Wodonga Water Hardness & Quality Report (2026)

Wodonga's drinking water is supplied by North East Water, drawn from the Murray River system via Hume Reservoir — the large storage on the upper Murray River — and local stream sources in north-east Victoria near the NSW border. Water hardness in Wodonga is measured at 105.5 mg/L — classified as moderately hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. The Albury-Wodonga cross-border region shares the upper Murray supply corridor, with North East Water managing the Victorian side of this integrated regional supply system.

Wodonga's moderate hardness reflects the geology of the upper Murray catchment. The Hume Reservoir catchment in the Australian Alps drains through Silurian–Devonian granite and metamorphic schist terrain — which itself produces relatively soft water — but the extended Murray floodplain traversal and alluvial mixing through the Riverina and Alpine piedmont zone contributes modest calcium and magnesium loading to the stored supply. The Murray River at Hume Reservoir carries a moderate dissolved mineral load from its alpine headwaters mixed with floodplain alluvial contact in the upper valley.

Wodonga residents can expect moderate limescale build-up on taps and in kettles — descaling every two to three months is typical. Hot water systems benefit from periodic inspection to check for scale. The elevated lead reading (0.004 mg/L) warrants running the cold tap briefly before use in older established homes in Wodonga's historic residential areas adjacent to the Murray corridor. North East Water provides water quality information at new.com.au, with all ADWG health standards consistently met throughout the Albury-Wodonga distribution network.
