REBECQ Wastewater Treatment Plant, Rebecq-Rognon, Belgium

The REBECQ wastewater treatment plant is located in Rebecq-Rognon, within the Brabant wallon province of Belgium. It serves a small population of 1,163 people, making it a small-scale municipal facility. The plant is situated in the Walloon region, which is part of the broader Meuse River basin. 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 of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The facility has a designed capacity of 5,400 m³/day, with an average discharge volume of 207.89 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into local surface waters, which eventually flow into the Senne River and then the Scheldt River, ultimately reaching the North Sea. The plant plays a key role in protecting the local aquatic environment by reducing pollutant loads before discharge. Its operation is regulated under Belgian and EU environmental standards, ensuring compliance with water quality objectives.

The plant discharges treated wastewater into local streams that are part of the Senne River sub-basin, which flows into the Scheldt River and eventually the North Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The Scheldt estuary is a critical habitat for migratory birds and fish species, making effective wastewater treatment essential for maintaining water quality and ecological health.
