Luçon Wastewater Treatment Plant - Serving Luçon, Pays de la Loire, France

The Luçon wastewater treatment plant is located in Luçon, a commune in the Vendée department of Pays de la Loire, France. It serves a population of approximately 11,099, placing it in the medium agglomeration category under EU regulations. The plant is situated near the coast, within 50 km of the Atlantic Ocean, and its operations are subject to French national water quality standards. As a facility serving between 10,000 and 15,000 people, the plant is required by the EU Urban Waste Water Treatment Directive (91/271/EEC) to provide at least secondary treatment. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating a scale appropriate for its population served. French regulations under the Water Law and the national sanitation program ensure compliance with discharge standards. The plant discharges treated wastewater into the local hydrological network, which ultimately drains into the Atlantic Ocean via the Vendée River or nearby coastal waters. The region's watershed supports diverse aquatic life and is important for migratory fish species. The plant's proximity to the coast means its effluent quality is critical for protecting marine ecosystems and recreational waters.

The treated effluent from Luçon plant flows into the local river system, part of the Vendée basin, which discharges into the Atlantic Ocean near the Bay of Biscay. This coastal area supports diverse marine life, including fish nurseries and migratory birds. The plant's location within 50 km of the coast underscores the importance of nutrient removal to prevent eutrophication in sensitive coastal waters.
