San Demetrio Corone Gurisa Wastewater Treatment Plant, Calabria, Italy

San Demetrio Corone Gurisa is an advanced wastewater treatment plant located in San Demetrio Corone, a town in the province of Cosenza, Calabria, Italy. The plant serves a small population of 410 residents, reflecting its role in a rural or small-town setting. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The plant employs advanced treatment processes, going beyond the secondary treatment standard typically mandated for smaller communities. It has a designed capacity of 500 m³/day and currently discharges an average of 81.17 m³/day, indicating ample capacity for future growth. As an advanced facility, it likely incorporates nutrient removal or other tertiary processes to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Ionian Sea, part of the Mediterranean basin. The region's coastal and riverine ecosystems benefit from the plant's advanced treatment, which reduces nutrient loads and protects aquatic life. The plant's inland location, more than 10 km from the coast, further minimizes direct marine impact.

The plant discharges into local streams that flow toward the Ionian Sea, a key Mediterranean ecosystem supporting diverse marine life and fisheries. The advanced treatment helps protect downstream water quality in the Crati River basin and the Gulf of Taranto. Calabria's coastal waters are ecologically sensitive, hosting seagrass meadows and important nursery habitats for fish. By reducing nutrient and pollutant loads, the plant contributes to the health of these marine environments.
