Overview
We are reviewing the prices to apply for Coliban Water customers from 1 July 2023.
Coliban Water submitted its proposed prices on 30 September 2022. We provided guidance for its price submission in October 2021 and the business has been engaging with customers in the months since.
We are assessing the proposal against a legal framework established by the Victorian Government and set out in the Water Industry Regulatory Order (PDF), and the commission’s PREMO pricing framework.
PREMO includes incentives for Victoria's water businesses to put forward their best offer to customers and deliver the outcomes its customers value most.
Following consultation, we issue a determination that sets the maximum prices that Coliban Water may charge customers.
We are seeking feedback from customers and stakeholders at multiple points throughout the price review process to inform our decision-making process.
Feedback on Coliban Water's proposals
We consulted on Coliban Water's price submission until 1 December 2022. Submissions can be viewed in the resources tab of this page.
We will undertake further consultation upon release of our draft decision.
