FEY Wastewater Treatment Plant, Fey, Vaud, Switzerland

FEY is a municipal wastewater treatment plant located in the village of Fey, within the District du Gros-de-Vaud in the canton of Vaud, Switzerland. It serves a small population of 178 residents, reflecting the rural character of the area. The plant is situated at Place de l'Eglise, Fey, and operates under Swiss water protection regulations. The plant provides secondary treatment, which is appropriate for its small scale. With a designed capacity of 417 cubic meters per day and an actual discharge volume of 80.80 cubic meters per day, it operates well below its capacity. Swiss regulations require adequate treatment for all agglomerations, and secondary treatment meets the standard for protecting receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Rhone River basin. The region's aquatic ecosystems benefit from the plant's treatment, which reduces organic load and nutrients. The plant contributes to maintaining water quality in the Vaud countryside, supporting local biodiversity and downstream uses.

The plant discharges into small streams that flow into the Broye River, a tributary of the Rhone. The Rhone ultimately reaches the Mediterranean Sea. The local watershed supports diverse aquatic life, including fish species such as brown trout. The plant's secondary treatment helps protect these ecosystems from nutrient enrichment and organic pollution.
