Overview
STEP du Port is a municipal wastewater treatment plant serving Le Port, La Réunion, France. It handles a population equivalent of approximately 67,827 under the EU Urban Waste Water Treatment Directive.
STEP du Port is a municipal wastewater treatment plant located in the industrial zone of Le Port, on the island of La Réunion, an overseas department of France. The plant serves a population equivalent of approximately 67,827, placing it in the medium-to-large agglomeration category under French and European regulations. As a French facility in an EU 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. The directive also mandates more advanced treatment if the discharge enters sensitive areas, such as coastal zones or coral reef ecosystems common around La Réunion. The treated effluent from STEP du Port is discharged into the local watershed, which ultimately drains into the Indian Ocean. La Réunion's coastal waters support diverse marine life, including coral reefs and protected species. Proper treatment is critical to prevent nutrient pollution and protect the island's fragile coastal ecosystems.
