CARBET bourg Wastewater Treatment Plant, Le Carbet, Martinique

CARBET bourg is a municipal wastewater treatment plant located in Le Carbet, a commune on the Caribbean coast of Martinique, an overseas department of France. The plant serves a population of approximately 1,364 people and has a designed capacity of 1,800 m³/day, with an average daily discharge of 243.34 m³/day. As a secondary treatment facility, CARBET bourg provides biological treatment to reduce organic matter and suspended solids. Under French and EU regulations, secondary treatment is the standard for discharges into coastal waters, and the plant's operation aligns with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The plant's treated effluent is discharged into the Caribbean Sea, likely via a local watercourse or outfall. The coastal waters of Martinique support diverse marine ecosystems, including coral reefs and seagrass beds, which are sensitive to nutrient and pollutant inputs. Proper treatment helps protect these habitats and maintain water quality for tourism and fisheries.

The plant discharges into the Caribbean Sea near the coast of Le Carbet. The local watershed drains volcanic slopes into the sea, supporting nearshore marine habitats such as coral reefs and seagrass beds. These ecosystems are sensitive to nutrient enrichment and require effective wastewater treatment to prevent eutrophication and maintain biodiversity.
