IMPIANTO C DA MURLACCHIELLO S PAOLINO Wastewater Treatment Plant, Sutera, Sicily

IMPIANTO C DA MURLACCHIELLO S PAOLINO is a wastewater treatment plant located in Sutera, a town in the province of Caltanissetta, Sicily, Italy. The plant serves a small population of 250 people, reflecting its role in a rural or small community setting. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. The plant provides secondary treatment, which is the standard biological treatment required for small agglomerations under EU regulations. With a designed capacity of 250 m³/day and a discharge volume of 49.49 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. Sicily's water bodies support diverse aquatic life and are important for regional biodiversity. The plant's inland location, more than 10 km from the coast, reduces direct marine impact, but its discharge still contributes to the overall health of the island's river systems and coastal waters.

The plant discharges into the local watershed in Sicily, which drains into the Mediterranean Sea. The region's water bodies support diverse aquatic ecosystems, including fish and invertebrate species. As an inland plant, its effluent influences the quality of streams and rivers that eventually reach the coast, affecting both freshwater and marine environments. Proper treatment is essential to protect these habitats from nutrient pollution and other contaminants.
