IDL_MIGLIARINO Wastewater Treatment Plant, Migliarino Pisano, Vecchiano, Tuscany

IDL_MIGLIARINO is a former wastewater treatment plant located in Migliarino Pisano, a locality within the municipality of Vecchiano, in the province of Pisa, Tuscany, Italy. The plant served the local area and is now closed, reflecting changes in infrastructure or consolidation of treatment services in the region. As a secondary treatment facility, IDL_MIGLIARINO was designed to meet the standards of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries. With a designed capacity of 3,000 m³/day, it would have served a population equivalent of roughly 10,000 to 15,000 people, typical for a small agglomeration in the Italian regulatory framework. The plant's proximity to the coast (within 10 km) means its treated effluent would have discharged into a watercourse that flows into the Ligurian Sea, part of the Mediterranean Sea. The area is ecologically sensitive, supporting coastal ecosystems and marine biodiversity.

The plant is located near the coast of Tuscany, within the Arno River basin, which drains into the Ligurian Sea near Pisa. The coastal zone supports diverse marine life and is important for migratory birds. The receiving waters are part of a sensitive Mediterranean ecosystem where nutrient reduction is critical to prevent eutrophication.
