A municipal-grade water-treatment system promises to yield irrigation water for a British Columbia winery this year. Tantalus Vineyards installed a sequencing batch reactor (SBR) last year as part of the development of a new, 13,000-square-foot winery building that’s seeking LEED (Leadership in Energy and Environmental Design) certification. The treatment plant, designed by Enviro-Stewards Inc. of Elmira, Ontario, occupies a compact, 900-square-foot building next door.
