Prepaid Electronic Keys
A prepaid electronic key allows users to access water up to the value of their prepaid credit limit. As you use water, credits are automatically deducted from your account. Users are able to periodically top up their prepaid electronic key. Full instructions on using the prepaid electronic key and accessing water are explained in our Questions and answers.
The prepaid electronic key will cost $59.38 (FY2025/2026) with:
• $20.00 assigned as initial water credit on the electronic key to your primary location
• $39.38 as the deposit for the electronic key.
On the return of the electronic key, TasWater will return your deposit and any credit left on the electronic key. If the electronic key is damaged, you will not be able to access the deposit, but will be issued the credit left on the electronic key.
You can have more than one location assigned to the prepaid electronic key. If your prepaid electronic key is accessing more than one location, you will have to maintain a separate prepaid credit balance at each location that you wish to use. The AVDATA portal will provide credit balances for each location. Please be aware that not all water filling stations are available for the general public, some are only available to registered water carters.
You will need to arrange credit for the prepaid electronic key, including the filling station to which you want the credit assigned to. To access the water filling station and placing credit on the prepaid electronic key, at each location, go to the AVDATA portal at: https://members.avdata.com.au/CustomerPortalRegistrationServlet
Water charges for filling stations are regulated and are set at $1.9444 per Kilolitre (FY 2025/2026).
