Bulk sewerage

​We charge Melbourne’s three metropolitan retail water businesses to remove, treat and dispose of the sewage and trade waste we collect from them.

Our bulk sewerage customers are:

  • City West Water
  • South East Water
  • Yarra Valley Water

Bulk sewerage charges comprise three components:

  • fixed monthly availability price
  • variable price relating to treatment and transfer
  • variable load price relating to the cost of treatment of each contaminant for safe disposal

Prices from 1 July 2020 to 30 June 2021

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 wastewater services.
