Port Louis nouvelle station du Bourg - Advanced Wastewater Treatment Plant in Port-Louis, Guadeloupe

Port Louis nouvelle station du Bourg is an advanced wastewater treatment plant located in Port-Louis, Guadeloupe, an overseas department of France. The plant serves a population of approximately 4,000 residents, making it a small-scale facility within the island's wastewater infrastructure. Its coastal location places it within 10 km of the Caribbean Sea, which is the ultimate receiving water body for treated effluent. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 7,000 m³/day indicates the plant has room for future growth, while current discharge volume is 713.59 m³/day. As a French facility, it operates under national regulations that transpose EU directives, ensuring high environmental standards. The treated wastewater is discharged into the coastal waters of the Caribbean Sea, which supports diverse marine ecosystems including coral reefs and seagrass beds. The plant plays a crucial role in protecting these sensitive environments from nutrient pollution and pathogens. Guadeloupe's tropical climate and tourism-dependent economy make effective wastewater treatment essential for both ecological health and economic sustainability.

The plant discharges into the Caribbean Sea near Port-Louis, on the northwest coast of Grande-Terre, Guadeloupe. The coastal waters are part of the wider Caribbean basin, which supports ecologically sensitive marine habitats such as coral reefs and mangrove forests. These ecosystems are vulnerable to nutrient enrichment and require effective wastewater treatment to maintain water quality and biodiversity.
