Reverse osmosis drinking water in San Francisco, CA.

Under-sink reverse osmosis equipment for San Francisco homes from $499, with whole-home options also available by request. Installation is quoted and paid for separately.

San Francisco's tap water is supplied by the San Francisco Public Utilities Commission (SFPUC), primarily through the Hetch Hetchy Regional Water System.

The city's water is generally soft and is disinfected with chloramine. For details about the municipal supply, read the SFPUC's annual water-quality report.

Your building's plumbing can also influence water at the tap. If you have concerns about lead or older pipes, SFPUC's testing information can help you explore next steps.

What San Francisco homes are dealing with

Customers may be interested in drinking-water taste, reducing bottled-water purchases, or understanding concerns about older plumbing. Your preferences and home setup help guide the conversation.

We review published SFPUC information, discuss your household and kitchen, and explain the equipment options and their documented capabilities. A utility report does not consider the water at your individual tap.
