Document Description
The project involves the construction and operation of a 50 mgd seawater desalination plant within the City of Huntington Beach. The proposed site is located on a 3.9-acre portion of the 22-acre AES Huntington Beach Generating Plant located at 21730 Newland Street. An alternative location is under consideration to the immediate north of the proposed project site on land currently owned by Southern California Edison (SCE). The proposed desalination plant would consist of seawater intake pretreatment facilities, a seawater desalination plant utilizing reverse osmosis technology, product water storage, two pump stations, and 24 to 48-inch diameter product water transmission pipelines of up to 10 miles in length. The facility would utilize existing AES intake and outfall pipelines for facility operations.
