Registering for My GWW

Residential customers

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 next 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:

If you’re a new residential customer, you can sign up for My GWW once you receive your first quarterly bill.

Business customers

We’re working to bring My GWW to you soon.

Your new My GWW business account will launch later in 2024 and we’ll keep you updated as things progress. Read more about the changes we’re making for you.
