We test water quality at our major storage reservoirs once it has been through the primary treatment process. Results are used to provide a typical analysis of Melbourne's water quality, which is based on data from the previous five years.
Last update: July 2016
Our Water Quality Annual Report (previously Annual Report to the Department of Health) provides a comprehensive account of drinking water quality issues for each financial year. Yearly summaries of water quality data specific to your region are available from your local water retail company.
