Impianto Fraz Pagliara Tortorici - Primary Wastewater Treatment in Mercurio, Sicily

Impianto Fraz Pagliara Tortorici is a wastewater treatment plant located in the hamlet of Pagliara, near Mercurio, in the municipality of Tortorici, province of Messina, Sicily, Italy. The plant serves a small population of 320 residents, reflecting its role in a rural or peri-urban setting. Its designed capacity is 400 m³/day, with a current discharge volume of 63.35 m³/day. The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) of less than 2,000 are subject to less stringent requirements, and primary treatment is considered appropriate for this scale. The plant's operation is part of Italy's implementation of the directive, which aims to protect water quality across the region. The treated effluent is discharged into the local drainage network, which ultimately flows into the Tyrrhenian Sea via the coastal watershed of northern Sicily. Given the plant's proximity to the coast (within 10 km), the discharge has the potential to affect nearby marine ecosystems. The plant plays a key role in reducing organic pollution and protecting the coastal environment from untreated sewage.

The plant discharges into a small stream or drainage channel that flows toward the Tyrrhenian Sea near the northern coast of Sicily. This coastal area supports diverse marine life, including seagrass meadows and fish nurseries, which are sensitive to nutrient and pollutant inputs. The local watershed is characterized by steep terrain and seasonal rainfall, which can influence runoff and dilution capacity. Protecting this coastal zone is important for maintaining water quality and biodiversity in the Tyrrhenian Sea.
