·      How about the water quality?

I love drinking tap water and according to San Francisco Water Power Sewer company, “San Franciscans currently enjoy high-quality, great tasting water from the Hetch Hetchy Regional Water System”. Also, “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”.
