The Solution To California's Droughts Could Be Drinking Seawater

How does California tackle a five-year-long drought? By turning seawater into the kind you can drink. Carlsbad's 2.2-hectare desalination plant in San Diego County pumps out 200 million litres of water a day, supplying 300,000 residents and businesses. Further north, in Santa Barbara, a second plant will supply 30 per cent of the city's water by early 2017.
