Porto Corallo Villaputzu Wastewater Treatment Plant, Sardinia, Italy

Porto Corallo Villaputzu is an advanced wastewater treatment plant located in Villaputzu, in the Sardinia region of Italy. The facility serves a population of approximately 2,500, classifying it as a small agglomeration under Italian and EU regulations. Its coastal location places it within 10 kilometers of the Mediterranean Sea, making effective treatment essential for protecting marine ecosystems. 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 sensitive areas. With a designed capacity of 2,500 cubic meters per day and a discharge volume of about 495 cubic meters per day, the plant operates well within its capacity. This advanced level of treatment ensures high-quality effluent, reducing nutrient loads and other pollutants before discharge. The treated wastewater is discharged into the local environment near the coast, ultimately reaching the Mediterranean Sea. This area supports diverse marine life and is part of the broader Sardinian coastal ecosystem. By providing advanced treatment, the plant helps protect water quality in the region, supporting both ecological health and recreational uses of the coastal waters.

The plant discharges treated wastewater into the local coastal waters of Sardinia, which flow into the Mediterranean Sea. This region supports diverse marine habitats, including seagrass meadows and fish spawning grounds. Advanced treatment reduces nutrient pollution, helping to prevent eutrophication and protect the ecological balance of the coastal zone.
