A proposed desalination plant in Orange County could get a boost from President Donald Trump’s administration, but not everyone is happy about that. The Poseidon Water Company has wanted to build the Huntington Beach Desalination Project, but it has been tied up in red tape for more than a decade. The proposed desalination plant popped up on an allegedly leaked Trump administration list of 50 infrastructure projects.Opponents of the project said the state has shot down the plans for the past 17 years because it’s environmentally unsound and too expensive to desalinate water.
