Spilimbergo Nord Via del Macello Depuratore Cosa - Advanced Wastewater Treatment in Spilimbergo, Italy

The Spilimbergo Nord Via del Macello Depuratore Cosa is an advanced wastewater treatment facility located in Spilimbergo, within the Friuli-Venezia Giulia region of northeastern Italy. The plant serves a population of about 1,418, reflecting its role in managing municipal wastewater for a small community in the Pordenone area. As an advanced treatment plant, it goes beyond secondary biological processes to remove nutrients and other pollutants, ensuring high-quality effluent. The plant has a designed capacity of 3,000 m³/day and currently discharges an average volume of 280.71 m³/day, indicating operational headroom. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italy requires appropriate treatment for agglomerations of this size, and advanced treatment is typical in sensitive areas to protect water quality. The treated effluent is discharged into local watercourses that drain into the Tagliamento River, a major Alpine river known for its braided channels and high ecological value. The Tagliamento flows into the Adriatic Sea near the Gulf of Venice, supporting diverse aquatic habitats and migratory fish species. The plant's advanced treatment helps safeguard this sensitive downstream environment.

The plant discharges into the Tagliamento River basin, which flows through Friuli-Venezia Giulia into the northern Adriatic Sea. The Tagliamento is one of the last morphologically intact rivers in the Alps, supporting a rich diversity of riparian and aquatic life. Its gravel-bed dynamics create critical habitats for species such as the marble trout and various migratory birds. Advanced treatment at this plant reduces nutrient and pollutant loads, protecting the river's ecological integrity and the coastal waters of the Adriatic.
