IMPIANTO_PIANO_DI_MARGIO is a wastewater treatment plant located in Riesi, in the province of Caltanissetta, Sicily, Italy. The plant serves a population of approximately 13,458, placing it in the medium agglomeration category under Italian and EU regulations. As a plant of this scale in Italy, it is expected to comply with the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for inland discharges. The designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a facility sized for its community. The plant's treated effluent is discharged into local water bodies that eventually drain into the Mediterranean Sea via the Salso River or other coastal streams. This inland location reduces direct marine impact, but the receiving waters support local ecosystems and agricultural uses in the semi-arid Sicilian landscape.
Environmental context
The plant discharges into the drainage basin of the Salso River, which flows southward through Sicily and empties into the Mediterranean Sea near Licata. The watershed supports diverse aquatic life and is important for regional agriculture. The inland location buffers direct marine impact, but nutrient loading can affect downstream coastal waters.
