IDL_CINTOLESE Wastewater Treatment Plant, Monsummano Terme, Tuscany

IDL_CINTOLESE is an advanced wastewater treatment plant located in Cintolese, a locality of Monsummano Terme in the province of Pistoia, Tuscany, Italy. The plant serves a population of approximately 2,588 residents and has a designed capacity of 5,000 cubic meters per day, indicating it operates well below its maximum capacity. As an advanced treatment facility, IDL_CINTOLESE goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Tyrrhenian Sea via the Arno River basin. The plant plays a key role in protecting the water quality of the surrounding region, which includes agricultural areas and the natural springs of Monsummano Terme, known for their thermal waters.

The plant discharges into the local drainage network that feeds into the Nievole River, a tributary of the Arno River. The Arno flows through Florence and Pisa before reaching the Tyrrhenian Sea. This watershed supports diverse aquatic life and is ecologically sensitive due to agricultural runoff and urban pressures. The advanced treatment at IDL_CINTOLESE helps reduce nutrient loading, protecting downstream habitats and the coastal marine environment.
