MORTAGNE DU NORD is an advanced wastewater treatment plant located in Maulde, within the Valenciennes area of Nord, Hauts-de-France, France. The plant serves a population of 4,643 and has a designed capacity of 5,850 m³/day, with an average daily discharge volume of 828.3 m³/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 (under 10,000 PE), the directive requires appropriate treatment, and the plant's advanced level indicates compliance with sensitive area requirements. The plant discharges treated effluent into local watercourses that ultimately drain into the Scheldt River basin, which flows through Belgium and the Netherlands to the North Sea. Its advanced treatment helps protect downstream ecosystems, including the Scheldt estuary, a vital habitat for migratory birds and aquatic life.
Environmental context
The plant discharges into the Scheldt River basin, which flows through northern France, Belgium, and the Netherlands before reaching the North Sea. The Scheldt estuary is an ecologically sensitive area supporting diverse aquatic life and migratory bird populations. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters.
