IDL_PAGNANA Wastewater Treatment Plant, Empoli, Toscana, Italy

IDL_PAGNANA is a wastewater treatment plant located in Empoli, in the Toscana region of Italy. The plant serves a population of approximately 69,411 people, placing it in the medium-to-large agglomeration category under EU classification. It is situated in the Arno River basin, an important waterway in central Italy. As a plant serving over 10,000 population equivalent, it is subject to 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 discharge enters sensitive areas. The regulatory framework ensures compliance with European standards. The plant's treated effluent is discharged into the local water system, ultimately reaching the Arno River and then the Tyrrhenian Sea. The Arno River flows through Florence and Pisa, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment at IDL_PAGNANA helps protect the ecological health of the Arno basin and the coastal marine environment.

IDL_PAGNANA discharges into the Arno River basin, which flows through Toscana and empties into the Tyrrhenian Sea near Pisa. The Arno River supports a variety of fish species and is an important migratory corridor for birds. The downstream environment includes coastal wetlands and marine habitats that benefit from controlled nutrient and pollutant loads. Effective wastewater treatment at this plant helps maintain water quality in the river and reduces the risk of eutrophication in the coastal zone.
