Villers-la-Ville Wastewater Treatment Plant, Brabant wallon, Belgium

The Villers-la-Ville wastewater treatment plant is located in the municipality of Villers-la-Ville, within the Brabant wallon province of Wallonia, Belgium. It serves a population of approximately 2,076 people, classifying it as a small agglomeration under EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 8,000 m³/day, with an actual discharge volume of 371.08 m³/day, indicating significant reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin, flowing toward the North Sea. This contributes to the protection of downstream aquatic ecosystems and supports water quality objectives under the EU Water Framework Directive.

The plant discharges into the local river network within the Scheldt basin, which flows through Belgium and the Netherlands before reaching the North Sea. The downstream environment supports diverse freshwater and estuarine habitats, including important migratory fish species. Effective treatment helps reduce nutrient loads and organic pollution, safeguarding water quality in this densely populated and agriculturally active region.
