Overview
LONGUYON_54 is an advanced wastewater treatment plant in Longuyon, Grand Est, France, serving approximately 2,850 people. It discharges 508.44 m³/day of treated effluent.
LONGUYON_54 is a municipal wastewater treatment plant located in Longuyon, within the Grand Est region of France. The facility serves a population of approximately 2,850 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the town of Noërs along the D 643 road. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 5,333 m³/day and currently discharges 508.44 m³/day of treated wastewater, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Meuse River basin. The Meuse flows through France, Belgium, and the Netherlands before reaching the North Sea. The advanced treatment level helps protect downstream aquatic ecosystems and supports the ecological health of the Meuse River and its tributaries.
Environmental context
The plant discharges into the Meuse River basin, which flows through the Grand Est region and eventually reaches the North Sea. The Meuse supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the river and its estuary.
