Range across supply zones: 66–104 mg/L.

The tap water in Bradford comes from Yorkshire Water, which draws on moorland reservoirs in the west, rivers, and boreholes that are concentrated in the east of the region. Reported hardness is 91.3 mg/L CaCO₃, ranging from 66.1 to 104.1 mg/L between supply zones. The supply here blends softer reservoir water with harder borehole or river water; at this level scale forms steadily on heating elements and taps; a dishwasher salt setting and occasional descaling are sensible.

UK suppliers report mg/L CaCO₃ and often Clark degrees (1 °Clark = 14.25 mg/L).

What it means at home

How much salt will you use for softening?

Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.

Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).

5.3 gpg, equal to 5.1 °dH, 9.1 °fH or 91 mg/L calcium carbonate.

What dishwasher salt setting should I use in Bradford?

For 91 mg/L (5.1 °dH) check your manufacturer's table: level 2–3.

Do I need a water softener in Bradford?

Not essential; a scale inhibitor protects the heater cheaply.
