SAINS DU NORD Wastewater Treatment Plant, Ramousies, Hauts-de-France

The SAINS DU NORD wastewater treatment plant is located in Ramousies, a commune in the Nord department of Hauts-de-France, France. The facility serves a population of approximately 1,833 and is designed to handle a capacity of 4,500 cubic meters per day, with an average discharge volume of 327 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a French facility, it operates under national regulations transposing the EU directive, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into the local watershed, which ultimately drains into the North Sea via the Scheldt basin. The region's water bodies support diverse aquatic life and are important for both ecological balance and human use. The plant's advanced treatment helps minimize nutrient loading and protect downstream water quality.

The plant discharges into the local water network within the Scheldt basin, which flows through northern France and Belgium before reaching the North Sea. This watershed supports a variety of fish species and migratory birds. The advanced treatment at SAINS DU NORD reduces nutrient pollution, helping to prevent eutrophication in downstream rivers and coastal zones.
