Golfo Pevero Loc L'Unfarru Wastewater Treatment Plant, Porto Cervo, Sardinia

Golfo Pevero Loc L'Unfarru is an advanced wastewater treatment plant located in Porto Cervo, a coastal town in the Sardinia region of Italy. The plant serves a population of 4,178 and is situated in the Gallura Nord-Est Sardegna area, near the popular tourist destination of the Costa Smeralda. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,300 cubic meters per day and a current discharge volume of 827.10 cubic meters per day, the plant operates well within its capacity. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The treated effluent is discharged into the local coastal waters of the Tyrrhenian Sea, which is part of the Mediterranean Sea. The plant's location within 10 km of the coast means its discharge can affect nearby marine ecosystems, including seagrass meadows and coastal habitats that support diverse aquatic life. The region's tourism-driven economy relies on clean coastal waters, making the plant's advanced treatment crucial for environmental protection.

The plant discharges into the Tyrrhenian Sea, a basin of the Mediterranean Sea, which is a semi-enclosed sea with limited water exchange. The coastal waters near Porto Cervo support sensitive marine habitats, including Posidonia oceanica seagrass meadows, which are important for biodiversity and coastal protection. The advanced treatment helps minimize nutrient loading and protects these ecosystems from eutrophication.
