SARDARA_LOC_ROIA_SA_LATIA Wastewater Treatment Plant, Sàrdara, Sardegna

SARDARA_LOC_ROIA_SA_LATIA is an advanced wastewater treatment plant located in the municipality of Sàrdara/Sardara, in the Medio Campidano province of Sardegna, Italy. The plant serves a population of approximately 4,603 people, reflecting its role in managing domestic wastewater for this inland community. Its designed capacity of 5,400 m³/day indicates a facility sized to accommodate local flows with some reserve capacity. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving environments. As part of Italy's implementation of the directive, plants in sensitive areas must meet stricter effluent standards, and this facility's advanced level suggests it operates under such requirements. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. Sardegna's rivers and streams are often seasonal, and the island's water resources are critical for agriculture and ecosystems. The plant's advanced treatment helps safeguard downstream water quality, supporting both human uses and the ecological health of the region's coastal and marine environments.

The plant discharges into the local drainage basin of Sardegna, an island in the Mediterranean Sea. The receiving water body is likely a small river or stream that flows into the Mediterranean, which is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. Advanced treatment at this plant reduces nitrogen and phosphorus loads, helping to prevent eutrophication in coastal waters and protect marine biodiversity, including seagrass meadows and fish habitats.
