Maylands Water Hardness & Quality Report (2026)

Water Corporation provides water to Maylands, a suburb within the City of Bayswater in the Perth metropolitan area of Western Australia. The supply originates from a diverse network, drawing from surface water sources like Mundaring Weir, Wungong, Serpentine, and Wellington dams, supplemented by desalinated water from the Perth Seawater Desalination Plant. Groundwater from the Gnangara and Jandakot Mound aquifers also contributes significantly to the mix. Water undergoes treatment at facilities such as Wanneroo and Harrisdale, employing advanced methods like filtration, disinfection, chloramination, and fluoridation as part of the integrated Perth network.

The water's journey begins in the Perth Basin, where it interacts with limestone and sand aquifers. This geological setting is key to the water's character, as the dissolution of limestone naturally leaches minerals like calcium and magnesium, resulting in a hard water profile. While surface water from the Darling Range catchments, fed by rivers like the Helena and Avon, offers a less mineral-rich source, the overall blend, even with desalinated water, tends to retain hardness influenced by the dominant limestone geology.

Homeowners in Maylands will notice the effects of very hard water, with limescale accumulating in appliances like kettles, showerheads, and hot water systems, potentially shortening their lifespan and reducing efficiency. Detergents may not lather as effectively in washing machines, leading to stiffer fabrics, and plumbing can experience gradual encrustation. To combat this, regular descaling with vinegar or installing a water softener is often recommended. Water Corporation assures residents that while the water is hard, it meets all Australian Drinking Water Guidelines and is safe for consumption.
