Feuchy Wastewater Treatment Plant | Hauts-de-France, France

The Feuchy wastewater treatment plant is located in the commune of Feuchy, within the Pas-de-Calais department of the Hauts-de-France region in northern France. The facility serves a population of approximately 3,400 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, exceeding the EU Urban Waste Water Treatment Directive's minimum requirement of secondary treatment for agglomerations of this size. Its designed capacity is 3,000 cubic meters per day, with an actual discharge volume of 606.55 cubic meters per day, indicating operational headroom. Treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin and the North Sea. The plant plays a key role in protecting the region's aquatic ecosystems and groundwater resources, supporting both agricultural and urban water quality in the Arras area.

The plant discharges into the Scarpe River system, a tributary of the Scheldt, which flows through the Hauts-de-France region before reaching the North Sea near Antwerp. The downstream environment includes agricultural plains and urban areas, where maintaining water quality is critical for biodiversity and drinking water sources. The advanced treatment helps reduce nutrient loading and protects sensitive aquatic habitats in the Scheldt estuary.
