Pramaggiore Blessaglia Wastewater Treatment Plant, Veneto, Italy

Pramaggiore Blessaglia is an advanced wastewater treatment plant located in Blessaglia, a locality within the municipality of Pramaggiore in the Veneto region of Italy. The plant serves a population of approximately 2,500 people and is designed to handle a capacity of 4,500 cubic meters per day, with a current discharge volume of about 495 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant operates under Italy's national implementation of the directive, which mandates advanced treatment for agglomerations discharging into sensitive water bodies. The treated effluent is discharged into local watercourses that eventually drain into the Adriatic Sea via the Venetian Lagoon system. The plant plays a key role in protecting the region's aquatic ecosystems, including the fragile lagoon environment, which supports diverse marine life and is an important migratory corridor for birds.

The plant discharges into the local drainage network that flows into the Venetian Lagoon, a coastal lagoon of the Adriatic Sea. This lagoon is a highly productive ecosystem supporting diverse aquatic life, including fish nurseries and migratory bird populations. The advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the lagoon and downstream coastal waters.
