SAUBION communale Wastewater Treatment Plant, Saubion, Nouvelle-Aquitaine

SAUBION communale is a municipal wastewater treatment plant located in Saubion, a commune in the Landes department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of approximately 2,100 residents and is situated within the Lotissement Les Allées area near Dax. It operates under France's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for wastewater collection and treatment. The plant employs advanced treatment processes, going beyond the secondary treatment required by the EU directive for agglomerations of this size. Its designed capacity is 2,200 m³ per day, with an average daily discharge of 374.64 m³, indicating significant spare capacity for future growth. The facility is located within 10 km of the Atlantic coast, placing it in a sensitive coastal zone where advanced treatment helps protect marine water quality. Treated effluent from the plant likely discharges into local watercourses that flow toward the Atlantic Ocean, contributing to the health of coastal ecosystems. The plant plays a key role in safeguarding the region's water resources, supporting both environmental quality and public health in this part of the Landes region.

The plant is situated near the Atlantic coast of southwestern France, within the Adour-Garonne basin. Treated wastewater likely flows into small coastal streams that drain into the Bay of Biscay, a productive marine environment supporting diverse fish and bird populations. The advanced treatment level helps minimize nutrient loading and protects sensitive coastal habitats from eutrophication.
