Can You Drink Tap Water in Portugal?

Tap water in Portugal is safe to drink throughout the country and meets European Union water quality standards. In Lisbon, Porto, Faro, Coimbra, and all Portuguese cities, tap water is treated to EU standards and safe for consumption. Most Portuguese people drink tap water regularly and visitors can do the same confidently. Lisbon's tap water comes from protected reservoirs north of the city, is comprehensively treated, and meets all safety requirements. The water may have a chlorine taste which is normal and indicates treatment.

Porto and northern Portugal have excellent tap water quality with good infrastructure. The Douro Valley, despite being a wine region, has safe tap water throughout. The Algarve including Faro, Albufeira, Lagos, and coastal resort areas has safe tap water that meets EU standards. Some areas use desalination during summer months due to tourism demand, but water remains safe. Madeira and the Azores islands have safe tap water throughout.

Madeira's mountainous terrain provides excellent water sources, and tap water is safe in Funchal and across the island. The Azores similarly have good water quality. In rural areas of Portugal including Alentejo and inland regions, tap water meets safety standards though some villages may have older infrastructure. Throughout Portugal, tap water can be used for drinking, brushing teeth, making ice, and cooking.

Despite safe tap water, many Portuguese prefer bottled water for taste preferences and this is a common cultural practice. Restaurants typically serve bottled water but tap water can be requested. Portugal's water infrastructure has improved significantly since joining the EU.
