Range across supply zones: 18–109 mg/L.
Yorkshire Water supplies Horbury from a network that blends reservoir, river and borehole sources, and the company links harder water in the east of the region to its borehole and groundwater supplies. Reported hardness is 21.9 mg/L CaCO₃, ranging from 17.5 to 109.3 mg/L between supply zones. Reservoir water from moorland catchments carries little dissolved calcium, which keeps the water soft; limescale is minimal at this level, so kettles and heaters stay largely clear and a softener would add little.
UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).

What it means at home

- Soap lathers easily; water does not dry skin or hair.
- Dishwasher: salt setting at minimum or off.
- No softener needed; a jug filter only changes taste.
How much salt will you use for softening?
No. Water this soft does not need softening.
Descale a coffee machine or kettle about every 6 months (typical manufacturer guidance for this hardness).
