Drought Response

The LHWP has actions to maintain the region's water supplies through a drought. The table below shows how measures will be activated as water storage levels fall.

  • Water Wise Rules will apply – these are common sense actions to help conserve water every day.
  • Water can be transferred between the lower Hunter and the Central Coast depending on the storage levels in each region.

  • Further investigations and 'readiness activities' will be undertaken on drought response desalination to enable a quick response if needed in an extreme drought (such as construction of the Belmont temporary desalination plant).
