Scala Coeli Lavandaro Wastewater Treatment Plant, Calabria, Italy

The Scala Coeli Lavandaro wastewater treatment plant is located in the municipality of Scala Coeli, in the province of Cosenza, Calabria, Italy. It serves a population of approximately 1,746 residents, classifying it as a small agglomeration under Italian and EU regulations. The plant is situated near the Ionian Sea coast, within 10 km of the shoreline. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. Its designed capacity is 1,200 m³/day, with an actual discharge volume of 345.65 m³/day, indicating a utilization rate well below capacity. The plant operates under Italy's national implementation of the EU directive, which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local watercourses that flow into the Ionian Sea, part of the Mediterranean basin. The coastal waters in this region support diverse marine life, including seagrass meadows and fish nursery habitats. The plant's advanced treatment helps protect these sensitive coastal ecosystems from nutrient pollution and other contaminants.

The plant discharges into small streams that drain into the Ionian Sea, a semi-enclosed basin of the Mediterranean. The coastal zone near Scala Coeli features sandy beaches and rocky shores that support seagrass beds and diverse marine fauna. Advanced treatment reduces nutrient loads, protecting against eutrophication and preserving water quality for tourism and fisheries.
