Price Submission: Final Determination

Please note: the information on this page relates to properties previously serviced by City West Water only. Greater Western Water is currently developing its pricing submission for the period commending 1 July 2023. Read more.

The Essential Services Commission (ESC) has made its determination on our Price Submission. This determination on our Price Submission covers our service standards, prices and tariffs from 1 July 2018 to 30 June 2023.

The ESC, the independent economic regulator of the water sector in Victoria, assessed our submission against a new performance model that places a high importance on customer engagement and value for money.

Based on extensive customer engagement we developed a Pricing Submission that delivers the following outcomes:

  • Services to homes and businesses are safe, reliable and efficiently delivered
  • Customer service is accessible and enquiries are promptly resolved
  • Billing and payment options are efficient and convenient
  • Customers in hardship are supported
  • The whole of the water cycle is managed in an environmentally sustainable way
  • We are a valued partner in servicing a growing Melbourne.

Who we consulted

Our Price Submission was developed based on asking customers what matters to them and how we can better meet their expectations.To do this we ran a wide-reaching engagement program that was open to all of our customers.

Our 2018 Pricing Submission builds on the efficiencies we’ve achieved over the past five years, so we could deliver real price reductions for all of our customers.

Supporting customers in hardship

We aim to support customers experiencing hardship or the impacts of family violence. We will do all we can to ensure they are aware of and can access the support services available.

We will also take the following actions:

  • Maintain current hardship processes including referrals, payment plans and water efficiency assistance programs including Water Assist
  • Continue to implement programs to support customers or employees affected by family violence, including specialised frontline training for staff
  • For customers with a verified and fixed leak, charge the wholesale cost of water (rather than the normal cost) for the estimated volume of water lost due to the leak, reducing the impact on bills.
