Overview
SOMMAING SUR ECAILLON is an advanced wastewater treatment plant serving Verchain-Maugré in Hauts-de-France, France. It treats wastewater for about 3,792 people with a designed capacity of 4,500 m³/day.
SOMMAING SUR ECAILLON is a wastewater treatment plant located in Verchain-Maugré, within the Valenciennes area of Nord, Hauts-de-France, France. The plant serves a population of approximately 3,792 people and has a designed capacity of 4,500 cubic meters per day, with an average discharge volume of 676.49 m³/day. As an advanced treatment facility, it provides a high level of purification beyond secondary treatment. Operating under the EU Urban Waste Water Treatment Directive 91/271/EEC, the plant is part of France's commitment to stringent wastewater management. For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and the advanced level here exceeds the minimum secondary standard, indicating a focus on nutrient removal or other specific pollutants. The treated effluent is discharged into local watercourses that ultimately drain into the Scheldt River basin, flowing through northern France and Belgium toward the North Sea. This region is characterized by dense river networks and agricultural land, making advanced treatment crucial for protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the Scheldt River basin, which flows through Hauts-de-France and into Belgium before reaching the North Sea. This watershed supports diverse aquatic life and is important for regional water supply and agriculture. Advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
