Beaurainville Wastewater Treatment Plant, Hauts-de-France, France

The Beaurainville wastewater treatment plant is located in the commune of Beaurainville, within the Pas-de-Calais department of the Hauts-de-France region in northern France. The facility serves a population of approximately 6,283 people, classifying it as a small to medium agglomeration under EU classification. The plant is situated near the Canche river basin, which flows into the English Channel. As a French wastewater facility serving fewer than 10,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into fresh water and estuaries. The directive also mandates appropriate treatment for sensitive areas, which may include nutrient removal. This likely refers to a capacity in thousands of cubic meters per day or population equivalent. The treated effluent from Beaurainville is discharged into the local watershed, which ultimately drains into the Canche River and then into the English Channel. The Canche estuary is an ecologically important area, supporting diverse birdlife and aquatic habitats. The plant's operation helps protect the water quality of this coastal environment, which is vital for local biodiversity and tourism.
