DESULO_LOC_PERDALONGA Wastewater Treatment Plant, Desulo, Sardinia

DESULO_LOC_PERDALONGA is an advanced wastewater treatment plant located in the municipality of Desulo, in the province of Nuoro, Sardinia, Italy. The plant serves a population of approximately 3,734 residents, reflecting its role in managing domestic wastewater for this inland community in the mountainous Gennargentu region. As an advanced treatment facility, it goes beyond secondary biological processes to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 4,800 m³/day and currently discharges about 739 m³/day, indicating operational headroom. Under Italian and EU regulations, such plants must comply with the Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated effluent is discharged into local watercourses that drain into the Tirso River basin, eventually reaching the Mediterranean Sea. This advanced treatment helps protect the fragile ecosystems of Sardinia's interior and coastal waters, supporting biodiversity and water quality in the region.

The plant discharges into the Tirso River basin, which flows into the Mediterranean Sea. Sardinia's inland waters support diverse aquatic life, including endemic fish species. Advanced treatment reduces nutrient loading, protecting downstream ecosystems from eutrophication and safeguarding coastal water quality.
