Prima Porta II Via Frassineto Wastewater Treatment Plant, Roma, Lazio

Prima Porta II Via Frassineto is an advanced wastewater treatment plant located in the Prima Porta district of Roma, in the Lazio region of Italy. The plant serves a population of approximately 3,000 residents, making it a small-scale facility within the broader wastewater infrastructure of the Rome metropolitan area. 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. With a designed capacity of 3,000 cubic meters per day and a discharge volume of 593.89 cubic meters, the facility operates well within its capacity. Italy's regulatory framework, under the directive, mandates appropriate treatment levels to protect sensitive water bodies. The treated effluent is discharged into inland waters, contributing to the health of local streams and rivers that eventually drain into the Tyrrhenian Sea. The plant plays a key role in safeguarding the Tiber River basin and the downstream coastal environment from nutrient pollution and other contaminants.

The plant discharges into inland waterways within the Tiber River basin, which flows through Rome and into the Tyrrhenian Sea. The Tiber is a major river supporting diverse aquatic life and providing water for agriculture and urban use. The advanced treatment helps reduce nutrient loads, protecting downstream ecosystems including coastal zones that are important for biodiversity and tourism.
