IDL_RIALTO Wastewater Treatment Plant, Monte San Savino, Tuscany

IDL_RIALTO is an advanced wastewater treatment plant located in Monte San Savino, in the Tuscany region of Italy. The plant serves a population of approximately 4,250 people and is situated along the Strada provinciale dell'Esse, within the province of Arezzo. As a municipal facility, it plays a key role in managing wastewater for this inland community. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Its designed capacity is 4,500 m³/day, with a reported discharge volume of 841.55 m³/day, indicating it operates well below its maximum capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, and IDL_RIALTO exceeds this standard with its advanced treatment level. The treated effluent is discharged into local watercourses that drain into the Arno River basin, ultimately reaching the Tyrrhenian Sea. The plant's advanced treatment helps protect downstream water quality and supports the ecological health of the region's rivers and coastal waters.

The plant discharges into the local drainage network that feeds into the Arno River basin, which flows through Tuscany to the Tyrrhenian Sea. The Arno River supports diverse aquatic life and is an important water resource for the region. Advanced treatment at IDL_RIALTO reduces nutrient loading, helping to prevent eutrophication in downstream waters and protecting the ecological balance of the river and coastal environment.
