FLUSSIO Wastewater Treatment Plant, Flussio, Sardinia, Italy

FLUSSIO wastewater treatment plant is located in Flussio, a small town in the province of Oristano, Sardinia, Italy. The facility served a population of approximately 458 people and was designed with a capacity of 2,200 cubic meters per day. The plant is now closed and no longer operational. The plant provided advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like Flussio (under 2,000 population equivalent) are typically required to provide appropriate treatment, and advanced treatment is often implemented in sensitive areas to protect water quality. The plant is located within 10 km of the coast, indicating its discharge likely affected coastal waters. Sardinia's coastal environment supports diverse marine life and is important for tourism and fisheries. The closure of the plant suggests that wastewater management in the area has been restructured, possibly with flows redirected to a larger regional facility to improve efficiency and environmental protection.

The plant is situated near the coast of Sardinia, within 10 km of the Mediterranean Sea. Its discharge would have entered coastal waters, which are part of the broader Mediterranean ecosystem. This region supports seagrass meadows, coral habitats, and migratory fish species. The closure of the plant may reduce local nutrient loading, benefiting nearshore water quality and marine biodiversity.
