IMPIANTO C DA PIRRERA Wastewater Treatment Plant, Casteldaccia, Sicily

IMPIANTO C DA PIRRERA is a wastewater treatment plant located in Casteldaccia, a town in the province of Palermo, Sicily, Italy. The plant serves a population of 15,000 and is situated near the Tyrrhenian Sea coast, within 50 km of the shoreline. As an Italian wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size (10,000-150,000 population equivalent). The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating it is sized to handle the local wastewater load. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Tyrrhenian Sea. This coastal discharge requires careful management to protect marine water quality and the sensitive coastal ecosystems of Sicily, including seagrass meadows and marine habitats.

The plant discharges into the Tyrrhenian Sea, a basin of the Mediterranean Sea. The coastal waters near Casteldaccia support diverse marine life, including seagrass meadows and fish nurseries. The area is part of the larger Sicilian coastal ecosystem, which is ecologically sensitive due to tourism and fishing pressures. Proper treatment is essential to prevent nutrient pollution and protect bathing waters.
