Moliets et Maa Wastewater Treatment Plant, Moliets-et-Maâ, Nouvelle-Aquitaine

Moliets et Maa is a wastewater treatment plant located in Moliets-et-Maâ, a commune in the Landes department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of around 15,500, placing it in the medium agglomeration category under EU classification. As a French facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a scale appropriate for its population served. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the coastal rivers of the Landes region. The area is ecologically sensitive, supporting diverse aquatic life and important migratory corridors for fish species. The plant plays a key role in protecting the water quality of downstream environments, including coastal lagoons and the Bay of Biscay.

The plant discharges into the local river system, which flows into the Atlantic Ocean along the Landes coast. This region features coastal lagoons and wetlands that support diverse aquatic life and serve as important migratory corridors for fish and birds. The plant's treatment helps protect these sensitive downstream ecosystems from nutrient pollution and pathogens.
