OPPIDO_CPOZZELLA Wastewater Treatment Plant, Oppido Lucano, Basilicata

OPPIDO_CPOZZELLA is a wastewater treatment plant located in Oppido Lucano, a town in the province of Potenza, Basilicata, Italy. The plant serves a population of approximately 3,500 residents, providing secondary treatment to municipal wastewater. Its designed capacity is 4,000 cubic meters per day, with an average discharge volume of about 693 m³/day. As a secondary treatment facility, the plant meets the standard requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000, which aligns with the plant's scale. The plant's operational context is shaped by Italian national regulations implementing EU directives, ensuring compliance with effluent quality standards. The treated effluent is discharged into local water bodies within the Basilicata region, which ultimately drain into the Ionian Sea via rivers such as the Bradano. The plant plays a key role in protecting the region's water resources and supporting the ecological health of downstream environments, including agricultural areas and sensitive aquatic habitats.

The plant discharges into the local watershed of the Bradano River basin, which flows through Basilicata and empties into the Gulf of Taranto in the Ionian Sea. This coastal area supports diverse marine life and is important for local fisheries. The secondary treatment provided by the plant helps reduce nutrient and organic loads, mitigating eutrophication risks in the downstream coastal zone.
