Overview
Le Porge La Jenny is an advanced wastewater treatment plant in Le Porge, Nouvelle-Aquitaine, France. It serves a population of 4,000 with a designed capacity of 4,000 m³/day and discharges treated effluent near the Atlantic coast.
Le Porge La Jenny is an advanced wastewater treatment plant located in Le Porge, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant serves a population equivalent of 4,000 and has a designed capacity of 4,000 cubic meters per day, with an average discharge volume of 713.59 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, but the plant's advanced level indicates it operates in a sensitive area or under additional local requirements. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Arcachon Bay or nearby coastal waters. The proximity to the coast (within 10 km) means the plant plays a key role in protecting marine water quality and supporting the region's tourism and aquaculture industries.
Environmental context
The plant discharges into the coastal watershed of the Arcachon Bay, a semi-enclosed marine inlet connected to the Atlantic Ocean. This area supports diverse aquatic life, including seagrass beds and shellfish fisheries, and is an important migratory corridor for birds. The advanced treatment level helps minimize nutrient loading and protects the ecological balance of the bay and adjacent coastal waters.
Frequently asked questions
Le Porge La Jenny is located in Le Porge, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant's address is Marguerite 17, Le Porge, 33680.
The plant serves a population equivalent of 4,000 people, typical for a small agglomeration in the region.
The plant discharges treated effluent into the local watershed, which flows toward the Atlantic coast near the Arcachon Bay. The advanced treatment ensures high-quality effluent to protect the sensitive coastal environment.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection, treatment, and discharge. For agglomerations of 4,000 population equivalent, secondary treatment is required, but the plant's advanced level indicates compliance with stricter requirements for sensitive areas.
In France, plants serving agglomerations between 2,000 and 10,000 population equivalent are generally required to have secondary treatment under the EU directive. However, if the receiving water is sensitive (e.g., coastal or eutrophic), advanced treatment with nutrient removal may be mandated.
