ILE D YEU Les Roses, L'Île-d'Yeu

Overview

ILE D YEU Les Roses wastewater treatment plant serves L'Île-d'Yeu, France, treating wastewater for approximately 8,450 residents. The facility is located on an island in the Pays de la Loire region.

ILE D YEU Les Roses is a wastewater treatment plant located on the island of L'Île-d'Yeu, off the Atlantic coast of France in the Pays de la Loire region. The plant serves a population of approximately 8,450 residents, primarily in the town of Port-Joinville. As a facility on a small island, it plays a critical role in protecting the local marine environment. The plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for wastewater treatment based on population size and receiving water sensitivity. For agglomerations between 2,000 and 10,000 population equivalent, the directive requires secondary treatment, with more stringent requirements if the discharge is into sensitive areas. The island's coastal location likely classifies the receiving waters as sensitive, potentially necessitating tertiary treatment to reduce nutrients. The treated effluent is discharged into the Atlantic Ocean, which surrounds L'Île-d'Yeu. The island's coastal waters support diverse marine life, including fish, shellfish, and seabirds. Proper treatment is essential to prevent eutrophication and maintain water quality for tourism and fishing, which are vital to the local economy.

Environmental context

The plant discharges into the Atlantic Ocean off the coast of L'Île-d'Yeu, an island in the Bay of Biscay. The surrounding marine environment supports diverse ecosystems, including seagrass beds and rocky reefs that provide habitat for fish and crustaceans. The area is also important for migratory seabirds. Effective wastewater treatment is crucial to prevent nutrient pollution that could lead to algal blooms and oxygen depletion, protecting both ecological health and the island's tourism-dependent economy.

Frequently asked questions

The plant is located on the island of L'Île-d'Yeu, off the Atlantic coast of France in the Pays de la Loire region. Its address is Rue des Roses, Les Roses, Port-Joinville, L'Île-d'Yeu.

The plant serves approximately 8,450 residents, primarily in the town of Port-Joinville on L'Île-d'Yeu.

The treated effluent is discharged into the Atlantic Ocean, which surrounds L'Île-d'Yeu. The plant's coastal location means the discharge directly affects marine waters.

As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of 8,450 people, secondary treatment is required, and due to the coastal sensitive area, tertiary treatment may be mandated to reduce nutrients.

Under the EU directive, plants serving between 2,000 and 10,000 population equivalent typically require secondary treatment. In coastal sensitive areas, additional nutrient removal (tertiary treatment) is often required to protect marine ecosystems.
