DOLIANOVA_LOC_BARDELLA_ZONA_PIP Wastewater Treatment Plant, Dolianova, Sardinia

DOLIANOVA_LOC_BARDELLA_ZONA_PIP is an advanced wastewater treatment plant located in Dolianova, in the Sardinia region of Italy. The plant serves a population of approximately 3,746 residents, making it a small-scale facility within the local municipal infrastructure. It is situated inland, more than 10 kilometers from the coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant's designed capacity is 3,746 population equivalents, and it discharges an average of 741.58 cubic meters of treated wastewater per day. The treated effluent is discharged into local watercourses that drain toward the southern coast of Sardinia. The receiving water body ultimately flows into the Tyrrhenian Sea, part of the Mediterranean Sea. The advanced treatment level helps safeguard the ecological health of these waters, which support diverse aquatic life and are important for regional biodiversity.

The plant discharges into local streams that flow toward the southern Sardinian coast, eventually reaching the Tyrrhenian Sea. The surrounding watershed includes agricultural and natural areas, and the advanced treatment level helps protect downstream ecosystems from nutrient pollution. The region's Mediterranean climate and coastal proximity make water quality management critical for preserving marine habitats and supporting tourism and fisheries.
