Overview
YCHOUX wastewater treatment plant in Ychoux, Nouvelle-Aquitaine, France, serves 1,550 people with advanced treatment. It discharges 276.52 m³/day and has a designed capacity of 2,500 m³/day.
The YCHOUX wastewater treatment plant is located in the commune of Ychoux, within the Landes department of Nouvelle-Aquitaine, southwestern France. It serves a population of approximately 1,550 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated inland, more than 10 km from the Atlantic coast, and operates within the region's municipal wastewater infrastructure. The facility employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,500 m³/day and an average daily discharge of 276.52 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The plant's advanced treatment likely includes nutrient removal to protect sensitive downstream environments. Treated effluent from YCHOUX is discharged into local watercourses that drain toward the Atlantic Ocean via the coastal lakes and rivers of the Landes region. The area is ecologically significant, supporting diverse aquatic habitats and migratory species. The plant's advanced treatment helps minimize nutrient loading and protect the water quality of downstream ecosystems, including the nearby Étang de Cazaux et de Sanguinet and the Bay of Biscay.
Environmental context
The YCHOUX plant discharges into the watershed of the Landes region, which ultimately drains into the Atlantic Ocean via coastal lakes such as Étang de Cazaux et de Sanguinet and the Bay of Biscay. This area supports diverse aquatic life and is an important corridor for migratory fish. The advanced treatment level helps reduce nutrient pollution, protecting the sensitive coastal and marine environments downstream.
