Ocean or seawater desalination is an option. However, creating pure water from saltwater comes at a price, and the biggest cost is in terms of energy and equipment. It requires significant energy to remove the salt from the ocean water, and there is much more salt to be removed than required to purify recycled water for potable reuse, meaning more equipment to filter out that salt. While potable reuse is anticipated to cost approximately $1,600 to produce an acre-foot of water, desalination can cost in excess of $2,500 to $3,000 an acre-foot, depending on the ultimate size of the full-scale treatment plant and distribution piping.
