CORCELLES PRES PAYERNE Wastewater Treatment Plant, Corcelles-près-Payerne, Vaud

CORCELLES PRES PAYERNE is an advanced wastewater treatment plant located in Corcelles-près-Payerne, in the Vaud canton of Switzerland. The facility serves a population of 1,627 and has a designed capacity of 2,719 cubic meters per day, with a current discharge volume of 738.53 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under Swiss regulations, which align with the EU Urban Waste Water Treatment Directive, advanced treatment is often required for sensitive areas or larger agglomerations. For a plant of this scale, the advanced treatment level indicates a high standard of environmental protection. The treated effluent is discharged into local water bodies that eventually drain into the Broye River and then into Lake Neuchâtel, part of the Rhine basin. This watershed supports diverse aquatic life and is important for regional water quality. The plant's advanced treatment helps protect downstream ecosystems and recreational uses.

The plant discharges into the Broye River, which flows into Lake Neuchâtel, one of the largest lakes in Switzerland. Lake Neuchâtel is part of the Rhine basin and supports diverse aquatic life, including fish species such as perch and pike. The advanced treatment at this plant helps maintain water quality in the lake, which is used for recreation and as a drinking water source.
