IMPIANTO C DA VITELLACCIO Wastewater Treatment Plant, Cianciana, Sicily

IMPIANTO C DA VITELLACCIO is a municipal wastewater treatment plant located in Cianciana, a town in the province of Agrigento, Sicily, Italy. The plant serves a population of approximately 3,548 people, classifying it as a small agglomeration under Italian and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. The design capacity is 4,400 m³/day, and the actual discharge volume is 702.38 m³/day, indicating operational capacity well within design limits. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant's location in Sicily, a region with a Mediterranean climate, means that water resources are seasonally stressed, making effective wastewater treatment important for protecting downstream aquatic ecosystems and coastal water quality.

The plant discharges into the local drainage network that flows toward the southern coast of Sicily, eventually reaching the Mediterranean Sea. The receiving waters support diverse marine life and are part of a region where water scarcity and seasonal tourism place additional pressure on water resources. Effective secondary treatment helps reduce nutrient loads and organic pollution, protecting coastal ecosystems from eutrophication and maintaining water quality for recreational uses.
