Early Warning Network
We utilise the Early Warning Network (EWN) to deliver notifications and alerts for dam and supply activities, significant dam releases and in emergency situations.
The Early Warning Network gives you the option to receive personalised notifications to both your email and/or via phone, either landline or mobile via SMS. This ensures you receive the alerts relevant to you, when you need them.
To receive alerts, first register with EWN by completing the WaterNSW EWN Registration Form where you will select the notification category of interest with a location of interest.
Registeration Options

This is the preferred method.
Registering using an email address will automatically create for you an online account and password. You can use these details to log on at any time to update/change your details, notification selections and manage your preferences
Register using a phone number (mobile or landline)
If you do not have an email to register with, you can register using your phone number, landline or mobile.
After completing the registration form, you will receive a call verifying your identity. This form of registration does not give you an online account and you need to contact 1300 662 077 and Customer Service can update your details for you.
