ST AUBIN EN BRAY Wastewater Treatment Plant, Lachapelle-aux-Pots, Hauts-de-France

ST AUBIN EN BRAY is a wastewater treatment plant located in Lachapelle-aux-Pots, within the Oise department of Hauts-de-France, France. The plant serves a population of about 6,416 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a French facility, it operates under national regulations that transpose EU directives, ensuring compliance with environmental standards for wastewater treatment. Under the EU UWWTD, agglomerations with a population equivalent (PE) between 2,000 and 10,000 are required to provide appropriate treatment, typically secondary treatment or equivalent. It is expected to meet these regulatory requirements. The plant's design and operation are overseen by local authorities, with permits issued by the French water agencies. The treated effluent is discharged into local watercourses that eventually flow into the Seine River basin, which drains into the English Channel. The plant plays a crucial role in protecting the local aquatic environment, including the Oise River and its tributaries, which support diverse freshwater ecosystems. Proper treatment helps maintain water quality for downstream communities and habitats.

The plant discharges into the Oise River basin, a tributary of the Seine River, which flows into the English Channel. The Seine basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. The plant's operations help protect downstream water quality in the Oise and Seine rivers, which are important for biodiversity and human use.
