Cirigliano Vallepiano is a municipal wastewater treatment plant located in Cirigliano, a small town in the Basilicata region of southern Italy. The plant serves a population of approximately 450 residents, reflecting the rural and small-scale character of the area. 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 with a population equivalent (PE) between 2,000 and 10,000. Although the plant's designed capacity is 1,000 m³/day, the actual discharge volume is 89.08 m³/day, indicating that the plant operates well below its capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea via the Basento River or nearby coastal streams. The plant plays a key role in protecting the region's water quality, supporting both local ecosystems and downstream aquatic life.
Environmental context
The plant discharges into a small watercourse within the Basento River basin, which flows eastward into the Gulf of Taranto in the Ionian Sea. The surrounding area is characterized by agricultural land and natural vegetation, and the receiving waters support diverse aquatic life. The plant's secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream coastal waters.
