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.
