San Diego County marked a significant milestone in regional water supply reliability Thursday at the Claude “Bud” Lewis Carlsbad Desalination Plant – the delivery of 40 billion gallons of drinking water during its first three years of commercial operations. This is enough water to fill 800 million bathtubs, or 1,820 Bellagio Las Vegas fountains. The plant, which launched its commercial operations in December 2015, provides San Diego County with 50 million gallons of locally-controlled, climate-resilient and high-quality water a day, helping to minimize the region’s vulnerability to droughts.
