Meikle Earnock Water Hardness & Quality Report (2026)

Meikle Earnock, a suburb of Hamilton in South Lanarkshire, is supplied by Scottish Water from Daer Reservoir in the upper Clyde headwaters and Camps Reservoir in the Southern Uplands, distributed through the south Lanarkshire supply network. Daer Reservoir sits in the Southern Uplands on the Leadhills moorland — a high, remote watershed draining ancient Silurian greywacke, greywacke schist, and Ordovician rocks of the Southern Uplands. These very old, insoluble marine sedimentary and metamorphic rocks yield essentially calcium-free runoff. Camps Reservoir in the Culter Fell range adds further very soft Southern Uplands catchment supply. Scottish Water treats and distributes this Clyde headwater supply northward to Hamilton and the south Lanarkshire towns.

Meikle Earnock's very soft water — 46 mg/L (3.2°Clark) — reflects the Southern Uplands catchment chemistry of Daer and Camps reservoir supply. The Silurian greywacke moorland of the Leadhills and Culter Fell country is among the most insoluble catchment geology in Scotland. At this low hardness, water is naturally slightly acidic and has very low total dissolved solids. The Drinking Water Quality Regulator for Scotland classifies this supply as soft.

Limescale is virtually absent in Meikle Earnock homes. At 46 mg/L, limescale forms minimally and kettles need descaling only every two to three months at most. Combi-boiler heat exchangers accumulate negligible deposits; annual servicing is routine. Showerheads and taps remain largely clear. Washing-up liquid lathers excellently. However, very soft slightly acidic water can be mildly corrosive to copper plumbing — older South Lanarkshire properties with original copper pipework should be checked periodically. Scottish Water treats the supply to maintain optimal pH above 7 to minimise any such risk.
