ST AUBIN Wastewater Treatment Plant, La Grande-Béroche, Neuchâtel

The ST AUBIN wastewater treatment plant is located in La Grande-Béroche, within the canton of Neuchâtel, Switzerland. It serves a population of approximately 4,654 residents, classifying it as a small agglomeration under Swiss water management standards. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. As a Swiss treatment facility, ST AUBIN operates under the Swiss Water Protection Act (Gewässerschutzgesetz), which mandates appropriate treatment levels based on the sensitivity of receiving waters. For small agglomerations like this, secondary treatment is typically required, with potential additional nutrient removal if the receiving water body is sensitive. The treated effluent from ST AUBIN likely discharges into a local watercourse that 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 lake supports diverse aquatic life and is an important ecological and recreational resource. The plant's operations contribute to protecting this sensitive freshwater ecosystem from nutrient pollution and other contaminants.

The ST AUBIN plant discharges into a local tributary that flows into Lake Neuchâtel, a large peri-alpine lake in western Switzerland. Lake Neuchâtel is part of the Rhine river basin, with its waters eventually reaching the North Sea. The lake supports diverse aquatic life, including fish species such as perch and whitefish, and is an important migratory stopover for waterbirds. Protecting water quality in this lake is critical for maintaining its ecological balance and recreational value.
