DEP_COM_VIA_CASAL_FACENNA Wastewater Treatment Plant, Marcellina, Lazio

DEP_COM_VIA_CASAL_FACENNA is an advanced wastewater treatment plant located in Marcellina, a town in the Lazio region of Italy. The plant serves a population of approximately 3,000 residents, providing tertiary-level treatment to ensure high-quality effluent before discharge. Its designed capacity of 3,500 m³/day accommodates current and future local demand. As an advanced treatment facility, the plant likely incorporates processes such as nutrient removal or disinfection, meeting stringent Italian and EU standards. Italy implements the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and secondary treatment for all inland discharges. For a small agglomeration like Marcellina, advanced treatment exceeds the minimum requirements, indicating a commitment to environmental protection. The treated effluent is discharged into local watercourses that drain into the Tiber River basin, eventually reaching the Tyrrhenian Sea. The plant plays a crucial role in safeguarding the region's water quality, supporting downstream ecosystems and recreational uses. Its advanced treatment reduces nutrient loads and pollutants, protecting aquatic life and human health.

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 habitats and is used for irrigation and recreation. Advanced treatment at this plant helps minimize eutrophication risks and protects sensitive downstream environments, including coastal zones.
