Can Desalination Projects Remedy California's Drought Problem?

Published on May 29th, 2009 | by

The scarcity of water in California has reached astounding levels. The state is looking to various means and resources to remedy this situation. According to Scripps, about  20 water agencies up and down the California coast are favoring desalination projects as a method to deal with drought.

“People are worried about water supply,” said Michael Carlin, assistant general manager of water at the San Francisco Public Utilities Commission. “Desalination is for drought supply, for an emergency, and it augments existing supply — it’s another tool in our toolbox.”

Poseidon Resources, a Connecticut based water  infrastructure development company, has recently gained approval from California state regulators to build the Western Hemisphere’s largest desalination plant in Carlsbad (near San Diego). The $300 million Carlsbad Desalination Project will have significant economic benefits for the region, including an estimated $170 million in spending during construction, 2,100 jobs created during construction and $37 million in annual spending throughout the region once the desalination plant is operational.

But desalination is a highly contested issue as many environmentalists regard it as a quick fix that can cause more harm in the long term, than good. The briny byproduct of desalination is typically dumped into the ocean and tends to sink to the bottom as a salty, oxygen deficient plume. This can be detrimental to marine life and fisheries nearby.

Food & Water Watch has put together a list of reasons as to why communities should think twice before diving into desalination projects.  Read more about this here.
