Registering for My GWW

My GWW is your new place to manage your water account from anywhere, 24/7. Registering is simple.

To get started, you’ll need your 10-digit Greater Western Water account number. You'll find this number on your latest water bill. If you need access to My GWW before then, please contact us.

If you previously used MyAccount or My Water, you need to register for a My GWW account. Your current log in details for MyAccount or My Water won’t work for My GWW. Download our instructions:
