Overview
Ste Lucie de Porto Vecchio wastewater treatment plant serves Cavallone, Corse, France, treating wastewater from approximately 23,000 people. The plant is located within 50 km of the coast, discharging into the Mediterranean Sea.
The Ste Lucie de Porto Vecchio wastewater treatment plant is located in Cavallone, in the Corse-du-Sud department of Corsica, France. It serves a population of approximately 23,000 people, making it a medium-sized agglomeration under French and EU classification. The plant is situated near the coastal town of Porto-Vecchio, within 50 km of the Mediterranean coastline. As a French wastewater treatment facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving area is designated as sensitive. The treated effluent from the plant ultimately reaches the Mediterranean Sea, likely via local watercourses such as the Stabiacciu River or other coastal streams. The Corsican coastline is ecologically significant, supporting seagrass meadows (Posidonia oceanica) and diverse marine life. Proper wastewater treatment is essential to protect these sensitive coastal ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Mediterranean Sea, likely via small coastal streams near Porto-Vecchio. The Corsican coast hosts ecologically sensitive habitats, including seagrass beds and rocky reefs that support diverse marine species. Nutrient inputs from wastewater can impact water quality and marine biodiversity, making effective treatment critical for preserving the local marine environment.
