CAORLE_PALANGON Wastewater Treatment Plant, Caorle, Veneto, Italy

CAORLE_PALANGON is a wastewater treatment plant located in Caorle, a coastal town in the Veneto region of northeastern Italy. The plant serves a population of approximately 70,052, placing it in the medium-to-large agglomeration category under Italian and EU regulations. Its location near the Adriatic Sea makes its discharge quality critical for coastal water quality. As a plant of this scale in Italy, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The Adriatic coast, particularly the northern Adriatic, includes sensitive zones such as the Lagoon of Venice, where nutrient removal is often mandated to prevent eutrophication. The plant's designed capacity is 1. 00 (likely in thousands of cubic meters per day), indicating a facility sized for its population. The plant's discharge ultimately reaches the Adriatic Sea, a semi-enclosed basin with limited water exchange, making it vulnerable to nutrient pollution. The Veneto region's coastal waters support tourism, fisheries, and diverse marine life. Effective treatment at CAORLE_PALANGON helps protect bathing waters and the ecological health of the northern Adriatic, which is influenced by freshwater inputs from the Po River and smaller coastal streams.

The plant's treated effluent discharges into the Adriatic Sea, a semi-enclosed basin that is ecologically sensitive due to limited water exchange and high nutrient loads from surrounding agricultural and urban areas. The northern Adriatic supports seagrass meadows, fish nurseries, and migratory bird habitats. Protecting this coastal environment requires advanced treatment to reduce nitrogen and phosphorus, preventing algal blooms and hypoxia.
