Baie Mahault Trioncelle is a wastewater treatment plant located in Baie-Mahault, on the island of Basse-Terre in Guadeloupe, an overseas department of France. The plant serves a population of about 15,620 residents, making it a medium-sized agglomeration under French and EU regulations. As a facility in a French overseas territory, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size.

Guadeloupe's coastal ecosystems include mangroves, seagrass beds, and coral reefs, which are sensitive to nutrient pollution. Proper treatment is essential to protect these marine habitats and support biodiversity.
Environmental context
The plant discharges into the watershed of Basse-Terre, which drains into the Caribbean Sea. This coastal environment supports diverse marine life, including coral reefs and mangrove forests that provide critical nursery habitats for fish and protect shorelines. Nutrient loading from wastewater can lead to eutrophication and algal blooms, threatening these ecosystems.
