The county may need less water than once projected, but the Orange County Board of Supervisors made it known Tuesday that it still supports construction of a proposed $1 billion Huntington Beach desalination plant.

One week after the Municipal Water District of Orange County projected that the county’s water demand in 2040 would be 17 percent lower than previously estimated, supervisors voted to reaffirm their support for the desal plant and urged the California Coastal Commission to approve the project’s final permit.
