CDA_ARENELLA is a wastewater treatment plant located in Pantelleria, an island municipality in the Sicilian region of Italy. The plant has a designed capacity of 3,500 cubic meters per day and provides primary treatment for the local community. As a primary treatment facility, CDA_ARENELLA performs basic physical processes such as sedimentation to remove suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this scale are generally required to meet secondary treatment standards, though primary treatment may be permitted in certain coastal areas with appropriate outfalls. The plant discharges into the marine environment of the Mediterranean Sea, which is ecologically sensitive. The surrounding waters support diverse marine life and are part of the broader Sicilian coastal ecosystem. Proper treatment is essential to protect water quality and marine habitats in this island setting.
Environmental context
CDA_ARENELLA discharges into the Mediterranean Sea near Pantelleria, an island in the Strait of Sicily. The coastal waters support seagrass meadows and diverse marine species, making nutrient and pollutant control critical. The plant's primary treatment level means that only basic solids removal occurs before discharge, which may impact local water quality if not managed with adequate dilution.
