DEP_COM_POTANO Wastewater Treatment Plant, Cave, Lazio, Italy

DEP_COM_POTANO is a wastewater treatment facility located in Cave, a town in the Lazio region of Italy. The plant serves a population of around 2,500 people and is designed to handle up to 6,000 m³ of wastewater per day, indicating it operates below its full capacity. As an advanced treatment plant, it provides a high level of purification, which is essential for protecting the local environment. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. This level of treatment is typical for plants discharging into sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires advanced treatment for agglomerations of this size when discharging into sensitive catchments, ensuring compliance with stringent water quality standards. The treated effluent is discharged into local watercourses that eventually drain into the Tyrrhenian Sea. The plant plays a crucial role in safeguarding the water quality of the region's rivers and coastal areas. By providing advanced treatment, DEP_COM_POTANO helps maintain the ecological health of the downstream environment, supporting aquatic life and recreational uses.

The plant discharges into the local watershed, which is part of the Tiber River basin. The Tiber flows through Lazio and empties into the Tyrrhenian Sea near Rome. The downstream environment includes ecologically sensitive coastal areas that support diverse marine life and are important for tourism. Advanced treatment at this plant helps reduce nutrient loading, preventing eutrophication and protecting the coastal ecosystem.
