Could desalination solve California’s water problem? - Sacramento Bee
...Along this patch of the Pacific Ocean, welders and pipefitters nearly outnumber the surfers and sunbathers. Within sight of the crashing waves, the laborers are assembling what some hope will make water scarcity a thing of the past.
They are building the Carlsbad Desalination Project, which will convert as much as 56 million gallons of seawater each day into drinking water for San Diego County residents. The project, with a price tag of $1 billion, is emerging from the sand like an industrial miracle. In California’s highly regulated coastal zone, it took nearly 15 years to move from concept to construction, surviving 14 legal challenges along the way....
Reverse-osmosis desalination was invented in California in the 1950s. But other nations with fewer natural freshwater supplies – Israel, Australia, Saudi Arabia and others – embraced the technology first and built dozens of projects over the past few decades. When the Carlsbad plant begins operating in 2016, it will be the largest desalination project ever built in the Americas. Desalination on this scale is so new, said MacLaggan, that Carlsbad will be operated initially by an Israeli subcontractor, which will help train a staff of California workers.
The eyes of a thirsty state are trained on this project: It is a crucial test for an industry eager to expand in California, where residents are famously protective of their coastline and also accustomed to relatively cheap water. In short, the Carlsbad project is challenging California’s status quo while also offering the tantalizing prospect of relief from drought.
“This plant can’t come online fast enough,” said Bob Yamada, water resources manager at the San Diego County Water Authority, which serves 3.1 million people and is buying all of the plant’s freshwater production. “It’s droughtproof. That’s one of the most important attributes. It will be the most reliable water source we have.”
...The state has more than a dozen permitted desalination plants, but they are all small. When Carlsbad begins operating, it will produce about 25 times more drinking water than all of them combined...
