CDA_BADIA Wastewater Treatment Plant, Buseto Palizzolo, Sicily

CDA_BADIA is a wastewater treatment plant located in the Villaggio Badia area of Buseto Palizzolo, in the province of Trapani, Sicily, Italy. The plant serves a small agglomeration of approximately 1,766 residents, reflecting the rural character of this inland Sicilian community. 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. Its designed capacity is 1,800 cubic meters per day, and the reported discharge volume is 349.61 cubic meters per day, indicating operational headroom. The plant operates within Italy's national implementation of the directive, overseen by regional environmental authorities in Sicily. The treated effluent is discharged into the local watershed, which ultimately drains to the Tyrrhenian Sea. The plant's location within 10 km of the coast means its discharge can influence coastal water quality. Proper secondary treatment helps protect the marine environment and supports the ecological health of the Tyrrhenian Sea, which is important for tourism and fisheries in the region.

The plant discharges into the local drainage network that flows toward the Tyrrhenian Sea, a basin of the Mediterranean Sea. The coastal waters near Trapani support diverse marine life and are important for local fishing and tourism. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the nearshore environment and prevent eutrophication.
