IDRON OUSSE SENDETS INTERCOMMUNALE is a wastewater treatment plant located in Idron, a commune in the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of approximately 7,860, placing it in the small-to-medium agglomeration category under EU classification. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The directive also mandates appropriate treatment to meet quality standards for receiving waters, with more stringent requirements for sensitive areas. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Gave de Pau river and then the Adour river before reaching the Bay of Biscay in the Atlantic Ocean. The downstream environment supports diverse aquatic life and is part of a broader ecological network important for migratory fish species.
