CIVITA_SCALO Wastewater Treatment Plant, La Grancia, Morino, Italy

CIVITA_SCALO is a wastewater treatment plant located in La Grancia, a locality within the municipality of Morino in the province of L'Aquila, Abruzzo, Italy. The plant serves a small population of 266 people, reflecting its role in a rural or peri-urban setting. It is situated inland, far from coastal areas, and operates under Italian and European regulatory frameworks. The plant provides primary treatment, which involves physical processes such as sedimentation to remove settleable solids. Primary treatment is the minimum level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent (PE) of less than 2,000. The plant's designed capacity of 450 m³/day aligns with the scale of the served population. The discharge volume is reported as 52.66 (likely in thousands of m³ per year), indicating a relatively low flow. The treated effluent is discharged into the local watershed, which ultimately drains into the Liri River basin and then to the Tyrrhenian Sea. The plant's operation helps protect the local water quality and downstream ecosystems, including the Liri River and its tributaries, which support diverse aquatic life and are important for regional agriculture and biodiversity.

The plant discharges into the Liri River basin, a major watercourse in central Italy that flows through Abruzzo and Lazio before reaching the Tyrrhenian Sea. The Liri River and its tributaries support diverse aquatic habitats and are used for irrigation and recreation. Downstream, the river passes through ecologically sensitive areas, including the Liri-Garigliano river system, which provides critical habitat for fish and bird species. The plant's primary treatment reduces suspended solids but does not remove nutrients, so the receiving water body may be subject to organic enrichment. However, the small population served limits the overall nutrient load.
