Prices and charges explained
Greater Western Water (GWW) is now the water corporation for Melbourne's CBD and western region.
Greater Western Water formed in 2021 by bringing together Western Water and City West Water.
The Victorian Essential Services Commission (ESC) regulates the prices we charge.
Our current prices and charges are based on the price submission determination approved by the ESC for Greater Western Water in June 2024.

To understand how our prices are developed and approved, read our Price Submission or visit the Essential Services Commission website.
Aligning prices across our service area
We want all our customers to experience a similar level of service at a fair and similar price.
To bring our prices closer together, price adjustments were approved by the ESC in the two years leading into our 2024 price submission, and we have engaged with customers on how to best align our prices in the future.
We are working to have a single set of prices and charges for all our customers by simplifying tariff structures and transitioning prices across our service area over time.
In the meantime, we will maintain distinct central and western pricing zones.
What your bills pay for
Your payments contribute to so much more than just the safe, reliable drinking water that comes out of your tap. You’re also helping to pay for the continual upgrade and development of the infrastructure we need to treat and supply water for our growing communities.
Your payments also contribute to:
- the collection, treatment, re-use and disposal of billions of litres of sewage and wastewater
- the delivery and maintenance of thousands of kilometres of water and sewer pipes
- customer service, cyber security and new sustainable technologies
- community support programs and maintaining waterways, local parks and green spaces.

Part of your bill goes towards distributing water to all of the homes, schools and businesses across our service area.

Operating costs 22%
Everyday operations like 24/7 emergency repairs, customer service support and maintaining local waterways, parks and green spaces.
