CHATEAU D OEX_BERCEAU Wastewater Treatment Plant, Les Moulins, Vaud

CHATEAU D OEX_BERCEAU is a wastewater treatment plant located in Les Moulins, within the municipality of Château-d'Oex in the Vaud canton of Switzerland. The plant serves a population of approximately 3,794 residents, making it a small-scale facility typical of alpine communities in the region. Switzerland's wastewater treatment standards are governed by the Federal Water Protection Act (Gewässerschutzgesetz), which mandates advanced treatment for plants discharging into sensitive water bodies. Plants of this scale in Switzerland commonly employ biological treatment with nutrient removal to meet stringent effluent quality requirements. The plant's treated effluent is discharged into the local watershed, which drains into the Sarine River (Saane), a tributary of the Aare River, ultimately flowing into the Rhine River and the North Sea. The alpine environment supports diverse aquatic life, and the plant plays a key role in protecting downstream water quality in this ecologically sensitive region.

The plant discharges into the local watershed that feeds the Sarine River (Saane), a tributary of the Aare River, which flows into the Rhine River and eventually the North Sea. The alpine streams in this region support sensitive aquatic ecosystems, including populations of brown trout and other cold-water species. Maintaining high treatment standards is critical to preserving water quality in this ecologically valuable area.
