Wombourne Water Hardness & Quality Report (2026)

South Staffordshire Water supplies Wombourne, a large village south-west of Wolverhampton on the Staffordshire and Worcestershire Canal — one of south Staffordshire's largest commuter settlements, set among the Brindley Hills country park — from Permo-Triassic Sandstone (Sherwood Sandstone) groundwater and the Elan Valley aqueduct blend in the south Staffordshire supply zone, treated at Blithbury Water Treatment Works near Rugeley. At 225.5 mg/L (15.8°Clark) and a TDS of 663.5 mg/L, Wombourne's water is hard — with a notably high TDS/hardness ratio indicating elevated non-carbonate minerals, likely sulphate from Triassic Keuper Marl (Mercia Mudstone) gypsum dissolution beneath south Staffordshire.

Wombourne lies in the south Staffordshire supply zone where the Permo-Triassic Sandstone (New Red Sandstone) and Mercia Mudstone (Keuper Marl) underlie the Brindley Hills fringe. South Staffordshire Water blends the soft Elan Valley Welsh aqueduct supply with hard local Triassic groundwater that carries elevated calcium, sulphate, and chloride from the Mercia Mudstone gypsum veins. The resulting 225.5 mg/L hardness with TDS 663.5 mg/L indicates significant sulphate-type hardness in addition to carbonate hardness — a Triassic Mercia Mudstone groundwater signature.

At 225.5 mg/L, limescale is a persistent household challenge in Wombourne. 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 than in softer areas. 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 and prevents staining from accumulating on surfaces in this hard south Staffordshire Triassic gypsum-influenced supply zone.
