Overview
SAINT JOSEPH REUNION is a closed secondary treatment plant in Saint-Joseph, La Réunion, France. It served the local community before ceasing operations.
SAINT JOSEPH REUNION is a former wastewater treatment plant located in Saint-Joseph, on the island of La Réunion, an overseas department of France. The plant provided secondary treatment for the local population before its closure. As a French facility, the plant operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant's closure means wastewater from Saint-Joseph is now handled by other regional infrastructure. The plant's discharge would have entered local waterways on La Réunion, an island in the Indian Ocean with sensitive coastal and marine ecosystems. The island's rivers drain into the surrounding ocean, supporting coral reefs and diverse marine life.
Environmental context
La Réunion's rivers flow from volcanic highlands to the Indian Ocean, supporting unique freshwater and coastal ecosystems. The island's watersheds are ecologically sensitive, with endemic species and coral reefs downstream. Proper wastewater treatment is critical to prevent nutrient pollution and protect marine biodiversity.

The plant is located in Saint-Joseph, on the island of La Réunion, an overseas department of France in the Indian Ocean.
The plant provided secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive for most agglomerations.
The plant is listed as closed, meaning it no longer operates. Wastewater from Saint-Joseph is now likely treated at other regional facilities.
The directive requires secondary treatment for all discharges from agglomerations above 2,000 population equivalent, and more stringent treatment in sensitive areas. French overseas departments follow these standards.
The plant's treated effluent would have discharged into local waterways, eventually reaching the Indian Ocean. Proper treatment helps protect coastal ecosystems and coral reefs around La Réunion.
