HOTTON Wastewater Treatment Plant, Hotton, Luxembourg, Belgium

The HOTTON wastewater treatment plant is located in the town of Hotton, within the province of Luxembourg in the Walloon region of Belgium. It serves a population of 1,167 people, classifying it as a small agglomeration under European Union regulations. The plant is situated inland, away from coastal areas, and its operations are part of Belgium's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. It has a designed capacity of 3,600 m³/day, with a reported discharge volume of 208.60 units. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Meuse River basin, which flows through Belgium and the Netherlands into the North Sea. The plant plays a key role in protecting the water quality of the region's rivers and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Meuse River basin, which flows northward through Belgium and the Netherlands before emptying into the North Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The secondary treatment helps reduce nutrient loads and organic pollution, contributing to the ecological health of the river system and the downstream marine environment.
