CASTELLUCCIO_INF_CARRICCHIO Wastewater Treatment Plant, Castelluccio Inferiore, Italy

CASTELLUCCIO_INF_CARRICCHIO is a municipal wastewater treatment plant located in Contrada Amoroso, Castelluccio Inferiore, in the province of Potenza, Basilicata, Italy. The plant serves a population of 3,600 and has a designed capacity of 10,000 m³/day, with an average discharge volume of 712.67 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards before discharge. The treated effluent is discharged into local water bodies that ultimately drain into the Ionian Sea via the Sinni River basin. The surrounding area is characterized by mountainous terrain and agricultural land, making the plant's role in protecting downstream water quality and aquatic ecosystems essential.

The plant discharges into the Sinni River basin, which flows into the Ionian Sea. This watershed supports diverse aquatic life and is used for irrigation and recreation. The secondary treatment helps reduce nutrient and organic loads, protecting the river's ecological health and the coastal marine environment from eutrophication.
