What Makes Driffield's Water Unique?

Local geology and source profile

Yorkshire Water supplies Driffield (Great Driffield), the traditional market town at the head of the River Hull in the East Riding of Yorkshire — known as the 'Capital of the Yorkshire Wolds' and a key hub for the Wolds farming community since the Neolithic, with a famous Thursday cattle market — from Yorkshire Wolds Chalk aquifer supply blended with Pennine reservoir contribution in the East Riding distribution zone, treated at Tophill Low Water Treatment Works on the Hull valley near Beverley. At 178.5 mg/L (12.5°Clark), Driffield's water is hard — reflecting the significant Yorkshire Wolds Chalk groundwater contribution that characterises the East Riding chalk belt supply zone.

Driffield sits at the northern edge of the Yorkshire Wolds — the rolling chalk hills of East Yorkshire formed from the same Cretaceous Chalk that underlie the Lincolnshire and Norfolk chalk aquifers. Yorkshire Water draws on Wolds Chalk boreholes and the River Hull (which rises from chalk springs in the Wolds) to supply the East Riding chalk belt zone, producing 178.5 mg/L with TDS 467.4 mg/L for Driffield — moderately hard chalk water consistent with the Yorkshire Wolds chalk belt from Beverley through Market Weighton to Driffield.

At 178.5 mg/L, limescale is a persistent household concern in Driffield. Kettles benefit from descaling every three to four 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 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 chalk staining from accumulating permanently in this hard Yorkshire Wolds chalk supply zone at the head of the River Hull.

Geology & Source: Supplied by Yorkshire Water from Yorkshire Wolds Chalk aquifer blended with Pennine reservoir supply in the East Riding distribution zone — treated at Tophill Low Water Treatment Works — produces hard water at 178.5 mg/L (12.5°Clark).
