San Franciscans’ water will be delivered exclusively from local storage facilities for at least a month.
A scheduled shutdown of the pipes that deliver water to the Bay Area from Hetch Hetchy Reservoir in Yosemite National Park has begun, the San Francisco Public Utilities Commission announced Tuesday.
The shutdown will allow work to be undertaken on the $4.6 billion, 12-year Water System Improvement Program, which aims to upgrade and maintain the water delivery and storage system and protect it from earthquakes.
The shutdown is expected to last until mid- to late-February.
In anticipation of the shutdown, the flow of water from Hetch Hetchy into Bay Area reservoirs was dramatically increased in recent weeks.
Water supplies for residents are businesses are not expected to be affected, although the water might appear temporarily cloudy after it flows out of a tap due to tiny bubbles that are not normally present.
