Overview
MARBAIS Pre Saint Pierre is a closed secondary treatment plant in Villers-la-Ville, Belgium, serving 150 people. It discharged 26.81 m³/day with a design capacity of 310 m³/day.
MARBAIS Pre Saint Pierre is a former wastewater treatment plant located in the Marbais district of Villers-la-Ville, in the Brabant wallon province of Belgium. It served a small population of 150 people, reflecting its role as a local facility for a rural community. The plant provided secondary treatment, a standard biological process that removes organic matter and suspended solids. Although now closed, it had a design capacity of 310 m³/day and discharged an average volume of 26.81 m³/day. As a Belgian facility, it operated under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The treated effluent was discharged into local watercourses that ultimately drain into the Scheldt basin, contributing to the region's surface water network. The plant's closure suggests that wastewater from this area is now managed by a larger, more centralized facility, improving treatment efficiency and environmental protection.
Environmental context
The plant's discharge entered local streams within the Scheldt River basin, which flows through Belgium and the Netherlands before reaching the North Sea. The surrounding area is part of the Walloon region's rural landscape, where small water bodies support aquatic life and agricultural activities. Proper treatment of wastewater is essential to prevent nutrient enrichment and protect downstream ecosystems.
