Fitzroy Water Hardness & Quality Report (2026)

Yarra Valley Water supplies Fitzroy and over 3 million residents across 81 local councils in metropolitan Melbourne, Victoria, Australia. The water comes primarily from bulk treated surface water drawn from 11 storages, including Thomson Reservoir, Sugarloaf Reservoir, and Cardinia Reservoir. This water travels through Melbourne Water's closed conduit system to treatment plants like Winneke, Ovals, and Wollert. Advanced processes such as dissolved air flotation, ozonation, filtration, chloramination, and fluoridation are employed before the water is distributed.

The Yarra catchment, spanning 3,867 km², contains Paleozoic sandstones and mudstones, intruded by Devonian granites. Surficial deposits include ferruginous gravels and peaty soils. This geology, particularly the non-calcareous bedrock and podzolic soil profile, results in naturally soft water with low dissolved solids. These characteristics contribute to the soft water quality, as the rocks do not readily release minerals like calcium and magnesium.

Because the water is soft, Fitzroy residents will notice minimal limescale buildup on appliances like kettles and washing machines, which helps extend their lifespan. You'll also find that soap lathers easily, potentially reducing detergent use by 30-50%. While this soft water typically doesn't require a water softener, it can pose a minor corrosion risk to copper plumbing. Yarra Valley Water manages this by adjusting the pH to between 7.5 and 8.5 and adding orthophosphate to protect pipes. No specific descaling tips are needed for household items, and the focus remains on general water quality parameters like legionella prevention in stagnant fixtures.
