BAGNERES DE LUCHON Wastewater Treatment Plant, Bagnères-de-Luchon, Occitanie

The BAGNERES DE LUCHON wastewater treatment plant is located in Bagnères-de-Luchon, a commune in the Haute-Garonne department of Occitanie, southwestern France. The plant serves a population of around 11,091 people, placing it in the medium agglomeration category under EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with national and EU standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River via the Pique River. The Garonne flows through southwestern France and into the Gironde estuary, supporting diverse aquatic life and providing water for agriculture and communities. The plant plays a key role in protecting this important river system from pollution.

The plant discharges into the Pique River, a tributary of the Garonne River. The Garonne flows through the Pyrenees foothills and eventually reaches the Gironde estuary on the Atlantic coast. This watershed supports a range of aquatic species and is ecologically sensitive due to its mountainous headwaters and downstream agricultural uses. The plant's operation helps maintain water quality in this important regional waterway.
