Fluminimaggiore Wastewater Treatment Plant | Sardinia, Italy

The Fluminimaggiore wastewater treatment plant is located in the town of Fluminimaggiore (Frùmini Majori), in the Sulcis Iglesiente area of Sardinia, Italy. It serves a population of approximately 3,506 residents and is situated near the southwestern coast of the island. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,500 m³/day and a discharge volume of 694.06 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into the local environment, ultimately reaching the Mediterranean Sea. As a coastal plant within 10 km of the coast, it plays a crucial role in protecting the marine ecosystem and the coastal waters of Sardinia, which support diverse aquatic life and are important for tourism and local fisheries.

The plant discharges into the coastal waters of southwestern Sardinia, which flow into the Mediterranean Sea. This area supports seagrass meadows and diverse marine species, making it ecologically sensitive. The advanced treatment helps minimize nutrient and pollutant loads, protecting the coastal environment and the regional marine ecosystem.
