Cheadle Water Hardness & Quality Report (2026)

Severn Trent Water supplies Cheadle, the Staffordshire market town on the edge of the Peak District and the Churnet Valley — a quiet agricultural market town southeast of Stoke-on-Trent, at the foot of the Weaver Hills with its historic bull-running traditions and proximity to the picturesque Churnet Valley Railway and the gardens of Alton Towers — from Derwent Valley Reservoirs (Howden, Derwent, and Ladybower in the Peak District) blended with Permo-Triassic Sherwood Sandstone groundwater in the east Staffordshire distribution zone, treated at Bamford Water Treatment Works. At 161.5 mg/L (11.3°Clark), Cheadle's water is hard — reflecting the Triassic Sandstone and moderate Carboniferous Coal Measures groundwater contribution in the east Staffordshire supply blend.

Cheadle sits on the boundary of the Potteries Coalfield (Carboniferous Coal Measures) and the fringe of the Peak District Carboniferous Limestone. Severn Trent supplies from Derwent Valley reservoirs (soft) blended with a Triassic Sandstone groundwater fraction from the east Staffordshire plain, producing 161.5 mg/L with TDS 423.4 mg/L — hard water with a somewhat elevated TDS/hardness ratio (2.62) indicating minor sulphate from the Triassic Keuper Marl and Coal Measures beds in the east Staffordshire supply zone.

At 161.5 mg/L, limescale is a consistent household challenge in Cheadle. Kettles should be descaled monthly. The combi-boiler benefits from a fitted scale inhibitor and annual professional servicing. Washing-up liquid requires more product per wash. Taps and shower heads develop visible white limescale deposits within one to two weeks; a fortnightly wipe with white vinegar or a proprietary descaling product keeps fittings clean. The hard supply in Cheadle is characteristic of the east Staffordshire distribution zone — a blend of soft Peak District reservoir water and mineralised Triassic Sandstone groundwater characteristic of the southern Pennine fringe.
