IMPIANTO C DA POZZILLO ROSSELLI Wastewater Treatment Plant, Altavilla Milicia, Sicily

IMPIANTO C DA POZZILLO ROSSELLI is a municipal wastewater treatment plant located in Altavilla Milicia, a town in the Province of Palermo, Sicily, Italy. The plant serves a population of approximately 5,000 residents and has a designed capacity of 6,000 m³/day, with an average daily discharge of 989.82 m³/day. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids before discharge. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (5,000 population equivalent) are required to provide secondary treatment, which this plant meets. The plant's operation is subject to Italian national regulations implementing the directive, ensuring compliance with effluent standards. The treated wastewater is discharged into the coastal waters of the Tyrrhenian Sea, given the plant's proximity to the coast (within 10 km). This discharge contributes to the local marine environment, which supports diverse aquatic life and is part of the broader Mediterranean Sea ecosystem. The plant plays a key role in protecting coastal water quality and public health in the Altavilla Milicia area.

The plant discharges treated effluent into the Tyrrhenian Sea, a basin of the Mediterranean Sea. The coastal waters near Altavilla Milicia support diverse marine habitats, including seagrass meadows and rocky reefs, which are sensitive to nutrient loading and pollution. Effective secondary treatment helps mitigate eutrophication risks and protects the ecological integrity of this coastal zone.
