Environmental context

The plant discharges into inland watercourses that flow through the Sicilian interior, eventually reaching the Mediterranean Sea. The local watershed supports diverse aquatic life and is part of a semi-arid Mediterranean climate, where water resources are seasonally scarce. Proper treatment helps prevent nutrient enrichment and pathogen contamination in downstream rivers and coastal zones, which are ecologically sensitive areas for marine biodiversity.
