What Makes North Melbourne's Water Unique?
Local geology and source profile
North Melbourne's drinking water is supplied by City West Water as water retailer, with bulk supply from Melbourne Water drawn predominantly from the Thomson Reservoir and Upper Yarra Reservoir catchments in the Yarra Ranges, Victoria. Water hardness in North Melbourne is measured at 48.5 mg/L — classified as soft — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. North Melbourne, in the City of Melbourne LGA — the rapidly transforming inner north suburb adjacent to the Melbourne CBD, home to North Melbourne Football Club's home ground, the Flemington Road heritage precinct, the Queen Victoria Market, and significant apartment development — receives predominantly soft Yarra Ranges reservoir supply, slightly harder than the adjacent Carlton (18 mg/L) sub-zone in the same City of Melbourne LGA.
North Melbourne's soft supply reflects a distribution sub-zone receiving predominantly direct Thomson and Upper Yarra reservoir supply with a moderate Winneke Water Treatment Plant contribution. The Thomson and Upper Yarra storages drain across Devonian granite and rhyodacite — highly resistant igneous terrain contributing negligible dissolved minerals. The North Melbourne inner northern City of Melbourne distribution sub-zone at 48.5 mg/L and TDS 92.3 mg/L reflects an intermediate position in the City of Melbourne LGA supply spectrum — softer than the outer inner city zones receiving more Winneke WTP blending but harder than the near-pure Carlton and Docklands sub-zones.
North Melbourne residents enjoy very low limescale accumulation on taps, in kettles, and around shower fittings — descaling is an occasional rather than regular task. Hot water systems accumulate minimal scale. The elevated lead reading (0.003 mg/L) warrants briefly running the cold tap before use in North Melbourne's many heritage Victorian-era terrace homes and newer apartment buildings. City West Water provides water quality information at citywestwater.com.au, with all ADWG health standards consistently met.
Geology & Source: Supplied by City West Water (water retailer) and Melbourne Water (wholesale) predominantly from the Thomson Reservoir and Upper Yarra catchment systems — the North Melbourne City of Melbourne inner north supply carries soft water at 48.5 mg/L, reflecting a predominantly direct Yarra Ranges reservoir supply blend with a moderate Winneke WTP fraction at the City of Melbourne inner north distribution sub-zone.
