Market Drayton Water Hardness & Quality Report (2026)

Severn Trent Water supplies Market Drayton, the north Shropshire market town on the River Tern — renowned as the birthplace of Robert Clive (Clive of India) and celebrated for its traditional gingerbread, still produced by a local bakery on the town's Thursday market street — from the River Tern catchment and Permo-Triassic Sandstone (Sherwood Sandstone) groundwater blend in the north Shropshire supply zone, treated at Whitchurch Water Treatment Works. At 151 mg/L (10.6°Clark), Market Drayton's water is moderately hard — consistent with the moderate calcium loading from the Permo-Triassic Sherwood Sandstone aquifer that underlies the north Shropshire plain.

Market Drayton lies on the Shropshire Plain where the Permo-Triassic Sherwood Sandstone provides the main aquifer beneath the drift-covered lowland. Severn Trent Water draws on Triassic Sandstone groundwater and Tern Valley surface supply, producing 151 mg/L with TDS 398.6 mg/L — moderately hard water with a somewhat elevated TDS/hardness ratio (2.6) suggesting a minor sulphate contribution from Mercia Mudstone (Keuper Marl) geology in the north Shropshire plain, consistent with the Severn Trent north Shropshire supply tier.

At 151 mg/L, limescale is a consistent household concern in Market Drayton. Kettles benefit from descaling every four to six weeks. The combi-boiler should be fitted with a scale inhibitor and serviced annually. Washing-up liquid requires more product per wash than in softer areas. Taps and shower heads develop moderate white limescale deposits within two to three weeks; a monthly wipe with white vinegar or a proprietary descaling product keeps fittings in good condition. The moderately hard north Shropshire Triassic supply at Market Drayton is an unremarkable but persistent domestic fact — rather like the Thursday market itself, reliably present every week.
