BOUXIERES AUX DAMES Wastewater Treatment Plant, Frouard, Grand Est, France

BOUXIERES AUX DAMES is an advanced wastewater treatment plant located in Frouard, in the Grand Est region of France. The plant serves a population of approximately 2,000 people and has a designed capacity of 4,500 cubic meters per day, with a current discharge volume of 356.80 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment, but the plant's advanced level indicates it likely discharges into a sensitive area or is designed for high-quality effluent. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Moselle River and then the Rhine River. This region is part of the Rhine basin, a major European waterway that supports diverse aquatic ecosystems and provides drinking water for millions. The advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Moselle River basin, which flows into the Rhine River and eventually the North Sea. The Moselle is an important river for biodiversity, supporting fish species such as salmon and trout. Advanced treatment at this plant helps reduce nutrient loads, preventing eutrophication in downstream waters and protecting the ecological balance of the Rhine delta.
