Kurunjang Water Hardness & Quality Report (2026)

Kurunjang's drinking water is supplied by City West Water as water retailer, with bulk supply from Melbourne Water incorporating a low-to-moderate Winneke Water Treatment Plant contribution for the Melton Shire Council LGA outer western Melbourne distribution in Victoria. Water hardness in Kurunjang is measured at 65.5 mg/L — classified as slightly hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Kurunjang, in the Melton Shire LGA — a large master-planned residential community in the outer western Melbourne Melton growth corridor adjacent to Melton town centre, known for the Kurunjang Woodlands reserve and parklands, the Melton South-Kurunjang shared growth estate residential precinct, and the rapidly developing outer western Melbourne community of the Melton Shire growth area — receives slightly elevated supply in the same distribution sub-zone as the adjacent Brookfield suburb (65.5 mg/L), reflecting the consistent City West Water outer western Melton distribution character.

Kurunjang's slightly elevated hardness reflects a low-to-moderate Winneke Water Treatment Plant contribution at the outer western Melton Shire City West Water distribution sub-zone, identical to the adjacent Brookfield sub-zone (65.5 mg/L, TDS 132.4 mg/L) in the same Melton LGA City West Water distribution. The Winneke WTP draws from the Yarra River at Yering Gorge traversing Devonian basalt terrain — contributing moderate calcium. At 65.5 mg/L, Kurunjang is slightly softer than Melton South (77.5 mg/L) in the same Melton LGA, reflecting the consistent outer western Melton distribution character of the City West Water Melton supply corridor.

Kurunjang residents can expect occasional light limescale on taps and in kettles — descaling every two to three months is typically adequate. Hot water systems benefit from periodic inspection. The low lead reading (0.003 mg/L) is good. City West Water provides water quality information at citywestwater.com.au, with all ADWG health standards consistently met. Kurunjang's outer western Melbourne Melton growth estate community benefits from a safe supply meeting all ADWG standards.
