Stone Brewing unveiled its Stone Full Circle Pale Ale, the first local craft beer brewed with advanced-treated recycled water from the City’s Pure Water facility. Pure Water is high-quality recycled water that will become part of the City’s drinking water supply beginning in 2021. The Pure Water San Diego program is designed to purify enough wastewater to provide one-third of San Diego's water supply and is estimated to be fully operational by 2035.
