Olmeto littoral Wastewater Treatment Plant, Olmeto Plage, Corsica

Olmeto littoral is an advanced wastewater treatment plant located in Olmeto Plage, on the island of Corsica, France. The facility serves a population of 2,700 and is situated near the Mediterranean coast, reflecting the region's focus on protecting its coastal environment. As an advanced treatment plant, Olmeto littoral goes beyond secondary treatment to remove nutrients and other pollutants, which is particularly important for sensitive coastal areas. The plant has a designed capacity of 7,500 cubic meters per day, with a current discharge volume of 481.68 cubic meters per day, indicating ample capacity for future growth. Under the EU Urban Waste Water Treatment Directive, plants in sensitive areas like Corsica are required to meet stringent nutrient removal standards. The treated effluent is discharged into the Mediterranean Sea, contributing to the protection of Corsica's pristine coastal waters and marine ecosystems. The island's watersheds are characterized by steep terrain and rapid runoff, making effective wastewater treatment essential to prevent eutrophication and safeguard biodiversity in the surrounding marine environment.

The plant discharges into the Mediterranean Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Corsica's coastal waters support diverse marine life, including seagrass meadows and fish nurseries. Advanced treatment helps reduce nitrogen and phosphorus loads, preventing algal blooms and preserving water quality for tourism and fisheries.
