CORCELLES PRES CONCISE Wastewater Treatment Plant, Corcelles-près-Concise, Vaud

CORCELLES PRES CONCISE is an advanced wastewater treatment plant located in Corcelles-près-Concise, in the canton of Vaud, Switzerland. The plant serves a population of approximately 1,500 residents and is part of the municipal infrastructure for the Jura-Nord vaudois district. Its designed capacity of 2,500 cubic meters per day indicates it is sized for a small agglomeration. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive water bodies. Under Swiss water protection law (Gewässerschutzgesetz), advanced treatment is required for plants serving more than 1,000 people in sensitive areas, aligning with this facility's configuration. The plant's treated effluent is discharged into the local watershed, which drains into Lake Neuchâtel, one of the largest lakes in Switzerland. Lake Neuchâtel is part of the Rhine basin, ultimately flowing into the North Sea. The advanced treatment helps protect the lake's water quality, which supports diverse aquatic life and recreational uses.

The plant discharges into the local watershed that feeds Lake Neuchâtel, a large freshwater lake in western Switzerland. Lake Neuchâtel is part of the Rhine basin, with outflow via the Zihl Canal into Lake Biel, then the Aare River, and finally the Rhine to the North Sea. The advanced treatment level ensures that nutrient loads are minimized, protecting the lake from eutrophication and supporting its ecological health, including fish populations and migratory birds.
