Fitzroy North Water Hardness & Quality Report (2026)

Greater Western Water supplies Fitzroy North through its Richmond distribution network, drawing water from a mix of sources. These include surface reservoirs like Winneke Reservoir, Sugarloaf Reservoir, and Toorourrong Reservoir, all situated within the Yarra catchment. Supplementary groundwater from the Maribyrnong Aquifer also contributes to the supply. Major treatment facilities, such as the Winneke Water Treatment Plant, employ processes like coagulation, filtration, and disinfection using chloramine, alongside fluoridation, to ensure the water meets stringent safety standards under Victoria's Safe Drinking Water Act 2003.

The region's water originates from a complex geological landscape. The Yarra River watershed itself is largely composed of Ordovician turbidites and Cambrian greenstones, capped in places by Miocene basalts from the Newer Volcanics Province. Overlying these older formations in the Melbourne Trough are Silurian siltstones and sandstones, along with Quaternary alluvial sediments and Pleistocene basalt flows. Crucially, the absence of significant carbonate rock formations, such as limestone or dolomite, means the water has limited contact with mineral-rich deposits. This geological makeup, combined with rainwater-dominated recharge and short flow paths through fractured bedrock and volcanic soils, results in water that is naturally soft and low in dissolved minerals like calcium and magnesium.

This soft water profile means homeowners in Fitzroy North will likely notice fewer issues with limescale buildup in appliances such as kettles, water heaters, and dishwashers, potentially extending their lifespan. Laundry detergents and soaps tend to foam more readily, allowing for reduced usage and gentler effects on skin and hair. While a water softener isn't typically recommended due to the naturally soft nature of the supply, it's advisable to monitor copper plumbing for potential corrosion if the water's pH happens to trend low, though corrosion inhibitors are added to mitigate this. Residents can generally enjoy spot-free glassware from dishwashers with careful use of rinse aids and appreciate the efficiency of cleaning products without the need for excessive amounts.
