Falcade Salpian Wastewater Treatment Plant, Caviola, Veneto

Falcade Salpian is a secondary wastewater treatment plant located in Caviola, a frazione of Falcade in the Veneto region of northern Italy. The facility serves a population of approximately 3,261 residents and is situated in the Dolomites, a mountainous area known for its tourism and environmental sensitivity. The plant is part of the municipal wastewater infrastructure managed by local authorities. As a secondary treatment plant, Falcade Salpian provides biological treatment to remove organic matter and suspended solids. The plant has a designed capacity of 2,550 cubic meters per day and currently treats an average daily flow of about 645.56 cubic meters, indicating ample reserve capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the minimum requirement for discharges into freshwater bodies, and this plant meets that standard. The treated effluent is discharged into local streams that feed into the Piave River, which flows southward to the Adriatic Sea. The Piave River basin supports diverse aquatic life and is an important water resource for the Veneto region. The plant's operation helps protect the river's water quality, particularly given the area's ecological significance as part of the Dolomites UNESCO World Heritage site (though not a designated protected area for water).

The plant discharges into tributaries of the Piave River, which flows through the Veneto region into the Adriatic Sea near Venice. The Piave basin supports diverse aquatic ecosystems, including fish species such as trout and grayling, and is a vital water source for agriculture and tourism. The Dolomites area is ecologically sensitive due to its alpine environment and seasonal tourist influx, making effective wastewater treatment crucial for preserving water quality.
