Success Story: Napa Valley Winery
Reusing 1+ million gallons
of water year after year
When its leach field failed, the owners of a Napa Valley winery knew it was time to reconsider their wastewater system. A series of droughts resulted in increased water-use restrictions, which led California wineries to look for ways to treat and reuse wastewater. A Napa winery found the perfect match for their sustainability goals with customized Xerxes® tanks, with the added benefit of the complete corrosion resistance needed for the chemicals and varied pH levels contained in winery wastewater. From the first year of operation, it paid off, with the winery treating and reusing 1.35 million gallons of water – the amount of water they would have had to source from somewhere else. In the words of the winery manager: “Our water now has two life cycles.” That’s a success by all measures.
