COSTA_PARADISO_TRINITA_D_AGULTU is an advanced wastewater treatment plant located in the coastal town of Costa Paradiso, in the municipality of Trinità d'Agultu e Vignola, Sardinia, Italy. The plant serves a population of 5,000, typical of a small coastal agglomeration in the region. It is situated near the coast, reflecting the need to protect the marine environment of the Tyrrhenian Sea. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment is often implemented in sensitive areas to reduce nutrients and protect coastal waters. The designed capacity is 5,000 m³/day, and the current discharge volume is approximately 990 m³/day, indicating operational headroom. The treated effluent is discharged into the coastal waters of the Tyrrhenian Sea, part of the Mediterranean Sea. The area is known for its pristine beaches and marine ecosystems, including seagrass meadows and diverse marine life. The plant's advanced treatment helps minimize nutrient loading and protect the local marine environment, which is important for tourism and biodiversity.

The plant discharges into the Tyrrhenian Sea, a basin of the Mediterranean Sea. The coastal waters near Costa Paradiso support ecologically sensitive habitats, including Posidonia oceanica seagrass meadows, which are crucial for marine biodiversity and coastal protection. The advanced treatment reduces nutrient inputs, helping to prevent eutrophication and maintain water quality in this tourism-dependent region.
