Overview
Cysoing wastewater treatment plant in Hauts-de-France, France, serves about 2,871 people with advanced treatment. It discharges 512.18 m³/day and has a designed capacity of 10,500 m³/day.
The Cysoing wastewater treatment plant is located in the commune of Cysoing, within the Hauts-de-France region of northern France. It serves a population of approximately 2,871, 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 region's municipal wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 10,500 m³/day and a current discharge volume of 512.18 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The advanced treatment level suggests that the plant likely includes nutrient removal or other tertiary steps to protect sensitive receiving waters. The treated effluent is discharged into a local watercourse that ultimately drains into the Scheldt River basin, which flows through Belgium and the Netherlands before reaching the North Sea. This downstream pathway highlights the plant's role in maintaining water quality in a transboundary river system. The advanced treatment helps reduce nutrient loads and pollutants, supporting aquatic life and downstream ecosystems.
Environmental context
The plant discharges into a local watercourse that is part of the Scheldt River basin. The Scheldt flows through France, Belgium, and the Netherlands, eventually reaching the North Sea via the Western Scheldt estuary. This basin supports diverse aquatic habitats and is an important migratory corridor for fish. The advanced treatment at Cysoing helps minimize nutrient and pollutant inputs, protecting downstream water quality in this ecologically sensitive river system.
Frequently asked questions
The Cysoing wastewater treatment plant is located in Cysoing, a commune in the Nord department of Hauts-de-France, France. The address is M 94, Le Peuville, Cysoing, Lille, Nord, Hauts-de-France, 59830.
The Cysoing plant serves a population of approximately 2,871 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive.
The plant discharges treated effluent into a local watercourse that is part of the Scheldt River basin. The Scheldt flows through France, Belgium, and the Netherlands, eventually reaching the North Sea.
The Cysoing plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive for small agglomerations. This typically includes nutrient removal to protect sensitive water bodies.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment based on agglomeration size. For small agglomerations like Cysoing (under 10,000 population equivalent), the directive requires appropriate treatment, and France implements this through national regulations. The advanced treatment at Cysoing exceeds the minimum requirements.
