IDL_Tavarnuzze_Via_Cassia_160A Wastewater Treatment Plant, Impruneta, Tuscany

IDL_Tavarnuzze_Via_Cassia_160A is a wastewater treatment plant located in the Tavarnuzze area of Impruneta, within the metropolitan city of Florence, Tuscany, Italy. The plant serves a population of approximately 4,794 and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 949.04 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations between 2,000 and 10,000 population equivalents discharging into freshwater or estuaries. This directive ensures that wastewater is treated to remove organic matter and suspended solids before release. The treated effluent is discharged into the local water system, which ultimately drains into the Arno River basin. The Arno River flows through Florence and Pisa before reaching the Tyrrhenian Sea. The plant plays a role in protecting the Arno's water quality and the downstream ecosystems, including the coastal marine environment.

The plant discharges into the Arno River basin, which flows through Tuscany to the Tyrrhenian Sea. The Arno is a major river supporting diverse aquatic life and providing water for agriculture and urban use. Downstream, the river passes through Florence and Pisa, where water quality is critical for ecological health and tourism. The plant's secondary treatment helps reduce organic pollution, but nutrient removal may be limited, which could affect eutrophication in sensitive coastal areas.
