IMPIANTO_CDA_PIZZUTA_C_DA_PILI Wastewater Treatment Plant, San Biagio Platani, Sicily

IMPIANTO_CDA_PIZZUTA_C_DA_PILI is a municipal wastewater treatment plant located in San Biagio Platani, a town in the province of Agrigento, Sicily, Italy. The plant serves a population of approximately 4,500 people, classifying it as a small agglomeration under Italian and EU regulations. It is situated inland, more than 10 km from the coast, and discharges treated wastewater into the local watershed. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,100 m³/day, the plant handles an average daily flow of about 890 m³, indicating significant reserve capacity. The treatment process likely involves biological oxidation and sedimentation, typical for secondary treatment facilities in this region. The treated effluent is discharged into the local drainage basin, which ultimately flows into the Mediterranean Sea via the Platani River or its tributaries. The plant plays a crucial role in protecting the water quality of the Platani River and the downstream coastal environment, supporting aquatic life and preventing eutrophication in the Mediterranean.

The plant discharges into the Platani River basin, which flows into the Mediterranean Sea along the southern coast of Sicily. This watershed supports diverse aquatic ecosystems and is important for local agriculture and tourism. The secondary treatment provided by the plant helps reduce organic pollutants and suspended solids, protecting the river's ecological health and the coastal waters from nutrient overload.
