Overview
LE BOUSQUET D ORB LUNAS wastewater treatment plant serves Lunas-les-Châteaux in Occitanie, France. It handles a population equivalent of 5,800 and operates under EU Urban Waste Water Treatment Directive standards.
LE BOUSQUET D ORB LUNAS is a wastewater treatment plant located in Lunas-les-Châteaux, within the Hérault department of Occitanie, southern France. The facility serves a population equivalent of approximately 5,800 people, classifying it as a small to medium agglomeration under European Union classification. As a French plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with national and European standards for effluent quality. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Mediterranean Sea via the Orb River. The Orb River supports diverse aquatic life and is an important water resource for the region. The plant's inland location, over 50 km from the coast, reduces direct marine impact but still requires careful management to protect downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Orb River basin, which drains into the Mediterranean Sea near Valras-Plage. The Orb River supports a variety of fish species and provides habitat for migratory birds. The downstream environment includes coastal lagoons and wetlands that are ecologically sensitive, requiring effective nutrient removal to prevent eutrophication.
