually into Lake Geneva (Lac Léman), a large alpine lake with significant ecological and recreational value. The plant's operation helps protect downstream aquatic habitats and water quality in the Rhône watershed.
Environmental context
The plant discharges into small streams that feed the Trient River, a tributary of the Rhône. The Rhône flows through the Valais Alps and into Lake Geneva, one of Europe's largest freshwater lakes. The watershed supports diverse aquatic life, including fish species such as brown trout and Arctic char, and is an important corridor for migratory birds. Protecting water quality in this alpine region is critical for maintaining the ecological integrity of the Rhône basin and Lake Geneva.
