"In downtown San Francisco, in a cavernous garage that was once a Honda
dealership, a gleaming white-and-blue appliance about the size of a commercial
refrigerator is being prepared for transport to a hotel in Los Angeles.
There, this unit, called a OneWater System, will be installed in the basement,
where its collection of pipes will take in much of the hotel’s graywater — from
sinks, showers, and laundry. The system will clean the water with membrane
filtration, ultraviolet light, and chlorine, and then send it back upstairs to
be used again for nonpotable uses.
And again. And again.
“There is no reason to only use water once,” said Peter Fiske, the executive
director of the National Alliance for Water Innovation, a division of the
Lawrence Berkeley National Laboratory, in Berkeley. Just as natural systems use
and reuse water repeatedly in a cycle driven by the sun, he said, “we now have
technologies to enable us to process and reuse water over and over, at the
scale of a city, a campus, and even an individual home.”
While centralized water reuse for nonpotable purposes has been around for
decades, a trend called the “extreme decentralization of water and wastewater”
— also known as “distributed water systems,” or “on-site” or “premise”
recycling — is now emerging as a leading strategy in the effort to make water
use more sustainable."
