These prices were reviewed through a public process, where the Essential Services Commission:

  • completed extensive analysis of Melbourne Water’s 2016 Water Plan, which sets out the expected costs to deliver planned capital works programs, service standards and forecast volumes for each prescribed service

  • reviewed capital expenditure, operating expenditure and forecast demand

  • consulted with stakeholders, including a review of submissions made by interested parties

The 2016 Water Price Review covers a five year regulatory period from 1 July 2016 to 30 June 2021. The prices set through the review reflect the efficient cost of providing waste water services.
