CAYENNE LES JARDINS CREOLES Wastewater Treatment Plant, Remire-Montjoly, French Guiana

CAYENNE LES JARDINS CREOLES is a wastewater treatment plant located in Remire-Montjoly, a suburb of Cayenne in French Guiana. The plant serves a small population of 200 people and operates with secondary treatment, which is typical for small communities in the region. As a facility in French Guiana, an overseas department of France, the plant is subject to French and European Union wastewater regulations. The EU Urban Waste Water Treatment Directive (91/271/EEC) requires secondary treatment for agglomerations of this size, though smaller plants may have adapted requirements. The plant has a designed capacity of 200 m³/day and currently discharges 35.68 m³/day of treated effluent. The treated wastewater is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The plant's proximity to the coast (within 10 km) means its effluent enters a sensitive coastal environment. The surrounding area includes mangrove ecosystems and estuaries that support diverse aquatic life, making proper treatment essential for ecological protection.

The plant discharges into the coastal watershed near Cayenne, which flows into the Atlantic Ocean. This region features mangrove forests and estuarine habitats that serve as nurseries for fish and crustaceans. The proximity to the coast means that even secondary-treated effluent can impact sensitive marine ecosystems, particularly if nutrient levels are not carefully managed. The local watershed also supports migratory bird species and contributes to the overall health of the Guiana Shield coastal zone.
