Overview
TROIS ILETS ANSE MARETTE wastewater treatment plant serves Les Trois-Îlets, Martinique, France. It treats wastewater from a population of approximately 10,633 and has a designed capacity of 1.00 cubic meters per day.
TROIS ILETS ANSE MARETTE is a wastewater treatment plant located in Les Trois-Îlets, a commune on the Caribbean island of Martinique, an overseas department of France. The plant serves a population of about 10,633, placing it in the small to medium agglomeration category under French and EU regulations. As a facility in an EU overseas territory, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's treated effluent likely discharges into the Caribbean Sea, given its coastal location within 50 km of the coast. Martinique's watersheds drain rapidly from mountainous terrain to the sea, and the plant plays a key role in protecting nearshore marine ecosystems, including coral reefs and seagrass beds, from nutrient pollution and pathogens.
Environmental context
The plant is situated on the island of Martinique, where streams and rivers flow from the central mountains to the Caribbean Sea. The receiving waters are part of the Caribbean basin, a region known for its coral reefs, mangroves, and diverse marine life. Effective wastewater treatment is critical to prevent eutrophication and protect these sensitive coastal ecosystems, which support tourism and fisheries.

As a French facility in an EU overseas territory, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations over 2,000 population equivalent discharging into coastal waters.
For agglomerations of this size in sensitive coastal areas, secondary treatment is standard, often involving biological processes to reduce organic matter and nutrients before marine discharge.
