Impianto C da Billante Wastewater Treatment Plant, Sciacca, Sicily

Impianto C da Billante is a municipal wastewater treatment plant located in Contrada Foggia, Perriera, near Sciacca in the province of Agrigento, Sicily, Italy. The plant serves the local community and is designed with a capacity of 30,000 cubic meters per day, indicating it handles a significant volume of wastewater from 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 of this scale. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with European environmental standards before discharge. The treated effluent is discharged into the Mediterranean Sea, as the plant is located within 10 kilometers of the coast. This coastal discharge requires careful management to protect marine water quality and local ecosystems, including the nearby marine environment that supports diverse aquatic life and is important for tourism and fisheries in the region.

The plant discharges into the Mediterranean Sea near Sciacca, on the southern coast of Sicily.
