NULVI_LOC_BANZOS Wastewater Treatment Plant, Nulvi, Sardinia, Italy

NULVI_LOC_BANZOS is an advanced wastewater treatment plant located in Nulvi (Nujvi), in the province of Sassari, Sardinia, Italy. The plant serves a population of approximately 3,019 and has a designed capacity of 6,369 m³/day, with a current discharge volume of 597.66 m³/day. It operates under the Italian regulatory framework, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). As an advanced treatment facility, it provides a higher level of pollutant removal than secondary treatment, ensuring compliance with stringent effluent standards for sensitive areas. The plant's advanced treatment process likely includes nutrient removal (nitrogen and phosphorus) to protect the receiving environment. The plant is located inland, more than 10 km from the coast but within 50 km. The treated effluent is discharged into a local watercourse that eventually drains into the Mediterranean Sea, contributing to the protection of Sardinia's coastal and marine ecosystems. Environmental significance: The plant plays a key role in safeguarding the local watershed and downstream environments. By employing advanced treatment, it reduces nutrient loads that could otherwise cause eutrophication in coastal waters. Sardinia's Mediterranean climate and tourism-dependent economy rely on clean water resources, making the plant's performance critical for both ecological health and regional sustainability.

The plant discharges into a local watercourse that flows into the Mediterranean Sea, likely via the Gulf of Asinara or the Sardinian Sea. The region's watershed supports diverse aquatic life, including fish and migratory birds, and the coastal zone is ecologically sensitive due to seagrass meadows and marine biodiversity. Advanced treatment helps minimize nutrient pollution, protecting these habitats from eutrophication.
