ARCOLE_LOC_GAZZOLO Wastewater Treatment Plant, Gazzolo, Veneto, Italy

ARCOLE_LOC_GAZZOLO is an advanced wastewater treatment plant located in Gazzolo, a locality within the municipality of Arcole, in the Veneto region of northern Italy. The plant serves a small population of 1,008 and has a designed capacity of 1,500 units, with a current discharge volume of 199.55 units, indicating it operates well below its capacity. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), such advanced treatment is typically required for discharges into sensitive areas, though for agglomerations under 10,000 population equivalent, secondary treatment is the baseline. The plant's advanced level suggests it meets stringent local or regional standards for water quality protection. The treated effluent is discharged into the local water system, which ultimately drains into the Adige River basin. The Adige River flows through the Veneto region and empties into the Adriatic Sea near Chioggia. This water body supports diverse aquatic life and is important for irrigation and recreation in the Po Valley. The plant's advanced treatment helps protect downstream ecosystems from nutrient pollution and other contaminants.

The plant discharges into the local water network that feeds into the Adige River basin, one of Italy's major rivers. The Adige flows through the Veneto plain and into the Adriatic Sea, supporting a rich aquatic ecosystem including fish species like trout and barbel. The surrounding area is agricultural, so the plant's advanced treatment helps prevent nutrient runoff that could cause eutrophication in the Adriatic coastal zone.
