Can I Drink Tap Water in Rome?

Rome boasts one of Europe's highest-quality water systems, with 97% of its supply coming from natural springs, primarily the Peschiera-Capore aqueduct in the Apennine Mountains. ACEA, the city's water operator, conducted nearly 420,000 analytical checks in 2023, with compliance rates between 96% and 100%. The water is rich in beneficial minerals like calcium and magnesium, making it hard but perfectly safe. Over 2,500 nasoni (cast-iron drinking fountains) deliver the same monitored water that flows into homes, giving residents and tourists free access to clean drinking water on virtually every block.

Rome's drinking water infrastructure is managed by ACEA ATO 2, which oversees collection, treatment, and distribution for the entire metropolitan area. The primary water source is the Peschiera-Capore aqueduct, which draws from a karstic spring at 410 meters above sea level in the Apennine Mountains, supplying over 80% of the city's water. The remaining supply comes from additional springs and wells. Because the water originates from deep underground springs filtered through limestone, it requires minimal treatment compared to cities relying on surface water. Standard treatment includes chlorination at legally mandated minimum levels (0.2 mg/L), filtration, flocculation, and UV disinfection at key points in the network. In the broader Lazio region, volcanic geology can cause elevated fluoride, arsenic, and vanadium in local groundwater. However, ACEA has addressed this through decommissioning affected local sources and replacing them with higher-quality spring water, bringing all parameters well below EU legal limits for Rome's distribution network. The 2023 sustainability report confirms 419,940 analyses were conducted across the ATO 2 service area, covering chemical, microbiological, and physical parameters. The water is certified under ISO/IEC 17025 laboratory accreditation standards. Rome's famous nasoni fountains, first installed between 1872 and 1874 by mayor Luigi Pianciani, are directly connected to the main distribution network. They run continuously, providing the same tested and treated water that reaches household taps. The water is notably hard (above 16.8 dH, approximately 300 mg/L as CaCO3) due to its passage through calcium-rich geological formations, which gives it a distinctive mineral character but poses no health risks.

Rome's tap water is excellent for travelers. There is no need for bottled water, water purification tablets, or special precautions. The extensive network of nasoni fountains means you are never far from free, fresh drinking water. The mineral-rich composition is actually beneficial for hydration. If you are accustomed to very soft water, you may notice the harder taste, but this reflects healthy mineral content, not contamination.
