IDL_TORRICCHIO Wastewater Treatment Plant, Santa Lucia, Toscana, Italy

IDL_TORRICCHIO is a wastewater treatment plant located in the Torricchio area of Santa Lucia, a frazione of Uzzano in the province of Pistoia, Toscana, Italy. The plant serves a population of approximately 3,800 people and has a designed capacity of 3,500 cubic meters per day, with an average discharge volume of 752.86 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As an Italian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. For plants serving fewer than 10,000 people, secondary treatment is typically sufficient, but the advanced level here indicates a higher standard, possibly due to sensitive receiving waters. The treated effluent is discharged into local watercourses that ultimately drain into the Arno River basin and then into the Tyrrhenian Sea. The plant plays a key role in protecting the local environment, including the downstream ecosystems of the Arno River and the coastal waters of the Ligurian Sea.

The plant discharges into the local drainage network that feeds into the Arno River, one of Italy's major rivers, which flows through Tuscany and empties into the Tyrrhenian Sea near Pisa. The Arno basin supports diverse aquatic life and is ecologically sensitive due to agricultural runoff and urban pressures. The advanced treatment at IDL_TORRICCHIO helps reduce nutrient loading, protecting downstream water quality and the marine environment.
