Short answer: Officially, yes — Moscow's tap water is treated to national potable standards and monitored around the clock, and the water leaving the city's treatment plants meets European quality benchmarks. In practice, most locals still drink filtered or bottled water because old building plumbing can affect what actually comes out of the tap. As a visitor, the safe and easy choice is bottled water, which is cheap and sold everywhere.
The official position
Moscow's water utility, Mosvodokanal, treats the city supply through modern processes at stations such as Rublevskaya and Zapadnaya — including ozonation, activated-carbon and (at some stations) membrane filtration, plus a switch from liquid chlorine to safer sodium hypochlorite for disinfection. Quality is checked continuously against roughly 200 physical, chemical and biological indicators on the water's way to the consumer, using more than 600 automatic analysers running 24/7 — well over a million analyses are carried out each year. Over the past two to three decades, measurable quality has improved significantly, with turbidity and other markers falling sharply. By the official numbers, the water is safe.
The real-world caveat
The catch is what happens after the treatment plant. Clean water can still pick up impurities in the distribution network and building-level pipes, especially in older apartment blocks and hotels where plumbing may be decades old. That is why Moscow authorities describe the water as technically drinkable while most locals and health experts still recommend a filter. You may also notice a mild chlorine taste, and quality can vary noticeably from one district — or one building — to the next. Visitor surveys reflect this split: perceived water quality rates as "high", yet people still voice caution about the tap.
What should a tourist actually do?
- Drink bottled water. It is inexpensive and sold in every shop, kiosk and supermarket. Ask for вода без газа (still) or вода с газом (sparkling). Pay in cash or with a Mir card.
- If your stomach is sensitive, or you're visiting in summer, stick to bottled or boiled water — boiling for a minute kills microbes and is a common local habit.
- Use a filter if you're staying a while in an apartment; jug filters are cheap and sold in any supermarket.
- Brushing teeth with Moscow tap water is generally fine for short stays.
- Ice and hot drinks in reputable cafés and restaurants are safe — venues use filtered or treated water.
- Hotels often provide a kettle and complimentary bottled water; many restaurants serve filtered water on request.
