Every year, millions in the Bay Area rely on water flowing through the Mountain Tunnel from Hetch Hetchy Reservoir in the Sierras. Designed in the early 20th century, this tunnel is vital for both drinking water and hydroelectric power. To ensure its continued function, the San Francisco Public Utilities Commission's (SFPUC) Water Enterprise conducts annual maintenance and upgrades.

Congrats to Robin Scheswohl and Sabrina Wong, the talented staff photographers of the San Francisco Public Utilities Commission (SFPUC), who were recognized for their skills by industry trade magazine Engineering News-Record (ENR).

Leaky faucet? Running toilet? High water bill? March 17-23, 2025, is Fix a Leak Week and there’s no better time to find and fix leaks as soon as possible! Leaks can happen anytime in any device that uses water. Unchecked leaks waste a valuable resource we all need and share.

Women have been historically underrepresented in the energy industry, and while strides have been made, women only make up approximately 20% of the energy workforce. Here at the San Francisco Public Utilities Commission (SFPUC), we are lucky to have amazing female leaders who continue to push the needle and advance gender equity.

With wildfires becoming an increasing threat across California, emergency preparedness is more important than ever. In San Francisco, our multi-layered water system is designed with built-in redundancies to ensure hydrants remain operational and firefighters have reliable access to water when it’s needed most. In fact, they can even draft saltwater from the Bay if called upon!
