Tap water in Lisbon is safe to drink and meets stringent European Union quality standards. While technically drinkable and subject to rigorous quality controls, residents and visitors often find the taste less appealing due to mineral content and chlorine, leading many to prefer bottled water or filtered tap water. Some older buildings may have plumbing that affects water quality, but overall, Lisbon tap water is potable and safe for consumption.
Safety and Quality
Lisbon's tap water is treated and monitored by Empresa Portuguesa das Águas Livres (EPAL), ensuring it complies with EU regulations for chemical and microbial safety. Approximately 99% of Portugal's water, including Lisbon's, is classified as safe for consumption, with extensive water quality testing conducted regularly.
Taste and General Preference
Despite safety, many locals and tourists prefer bottled water because Lisbon's tap water can have a strong taste from minerals and chlorine. Additionally, older pipes in some buildings may impart an unpleasant taste or minor discoloration without compromising safety. Filtration systems are recommended for those who want to improve taste quality.
Regional and Building Considerations
Tap water quality can vary slightly depending on the building's plumbing infrastructure, with older buildings potentially affecting taste or minor contamination risks. Public water sources in Lisbon, such as fountains, are tightly controlled and considered safe.
In conclusion, drinking tap water in Lisbon is generally safe, legal, and common, though taste and aging infrastructure may cause some people to prefer bottled or filtered water.
