What residents and travelers say

San Francisco's tap water is often praised for its clean taste and quality, largely attributed to its source in the Hetch Hetchy Reservoir. However, experiences can vary significantly depending on the neighborhood and even individual buildings. Many residents report enjoying the water straight from the tap due to its mineral profile, which is often described as crisp and fresh. Still, others prefer to use filters, mainly for taste preferences or concerns over older plumbing that might affect water quality at the point of use.

Visitors and locals alike note that while most areas in San Francisco boast reliable water quality, some older buildings might show differences in taste or clarity, prompting use of home filters. Common filtration choices include simple carbon filters that reduce odor or slight off-flavors, which can be more prominent in certain parts of the city. Additionally, refill norms generally support using tap water; reusable bottles are common among environmentally conscious residents, and refill stations are available at many public spots.

For the most accurate and up-to-date information about water quality and any advisories, it’s best to consult official sources like the San Francisco Public Utilities Commission (SFPUC), the San Francisco Department of Public Health, or check real-time updates via the San Francisco Public Utilities Commission on Twitter.
