Overview
STAGNONI wastewater treatment plant serves La Spezia, Liguria, Italy, with a population equivalent of 94,634. The facility is located near the coast and operates under EU Urban Waste Water Treatment Directive standards.
STAGNONI is a wastewater treatment plant located in La Spezia, in the Liguria region of northwestern Italy. The facility serves a population equivalent of approximately 94,634, placing it in the medium-to-large agglomeration category under EU classification. Its location near the Ligurian Sea influences its operational and environmental context. As a plant of this scale in Italy, STAGNONI is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum, and potentially tertiary treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar units), indicating a substantial infrastructure investment. Regulatory compliance ensures appropriate treatment levels. The treated effluent from STAGNONI ultimately discharges into the Ligurian Sea, a part of the Mediterranean Sea. This coastal environment supports diverse marine life and is important for regional tourism and fisheries. The plant plays a key role in protecting coastal water quality and preventing eutrophication in the sensitive Mediterranean ecosystem.
Environmental context
The STAGNONI plant discharges into the Ligurian Sea, a basin of the Mediterranean Sea. This coastal area supports diverse marine ecosystems, including seagrass meadows and fish nurseries, and is a popular tourist destination. Proper wastewater treatment is critical to prevent nutrient pollution and protect water quality for both ecological and recreational uses.
