Zócalo Public Square

California's historic drought has forced local communities to find new water supplies. But where? Some coastal cities are looking to the ocean, contemplating desalination projects that once were dismissed as too energy-intensive and expensive. Meanwhile, some counties have looked to the toilet--turning sewage into drinking water in a process called toilet to tap. At an event co-presented by Occidental College, West Basin Municipal Water District public information and conservation manager Ron Wildermuth, Orange County Water District president Shawn Dewane, Water Wise president Sarah Woolf, and Cadiz Inc. president and CEO Scott Slater talked with Bob Sipchen about whether Southern Californians will be drinking ocean water or wastewater in the coming years.
