Source of Water in San Francisco, California
San Francisco tap water comes from surface water and a few percentages on groundwater. San Francisco’s source of water originates from the Tuolumne River and collected in the Hetch Hetchy Reservoir. Water from the Hetch Hetchy enriched with water from local watersheds such as the Alameda, Peninsula, San Andreas, and Pilarcitos reservoirs. Emergency supplies include Lake Eleanor, Lake Cherry, and streams of the Lower Cherry Aqueduct, Early Intake Reservoir, and Tuolumne River.
Avoiding bottled water can benefit the environment in many ways. About 85 percent of San Francisco’s tap water is produced by gravity from the Hetch Hetchy reservoir, supplied by Sierra snowmelt, its carbon footprint is much smaller compared to the energy needed to create and transport bottled water. Mentioned to Jue, bottled water does 2,000 more power to create than tap water. Bottled water also leaves a wake of waste. Singly in California, one billion plastic water bottles end up in landfills each year. It will take 1,000 years to biodegrade plastic bottles.
