Overview
SAINT JUST EN CHAUSSEE wastewater treatment plant serves Valescourt, Hauts-de-France, France. It treats wastewater from a population of approximately 10,500.
The SAINT JUST EN CHAUSSEE wastewater treatment plant is located in Valescourt, within the Oise department of Hauts-de-France, France. It serves a population of approximately 10,500 people, classifying it as a medium-sized agglomeration under French and European regulations. As a plant in France, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The treated effluent is discharged into local watercourses that eventually drain into the Seine River basin, which flows into the English Channel. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into the local watershed within the Seine River basin, which ultimately flows into the English Channel. The Seine basin supports diverse aquatic life and is an important ecological corridor. Downstream areas include estuaries and coastal zones that are sensitive to nutrient loading, making effective wastewater treatment crucial for preventing eutrophication and maintaining water quality.
