Here are the key facts about Greater Western Water at a glance.

Who owns Greater Western Water?

Greater Western Water is a state-owned corporation wholly owned by the Victorian Government. It was created on 1 July 2021 from the merger of Western Water and City West Water (Wikipedia – background on the utility).

Who is the managing director of Greater Western Water?

• The managing director is Maree Lang, who leads the organisation from its Footscray headquarters (Greater Western Water official site).

What is the history of Greater Western Water?

• Formed 1 July 2021 by merging Western Water and City West Water.
• Initially served a smaller customer base; expanded to over 580,000 by 2022.
• Introduced the My Account online portal in 2023 for billing and self-service (per GWW billing page).

Why this matters: The merger created a single utility covering Melbourne’s fast-growing western corridor. Residents now deal with one provider instead of two, but the transition has meant some temporary service changes.

Where is Greater Western Water based?

Greater Western Water’s head office is located in Footscray, Victoria (GWW official site). The service area stretches from Melbourne’s CBD west to Lancefield and the Macedon Ranges, including suburbs like Sunbury and Footscray.

How do I set up direct debit with GWW?

Setting up direct debit with Greater Western Water currently requires a workaround. As of the latest update, direct debit in full service is unavailable and existing agreements have been cancelled (GWW official notice). The utility is working to bring it back. In the meantime, payment plans (weekly, fortnightly, monthly) continue as normal and end automatically after 12 months.

Can you set up Direct Debit online?

• Yes, you can register online at my.gww.com.au using a credit/debit card or bank account (GWW direct debit page).
• Alternatively, you can set up bank-account-only direct debit by phone on 1800 805 301.

What do I need to set up direct debit?

1. Prepare your bank account details (BSB and account number) and your GWW account number.
2. Register online at my.gww.com.au or call 1800 805 301.
3. Choose a payment plan (weekly, fortnightly, or monthly). Ensure sufficient clear funds in your account when the debit is scheduled.

This means customers should use the EasyWay plan while awaiting the restoration of full direct debit.

How do I check my water bill online?

You can view and pay your Greater Western Water bill through the My Account portal at my.gww.com.au (GWW billing page). Registration is free and gives you access to your billing history, payment options, and direct debit settings.

How do I pay my water bill online?

• Log in to My Account and choose credit/debit card or direct debit.
• You can also set up regular instalments via the EasyWay plan.

What is the My Account portal?

• A secure online self-service portal where you can manage your water account, view bills, and update payment methods (GWW).

The trade‑off: The portal is convenient, but you’ll need a stable internet connection and a registered account. For those without online access, GWW also accepts payments over the phone on 13 44 99.

What runs your water bill up the most?

Several factors can unexpectedly increase your water bill. While GWW’s rates are regulated, consumption patterns and household efficiency play a big role. The most common culprits are leaks, outdoor watering, and older fixtures (Victorian Government water efficiency guidance).

Common causes of high water bills

• Leaks (toilet flappers, dripping taps) – often the biggest hidden cost.
• Seasonal outdoor water use – irrigation and pool filling in summer.
• Older fixtures – pre‑2000 showerheads and toilets use significantly more water.

How to reduce your water bill

• Fix leaks promptly – check your water meter after turning off all taps.
• Install water‑efficient showerheads and dual‑flush toilets.
• Use a rain sensor on your irrigation system.

Taking action on leaks and fixtures can significantly lower your quarterly charges.

Timeline

• 1 July 2021: Greater Western Water formed from merger of Western Water and City West Water (Wikipedia).
• 2022: Service area and customer base expanded to over 580,000.
• 2023: My Account online portal introduced for billing and self‑service.

What this means: GWW is a young utility still integrating systems. The current direct debit pause is a symptom of that merger transition – but the long‑term goal is a seamless, digital‑first customer experience.

Frequently asked questions

If you have further questions, consider contacting GWW directly via phone.

For customers in Melbourne’s western suburbs, the key takeaway is this: Greater Western Water is still working through its post‑merger integration, especially on direct debit. If you need a quick fix, use the EasyWay payment plan over the phone. For online self‑service, my.gww.com.au works for viewing bills and paying with a card. The alternative is to wait until the full direct debit service returns – and watch for leaks that quietly inflate your bill.
