SART DAMES AVELINES Wastewater Treatment Plant, Villers-la-Ville, Belgium

SART DAMES AVELINES is a municipal wastewater treatment plant located in Villers-la-Ville, within the Brabant wallon province of Belgium. The plant serves a population of approximately 1,801 people and is part of the region's wastewater infrastructure managed under Belgian and European regulations. 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. With a designed capacity of 2,900 m³/day and a current discharge volume of 321.93 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin, which flows through Belgium and the Netherlands into the North Sea. The plant plays a key role in protecting the region's surface water quality and supporting downstream aquatic ecosystems.

The plant discharges into the local river system, part of the Scheldt basin, which flows through Wallonia and Flanders before reaching the North Sea. This watershed supports diverse aquatic life and is important for regional water quality. The secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream waters.
