Overview
Beauvais wastewater treatment plant serves approximately 113,000 people in Hauts-de-France, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Beauvais wastewater treatment plant is a municipal facility located in Beauvais, Oise, Hauts-de-France, France. It serves a population of approximately 113,000, classifying it as a large agglomeration under EU regulations. The plant is situated inland, over 50 km from the coast, and discharges into the local watershed. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) greater than 10,000 are required to have secondary treatment, and those over 150,000 PE must meet tertiary standards in sensitive areas. With a population served of 112,733, the Beauvais plant is expected to provide at least secondary treatment. The directive also mandates monitoring and compliance with discharge standards to protect receiving waters. The plant's treated effluent flows into the Thérain River, a tributary of the Oise River, which eventually joins the Seine River and drains into the English Channel. This waterway supports diverse aquatic life and is important for regional biodiversity. The plant plays a key role in maintaining water quality in the Seine basin, a densely populated and agriculturally active region.
Environmental context
The Beauvais plant discharges into the Thérain River, which flows into the Oise River, a major tributary of the Seine River. The Seine ultimately empties into the English Channel. This watershed supports diverse aquatic ecosystems and is a critical resource for drinking water, agriculture, and recreation in northern France. The plant's operations help protect downstream habitats from nutrient pollution and pathogens.
