Pricing Simulators

Understanding your 2022/23 GMW Water Accounts

The Essential Services Commission (ESC) has now provided its final determination on Goulburn Murray Water (GMW) Pricing Submission 2020-24.

More information on our 2020-24 Price Submission can be found here.

Before you start

The simulator asks you to enter information from your 2021/22 Fixed Water Charges account (this account was issued in July 2021) and/or your Consumptive Water Charges account (renamed Variable Charges Account - for Irrigation Area, Pumped Districts and some Water District customers) which are issued at the end of the season.

What if I don't have a copy of my account?

If you would like a replacement copy of an account that has already been issued, contact your local GMW office or phone 1800 013 357 (Monday to Friday between 8.00am and 4.45pm) and a replacement copy can be provided free of charge.

Alternatively, roll over the help icons in each simulator and they will describe the information you need to enter into the field.

Pricing Simulator


The pricing simulator is designed to provide an indicative guide to pricing comparisons between the 2021/22 and 2022/23 seasons.

While the pricing simulator is designed to give you an indication of 2022/23 prices that will apply to your combination of services, it does not represent or display all the services that GMW offers and cannot be relied upon to provide a definitive cost calculation in each case. Every GMW customer has a different combination of services and therefore individual circumstances will vary and must be taken into account.
