HASPARREN Minhotz Wastewater Treatment Plant - Ayherre, Nouvelle-Aquitaine

HASPARREN Minhotz is a wastewater treatment plant located in Ayherre, within the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, France. The facility serves a population of approximately 6,890 people, placing it in the small-to-medium agglomeration category under European Union classification. As a French plant, HASPARREN Minhotz 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 plant's designed capacity is 1.00 cubic meters per day, indicating a modest scale appropriate for its service area. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Adour River basin, flowing toward the Bay of Biscay in the Atlantic Ocean. This region supports diverse aquatic life and is important for migratory fish species such as salmon and eel.

The plant discharges into the Adour River basin, which flows through the Pyrénées-Atlantiques region before reaching the Bay of Biscay. The downstream environment includes ecologically sensitive estuarine and coastal habitats that support diverse aquatic life, including migratory fish species. Proper treatment is essential to protect water quality in this Atlantic drainage system.
