Albany Water Hardness & Quality Report (2026)

Water Corporation serves about 15,000 residents in Albany and the surrounding Great Southern region of Western Australia. The water comes primarily from the Cape Riche and Mulka aquifers, with additional surface water drawn from the Kalgan River catchment. During times of high demand or system maintenance, water is also brought in by truck. The Albany Water Treatment Plant handles the purification process, which includes coagulation, filtration, and disinfection using chlorination. For dental health benefits, fluoridation is also part of the treatment.

The water supply originates from the Kalgan River watershed, which lies within the Warren Bioregion. Geologically, this area is characterized by the Tamala Limestone formation, a Quaternary-era calcarenite deposited by wind, as well as fractured granite aquifers. These formations contain a high concentration of calcium carbonate, and the weathered granitic soils contribute minerals through leaching. These geological factors naturally dissolve into the water, giving it a characteristically hard quality. Seasonal rainfall influences perched groundwater lenses, further increasing mineral content due to prolonged contact with the rocks.

This very hard water can lead to significant scale buildup in appliances like kettles, dishwashers, washing machines, and hot water systems, which not only reduces their efficiency but also their lifespan. Heating elements and boilers are particularly susceptible, often needing descaling every six to twelve months. To combat this, homeowners can install scale-inhibiting filters, use vinegar for appliance soaks, or choose appliances designed for low water usage. For those with scale-sensitive equipment, a water softener is highly recommended to prevent damage and prolong the life of their appliances. The water quality consistently meets the Australian Drinking Water Guidelines, with occasional minor increases in iron that are effectively treated.
