Dam projects across NSW

Water Infrastructure NSW is committed to delivering long-term water security projects that improve water security and build the drought resilience of our regional communities.

Dams are critical infrastructure projects that improve water security and reliability by increasing the volume of water that can be stored during wet periods.  This provides crucial long-term water supply, which helps protect against water shortages during drought.

In partnership with the Australian Government, the NSW Government is currently investigating three dams critical to improving the resilience and water supply for regional communities in NSW. These projects have been identified as Critical State Significant Infrastructure under the Water Supply (Critical Needs) Act and work is currently underway to prioritise the development of this proposed infrastructure.

If approved, these dams will be one of the largest investments in water supply infrastructure in NSW and will provide a range of regional communities with more reliable, secure and resilient water supplies for future generations.
