It serves a population of approximately 5,711 people, classifying it as a small to medium agglomeration under European Union regulations. The plant is situated in the Walloon region, near the town of Mariembourg, and plays a key role in managing local wastewater. As a facility in Belgium, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The directive ensures that plants of this scale meet minimum treatment standards to protect water quality. Its design aligns with regulatory expectations for its population tier. The treated effluent from Mariembourg Nismes is discharged into the local watershed, which ultimately drains into the Meuse River basin. The Meuse flows through Belgium and the Netherlands before reaching the North Sea. The plant's operation helps safeguard the ecological health of the Meuse River and its tributaries, supporting aquatic life and downstream water quality in the region.
