Morbecque Wastewater Treatment Plant, Steenbecque, Hauts-de-France

The Morbecque wastewater treatment plant is located in Steenbecque, a commune in the Nord department of the Hauts-de-France region, France. It serves a small population of 497 people, reflecting its role in a rural community. The plant is situated near the Route Nationale and operates within the municipal infrastructure of the Dunkerque area. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 10,000. Its designed capacity of 4,000 m³/day indicates it can handle peak flows, while the actual discharge volume of 88.66 m³/day suggests low utilization, typical for a small community. The treated effluent is discharged into local waterways that drain into the North Sea via the Lys and Scheldt river basins. This region is part of the Flanders coastal plain, where water quality management is important for both ecological health and agricultural use. The plant's secondary treatment helps reduce organic pollutants and protect downstream aquatic life.

The plant discharges into the local river network that flows toward the North Sea, likely via the Lys or Scheldt basins. This area supports diverse freshwater habitats and is part of the Flanders coastal plain, which is ecologically sensitive due to its low-lying terrain and intensive agriculture. Effective wastewater treatment is crucial to prevent nutrient enrichment and maintain water quality in downstream rivers and coastal zones.
