Planning Major Projects - Poseidon Desalination Plant

Project Name: Poseidon Desalination Plant

Applicant: Poseidon Resource Corporation

Location: 21730 Newland Street

Project Summary

The project, proposed by Poseidon Resources Corporation, consists of the construction and operation of a 50 million gallon per day seawater desalination facility within the City of Huntington Beach. The facility would consist of seawater intake pretreatment facilities, a seawater desalination plant utilizing reverse osmosis technology, product water storage, two pump stations, materials storage tanks, and 42 to 48-inch diameter product water transmission pipeline possibly up to 10 miles in length in Huntington Beach and Costa Mesa. The facility would utilize existing AES Huntington Beach Generating Station (HBGS) seawater intake and outfall pipelines for its operations. The proposed desalination facility is located on 11-acre portion of the 22-acre HBGS facility located at 21730 Newland Street, off Pacific Coast Highway. The Environmental Impact Report was certified by the City Council on September 7, 2010.  The City Council also approved the entitlement plan amendment, coastal development permit, and tentative parcel map for the project in September 2010.  The coastal development permit is on appeal at the Coastal Commission.
