Impianto C Da Maltempo Wastewater Treatment Plant, Giuliana, Sicily

Impianto C Da Maltempo is a municipal wastewater treatment plant located in Giuliana, a town in the province of Palermo, Sicily, Italy. The plant serves a population of about 4,000 people and has a designed capacity of 4,000 m³/day, indicating it is sized to match the local population. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. For a population of 4,000, secondary treatment meets the EU directive's requirements for inland discharges. The plant's discharge volume is approximately 792 m³/day, suggesting it operates below its designed capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. Sicily's inland waters support diverse aquatic life, and the plant's treatment helps protect downstream water quality. The region's Mediterranean climate, with dry summers and wet winters, influences flow patterns and treatment needs.

The plant discharges into a local watercourse that flows through the Sicilian interior and eventually reaches the Mediterranean Sea. The watershed supports agricultural and natural ecosystems, and the secondary treatment helps reduce nutrient and organic loads. The downstream environment includes coastal areas that are ecologically sensitive, supporting marine biodiversity and fisheries.
