Is the tap water safe to drink in the Netherlands?
Yes. In 2023, Dutch drinking water met the standards in 99.9% of 565,689 measurements, according to the national inspectorate, and WHO and UNICEF put safely managed drinking water at 100% for 2024.
What the official figures say
Dutch tap water reaches you without chlorine, which is rare anywhere in the world. It's treated so that bacteria find little to grow on in the pipes, and ultraviolet light replaced the last chlorine step in 2005.
When something is found, households are told. In November 2023, a single E. coli finding led to boil-water advice for about 30,000 households in Assen and Rolde.
Why a public tap can still be different
A tap in a park or at a station depends on its own pipes and how often it's cleaned, and water that has been sitting in an unused tap should be run off first.
Check the tap, then tell the next person
Let the tap run for a few seconds and check the spout. When a tap is worth using, add it to Fontavio or review it; anyone cycling across the country will be glad to know where to refill.
