Impianto C Da Canale Wastewater Treatment Plant, Acate, Sicily

Impianto C Da Canale is a municipal wastewater treatment plant located along SP90 in Acate, in the province of Ragusa, Sicily, Italy. The plant serves a population of approximately 8,000 people, placing it in the small-to-medium agglomeration category under Italian and EU regulations. The facility provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater or estuaries. The plant has a designed capacity of 7,000 m³/day, with a reported discharge volume of 0.01 million m³/year, indicating operational capacity utilization. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant's proximity to the coast (within 10 km) means its discharge can affect coastal water quality and marine ecosystems. Proper treatment is essential to protect the sensitive marine environment of the Sicilian coast.

The plant discharges into a watershed that flows to the Mediterranean Sea near the southern coast of Sicily. This coastal area supports diverse marine life and is important for local fisheries and tourism. The proximity to the coast increases the ecological sensitivity, as nutrient and pollutant loads can impact seagrass beds and coastal water quality. Effective secondary treatment helps mitigate eutrophication risks in the receiving marine environment.
