Borca di Cadore Villanova Wastewater Treatment Plant, Veneto, Italy

The Borca di Cadore Villanova wastewater treatment plant is located in Villanova, a frazione of Borca di Cadore in the province of Belluno, Veneto, Italy. The plant serves a population of approximately 2,564 residents, operating as a secondary treatment facility for this Alpine community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids, meeting the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 600 cubic meters per day and currently treats an average daily flow of 507.58 cubic meters, indicating operational headroom. The treated effluent is discharged into local watercourses that drain into the Piave River basin, ultimately reaching the Adriatic Sea. The plant plays a key role in protecting the sensitive Alpine watershed and downstream ecosystems, including the Piave River, which supports diverse aquatic life and is used for irrigation and recreation.

The plant discharges into the Piave River basin, which flows southeast through the Veneto region into the Adriatic Sea near Jesolo. The Piave River is an ecologically important watercourse supporting fish species such as marble trout and grayling, and its waters are used for agriculture and hydroelectric power. The plant's secondary treatment helps reduce nutrient loading and organic pollution, protecting downstream water quality in this sensitive Alpine-to-coastal transition zone.
