SEDICO_MASTELLA_MAS Wastewater Treatment Plant, Ponte Mas, Veneto

SEDICO_MASTELLA_MAS is an advanced wastewater treatment plant located in Ponte Mas, a locality in the municipality of Sospirolo, Belluno province, Veneto, Italy. The plant serves a population of 2,274, reflecting its role in managing domestic wastewater for this small Alpine community. The plant provides advanced treatment, which goes beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 2,000 m³/day and an average discharge volume of 450.17 m³/day, the facility operates well within its capacity. As an Italian plant, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for sensitive areas and agglomerations of this size. The treated effluent is discharged into local watercourses that ultimately drain into the Piave River basin, flowing south toward the Adriatic Sea. The plant's advanced treatment helps protect the sensitive Alpine ecosystem and downstream water quality in the Veneto region.

The plant discharges into the Piave River basin, which flows through the Dolomites and the Veneto plain before reaching the Adriatic Sea near Venice. The watershed supports diverse aquatic life, including fish species like the marble trout, and is ecologically sensitive due to its Alpine origin and downstream lagoon environments. Advanced treatment helps minimize nutrient loading and protects this fragile ecosystem.
