Hetch Hetchy Aqueduct
From Wikipedia, the free encyclopedia
The Hetch Hetchy Aqueduct is 167 miles long. It delivers water from the Hetch Hetchy reservoir in Yosemite National Park to the City of San Francisco and other suburban municipalities in the greater San Francisco Bay Area.
Typical flow rates are on the order of 270 to 315 million gallons per day. The aqueduct splits into four separate Bay Division pipelines at the point where it reaches the city of Fremont. These are called Bay Division Pipelines (BDPL) 1, 2, 3, and 4, with nominal pipeline diameters of 60, 66, 78, and 96 inches, respectively. All four pipelines cross the Hayward fault. Pipelines 1 and 2 cross the San Francisco Bay to the south of the Dumbarton Bridge. Pipelines 3 and 4 run to the south of the bay.
