City West Water is responsible for supplying drinking water to customers throughout Melbourne’s CBD and inner and western suburbs.
As a Victorian Government owned company, City West Water is subject to strict government regulation and close scrutiny in our management of water quality. All 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 340 properties throughout our licence area. Each year, over 2,000 microbiological and 300 physical/chemical samples are collected and tested on our behalf by an independent, specialised laboratory, certified 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 and accessible from our website, at our office, or by calling us on 13 1691. Reference to this document shows that the water quality more than meets required standards as well as health related Australian drinking water quality guidelines.
