Overview
SAINT LOUIS STEU DU GOL is a wastewater treatment plant serving approximately 76,000 people in Saint-Louis, La Réunion, France. The plant discharges into the local watershed, contributing to the island's water management infrastructure.
SAINT LOUIS STEU DU GOL is a municipal wastewater treatment plant located in Saint-Louis, on the island of La Réunion, an overseas department of France. Serving a population of around 76,000, the plant is a key component of the region's sanitation infrastructure, handling wastewater from the urban area of Saint-Louis and surrounding communities. As a French overseas territory, the plant operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas, such as coastal zones or coral reef ecosystems, which are prevalent in La Réunion. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Indian Ocean. La Réunion's coastal waters support diverse marine life, including coral reefs and protected species. Proper treatment is essential to prevent nutrient pollution and protect the island's unique aquatic ecosystems.
Environmental context
The plant discharges into the local river system on La Réunion, which flows into the Indian Ocean. The island's coastal waters are ecologically sensitive, supporting coral reefs and diverse marine biodiversity. Effective wastewater treatment is critical to prevent eutrophication and protect these fragile ecosystems from nutrient overload and contamination.
