Bicske lies on the edge of the Vértes and Bakony hills, where karst water and wells in carbonate rock are the usual sources; the exact supply here is not confirmed. Limestone and dolomite of the Transdanubian Mountains release calcium and magnesium into the water, which is why supplies tied to this karst are among the hardest in Hungary; the 2024 national report lists Bicske at 379.3 mg/L CaCO₃ (very hard). Limescale forms fast on heating elements, taps and glass, which makes a softener or descale routine worthwhile.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.

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).
