What Makes Keilor East's Water Unique?
Local geology and source profile
Keilor East's drinking water is supplied by City West Water as water retailer, with bulk supply from Melbourne Water drawn predominantly from the Thomson Reservoir and Upper Yarra Reservoir catchments in the Yarra Ranges, Victoria. Water hardness in Keilor East is measured at 13.5 mg/L — classified as very soft — far below the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Keilor East, in the Moonee Valley LGA — a low-density outer northern Melbourne suburb at the Maribyrnong River escarpment, with extensive market garden and golf course heritage, adjacent to the Calder Freeway corridor — receives near-pure Yarra Ranges reservoir supply, notably softer than Moonee Ponds (29 mg/L) and Ascot Vale (23.5 mg/L) in the same Moonee Valley LGA, confirming that the outer northern edge of the Moonee Valley distribution receives the purest, softest supply in the LGA.
Keilor East's very soft supply reflects a distribution sub-zone receiving near-pure direct Thomson and Upper Yarra reservoir supply with essentially negligible Winneke Water Treatment Plant contribution. The Thomson and Upper Yarra storages drain across Devonian granite and rhyodacite — highly resistant igneous terrain contributing negligible dissolved minerals — delivering near-pure Yarra Ranges rainwater at 13.5 mg/L and TDS 22.4 mg/L to this outer northern Moonee Valley residential enclave. The Keilor East supply is among the softest recorded in the City West Water distribution network.
Keilor East residents experience essentially no limescale on taps, in kettles, and around shower fittings. Hot water systems accumulate minimal scale over their service life. The very low lead reading (0.001 mg/L) confirms outstanding supply quality. City West Water provides water quality information at citywestwater.com.au, with all ADWG health standards consistently met. The near-pure soft supply is a natural benefit for Keilor East's outer northern Moonee Valley community at the Maribyrnong River corridor and the nearby Essendon Airport precinct.
Geology & Source: Supplied by City West Water (water retailer) and Melbourne Water (wholesale) predominantly from the Thomson Reservoir and Upper Yarra catchment systems — the Keilor East Moonee Valley outer northern supply carries very soft water at 13.5 mg/L with very low TDS of 22.4 mg/L, reflecting near-pure direct Yarra Ranges reservoir supply at this outer northern Moonee Valley Melbourne distribution sub-zone with negligible Winneke WTP contribution.
