Gouzeaucourt Wastewater Treatment Plant, Hauts-de-France | Advanced Treatment for 2,650 Residents

The Gouzeaucourt wastewater treatment plant is located in the commune of Gouzeaucourt, in the Nord department of Hauts-de-France, France. It serves a population of approximately 2,650 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,500 m³/day and an actual discharge volume of 472.76 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The plant's advanced treatment likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin, which flows through Belgium and the Netherlands to the North Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic ecosystems and downstream water uses. Its advanced treatment helps reduce nutrient loads and other pollutants, contributing to the ecological health of the Scheldt estuary and coastal waters.

The plant discharges into local streams that are part of the Scheldt River basin. The Scheldt flows through France, Belgium, and the Netherlands before reaching the North Sea. This basin supports diverse aquatic life and is an important migratory corridor for fish. The advanced treatment at Gouzeaucourt helps minimize nutrient enrichment and pollution, protecting the ecological integrity of the downstream river system and the sensitive coastal environment of the North Sea.
