IDL_BAGNO_DI_GAVORRANO Wastewater Treatment Plant, Bagno di Gavorrano, Tuscany

IDL_BAGNO_DI_GAVORRANO is a municipal wastewater treatment plant located in Bagno di Gavorrano, a frazione of Gavorrano in the province of Grosseto, Tuscany, Italy. The plant serves a population of approximately 4,430, placing it in the small agglomeration category under Italian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 5,000 cubic meters per day and an average daily discharge volume of about 877 cubic meters, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tyrrhenian Sea. The plant's coastal proximity (within 10 km of the coast) means its discharge contributes to the nutrient load in the coastal marine environment, an area that supports diverse marine life and is subject to EU directives on water quality and marine protection.

The plant discharges into a watercourse that flows through the Maremma region of Tuscany and eventually reaches the Tyrrhenian Sea. The coastal waters near Bagno di Gavorrano are part of a sensitive marine ecosystem that supports seagrass meadows and fish nurseries. Nutrient inputs from treated wastewater can influence local water quality, making effective secondary treatment and monitoring important for preserving the ecological balance of this coastal area.
