Castelnovo Bariano Via D'Alighieri Wastewater Treatment Plant, Veneto, Italy

The Castelnovo Bariano Via D'Alighieri wastewater treatment plant is located in the municipality of Castelnovo Bariano, in the province of Rovigo, Veneto region, Italy. It serves a small population of 590 residents, reflecting its role in a rural or small-town setting within the Po River basin. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1000 m³/day and an actual discharge volume of 116.80 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately feed into the Po River, Italy's longest river, which flows into the Adriatic Sea. The plant's advanced treatment helps protect the sensitive Po Delta ecosystem and the Adriatic coastal waters from nutrient pollution and other contaminants.

The plant discharges into the Po River basin, which drains into the Adriatic Sea via the Po Delta. The Po Delta is a ecologically significant area that supports diverse aquatic life and migratory bird populations. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality and the fragile delta environment from eutrophication risks.
