SAMUGHEO Wastewater Treatment Plant, Samugheo, Sardinia, Italy

SAMUGHEO is a wastewater treatment plant located in Samugheo, a town in the province of Oristano, Sardinia, Italy. The plant serves a population of about 4,014 residents, reflecting its role in managing municipal wastewater for this inland community. As part of Italy's wastewater infrastructure, it contributes to the sanitation and environmental protection of the region. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 7,573 cubic meters per day and an actual discharge volume of approximately 795 cubic meters per day, it operates well below its capacity, indicating robust treatment capability. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, and SAMUGHEO exceeds this standard with advanced treatment. The treated effluent is discharged into local inland waters, eventually draining into the Tirso River basin and then into the Mediterranean Sea. This discharge supports the ecological health of the surrounding watershed, which is important for Sardinia's diverse aquatic life and agricultural activities. The plant's advanced treatment helps protect downstream water quality and the sensitive coastal environment of the Mediterranean.

SAMUGHEO discharges treated wastewater into local streams that flow into the Tirso River, Sardinia's longest river, which empties into the Gulf of Oristano on the Mediterranean Sea. The watershed supports diverse aquatic ecosystems and is important for regional agriculture and tourism. Advanced treatment at the plant helps minimize nutrient and pollutant loads, protecting downstream habitats and the coastal marine environment from eutrophication and contamination.
