VILLERS OUTREAUX Wastewater Treatment Plant, Malincourt, Hauts-de-France

VILLERS OUTREAUX is a wastewater treatment plant located in Malincourt, a commune in the Nord department of Hauts-de-France, France. The plant serves a population of approximately 3,500, reflecting its role in managing domestic wastewater for a small agglomeration in the region. Its advanced treatment level indicates a high standard of pollutant removal, aligning with French and EU environmental regulations. As an advanced treatment facility, VILLERS OUTREAUX employs processes that go beyond secondary treatment, likely including nutrient removal to protect sensitive water bodies. The plant has a designed capacity of 3,150 cubic meters per day and a current discharge volume of about 618 cubic meters per day, indicating operational headroom. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment, but France often mandates tertiary or advanced treatment in sensitive areas to reduce eutrophication risks. The treated effluent from VILLERS OUTREAUX is discharged into local waterways that ultimately drain into the Scheldt basin, flowing through northern France and Belgium toward the North Sea. This region is characterized by intensive agriculture and urban development, making advanced treatment crucial for protecting downstream aquatic ecosystems and meeting water quality targets under the EU Water Framework Directive.

The plant discharges into the Scheldt river basin, which flows through Hauts-de-France and Belgium before reaching the North Sea. This watershed supports diverse aquatic life and is ecologically sensitive due to agricultural runoff and urban pressures. Advanced treatment at VILLERS OUTREAUX helps reduce nutrient loads, mitigating eutrophication risks in downstream rivers and coastal waters.
