Beauvois-en-Cambrésis Wastewater Treatment Plant - Advanced Treatment in Hauts-de-France

The Beauvois-en-Cambrésis wastewater treatment plant is located in the Hauts-de-France region of northern France, serving the commune of Beauvois-en-Cambrésis. This facility is part of the municipal infrastructure that manages wastewater for a population of 4,125 residents, reflecting a small to medium agglomeration under French and EU classification. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 8,750 m³/day and an actual discharge volume of 735.89 m³/day, the facility operates well within its capacity, indicating potential for future growth or seasonal variations. Treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin, flowing through the Nord department towards the North Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the region, including the Scarpe-Escaut Regional Nature Park, by reducing nutrient loads and pollutants before discharge.

The plant discharges into local streams that are part of the Scheldt River basin, which flows through northern France and Belgium before reaching the North Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The advanced treatment level helps minimize eutrophication risks in downstream water bodies, particularly in the sensitive coastal zones of the North Sea.
