Australind Water Hardness & Quality Report (2026)

Water Corporation provides drinking water to Australind and surrounding localities like Eaton and Picton in Western Australia's South West region. The primary source is groundwater drawn from the Leederville aquifer through bores, with the Yarragadee aquifer serving as a backup. Water is treated at the Australind water treatment plant, where processes include filtration to remove iron, manganese, and turbidity, pH adjustment, and chlorination for disinfection. This system supplies the Shire of Harvey area, relying entirely on these underground sources without any surface water inputs.

The groundwater originates from confined aquifers within the Leederville and Yarragadee formations. These geological layers, dating back to the Cretaceous period, are composed of permeable sandstones and limestones. As water moves through fractures and porous rock, it dissolves calcium and magnesium carbonates, leading to a naturally hard water supply. The raw water also contains elevated levels of iron, manganese, turbidity, colour, chloride, and sodium due to its interaction with the mineral-rich subterranean environment.

Homeowners in Australind often notice scale buildup in appliances like kettles, hot water systems, and dishwashers, which can also leave spots on glassware and reduce soap's lathering ability. Monthly descaling with vinegar and regular pressure valve releases on hot water systems are common maintenance tasks. Selecting dishwasher models designed for hard water conditions can be beneficial. For those experiencing significant issues, installing a whole-house water softener is recommended to protect plumbing and extend appliance lifespan. Water Corporation tests confirm that despite naturally occurring challenges in the raw supply, the treated water consistently meets all health and aesthetic guidelines set by the Australian Drinking Water Guidelines.
