PWiK Konin's average for the Konin-Kurów water station, first half of 2026, is 269 mg/L CaCO₃. This figure describes that station's output, so addresses fed from other parts of the network could differ slightly. The water is very hard, and scale in kettles and heaters is the everyday consequence.
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).
