Impianto Consortile di Misterbianco - Secondary Wastewater Treatment Plant in Misterbianco, Sicily

Impianto Consortile di Misterbianco is a municipal wastewater treatment plant located in Misterbianco, a town in the Metropolitan City of Catania, Sicily, Italy. The plant serves the urban area of Misterbianco and surrounding communities, operating as a key component of the region's sanitation infrastructure. Its location near the eastern coast of Sicily places it within the sensitive coastal zone of the Ionian Sea. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. With a designed capacity of 47,500 m³/day, it is classified as a large agglomeration under the directive, which mandates secondary treatment as a minimum and tertiary treatment if discharging into sensitive areas. The plant's capacity suggests it serves a population equivalent well above 10,000, consistent with the population of Misterbianco and adjacent areas. Treated effluent from the plant is discharged into the local water system, ultimately reaching the Ionian Sea. The receiving environment supports diverse marine life and is an important ecological zone for the Mediterranean. The plant's operation helps protect coastal water quality and supports the health of downstream ecosystems, including nearby beaches and marine habitats.

The plant discharges into the Ionian Sea via local watercourses, contributing to the coastal watershed of eastern Sicily. The Ionian Sea in this region supports diverse marine ecosystems, including seagrass meadows and fish nurseries, and is a vital resource for tourism and fisheries. The plant's secondary treatment helps reduce nutrient and pollutant loads, mitigating eutrophication risks in the coastal zone.
