In Donostia, we work for a sustainable-city model… so we want to encourage you to drink water from the tap and from our fountains! If you think about it, drinking tap water is the most affordable, practical and ecological alternative. But what’s more, Donostia’s tap water isn’t only potable. It’s also high-quality, one of the best three in Spain, along with Las Palmas and Burgos, according to the Organisation of Consumers and Users (OCU).
