BOUILLON Wastewater Treatment Plant, Bouillon, Luxembourg Province, Belgium

The BOUILLON wastewater treatment plant is located in Cordemois, Bouillon, within the Luxembourg province of Wallonia, Belgium. It serves a population of 1,645 and operates under Belgium's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant has a designed capacity of 6,750 cubic meters per day and currently treats a discharge volume of 294.04 cubic meters per day. As a secondary treatment facility, it meets the EU directive's minimum standards for organic matter and suspended solids removal before discharge. The treated effluent is released into the local watercourse, which flows into the Semois River and eventually reaches the Meuse River basin. The Semois Valley is an ecologically sensitive area known for its diverse aquatic life and forested landscapes, making proper wastewater treatment essential for preserving water quality and biodiversity.

The plant discharges into a tributary of the Semois River, which flows through the Ardennes region into the Meuse River and ultimately drains into the North Sea. The Semois Valley supports diverse aquatic ecosystems and is an important corridor for migratory fish species. The surrounding forested watershed is sensitive to nutrient pollution, making secondary treatment crucial for maintaining ecological balance.
