A water treatment company in San Francisco has partnered with a brewery to create a beer made with recycled water from a residential building .​ Epic Cleantec​ partnered with​ Devil's Canyon Brewing Co.​ to craft Epic OneWater Brew, a Kölsch-style ale made with recycled greywater. ​ The building has a greywater reuse system designed to recycle 7,500 gallons of water per day, or up to 2.75 million gallons per year. The system is the​ first approved and operational greywater reuse system​ in San Francisco. ​ In September, Epic Cleantec transported over 2,000 gallons of this recycled water to Devil's Canyon Brewing Co. to begin it's two-week transformation into beer. The beer is not available to purchase, as current regulations prohibit the use of recycled wastewater in commercial beverages.
