Trivières is a wastewater treatment plant located in La Louvière, within the Hainaut province of Belgium. The facility serves a population of around 13,187, placing it in the medium agglomeration category under EU classifications. As a Belgian plant, Trivières operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant discharges treated effluent into local waterways that ultimately drain into the Scheldt River basin, which flows through Belgium and the Netherlands into the North Sea. The Scheldt estuary supports diverse aquatic life and is an important ecological corridor for migratory fish species.
Environmental context
The treated effluent from Trivières enters the Haine River, a tributary of the Scheldt River. The Scheldt flows through Belgium and the Netherlands before discharging into the North Sea. This watershed supports diverse aquatic ecosystems and is an important migratory corridor for fish. The region's industrial and agricultural activities place additional pressure on water quality, making effective treatment essential.
