WPWiK Wałbrzych prints three hardness ranges for the city in its second-quarter 2026 table: 8 to 10 °dH, 10 to 12 °dH and 17 to 19 °dH. The table layout does not let us pair each range with a named district reliably, so the 8 to 19 °dH shown here is the envelope of all three, not a city average. Neighbourhoods clearly get different water, so ask the utility which range applies to your street before sizing a softener. The utility does not say what sources or geology sit behind the gap.
Polish suppliers report total hardness in mg/L CaCO₃; the drinking-water regulation range is 60–500 mg/L.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
Estimates for planning, not a quote. Check your appliance manual for exact settings.
