Can I Drink Tap Water in Prague?

Prague has a modern municipal drinking-water system with transparent public information from PVK/PVS. PVK's Prague distribution system information describes a large network serving roughly 1.4 million people, with thousands of kilometers of pipelines, water tanks, and pumping stations. PVK also publishes pages on drinking water and water quality questions, and Prague tap water is generally considered safe for direct drinking in normal homes, hotels, and restaurants.

Prague's tap water is supplied through a large municipal system managed by Prague Water Supply and Sewerage entities (PVK/PVS). PVK's public “Clean Water for Prague” materials describe a city network serving approximately 1.4 million inhabitants with extensive infrastructure, including thousands of kilometers of distribution pipes, dozens of pumping stations, and water tanks. This is not a small or informal system; it is a major urban utility network designed for continuous supply and monitoring. PVK also publishes consumer-facing pages on drinking water and FAQ responses about water quality. In practical travel terms, Prague is considered a safe tap-water city. The main differences visitors notice are usually taste (including light chlorination or mineral variation) and the condition of older internal building plumbing rather than city-wide safety problems. Tap water is generally safe for drinking, brushing teeth, and restaurant use, while bottled water remains optional for convenience or taste preference.

Prague is a low-risk destination for tap water. Travelers can usually drink directly from the tap, brush teeth with tap water, and accept ice in restaurants without concern. If a specific building has old plumbing and the water appears discolored after stagnation, flush it and use bottled water temporarily, but that is a local issue rather than a city-wide safety problem.
