FLIXECOURT SE Wastewater Treatment Plant, Flixecourt, Hauts-de-France

FLIXECOURT SE is an advanced wastewater treatment plant located in Flixecourt, a commune in the Somme department of Hauts-de-France, northern France. The facility serves a population of 3,770 and is part of the region's municipal wastewater infrastructure, operating under French regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients such as nitrogen and phosphorus. With a designed capacity of 5,400 m³/day and an actual discharge volume of 672.56 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The facility is classified as a small agglomeration under the EU directive, which requires appropriate treatment to protect the receiving environment. The treated effluent is discharged into local watercourses that eventually drain into the Somme River basin. The Somme River flows westward into the English Channel, supporting diverse aquatic habitats and wetlands. The advanced treatment level helps minimize nutrient loading and protects the ecological health of the downstream river and coastal zone.

The plant discharges into the Somme River basin, which flows into the English Channel. The Somme River and its estuary support important bird populations and aquatic life, including migratory fish species. Advanced treatment reduces nutrient pollution, safeguarding water quality in this ecologically sensitive region.
