PAGNY SUR MOSELLE Wastewater Treatment Plant, Pagny-sur-Moselle, Grand Est

PAGNY SUR MOSELLE is an advanced wastewater treatment plant located in Pagny-sur-Moselle, a commune in the Meurthe-et-Moselle department of the Grand Est region, France. The plant serves a population of approximately 4,450 and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 793.87 cubic meters per day. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. In France, wastewater treatment plants are regulated under national legislation that transposes the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and advanced treatment is often implemented in sensitive areas to protect receiving waters. The plant discharges treated water into the Moselle River, a major tributary of the Rhine. The Moselle flows north through France, Luxembourg, and Germany before joining the Rhine at Koblenz. The Rhine basin is one of Europe's most important river systems, supporting diverse aquatic life and providing drinking water for millions. The plant's advanced treatment helps reduce nutrient loads that could contribute to eutrophication in downstream water bodies.

The plant discharges into the Moselle River, which flows into the Rhine and ultimately reaches the North Sea. The Moselle-Rhine system supports diverse aquatic ecosystems, including fish species such as salmon and eel. Advanced treatment at this plant helps minimize nutrient pollution, protecting water quality in the Moselle and downstream environments.
