St Albans Water Hardness & Quality Report (2026)

St Albans's drinking water is supplied by City West Water as water retailer, with bulk supply from Melbourne Water drawn from the Thomson Reservoir and Upper Yarra Reservoir catchments in the Yarra Ranges, Victoria. Water hardness in St Albans is measured at 68.5 mg/L — classified as slightly hard — within the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. St Albans, in Melbourne's inner west Brimbank LGA, receives Melbourne Water's Yarra Ranges supply through the western metropolitan distribution network, which serves the diverse communities of the western suburbs from Footscray to Sunshine.

St Albans's slightly elevated hardness compared to the Melbourne CBD (41.5 mg/L) reflects the characteristics of the western Melbourne distribution network. The supply originates from the same Devonian granite and rhyodacite catchments of the Yarra Ranges, but the western distribution pathway — which connects Melbourne Water's storages through the western distribution system, potentially incorporating treatment at the Western Treatment Plant corridor — produces measurably harder supply at the St Albans inner western suburban tap compared to the CBD and eastern suburbs.

St Albans residents see occasional light limescale deposits on tap fittings and in kettles — descaling every two to three months is generally adequate. Hot water systems benefit from periodic inspection but accumulate only moderate scale. The elevated lead reading (0.003 mg/L) warrants briefly running the cold tap before use in older homes, particularly in the established interwar and post-war housing stock of the St Albans heritage residential streetscapes.
