2019 Annual Water Quality Report


The San Francisco Public Utilities Commission (SFPUC) produces these annual reports detailing where your water comes from, how we treat it, and its overall chemical composition. We do this as a regulatory requirement, and we think it is important for you to understand the information within it.

We are committed to providing high quality drinking water for all our customers.

Our system is large and we work across several counties to maintain the system that delivers our water. In addition to the wider system outside of San Francisco, we also maintain a system of reservoirs within San Francisco. It is our hope that these reports will not only provide you with greater knowledge of your water, but also an increased understanding of the considerable skill, talent, and effort that goes into ensuring businesses and residents have reliable access to this precious resource. We’re proud of our water, and we hope you are too. Throughout these reports, you’ll find facts and figures to help expand upon the basic information we’re required to provide. We hope you enjoy getting to know a little more about who we are as an Agency and how you can get involved.
