Taillandier Wastewater Treatment Plant, Presles, Hainaut, Belgium

Taillandier is a former wastewater treatment plant located in Presles, a village within the municipality of Aiseau-Presles in the Hainaut province of Wallonia, Belgium. The plant served a population of 1,710 and was designed with a capacity of 2,250 cubic meters per day, with an average discharge volume of 305.66 cubic meters per day. It provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive for smaller agglomerations. As a closed facility, Taillandier no longer operates. In Belgium, wastewater treatment plants are regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations above 2,000 population equivalent (PE) discharging into freshwater. For smaller plants like Taillandier, appropriate treatment is required to protect receiving waters. The plant discharged treated water into local streams that eventually flow into the Sambre River, a tributary of the Meuse River. The Meuse basin supports diverse aquatic life and is an important water resource for Belgium and the Netherlands. The closure of this plant may have improved overall treatment efficiency in the region.

Taillandier plant discharged into local watercourses that drain into the Sambre River, which flows into the Meuse River. The Meuse basin is a major European river system supporting diverse aquatic ecosystems and providing drinking water for millions. The region's watershed is sensitive to nutrient pollution, and secondary treatment helps reduce organic load and protect downstream habitats.
