GOzEE cite verte Wastewater Treatment Plant, Montigny-le-Tilleul, Hainaut

GOzEE cite verte is a former wastewater treatment plant located in Montigny-le-Tilleul, within the Hainaut province of Belgium. The facility served a small population of 779 people before its closure, reflecting its role in a modest residential or semi-rural catchment area. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Although the plant is now closed, its design and operation would have complied with national regulations transposing the directive, ensuring organic matter reduction before discharge. The treated effluent was likely discharged into a local watercourse within the Scheldt basin, which ultimately drains into the North Sea. Possibly through connection to a larger regional facility, reducing local environmental impact.

The plant's discharge would have entered a local stream in the Hainaut region, part of the Scheldt River basin. The Scheldt flows through Belgium and the Netherlands before reaching the North Sea, an ecologically sensitive area supporting diverse aquatic life and important for migratory birds. The closure of this small plant likely reduces nutrient loading in the local watershed, benefiting downstream water quality.
