Impianto C.da Rocca Grande Wastewater Treatment Plant, Caccamo, Sicily

Impianto C.da Rocca Grande is a municipal wastewater treatment plant located in Caccamo, within the province of Palermo in Sicily, Italy. The plant serves a small community of about 1,500 residents, reflecting its role in managing local domestic wastewater. Its location near the Tyrrhenian Sea places it in a coastal setting, which influences its discharge considerations. The plant provides secondary treatment, a standard level for small agglomerations under Italian and EU regulations. The EU Urban Waste Water Treatment Directive (91/271/EEC) requires secondary treatment for discharges to coastal waters from agglomerations of this size. The plant has a designed capacity of 1,500 cubic meters per day, and the reported discharge volume of approximately 297 cubic meters per day indicates operational activity within its capacity. The treated effluent is discharged into the local environment, likely affecting the nearby coastal waters of the Tyrrhenian Sea. As a coastal plant, its discharge must meet stringent standards to protect marine ecosystems. The surrounding area includes agricultural and natural landscapes, and the plant's operation supports water quality in the region.

The plant discharges treated wastewater into the Tyrrhenian Sea, a basin of the Mediterranean Sea. This coastal environment supports diverse marine life, including seagrass meadows and fish populations. The discharge must comply with Italian and EU standards to minimize nutrient loading and protect sensitive coastal habitats from eutrophication.
