Chawresse is a wastewater treatment plant located in Esneux, within the Liège province of Belgium. It serves a small population of 642 people, reflecting its role in a rural or suburban setting. The plant is situated in the Walloon region, an area characterized by rolling hills and numerous waterways. The plant provides secondary treatment, which is the standard biological treatment stage required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological oxidation and settling to remove organic matter and suspended solids. The plant's designed capacity of 1890 m³/day indicates it has room to accommodate future growth or seasonal variations. Treated effluent from Chawresse is discharged into a local watercourse that ultimately drains into the Meuse River basin. The Meuse flows through Belgium and the Netherlands before reaching the North Sea. The plant's operations help protect the local aquatic environment and downstream ecosystems from pollution, supporting water quality in the region.
