IMPIANTO C DA PELLIZZERI Wastewater Treatment Plant, Gagliano Castelferrato, Sicily

IMPIANTO C DA PELLIZZERI is an advanced wastewater treatment plant located in Gagliano Castelferrato, a town in the province of Enna, Sicily, Italy. The plant serves a population equivalent of 3,391, placing it in the small agglomeration category under Italian and EU regulations. It is situated inland, more than 10 km from the coast, and operates within the Sicilian regional water management framework. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,000 m³/day and an actual discharge volume of 671.30 m³/day, the plant operates well below its capacity, indicating potential for future growth. The facility is part of Italy's national wastewater infrastructure, regulated under the Italian Legislative Decree 152/2006, which implements EU directives. The treated effluent is discharged into local water bodies that ultimately drain into the Ionian Sea via the Simeto River basin. The plant plays a key role in protecting the water quality of the surrounding watershed, which supports agricultural activities and local ecosystems. Its advanced treatment ensures high removal of pollutants, safeguarding downstream environments and contributing to the ecological health of the region.

The plant discharges into local streams that flow into the Simeto River, one of Sicily's major rivers, which empties into the Ionian Sea near Catania. The Simeto basin supports diverse aquatic life and is important for irrigation in the region. Advanced treatment at this facility helps reduce nutrient loading and protects the downstream marine environment from eutrophication.
