Huntington Beach passes permitting milestone

Poseidon’s Huntington Beach desalination plant project has passed a milestone in permitting after renewing and amending its ocean discharge permit.

The proposed 189,000 m3/d desalination plant will serve the communities around Huntington Beach, Los Angeles

Santa Ana Regional Water Quality Control Board completed the application to amend and renew the permit, and determined that the proposed new plant complies with California’s new seawater desalination regulations.

Project developer Poseidon enhanced the seawater intake and discharge technology on the proposed plant following adoption by California of new rules on the impact on marine life of desalination in May 2015. Since then, Poseidon has submitted 100 reports and technical memoranda in its effort to demonstrate compliance.

The proposed facility in Huntington Beach, Los Angeles, will be the first large scale desalination plant in the world to use 1 millimetre thick seawater intake screens, and to have a through-screen velocity of less than 0.5 feet per second in an open ocean setting.

In October 2016, Poseidon agreed a strategy for permitting the proposed new desalination plant with the California Coastal Commission, California State Lands Commission, and Santa Ana Regional Water Quality Control Board.
