From toilets to taps: SF tests new water recycling program
Manisha Kothari looked every bit the bartender as she filled a dozen shot glasses, pouring carefully from a slender pitcher.
But what Kothari served on a weekday morning at the San Francisco Public Utilities Commission’s headquarters was not a round of spirits.
It was the culmination of more than a year’s worth of research into how San Francisco might someday tap a new source of potable water, turning what’s now a waste product into clear, cool drinking water. What Kothari, a water resource specialist, filled the glasses with looked, smelled and tasted like what comes out of any city faucet, but it had been harvested from the San Francisco water agency’s toilets, sinks and shower drains.
