An Israeli company is to build a $5.5 billion desalination plant in Mexico, to supply the US state of Arizona with drinking water. 

The desalination plant will be connected to a water distribution facility and reservoir in Arizona through a 1,000 ft-long series of pumps and pipes. It will draw water from the Sea of Cortez, desalinate it, and provide up to one billion cubic meters a year to Arizona.
