VILLAMAR_LOC_CAMPU_GIOSSU Wastewater Treatment Plant, Villamar, Sardinia

VILLAMAR_LOC_CAMPU_GIOSSU is an advanced wastewater treatment plant located in the municipality of Villamar (Mara Arbarei) in the Medio Campidano province of Sardinia, Italy. The plant serves a population of approximately 2,960 residents and is part of the region's wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,620 m³/day and a current discharge volume of 585.98 m³/day, the plant operates well below its capacity. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The treated effluent is discharged into local water bodies that eventually drain into the Mediterranean Sea. Sardinia's inland waters support diverse aquatic ecosystems, and the plant's advanced treatment helps protect downstream environments from nutrient pollution and other contaminants.

The plant discharges into local streams that flow into the Mediterranean Sea, which is a semi-enclosed sea with limited water exchange. The surrounding watershed in Sardinia is characterized by Mediterranean climate and seasonal rainfall, making water quality management critical. Advanced treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in coastal waters, supporting marine biodiversity and fisheries.
