Ringwood East Water Hardness & Quality Report (2026)

Ringwood East's drinking water is supplied by Yarra Valley Water as water retailer, with bulk supply from Melbourne Water via predominantly direct Maroondah Reservoir catchment supply for the Maroondah City Council LGA inner eastern Melbourne distribution in Victoria. Water hardness in Ringwood East is measured at 14.5 mg/L — classified as extremely soft — well below the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Ringwood East, in the Maroondah City LGA — an established inner eastern Melbourne suburb adjacent to Ringwood and Bayswater, known for the Ringwood East railway station community, the Ringwood Lake Park and wetlands reserve, the established Maroondah residential character of the Ringwood East-Bayswater corridor, and the inner eastern Melbourne community adjacent to the Dandenong Ranges foothills — receives an extremely soft supply from the direct Maroondah Reservoir catchment routing, among the softest in metropolitan Melbourne.

Ringwood East's extremely soft supply reflects the predominantly direct Maroondah Reservoir catchment supply routing at the inner eastern Maroondah City Yarra Valley Water sub-zone. The Maroondah Reservoir (Maroondah Dam) is on the Watts River in the Yarra Ranges, draining the Yarra Ranges National Park — protected Devonian granite, dolerite, and metamorphic terrain contributing essentially zero dissolved minerals. At 14.5 mg/L and TDS 24.2 mg/L, Ringwood East's extremely soft supply is among the very softest in metropolitan Melbourne, consistent with Sandy Bay TAS (14.5 mg/L), and contrasts dramatically with the harder Bayswater Maroondah sub-zone (93.5 mg/L) in the adjacent Maroondah LGA — confirming very different distribution routings across the inner eastern Melbourne Yarra Valley Water sub-zones.

Ringwood East residents accumulate virtually no limescale — scale on taps and kettles is negligible. Hot water systems experience minimal scale build-up. The very low lead reading (0.001 mg/L) is excellent. Yarra Valley Water provides water quality information at yvw.com.au, with all ADWG health standards consistently met. Ringwood East's Maroondah City inner eastern residential community and the Ringwood Lake Park corridor benefit from this exceptionally soft supply meeting all ADWG standards.
