Charges explained

On 1 July 2021, Greater Western Water became the new water corporation for Melbourne's CBD and western region. Greater Western Water includes the areas previously serviced by Western Water and City West Water.

As a state-owned water distributor and retailer, the prices we charge are regulated by Victoria’s Essential Services Commission (ESC). Greater Western Water is maintaining and honouring the existing price determinations approved by the ESC. This includes, both:

  • 2018 City West Water Determination
  • 2020 Western Water Determination.

For more information on these price determinations, please visit the Essential Services Commission website.

As Greater Western Water, we want all customers to experience the same level of service at a fair price

As part of our integration, we successfully applied to the Essential Services Commission to adjust our prices over the next two financial years (2021-2023). We consulted our customers on the proposed changes in March 2021 and they were approved by the Essential Services Commission in June 2021.

As a result of these changes, average water bills for households will be slightly lower than in 2020-21 and will increase at a rate lower than inflation for businesses. Our 2021-22 charges mean that Greater Western Water residential water bills remain some of the lowest average bills in any capital city in Australia.

Where does your money go?

The ESC’s Price Determination for City West Water sets out our prices from 1 July 2018 and the process we use to update our prices annually to 30 June 2023. The 2020-21 approved pricing begins from 1 July 2020.
We are committed to providing our customers with safe and reliable water and sewerage services at an affordable cost. When you pay your water bill, the money contributes to:

  • Supply, treatment and transfer of billions of litres of water, including water from the Victorian Desalination Plant
  • Collection, treatment, reuse, and disposal of billions of litres of sewerage and trade waste
  • Delivery and maintenance of thousands of kilometres of local water and sewer pipes
  • Information technology and phone system operations
  • Customer services and community programs
  • Licence fees, income tax and Environmental Contributions

Other government charges

How your bill is calculated?

Water Charges

Our water tariff has two components - a network charge and a water usage charge.

Water Network charge

The water network charge is a quarterly fixed charge that contributes to the maintenance of the water supply network, including our water mains, service tanks, water meters and Melbourne Water's water mains, aqueducts, treatment plants and reservoirs.

Water Usage charge

In addition to contributing to the above, the water usage charges also cover the actual cost of water that is provided to the customer.

The amount of water you are charged for using is calculated from water meter readings taken approximately once every 90 days. The amount of water recorded between readings is divided by the number of days in the reading period to calculate how much water is used every day.

Sewerage Charges

Much like the water tariffs, our sewerage tariffs have two components - a fixed sewerage network charge and a volumetric sewage disposal charge.

Sewerage Network charge

The Sewerage Network charge helps us maintain the sewerage network including our sewer mains and pumping stations and Melbourne Water's trunk sewer mains and the Western Treatment Plant.

Sewage Disposal

The sewage disposal charge is for the waste water (sewage) you discharge to the sewer, including water that goes down any inside drains, sinks, toilets and any other drains that connect to the sewer.

We estimate the volume of sewage you discharge to the sewer based on the amount of water recorded by your water meter.

For residential customers, your sewage disposal estimate depends on your type of residence (house or unit) and what season we are in.

For non-residential customers, the sewage disposal estimate is set at 90% and this does not fluctuate with the season.

For more details refer to Pricing handbook which describes the estimation methodology and how they are applied.

Fire Service Charges

Greater Western Water provides some customer sites with private fire service connections to our water network, to deliver water in the event of a fire. In response to changes in our responsibilities under the Water Regulations 2014, From 1 July 2019 we are introducing a private fire service charge that will cover the cost of operation and maintenance of the water network and fire service connection to allow for high-pressure water in the case of a fire. For more information visit our Fire services page.
 

Other Authority Charges

We collect certain charges on behalf of other Victorian State Government Agencies including the Parks Victoria Parks Charge and the Melbourne Water Waterways and Drainage Charge. Details of why and where these charges go are below.

Parks Victoria Parks Charge

We collect an annual Parks Charge on behalf of the Department of Environment, Land, Water and Planning. This charge helps fund the purchase, development and maintenance of Melbourne's major parks, gardens and waterways. This amount is usually charged during the July-September quarter and may be why your account, for that period, seems higher than normal.

The Parks Charge for each property in 2021-22 will be the greater of the minimum fee of $80.20 and a fee based on the property's 'net annual value' or 'NAV', calculated at 0.478cents per dollar of NAV per year.

Visit Parks Victoria for more information about the Parks Charge.

Melbourne Water Waterways and Drainage Charge

We collect a Waterways and Drainage Charge on behalf of Melbourne Water. This charge contributes to the management of waterways, drainage assets and floodplains in our region.

For more information about the charge and Melbourne Water's services and projects visit Melbourne Water's website.
