What Makes Glenrothes's Water Unique?
Local geology and source profile
Glenrothes, the central Fife new town developed from 1948 on the Fife coalfield plain, is supplied by Scottish Water from Loch Fitty near Dunfermline and the Lochore Meadows catchment area in the Blairadam Hills of central Fife. Loch Fitty is a reservoir impounding the Fitty Burn on the Carboniferous sandstone and volcanic rock uplands of west-central Fife — the same Carboniferous geology of the Fife coalfield but in the upland catchment areas. The Bishop Hill and Blairadam Forest catchments drain Devonian and Carboniferous lavas, sandstones, and Old Red Sandstone moorland — formations that contribute very little dissolved calcium. Scottish Water treats and distributes to Glenrothes and central Fife from the Fife upland reservoir system.
Glenrothes's soft water — 61 mg/L (4.3°Clark) — reflects the Carboniferous and Devonian lava and sandstone moorland catchments of the central Fife reservoir supply. The Drinking Water Quality Regulator for Scotland classifies this supply as soft.
Limescale is very minor in Glenrothes. At 61 mg/L, limescale builds slowly — kettles need descaling every two to three months. Combi-boiler heat exchangers accumulate minimal deposits; annual servicing is routine. Showerheads and taps remain largely clear. Washing-up liquid lathers very well with the soft Fife supply. Limescale is not a significant domestic concern for Glenrothes households on the Scottish Water Fife reservoir supply.
Geology & Source: Supplied by Scottish Water from Loch Fitty and Lochore Meadows catchment in central Fife — Glenrothes's central Fife new town position draws on Scottish Water's upland reservoir supply from the Carboniferous sandstone and lava moorland of the Blairadam Hills and Bishop Hill, producing soft water at 61 mg/L (4.3°Clark).
