In this Wednesday, July 29, 2015 photo, Jason Dadakis of the Orange County Water District talks about the water filtration system at their water treatment plant in Fountain Valley, Calif. Earlier in the year, the facility expanded to produce 100 million gallons of water each day. That's enough to supply 850,000 people, even after some is injected into wells that form a barrier against the intrusion of ocean water into the aquifer. (AP Photo/Chris Carlson)
