BRIEY_54 Wastewater Treatment Plant, Val de Briey, Grand Est, France

BRIEY_54 is a municipal wastewater treatment plant located in Val de Briey, within the Meurthe-et-Moselle department of the Grand Est region in northeastern France. The plant serves a population of approximately 15,600 residents, classifying it as a medium-sized agglomeration under European Union standards. As a French wastewater facility, BRIEY_54 operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires appropriate collection systems and treatment to protect receiving water bodies. Plants of this scale in France typically employ biological treatment stages to meet regulatory standards. The treated effluent from BRIEY_54 is discharged into the local watershed, which ultimately drains into the Moselle River basin. The Moselle flows northward through Luxembourg and Germany before joining the Rhine River, a major European waterway. This discharge contributes to the overall water quality management of the Rhine basin, which supports diverse aquatic ecosystems and serves as a critical water resource for multiple countries.

The plant discharges into the Moselle River basin, which flows into the Rhine River and eventually the North Sea. This watershed supports diverse aquatic life, including fish species such as salmon and trout, and is an important ecological corridor in Western Europe. The Grand Est region's mixed urban and agricultural land use requires careful nutrient management to prevent eutrophication in downstream waters.
