Cross Hills Water Hardness & Quality Report (2026)

Yorkshire Water supplies Cross Hills, a village in the Craven district of North Yorkshire in the upper Aire Valley — a community at the foot of the Pennine moors between Skipton and Keighley, known as a gateway village to the Yorkshire Dales and sitting at the confluence of the ancient textile mill valleys that descend from the Millstone Grit uplands — from Pennine upland reservoirs in the Aire Valley and Craven catchment, treated at Barden Scale Water Treatment Works near Bolton Abbey. At 68.5 mg/L (4.8°Clark), Cross Hills' water is soft — consistent with the Millstone Grit and Carboniferous Shale bedrock of the South Pennine upland catchment that produces naturally soft, low-mineral reservoir water.

Cross Hills lies in the Craven Aire Valley at the foot of the Millstone Grit uplands where Yorkshire Water impounds soft Pennine runoff in the Aire catchment reservoir system above Skipton. The impermeable Millstone Grit (Carboniferous) and Bowland Shales of the South Pennine upland contribute minimal calcium to reservoir water, producing 68.5 mg/L with TDS 154.3 mg/L — soft water consistent with the upper Craven Aire Valley supply zone from Skipton through Cross Hills to Keighley in the same Yorkshire Water Barden Scale distribution corridor.

At 68.5 mg/L, Cross Hills' soft water is comfortable for domestic use with modest limescale demands. Descaling the kettle every two to three months is typically adequate. The combi-boiler benefits from a standard scale inhibitor as a sensible precaution. Washing-up liquid lathers well at everyday quantities. Taps and shower heads remain relatively scale-free with only occasional light maintenance. The soft Millstone Grit supply at Cross Hills is a characteristic of the upper Aire valley communities — the same soft water that ran through the textile mills on this stretch of the Pennine foothills for three centuries of woollen industry.
