Environmental context
The plant discharges into the Tech River basin, which flows eastward through the Pyrénées-Orientales and empties into the Mediterranean Sea near Argelès-sur-Mer. This coastal watershed supports diverse aquatic habitats, including riparian zones and estuarine environments that are important for migratory fish and bird species. The secondary treatment provided helps reduce nutrient and organic loads, mitigating eutrophication risks in the downstream coastal waters.
