CASTELFRANCO_SALVATRONDA Wastewater Treatment Plant, Castelfranco Veneto, Veneto, Italy

CASTELFRANCO_SALVATRONDA is a wastewater treatment plant located in Castelfranco Veneto, in the Veneto region of northeastern Italy. The plant serves a population of approximately 56,844, classifying it as a medium-to-large agglomeration under EU regulations. It is situated inland, away from the coast, and discharges into the local watershed. As an Italian plant serving over 50,000 people, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum. For agglomerations of this size, the directive also mandates more advanced treatment if the receiving waters are sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale of operation. The plant's treated effluent flows into the local river network, which eventually drains into the Adriatic Sea via the Po River basin. The Veneto region is characterized by intensive agriculture and urban development, making effective wastewater treatment crucial for protecting downstream water quality and aquatic ecosystems. The plant plays a key role in reducing nutrient loads and pollutants that could otherwise impact the sensitive lagoon environments of the northern Adriatic.

The plant discharges into the local river system, which is part of the Po River basin, one of Italy's largest and most ecologically significant watersheds. The Po River flows eastward into the Adriatic Sea, where nutrient pollution from upstream sources can contribute to eutrophication and harmful algal blooms. The Veneto region's dense population and agricultural activities place pressure on water quality, making the plant's treatment performance important for the health of downstream aquatic habitats and coastal ecosystems.
