Overview
ARENZANO wastewater treatment plant serves approximately 15,000 people in Arenzano, Liguria, Italy. Located near the coast, it operates under EU Urban Waste Water Treatment Directive standards.
The ARENZANO wastewater treatment plant is located in Punta San Martino, Borghetto, Arenzano, in the province of Genova, Liguria, Italy. It serves a population of around 15,000 residents, placing it in the medium agglomeration category under EU classification. As a plant in Italy, it 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), indicating it is sized appropriately for its service population. The plant is situated within 50 km of the coast, and its treated effluent likely discharges into the Ligurian Sea via local watercourses. This coastal discharge requires compliance with sensitive area provisions under the EU directive to protect marine water quality and the diverse aquatic life of the Mediterranean ecosystem.
Environmental context
The plant discharges into the Ligurian Sea, part of the Mediterranean Sea, which supports diverse marine ecosystems including seagrass meadows and coral habitats. The local watershed includes small coastal streams that drain the Ligurian Apennines. Protecting this coastal environment is critical for tourism, fisheries, and biodiversity conservation.
