TIRIOLO_SOLURI Wastewater Treatment Plant, Soluri, Calabria, Italy

TIRIOLO_SOLURI is an advanced wastewater treatment plant located in Soluri, a locality within the municipality of Tiriolo in the Calabria region of southern Italy. The plant serves a small population of 250 residents, reflecting its role in a rural or peri-urban setting. Its location in the Calabrian Apennines influences the local hydrology and treatment requirements. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 250 cubic meters per day and an actual discharge volume of 49.49 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all discharges. The treated effluent is discharged into local watercourses that drain toward the Ionian Sea. The receiving water body is part of the broader catchment of the Catanzaro province, which supports agricultural activities and local ecosystems. The advanced treatment level helps protect downstream water quality and aquatic life in this Mediterranean region.

The plant discharges into small streams that flow through the Calabrian hills toward the Ionian Sea, a semi-enclosed basin with limited water exchange. The region's steep terrain and seasonal rainfall patterns can lead to rapid runoff, making advanced treatment important for preventing nutrient enrichment and protecting coastal water quality. The downstream environment supports diverse aquatic habitats and is used for irrigation and recreation.
