VIC SUR SEILLE Wastewater Treatment Plant, Vic-sur-Seille, Grand Est

VIC SUR SEILLE is an advanced wastewater treatment plant located in Vic-sur-Seille, a commune in the Moselle department of the Grand Est region, France. The plant serves a population of 1,250 and has a designed capacity of 2,100 cubic meters per day, with an average discharge volume of 223 cubic meters per day. As an advanced treatment facility, VIC SUR SEILLE 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 (under 2,000 population equivalent), the directive requires appropriate treatment, and France implements this through national regulations that often mandate advanced treatment in sensitive areas. The plant discharges treated effluent into the local watershed, which ultimately drains into the Seille River, a tributary of the Moselle River. The Moselle flows into the Rhine, one of Europe's major rivers, before reaching the North Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the Rhine basin.

The plant discharges into the Seille River, which flows into the Moselle River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic life and serving as a critical migratory corridor for fish species. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters, including the Rhine Delta and the North Sea.
