IDL_VIA_VOLTA Wastewater Treatment Plant, Mastromarco, Toscana, Italy

IDL_VIA_VOLTA is an advanced wastewater treatment plant located in Mastromarco, a locality within the municipality of Lamporecchio in the province of Pistoia, Toscana, Italy. The plant serves a population of 3,741 and has a designed capacity of 4,200 m³/day, with a current discharge volume of 740.59 m³/day. It is situated inland, more than 50 km from the coast. 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 between 2,000 and 10,000 population equivalents, secondary treatment is generally mandated, but IDL_VIA_VOLTA's advanced level indicates a higher standard, possibly due to sensitive receiving waters or local regulations. The treated effluent is discharged into a local water body, likely a tributary of the Arno River basin, which flows through Toscana into the Tyrrhenian Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the region's waterways.

The plant discharges into a local watercourse within the Arno River basin, which drains into the Tyrrhenian Sea near Pisa. The Arno basin supports diverse aquatic life and is ecologically sensitive due to agricultural and urban pressures. Advanced treatment at IDL_VIA_VOLTA reduces nutrient loads, helping to prevent eutrophication in downstream waters and the coastal marine environment.
