Yes, it is safe to drink tap water in Portugal. The tap water across the country, including urban areas like Lisbon, Porto, and tourist regions such as the Algarve, meets the European Union's stringent water quality standards. The water undergoes treatment and purification processes that make it safe to consume without boiling. However, some people may choose bottled water due to taste preferences, as the mineral content and chlorine used in treatment can sometimes affect flavor. In older buildings, there might be concerns about pipes affecting water quality, but overall, tap water is regulated and safe for drinking throughout Portugal.
