3 environmental groups take 3 positions on Poseidon desalination plant – California Among attributes of the controversial Poseidon desalination plant proposed for Huntington Beach is the $1.5 million or so it would spend annually to keep the tidal inlet open at the Bolsa Chica wetlands, five miles up the coast from the project site. But as much as the money is needed there, the three non-profit groups dedicated to the wetlandsâ preservation clash when it comes to support for the desalter plant. The state spent $151 million to create the inlet in 2006, restoring the estuaryâs interaction with the ocean and revitalizing the wildlife habitat. The work has been a particular boon to the population and variety of birds. (LINK). HIWI042021-05-14T13:53:48+02:00
