DEP_PIAN_DEL_MUGNONE_FIESOLE_FIRENZE Wastewater Treatment Plant, Fiesole, Tuscany

DEP_PIAN_DEL_MUGNONE_FIESOLE_FIRENZE is a municipal wastewater treatment plant located in Pian di Mugnone, Fiesole, in the Tuscany region of Italy. The plant serves a population of approximately 2,500 and has a designed capacity of 6,400 cubic meters per day, with an average discharge volume of 499.27 cubic meters per day. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, a standard level for small to medium communities under EU regulations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The facility's capacity utilization is low, indicating ample reserve capacity for future growth or seasonal variations. Treated effluent from the plant is discharged into local watercourses that eventually flow into the Arno River, which drains into the Tyrrhenian Sea near Pisa. The Arno basin supports diverse aquatic life and is ecologically sensitive due to agricultural and urban runoff. The plant plays a key role in protecting downstream water quality in this historically and environmentally significant region.

The plant discharges into the Mugnone stream, a tributary of the Arno River. The Arno flows through Florence and Pisa before reaching the Tyrrhenian Sea. The watershed supports diverse aquatic ecosystems and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the coastal marine environment.
