Overview
ROANA_FRAZ_MEZZASELVA is an advanced wastewater treatment plant in Mezzaselva, Veneto, Italy. It serves a population of 403 with a designed capacity of 500 m³/day and discharges 79.78 m³/day.
ROANA_FRAZ_MEZZASELVA is an advanced wastewater treatment plant located in the hamlet of Mezzaselva, part of the municipality of Roana in the Veneto region of Italy. The plant serves a small population of 403 residents and is situated in the Asiago Plateau, a mountainous area known for its alpine environment. As an advanced treatment facility, the plant provides a higher level of purification than secondary treatment, likely including nutrient removal to protect sensitive receiving waters. With a designed capacity of 500 m³/day and an actual discharge volume of 79.78 m³/day, the plant operates well below its capacity, indicating it can accommodate future growth. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are required to have appropriate treatment, and advanced treatment meets the highest standards. The plant's treated effluent is discharged into local watercourses that flow into the Brenta River, eventually reaching the Adriatic Sea. The surrounding watershed supports diverse aquatic life and is part of the Po Valley drainage basin. The advanced treatment helps protect downstream ecosystems, including the Brenta River's fish populations and the sensitive coastal environment of the northern Adriatic.
Environmental context
The plant discharges into small streams on the Asiago Plateau, which feed into the Brenta River. The Brenta flows south through the Veneto region and empties into the Adriatic Sea near Chioggia. The watershed supports trout and other cold-water species, and the advanced treatment ensures minimal nutrient loading, protecting downstream water quality and the ecologically important Venice Lagoon system.
