Overview
LATRESNE 2 is a secondary wastewater treatment plant in Latresne, Nouvelle-Aquitaine, France, serving about 4,862 people. It discharges treated water into the local watershed, ultimately reaching the Garonne River and the Atlantic Ocean.
LATRESNE 2 is a municipal wastewater treatment facility located in Latresne, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of approximately 4,862 residents and operates under secondary treatment, which is the standard biological treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The plant has a designed capacity of 6,000 cubic meters per day and currently treats an average daily volume of about 867 cubic meters, indicating ample reserve capacity. As a facility in France, it is subject to national regulations transposing the EU directive, which mandates secondary treatment for discharges into freshwater and estuaries from agglomerations above 2,000 population equivalent. The treated effluent from LATRESNE 2 is discharged into the local watercourse, which flows into the Garonne River, a major river in southwestern France. The Garonne drains into the Gironde estuary and then the Bay of Biscay in the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Garonne basin, which supports diverse aquatic life and is used for recreation and agriculture.
Environmental context
LATRESNE 2 discharges into a tributary of the Garonne River, which flows through the Gironde estuary into the Bay of Biscay. The Garonne basin is ecologically significant, supporting migratory fish species such as Atlantic salmon and European eel. The estuary is a vital nursery for marine life. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this dynamic coastal-inland system.
