Sirens

Sunwater has installed dam emergency warning systems (sirens) at six locations across Queensland.

Please note that the sirens are not currently active for use. Sunwater is working with Councils to determine how the sirens will be used and the warnings that follow.

The siren will notify residents in the highly unlikely event of a dam failure. The siren will not be activated in the event of water releases or downstream flooding.

They can provide verbal instructions or make a traditional siren sound to an audible radius of three kilometres. Siren warnings are in addition to our existing emergency SMS notifications.

Even though dam failure is incredibly rare, we’re taking precautions to ensure our community is safe.

Dam failure might occur if a dam wall is damaged and releases uncontrolled large volumes of water. Common causes might include large earthquakes or erosion of the surrounding land.

Dam failures are extremely rare. In Australia there has only ever been one instance in the past 90 years.
