Can Brits drink tap water in Barcelona?

According to General de Sanidad (the government agency that looks after the tap water in Spain) and Aig?es de Barcelona (the local water company) it's potable (drinkable) according to all international standards including the EU and WHO.



Yes, British travelers—and all visitors—can safely drink the tap water in Barcelona. In 2026, the city's water quality continues to be regulated by strict European Union standards and is meticulously monitored by the local provider, Aigües de Barcelona. The water undergoes a rigorous multi-stage purification process, including ozonation, ultrafiltration, and reverse osmosis. While the water is chemically and biologically safe, many Brits might find the taste slightly "different" or "metallic" due to the high mineral content, as Barcelona is known for having "very hard" water. If the taste is off-putting, using a simple filter bottle or buying bottled water is a common preference, but for brushing teeth or basic hydration, the tap water is perfectly potable. Additionally, the city has over 1,700 public drinking fountains that provide free, safe water to residents and tourists alike.
