BRETEUIL SUR NOYE Wastewater Treatment Plant, Breteuil, Hauts-de-France

The BRETEUIL SUR NOYE wastewater treatment plant is located in Breteuil, a commune in the Oise department of the Hauts-de-France region in northern France. The facility serves a population of approximately 7,046 residents, classifying it as a small to medium agglomeration under European Union regulations. The plant is situated on Rue Basse Saint-Cyr, within the Clermont arrondissement. As a French wastewater facility, the plant 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 appropriate treatment before discharge into freshwater bodies. The plant is expected to meet these regulatory standards to protect local water quality. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Noye River, a tributary of the Avre and part of the Seine basin. The Seine River flows through Paris and into the English Channel, making the plant's operations important for downstream water quality. The region's aquatic ecosystems benefit from proper wastewater treatment, supporting biodiversity in the river systems.

The plant discharges into the Noye River, which flows into the Avre and then the Seine River, eventually reaching the English Channel. This watershed supports diverse aquatic life and is an important ecological corridor in northern France. Proper treatment helps maintain water quality for downstream communities and habitats, including sensitive areas in the Seine estuary.
