Cavaso del Tomba Via Lerina Wastewater Treatment Plant, Caniezza, Veneto

Cavaso del Tomba Via Lerina is a secondary wastewater treatment plant located in Caniezza, a locality within the municipality of Cavaso del Tomba in the Veneto region of Italy. The plant serves a small population of 467 residents, reflecting its role in a rural or small-town setting. It is situated in the foothills of the Venetian Prealps, an area characterized by rolling hills and agricultural landscapes. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 500 cubic meters per day and an actual discharge volume of 92.45 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. As an Italian plant, it operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The treated effluent is discharged into local watercourses that ultimately drain into the Piave River basin. The Piave River flows southward through the Veneto region before entering the Adriatic Sea near Jesolo. The downstream environment supports diverse aquatic life and is important for regional agriculture and tourism. The plant's secondary treatment helps protect the Piave River and the Adriatic coastal ecosystem from nutrient pollution.

The plant discharges into local streams that feed into the Piave River, a major watercourse in northeastern Italy. The Piave River flows through the Veneto region and empties into the Adriatic Sea, supporting a diverse aquatic ecosystem including fish species such as trout and barbel. The river's delta and coastal area are ecologically sensitive, providing habitat for migratory birds and marine life. Secondary treatment reduces organic load and helps maintain water quality in this important watershed.
