Fall in Love (With SF Tap Water): Four Reasons to Drink Tap Water

Reason #1: It Tastes Better
Now there is a new reason to think outside of the bottle. According to San Francisco food critics, San Francisco’s tap water tastes better than bottled water. In a recent taste test conducted by the San Francisco Public Utilities Commission, (SFPUC), Arrowhead bottled water was identified by four of the five tasters as inferior. Tara Duggan, a San Francisco Chronicle food writer, described the Arrowhead water as “flat.”
Reason #2: SF Water is High Quality

Reason #3: Better for Your Pocketbook
Switching to tap water is better for your pocketbook. Jue stressed, "Bottled water costs 500 times as much as using tap water.” Gail Lee, UCSF Sustainability Manager added, “Think about it. Bottled water costs more than gasoline or milk per gallon. By making the switch to tap, both at home and at the office, the savings will add up.”
Reason #4: Better for the Environment
The environmental benefits of avoiding bottled water are many. Because 85 percent of San Francisco’s tap water is delivered by gravity from the Hetch Hetchy reservoir, fed by Sierra snowmelt, its carbon footprint is much smaller compared to the energy required to produce and transport bottled water. According to Jue, bottled water uses 2,000 more energy to produce than tap water. It also leaves a wake of waste behind. In California alone, one billion plastic water bottles end up in landfills each year, where they take 1,000 years to biodegrade.
Easy Access at UCSF
UCSF has installed three Global Tap water bottle refilling stations to provide everyone with free access to high-quality Hetch Hetchy tap water while on the go. Global Tap bottle fillers are located at:
• Millberry Union
• Mission Bay Gene Friend Way
• Aldea Community Center
In addition, four bottle filling stations have been created at the following water fountains:
• MSB 1st floor between the two lobby restrooms
• MSB/HSIR 3rd floor near restrooms
• SON 2nd floor corridor
• Between the two restrooms before you enter into the MU Fitness Center
The Office of Sustainability plans to launch a new campaign to encourage UCSF faculty, staff, and students to drink tap water. Stay tuned for more details on how you can easily and cheaply transform a sink or drinking fountain into a tap station for refilling bottles. The tap stations will enable you to reuse your own container rather than depend on bottled water.
