Final vote on proposed desalination plant permit in Huntington Beach expected in April – California The Santa Ana Regional Water Board held a workshop on Dec. 6 on the permit renewal of Poseidon Water’s proposed Huntington Beach desalination project; the permit is on pace for a final vote in April 2020. Poseidon Water is seeking to build a $1 billion desalination plant on a 12-acre parcel at the current AES Huntington Beach Generating Station on Newland Street. Previous permits were issued in 2006 and 2012, under which no construction took place. The proposed permit is the third generation of the discharger’s permit. The facility would produce an average volume of 50 million gallons per day (MGD) of potable water from salt water from the Pacific Ocean through a reverse osmosis process. The plant would use the AES intake and discharge systems, but would be required to modify the systems to reduce intake and mortality to all forms of marine life before beginning operation.
