LA SASSA is a wastewater treatment plant located in the La Sassa area of Sonnino, in the Lazio region of Italy. The plant serves a population of approximately 3,500 people, classifying it as a small agglomeration under Italian and EU regulations. It is situated near the Tyrrhenian coast, within 10 km of the sea. 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 agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 3,500 m³/day and currently discharges an average of 692.88 m³/day, indicating significant spare capacity. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tyrrhenian Sea. The coastal location means the plant plays a crucial role in preventing nutrient pollution and protecting marine water quality. The Lazio coast supports diverse marine life and is important for tourism and fisheries, making advanced treatment essential for environmental protection.
Environmental context
The plant discharges into a local watercourse that flows to the Tyrrhenian Sea, part of the Mediterranean Sea basin. The coastal waters near Sonnino support seagrass meadows and diverse marine fauna, which are sensitive to nutrient enrichment. Advanced treatment helps minimize eutrophication risks and protects the ecological integrity of the coastal zone.
