How Does Water Safety Work in Hong Kong?
Last verified: 2025-06 · Asia
1The Quick Answer
Tap water in Hong Kong is safe to drink as it is treated and regularly tested, though many locals prefer filtered water due to older building pipes.
2What You Need to Know
Hong Kong's municipal water supply meets international standards and is technically safe to drink straight from the tap. The Water Supplies Department conducts regular quality testing. However, many local residents use filtered or bottled water out of concern that older building pipes (common in pre-1980s buildings) can affect water quality after it leaves the mains supply. For tourists staying in modern hotels, tap water is generally fine to drink. Bottled water is cheap and widely available at 7-Eleven and convenience stores throughout the city.
