DEP_MADONNA_DELLA_TOSSE Wastewater Treatment Plant, Castelnuovo di Garfagnana, Tuscany

DEP_MADONNA_DELLA_TOSSE is a secondary wastewater treatment plant located in Castelnuovo di Garfagnana, a town in the Garfagnana region of Tuscany, Italy. The plant serves a small population of 58 people and has a designed capacity of 100 m³/day, with a current discharge volume of 11.48 m³/day. It is situated inland, more than 10 km from the coast. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are typically required to have appropriate treatment, and secondary treatment meets the standard for discharges into freshwater bodies. The plant's operational context aligns with Italian national regulations implementing the directive. The treated effluent is discharged into the local watershed, which drains into the Serchio River and eventually reaches the Tyrrhenian Sea. The Serchio River supports diverse aquatic life and is an important water resource for the region. The plant's secondary treatment helps protect the river's water quality and downstream ecosystems.

The plant discharges into the Serchio River basin, which flows through the Garfagnana valley and into the Tyrrhenian Sea near Viareggio. The Serchio River supports a variety of fish species and is used for irrigation and recreation. Secondary treatment ensures that the effluent meets standards to protect the river's ecological health and downstream coastal waters.
