Trois Rivieres Robin Wastewater Treatment Plant, Trois-Rivières, Guadeloupe

Trois Rivieres Robin is an advanced wastewater treatment plant located in Trois-Rivières, on the island of Basse-Terre in Guadeloupe, an overseas department of France. The plant serves a population of approximately 2,000 residents and has a designed capacity of 2,500 m³/day, with a current discharge volume of 356.80 m³/day. As an advanced treatment facility, Trois Rivieres Robin provides a higher level of pollutant removal than secondary treatment, which is particularly important for protecting sensitive coastal environments. The plant operates under French regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into coastal waters. The plant's treated effluent is discharged into the coastal waters of the Caribbean Sea near Grand Anse. This area supports diverse marine life, including coral reefs and seagrass beds, which are sensitive to nutrient pollution. The advanced treatment helps minimize ecological impact on this tropical marine ecosystem.

The plant discharges into the Caribbean Sea near Grand Anse, a coastal area on the southwestern coast of Basse-Terre. The receiving waters are part of the wider Caribbean basin, which supports coral reefs, mangroves, and seagrass habitats. These ecosystems are sensitive to nutrient enrichment and require high-quality effluent to maintain ecological balance.
