Hoeselt Wastewater Treatment Plant: Serving Hoeselt, Limburg, Belgium

The Hoeselt wastewater treatment plant is located in the town of Hoeselt, within the province of Limburg, Flanders, Belgium. It serves a population of around 7,100 residents, placing it in the small-to-medium agglomeration category under European Union classification. As a Belgian plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into freshwater. The regulatory framework ensures compliance with national and EU standards for effluent quality. The treated effluent is discharged into local watercourses that ultimately drain into the Demer River basin, part of the Scheldt River system flowing to the North Sea. The plant plays a key role in protecting the region's surface water quality and supporting the ecological health of downstream aquatic habitats.

The Hoeselt plant discharges into the Demer River basin, which flows into the Dijle and then the Rupel, eventually reaching the Scheldt estuary and the North Sea. This watershed supports diverse aquatic life and is important for migratory fish species. The plant's treatment helps maintain water quality in this sensitive river system.
