San Franciscans currently enjoy high-quality, great tasting water from the Hetch Hetchy Regional Water System. On average, 85% of this water comes from Hetch Hetchy Reservoir, while the rest comes from local surface reservoirs in Alameda and San Mateo Counties, and, beginning in early 2017, from groundwater pumped from the Westside Basin Aquifer. . Unlike bottled water, our delicious tap water costs less than half a penny per gallon, is quality tested over 100,000 times a year, and goes straight to your tap. In fact, tap water is also highly regulated by the EPA and across state and local water quality standards.
Since 2010, we have installed outdoor water bottle refilling stations ("tap stations") around the City to provide everyone with free access to high-quality Hetch Hetchy tap water while on the go. Our tap stations enable you to reuse your own container rather than purchase costly single-use bottled water. This encourages conserving our natural resources and reduces waste from single-use plastic water bottles.
The next time while you are out and about in the City, remember to bring your reusable container and refill your bottle at any of our tap stations.
