Cal Water, the largest subsidiary of California Water Service Group, has signed an agreement to partner with the city of Sunnyvale, California, Santa Clara Valley Water District and Apple on a recycled water project that will provide more than 157,000 gallons per day of recycled water to the sustainable, flying-saucer shaped Apple 2 Campus in Cupertino.

Cal Water will invest $1.5 million in the $17.5 million project, and will provide water utility services to the new Apple campus. New recycled water supplies are expected to be available in the fall of 2016.
