NEUF BERQUIN Wastewater Treatment Plant, Neuf-Berquin, Hauts-de-France

NEUF BERQUIN is a wastewater treatment plant located in Neuf-Berquin, a commune in the Nord department of Hauts-de-France, France. The plant serves a population of 2,768 and is part of the region's municipal wastewater infrastructure, operating under French regulations that transpose the EU Urban Waste Water Treatment Directive. The plant employs advanced treatment processes, which go beyond the secondary treatment required for agglomerations of this size under the EU directive. With a designed capacity of 2,667 m³/day and an average discharge volume of 493.81 m³/day, the facility is operating well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the North Sea via the Lys River and the Scheldt estuary. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the downstream rivers and contributing to the ecological health of the North Sea coastal zone.

The plant discharges into the local water system that flows into the Lys River, a tributary of the Scheldt, which empties into the North Sea near the Belgian coast. This watershed supports diverse aquatic ecosystems and is important for migratory fish species. The advanced treatment level helps reduce nutrient loads, mitigating eutrophication risks in the downstream marine environment.
