Overview
ST GEORGES OLERON CHAUCRE wastewater treatment plant serves Chaucre in Nouvelle-Aquitaine, France. It treats wastewater for approximately 14,575 people under the EU Urban Waste Water Treatment Directive.
ST GEORGES OLERON CHAUCRE is a wastewater treatment plant located in Chaucre, on the Île d'Oléron in the Nouvelle-Aquitaine region of France. The plant serves a population of approximately 14,575 people, classifying it as a medium agglomeration under EU regulations. Its location on the Atlantic coast places it in a sensitive environmental area. As a French plant serving over 10,000 population equivalent, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For coastal discharges in sensitive areas, more stringent treatment may be mandated to protect marine ecosystems. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized for its service population. The treated effluent is discharged into the Atlantic Ocean, which surrounds the Île d'Oléron. The island's coastal waters support diverse marine life, including shellfish beds and migratory fish species. Proper treatment is essential to prevent nutrient pollution and protect the region's ecological and economic resources, such as tourism and fishing.
Environmental context
The plant discharges into the Atlantic Ocean near the Île d'Oléron, a coastal island in the Pertuis d'Antioche strait. This area supports rich marine biodiversity, including seagrass beds and shellfish fisheries. The downstream environment is influenced by tidal flows and is ecologically sensitive to nutrient inputs, making advanced wastewater treatment important for preserving water quality.
Frequently asked questions
The plant is located in Chaucre, on the Île d'Oléron in the Nouvelle-Aquitaine region of France, near the Atlantic coast.
The plant serves approximately 14,575 people, classifying it as a medium-sized agglomeration under EU regulations.
The treated effluent is discharged into the Atlantic Ocean, which surrounds the Île d'Oléron. The plant's coastal location requires compliance with stringent discharge standards to protect marine ecosystems.
As a French plant serving over 10,000 population equivalent, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and may require tertiary treatment in sensitive coastal areas.
For agglomerations of this size, the EU Urban Waste Water Treatment Directive requires at least secondary treatment. In coastal sensitive areas, additional nutrient removal may be necessary to prevent eutrophication.
