10: Italy
Italy ranks #10 for the cleanest drinking water due to its strong infrastructure and strict public health oversight. Most of its tap water comes from springs, rivers, and protected alpine sources. These natural supplies stay clean with minimal treatment. Local water utilities test the water frequently and follow strict safety rules. As a result, over 99% of the population has access to safe drinking water, according to WHO and OECD data. Additionally, Italy’s decentralized management system allows local agencies to address water issues quickly. In many cities, including Rome, residents drink water straight from historic public fountains. While bottled water remains common, most Italians trust their tap water completely. Thanks to consistent regulation and abundant natural sources, Italy delivers clean water from the Alps to the coast.
