Inverurie Water Hardness & Quality Report (2026)

Scottish Water supplies Inverurie, the thriving market town and railway junction in Garioch in Aberdeenshire, at the confluence of the River Don and River Urie north-west of Aberdeen, from the upper River Don catchment in the Grampian Mountains and from local Aberdeenshire water sources, treated at Inverurie Water Treatment Works. At 67.5 mg/L (4.7°Clark), Inverurie's water is soft, reflecting the predominantly Dalradian metamorphic and Grampian granite geology that forms the upper Don catchment above Strathdon.

The upper River Don rises in the Grampian Mountains above Corgarff and flows through Strathdon — a landscape dominated by ancient Dalradian Supergroup metamorphic rocks (quartzite, pelitic schist, psammite) and large masses of Caledonian granite (the Cairngorm–Lochnagar granites). These silica-rich, acid-resistant rocks yield little dissolved calcium to the River Don catchment. Minor calc-schist and limestone lenses within the Dalradian sequence contribute a modest calcium increment, producing the slightly elevated TDS of 147.4 mg/L and hardness of 67.5 mg/L — soft but not as extremely soft as the purest Southern Upland or Atlantic moorland supplies.

At 67.5 mg/L, Inverurie's soft water is comfortable for domestic use. Limescale builds only slowly; descaling the kettle every two to three months is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a sensible precaution. Washing-up liquid lathers well at everyday quantities. Taps and shower heads remain relatively clean with only occasional maintenance. The soft Grampian supply is characteristic of the Aberdeenshire market towns served by the upper Don catchment, offering clean, naturally soft water typical of Scotland's ancient hard-rock mountain geology.
