Great Wyrley Water Hardness & Quality Report (2026)

South Staffordshire Water supplies Great Wyrley, a village in the Cannock Chase district of Staffordshire. The town's water is drawn from a combination of groundwater from the Permo-Triassic Sherwood Sandstone aquifer of the South Staffordshire plateau and surface water from Blithfield Reservoir on the River Blithe, treated at Seedy Mill Water Treatment Works before distribution across the South Staffordshire supply area. At 162 mg/L (11.4°Clark), Great Wyrley's water is moderately hard — a level reflecting the moderate mineralisation of the Triassic sandstone aquifer blended with reservoir supply.

The Sherwood Sandstone formation underlies much of the South Staffordshire plateau and Cannock Chase area, forming a major regional aquifer supplying much of South Staffordshire Water's groundwater needs. Although predominantly quartz-dominated sandstone, the formation contains calcium carbonate in interstitial cements and minor carbonate beds, yielding groundwater with moderate hardness. Blithfield Reservoir, set within the rural Staffordshire countryside, collects water from mixed sedimentary catchments with a modest mineral contribution, further moderating the overall supply hardness.

At 162 mg/L, limescale is a noticeable but manageable domestic concern in Great Wyrley. Kettles benefit from descaling every four to six weeks to maintain heating efficiency. The combi-boiler should be fitted with a scale inhibitor and serviced annually. Washing-up liquid works well at normal quantities with only slight reduction in lather compared to soft-water areas. Taps and shower heads develop moderate limescale deposits over a few weeks; a monthly wipe with white vinegar or a proprietary descaling product keeps fittings in good condition and prevents hard-water staining from building up on surfaces and fixture seals.
