Impianto Frazione Pedalino - Secondary Wastewater Treatment Plant in Comiso, Sicily

Impianto Frazione Pedalino is a municipal wastewater treatment plant located in the Pedalino district of Comiso, in the province of Ragusa, Sicily, Italy. The plant serves a population of approximately 3,000 residents, classifying it as a small agglomeration under Italian and EU regulations. It is situated inland, more than 10 km from the coast, and operates under Italy's implementation of the EU Urban Waste Water Treatment Directive. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive for inland freshwater discharges from agglomerations of this size. With a designed capacity of 3,000 m³/day and an actual discharge volume of 593.89 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that drain into the Mediterranean Sea via the Ionian Sea. The region's watershed supports diverse aquatic life and agricultural activities. Proper treatment is essential to protect downstream ecosystems and maintain water quality for irrigation and recreational use in the surrounding area.

The plant discharges into local streams that flow into the Ionian Sea, part of the Mediterranean basin. The watershed supports agricultural irrigation and sensitive coastal ecosystems. Effective secondary treatment reduces nutrient loads, helping to prevent eutrophication in downstream marine environments and protecting biodiversity in the region's rivers and coastal waters.
