Overview
Porto d'Arzino wastewater treatment plant serves Santi Cosma e Damiano, Lazio, Italy. It is located within 50 km of the coast and operates under EU regulations for small agglomerations.
The Porto d'Arzino wastewater treatment plant is located in Santi Cosma e Damiano, in the Lazio region of Italy. It serves a population of approximately 7,000 people, classifying it as a small agglomeration under European Union standards. The plant is situated near the Tyrrhenian Sea coast, within 50 km of the shoreline, and its operations are subject to Italian and EU environmental regulations. As a small-scale facility, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size discharging into coastal waters. The designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest infrastructure footprint. Typical plants in this region employ biological treatment to reduce organic load and nutrients before discharge. The plant's discharge ultimately reaches the Tyrrhenian Sea, a key Mediterranean basin. The local watershed includes the Garigliano River and surrounding coastal plains, which support diverse aquatic life and agricultural activities. Proper treatment is essential to protect the marine environment from nutrient pollution and to maintain water quality for tourism and fisheries in the region.
Environmental context
The Porto d'Arzino plant discharges into the Tyrrhenian Sea via local waterways, likely the Garigliano River basin. This coastal area supports sensitive marine ecosystems, including seagrass meadows and fish nurseries, which are vulnerable to nutrient enrichment and contaminants. The plant's proximity to the coast (within 50 km) underscores the importance of effective treatment to prevent eutrophication and protect the Mediterranean's biodiversity.
