DEP_COM_ARCI Wastewater Treatment Plant, Tivoli, Lazio, Italy

DEP_COM_ARCI is an advanced wastewater treatment plant located in Tivoli, within the Metropolitan City of Rome, Lazio, Italy. The plant serves a small community of approximately 2,000 residents, reflecting its role in managing local domestic wastewater in a suburban setting. The plant operates with advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 2,000 m³/day, and it currently discharges about 395.93 m³/day of treated effluent. As an Italian facility, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for sensitive areas and agglomerations of this size. The treated effluent is discharged into local water bodies that ultimately drain into the Tiber River basin, which flows through Rome and into the Tyrrhenian Sea. The plant's advanced treatment helps protect the downstream aquatic environment, including the Tiber River and the coastal waters of the Tyrrhenian Sea, from nutrient pollution and other contaminants.

The plant discharges into the Tiber River basin, which flows through Rome and empties into the Tyrrhenian Sea. The Tiber River supports diverse aquatic life and is an important ecological corridor in central Italy. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and the sensitive coastal ecosystem of the Tyrrhenian Sea.
