The Auvers-sur-Oise wastewater treatment plant is located in the Val-d'Oise department of Île-de-France, France, serving the commune of Auvers-sur-Oise and surrounding areas. With a population equivalent of around 16,300, it is classified as a medium-sized agglomeration under French regulations. As a French wastewater facility, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards set by the French Ministry of Ecology, ensuring compliance with water quality objectives for the receiving environment. The treated wastewater is discharged into the Oise River, which flows into the Seine River and ultimately reaches the English Channel. The plant plays a key role in protecting the Oise and Seine river ecosystems, supporting aquatic life and recreational uses downstream.
Environmental context
The plant discharges into the Oise River, a major tributary of the Seine River, which flows through Paris and into the English Channel.
