Water for people and water for the environment
Dams are our major source of drinking water. However Sydney is no longer totally reliant on rainfall stored in dams because water is also available through desalination and recycling.
Continuing to improve the way we manage dams will provide more drinking water for us and better health for our rivers.
Accessing deep water in our dams has increased the amount of water available by an extra 40 billion litres a year.
Shoalhaven water transfers provided about 30 percent of the supply to greater Sydney during the last drought.
Extracting groundwater could provide up to 30 billion litres of water per year for two to three years during severe drought.
