DEP_COM_VALLE_CUPA Wastewater Treatment Plant, Palombara Sabina, Lazio

DEP_COM_VALLE_CUPA is an advanced wastewater treatment plant located in Palombara Sabina, within the Metropolitan City of Rome, Lazio region, Italy. The plant serves a population of approximately 2,500 people, reflecting its role in managing domestic wastewater for this small agglomeration. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,200 m³/day and a current discharge volume of about 495 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Tiber River basin and then into the Tyrrhenian Sea. The plant's advanced treatment helps protect downstream water quality, supporting aquatic life and reducing nutrient loads in the sensitive Mediterranean coastal environment.

The plant discharges into the Tiber River basin, which flows through Lazio and empties into the Tyrrhenian Sea near Rome. This coastal area supports diverse marine ecosystems and is important for fisheries and tourism. The advanced treatment level helps minimize nutrient pollution, protecting the downstream aquatic environment from eutrophication and maintaining water quality for recreational use.
