Dam Safety Upgrades
State Water Corporation dams were built in full compliance to the best engineering standards and practices at that time. In order to remain compliant, it is now necessary to upgrade 
seven major dams to ensure our assets continue to operate in line with evolving international standards.
The dam upgrades will:
- Ensure public safety.
- Ensure dams maintain compliance with the NSW Dams Safety Committee.
- Ensure our dams are managed in accordance with standards set by the Australian National Committee on Large Dams.
- Maintain the highest levels of dam safety.
- Accomodate latest developments in geotechnical and dam engineering.
- Cater for revised "extreme" rainfall projections from the Bureau of Meteorology.
More than $250 million will be injected into regional economies throughout NSW, supporting jobs and bringing new, unique skills to communities surrounding the dams as a result of the dam upgrades.
