DEP_COM_PONTE_STORTO Wastewater Treatment Plant, Castelnuovo di Porto, Lazio, Italy

DEP_COM_PONTE_STORTO is an advanced wastewater treatment plant located in Castelnuovo di Porto, a town in the Lazio region of Italy, within the Metropolitan City of Rome. The plant serves a population of approximately 2,700 residents, reflecting its role in managing domestic wastewater for a small community in the Tiber River basin. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 3,000 m³/day and currently discharges 534.50 m³/day, indicating it operates well below its capacity. This level of treatment aligns with Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Tiber River, which flows through Rome and into the Tyrrhenian Sea. The plant helps protect the Tiber basin and downstream coastal waters from nutrient pollution, supporting aquatic life and water quality in a region of ecological and cultural significance.

The plant discharges into the Tiber River basin, which flows through central Italy and empties into the Tyrrhenian Sea near Rome. The Tiber supports diverse aquatic ecosystems and is an important migratory corridor for fish. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in the downstream coastal zone, which is ecologically sensitive due to its proximity to the Mediterranean Sea.
