Castelbaldo Via Nuova Wastewater Treatment Plant, Veneto, Italy

Castelbaldo Via Nuova is a former wastewater treatment plant located in Castelbaldo, a town in the Veneto region of northern Italy. The plant provided secondary treatment for municipal wastewater before its closure. As a facility in the Po River basin, it contributed to the region's water management infrastructure. The plant's operational status is closed, and no current treatment activities are ongoing. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Italian agglomerations of this scale are typically required to have secondary treatment, which this plant provided. The plant's closure may reflect upgrades or consolidation in the local wastewater network. The area drains into the Adige River, which flows into the Adriatic Sea. The plant's operation helped protect local water quality and downstream ecosystems in the Po Valley.

The plant is situated in the Po River basin, a major watershed in northern Italy that drains into the Adriatic Sea. The local watercourses support diverse aquatic life and are important for agriculture and biodiversity. The plant's secondary treatment would have reduced organic pollutants and suspended solids, protecting downstream water quality in the Adige River and ultimately the Adriatic Sea.
