What Makes Middleton's Water Unique?
Local geology and source profile
Middleton, in the Metropolitan Borough of Rochdale in north-east Greater Manchester, is supplied by United Utilities from Pennine upland reservoirs in the Rochdale and south Pennine moorland catchments — including Piethorne Reservoir, Ogden Reservoir, and the Rochdale dale reservoirs impounding moorland streams from Carboniferous Millstone Grit moorland above Rochdale. These Pennine gritstone moorland reservoirs collect soft water from the peat and sandstone moorland of the South Pennines. United Utilities distributes through the north-east Manchester network, blending with the wider Greater Manchester grid to produce a moderately soft supply for Middleton. The Rochdale valley Pennine reservoirs are somewhat softer than the Yorkshire Water supply zones because they draw from a higher proportion of pure Millstone Grit moorland catchment.
Middleton's hardness of 117 mg/L (8.2°Clark) reflects the blend of soft Pennine reservoir supply and United Utilities distribution network contributions in the Rochdale/north-east Manchester zone. This is softer than Huyton (165 mg/L) and Macclesfield (165 mg/L) which receive harder Cheshire/Mersey catchment blending. The Drinking Water Inspectorate (DWI) classifies this supply as moderately soft.
Limescale is a moderate concern in Middleton. At 117 mg/L, limescale forms gradually and kettles need descaling every one to two months. Combi-boiler heat exchangers accumulate modest deposits; annual servicing is sensible. Showerheads and taps develop light deposits. Washing-up liquid lathers reasonably well. A monthly Calgon tablet in the washing machine and a regular kettle descale is adequate limescale management for most Middleton households.
Geology & Source: Supplied by United Utilities from Pennine upland reservoirs including Piethorne and Ogden in the Rochdale moors — Middleton's north-east Greater Manchester position on the Pennine fringe draws on United Utilities' blended local Pennine moorland reservoir and network supply, producing moderately soft water at 117 mg/L (8.2°Clark).
