CALVELLO_ISCA_CASTALDO is a municipal wastewater treatment plant located in Calvello, in the Basilicata region of southern Italy. The plant serves a population of approximately 2,300 people, reflecting a small agglomeration in a rural inland setting. It is situated along Strada Provinciale 32bis, near the Camastra-Calvello road, within the province of Potenza. The plant provides secondary treatment, which is the standard level 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. The plant has a designed capacity of 4,000 m³/day, with a current discharge volume of 455.32 m³/day, indicating it operates well below its capacity. The treated effluent is discharged into local watercourses that eventually drain into the Ionian Sea via the Basento or Sinni river basins. The surrounding area is characterized by the Apennine mountains and agricultural land, making the protection of local streams important for both ecological health and downstream water quality.
Environmental context
The plant discharges into small streams in the Basilicata region, which flow into the Basento or Sinni rivers and ultimately reach the Gulf of Taranto in the Ionian Sea. The watershed supports diverse aquatic life and is important for local agriculture. The inland location reduces direct marine impact, but maintaining secondary treatment is essential to prevent nutrient enrichment in downstream waters.
