A Poseidon ocean desalination plant would an extensive amount of energy, whereas conservation and recycling water such as done at the OC Water District is less energy intensive. And our marine resources are too valuable to lose. In the future, perhaps as the technology improves, ocean desalination may be an option, but there is plenty of groundwater for the OCWD now, and plenty of opportunity for conservation. Look at your neighbors; are they growing drought tolerant plants? Are they using water efficient appliances? If not, we can count on water conservation to supply water for years.
