Our water supply comes from three large reservoirs – Silvan, Greenvale and Sugarloaf – that form a part of Melbourne’s overall, well established catchment and reservoir system. The result is a safe, clean and high quality drinking water supply that continues to meet the high standard for which Melbourne has been long renowned.
Water Quality Monitoring
In order to verify the high quality of the water supply, we arrange independent, day-to-day water sampling and testing at the supply points to some 460 properties throughout our licence area.
Each year, over 3,000 microbiological and 800 physical/chemical samples are collected and tested on our behalf by an independent, specialised laboratory, accredited by the National Association of Testing Authorities.
Details of the tests undertaken, together with actual test results, are presented in our Annual Drinking Water Quality Report, which is published in mid-October. Reference to this document shows that the water quality more than meets required standards, as well as health related Australian drinking water quality guidelines.
