PORTETS 2 is a municipal wastewater treatment plant located in Tabanac, within the Gironde department of Nouvelle-Aquitaine, France. The facility serves a population of around 4,087 and is part of the region's wastewater infrastructure managed under French and EU regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 7,500 m³/day and an average discharge volume of 729.11 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Treated wastewater from PORTETS 2 is discharged into the local water system, which ultimately drains into the Garonne River and then the Gironde estuary, a major ecological and economic waterway in southwestern France. The estuary supports diverse aquatic life and is an important migratory corridor for fish species.
Environmental context
The plant discharges into the Garonne River basin, which flows into the Gironde estuary and then the Atlantic Ocean. The Gironde estuary is one of Europe's largest and most ecologically significant estuaries, supporting diverse fish populations, including migratory species such as salmon and eels. The region's temperate climate and agricultural land use require careful management of nutrient loads to prevent eutrophication in downstream waters.
