LONGARONE_PROVAGNA Wastewater Treatment Plant, Longarone, Veneto, Italy

LONGARONE_PROVAGNA is an advanced wastewater treatment plant located in the Faè district of Longarone, in the Veneto region of northern Italy. The plant serves a small population of 341 residents, reflecting its role in a rural or small-town setting within the Belluno province. The plant employs advanced treatment processes, which go beyond the secondary treatment standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 440 m³/day and an actual discharge volume of 67.51 m³/day, the facility operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Piave River, a major watercourse in the Veneto region. The Piave River flows into the Adriatic Sea, supporting diverse aquatic life and providing water for irrigation and recreation. The advanced treatment helps protect the sensitive downstream environment, including the Piave River ecosystem and the Adriatic coastal zone.

The plant discharges into the Piave River basin, which flows southeast through the Veneto region and empties into the Adriatic Sea near Jesolo. The Piave River supports a variety of fish species and is an important migratory corridor for birds. The advanced treatment level ensures that nutrient and pollutant loads are minimized, protecting the river's ecological health and the coastal waters of the northern Adriatic, which are subject to eutrophication risks from agricultural and urban runoff.
