Can You Drink the Tap Water in Warsaw?

Complete Tap Water Safety Guide for Warsaw

Tap water in Warsaw is safe to drink and meets European Union water quality standards. The city's water is sourced mainly from the Vistula River along with groundwater, treated at modern facilities, and has improved substantially since Poland joined the EU in 2004 brought major infrastructure investment.

Warsaw residents drink tap water regularly, though some prefer filtering it with a simple jug filter, largely due to a mild chlorine taste from treatment rather than any safety concern. The mains supply itself is safe throughout the city, including the Old Town, city centre and surrounding districts.

Older buildings in some parts of Warsaw can have ageing internal plumbing that affects taste, but this does not compromise the safety of the municipal supply. Visitors can drink tap water with confidence throughout their stay.
