Hale Water Hardness & Quality Report (2026)

South East Water supplies Hale, a village in the Waverley district of Surrey on the western fringe of the Surrey Hills near Farnham, from the Lower Greensand (Hythe Beds) aquifer and North Downs Chalk borehole sources in the west Surrey and Farnham supply zone, treated at regional west Surrey works. At 223.5 mg/L (15.7°Clark), Hale's water is hard — reflecting the calcareous Lower Greensand and chalk aquifer combination that characterises the South East Water supply in this part of the Surrey Hills fringe.

The Surrey Hills around Hale and Farnham are underlain by the Hythe Beds Lower Greensand and Upper Greensand (Cretaceous), calcareous sandstone formations containing calcium carbonate cements that contribute moderate to hard water chemistry from borehole abstraction. The North Downs Chalk escarpment to the north adds chalk aquifer water with higher calcium bicarbonate content to the supply blend. Together, these Cretaceous calcareous aquifer sources produce the hard 223.5 mg/L supply with TDS 552.2 mg/L that is characteristic of the South East Water supply zone in west Surrey between the chalk Downs and the Hampshire border.

At 223.5 mg/L, limescale is a consistent household challenge in Hale. Kettles should be descaled monthly to maintain element efficiency. The combi-boiler benefits from a fitted scale inhibitor and annual professional servicing. Washing-up liquid requires more product than in softer areas. Taps and shower heads develop visible white limescale within one to two weeks; a fortnightly wipe with white vinegar or a proprietary descaling solution keeps fittings clean and prevents hard-water staining from accumulating permanently on surfaces in this hard chalk and Greensand Surrey supply zone.
