IDL_FOSSA_MAESTRA is a wastewater treatment plant located in Marinella di Sarzana, a coastal area within the municipality of Sarzana in the Liguria region of Italy. The plant serves a population of approximately 42,790, placing it in the medium agglomeration category under Italian and EU regulations. As an Italian plant, IDL_FOSSA_MAESTRA operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a facility sized to handle the local population's wastewater load. The plant's treated effluent is discharged into the Ligurian Sea, a sensitive marine environment that supports diverse aquatic life and is an important recreational and economic resource for the region. The proximity to the coast means the plant must meet stringent discharge standards to protect water quality and marine ecosystems.
Environmental context
The plant discharges into the Ligurian Sea, part of the Mediterranean Sea basin. This coastal area supports diverse marine life, including seagrass meadows and fish populations, and is subject to EU regulations for sensitive areas. The plant's location within 50 km of the coast requires advanced treatment to minimize nutrient and pollutant loads that could cause eutrophication or harm marine habitats.
