Carnoustie Water Hardness & Quality Report (2026)

Scottish Water supplies Carnoustie, the coastal Angus town with one of the world's most celebrated and feared golf links — host of The Open Championship on multiple occasions including the famous 1999 Open when Jean van de Velde's collapse at the 72nd hole became one of golf's most dramatic moments — from Lintrathen Reservoir in the Angus Glens near Alyth, treated at Forfar Water Treatment Works. At 64 mg/L (4.5°Clark), Carnoustie's water is soft — consistent with the Old Red Sandstone, Devonian conglomerate, and Precambrian metamorphic upland catchments of the Angus Glens that contribute very little calcium to the Lintrathen reservoir supply.

Carnoustie lies on the Angus coast where Scottish Water delivers supply from Lintrathen Reservoir in the Angus Glens — a catchment on Old Red Sandstone Devonian upland and Precambrian Dalradian metamorphic rock that yields low-mineralisation soft surface water. Lintrathen supply produces 64 mg/L with TDS 137.6 mg/L at Carnoustie — soft water consistent with the Angus coastal tier from Arbroath (68.5 mg/L) and Montrose (64 mg/L) in the same Scottish Water Angus distribution zone.

At 64 mg/L, limescale is a minimal household concern in Carnoustie. Kettle descaling once every two to three months is all that is typically required. The combi-boiler has minimal scaling risk. Washing-up liquid lathers easily. Taps and shower heads accumulate very little limescale; a quarterly wipe keeps fixtures clean. The soft Angus upland supply at Carnoustie is far removed from the punishing challenges of its links course — on the golf course, every subtle break of the green matters; in the kitchen, the kettle at Carnoustie can be left largely to its own devices.
