Maylands Water Hardness & Quality Report (2026)

Maylands' drinking water is supplied by the Water Corporation via the Integrated Water Supply Scheme (IWSS), incorporating a balanced blend of Gnangara Mound groundwater, desalinated supply, and Mundaring Weir (Helena River/Darling Range) surface water for the City of Bayswater LGA inner northern Perth distribution in Western Australia. Water hardness in Maylands is measured at 137.5 mg/L — classified as moderately hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Maylands — a cosmopolitan inner northern Perth suburb on the south bank of the Swan River, known for the Maylands Waterland, the Peninsula shopping village on Eighth Avenue, the Maylands vintage retail strip, and the popular inner-city community of creative professionals and young families — receives moderately hard supply, slightly harder than adjacent Bayswater (111 mg/L) in the same City of Bayswater LGA, reflecting the IWSS blend variation across the inner northern Perth distribution.

Maylands' moderately hard supply reflects the IWSS blend incorporating a moderate Tamala Limestone groundwater fraction combined with desalinated supply and Mundaring Weir surface catchment contributions. The Mundaring Weir collects water from the Darling Range — Precambrian granite and laterite terrain contributing soft, low-mineral runoff — moderating the hard Gnangara Mound character. The Maylands inner northern Bayswater distribution at 137.5 mg/L and TDS 326 mg/L is slightly harder than Bayswater (111 mg/L), reflecting a proportionally higher groundwater fraction in this southerly inner Bayswater sub-zone routing.

Maylands residents face moderate limescale build-up on taps and in kettles — descaling every two to three weeks is typical. Hot water systems benefit from periodic inspection. The very low lead reading (0.002 mg/L) is excellent. Solar hot water systems in WA's climate benefit from annual servicing. Under WA water restrictions, garden irrigation is limited. The Water Corporation provides water quality information at watercorporation.com.au, with all ADWG health standards met. Maylands' vibrant Peninsula village and Swan River lifestyle community benefits from a safe supply.
