Colorado River provides 5.2 million acre-feet per year (AFY)
Carlsbad Desalination Plant will provide 56,000 AFY
Recycled Water – Today’s landscapingTomorrow’s resource?

Water + Plastic
• AB 1998– No plastic bags in
California– 5 ¢ per recycled paper
bag• The American
Chemistry Council– Reusable bags and the
bacteria scare
