Wendouree Water Hardness & Quality Report (2026)

Central Highlands Water supplies the Wendouree area and surrounding parts of the Ballarat region in Victoria, Australia. The water comes from a mix of sources, primarily surface water drawn from the Moorabool River catchment. To ensure a reliable supply, especially during dry spells, the Wimmera-Mallee Pipeline also contributes water. Treatment is carried out at facilities like the Ballarat Water Treatment Plant, which employs standard methods such as coagulation, filtration, and disinfection to ensure the water meets the Australian Drinking Water Guidelines. Key reservoirs feeding the system include Hepburn Lagoon and White Swan Reservoir.

The region's geology plays a significant role in the water's composition. The underlying rock formations are primarily Paleozoic sandstones, mudstones, and volcanics belonging to the Lachlan Fold Belt. These are often covered by rich, basalt-derived soils. This combination means that as surface water flows through the landscape, it picks up minerals from the soil and occasional limestone outcrops. Blending water from the pipeline also influences the final mineral content, creating a supply that is moderately mineralised rather than being very soft.

Because the water is only moderately hard, you'll likely notice less scale buildup in your appliances and pipes compared to areas with very hard water. While kettles and showerheads might develop a light film over time, your dishwasher and water heater won't be as heavily affected. A simple vinegar soak is usually enough to clear any minor deposits. Most residents find a whole-house water softener isn't necessary, though some may opt for one if they have particularly sensitive skin or specific appliance needs. Central Highlands Water consistently reports that the water complies with Victoria’s drinking water regulations, with no significant issues regarding common contaminants or hardness.
