Savoia di Lucania Cda Perolla Wastewater Treatment Plant, Basilicata

Savoia di Lucania Cda Perolla is a wastewater treatment plant located in the municipality of Savoia di Lucania, in the province of Potenza, Basilicata, Italy. The plant serves a small population of 220 residents, reflecting its role in a rural or small-town setting within the southern Italian region. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 500 m³/day indicates the plant's ability to handle peak flows, while the actual discharge volume of 43.55 m³/day suggests it operates well below capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea via rivers such as the Basento or Agri. The plant's operation helps protect downstream water quality and supports the ecological health of the region's aquatic environments.

The plant discharges into the local water network in the Basilicata region, which flows through the Basento or Agri river basins toward the Gulf of Taranto in the Ionian Sea. This area supports diverse aquatic life and is important for regional biodiversity, including fish species and migratory birds. The secondary treatment provided helps reduce organic pollutants and nutrients, mitigating eutrophication risks in the downstream coastal zone.
