The Orange County Water District delayed voting Wednesday on updated terms for buying water from the proposed Huntington Beach ocean desalination plant. Board members wanted more time to review the rate plan and gather additional community feedback on an updated rate sheet, which was made public Friday with the meeting agenda. Several community members, environmental activists and water district representatives raised concerns. The 10-member board voted unanimously to reconsider the proposal July 18. If approved, the non-binding, updated term sheet would shorten the length of the contract between the water district and Poseidon Water from 50 years to 30 or 35 years.
