Aiello Calabro Macchia Sottana Wastewater Treatment Plant, Calabria

The Aiello Calabro Macchia Sottana wastewater treatment plant serves the small community of Aiello Calabro in the Calabria region of southern Italy. Located along Strada Provinciale 245, the plant is part of the municipal infrastructure for this inland town near the Tyrrhenian Sea coast. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations under 10,000 population equivalent. With a designed capacity of 1,000 cubic meters per day and a discharge volume of 168.27 cubic meters per day, it operates well below capacity, indicating room for future growth or seasonal fluctuations. The treated effluent is discharged into a local watercourse that flows toward the Tyrrhenian Sea, a key marine environment in the Mediterranean. The plant's advanced treatment helps protect coastal water quality and supports the ecological health of the downstream marine ecosystem, which is important for tourism and fisheries in Calabria.

The plant discharges into a small stream that drains into the Tyrrhenian Sea, a semi-enclosed basin of the Mediterranean Sea. The coastal waters near Aiello Calabro support diverse marine life and are important for local fishing and tourism. Advanced treatment reduces nutrient and pollutant loads, helping to prevent eutrophication and maintain water quality in this ecologically sensitive coastal zone.
