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 2015
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.
