The Bakony and Balaton Uplands are rich in karst water, which feeds much of Veszprém county; the exact source for Öcs is not confirmed here. 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; for Öcs the 2024 national report gives 381.0 mg/L CaCO₃ (very hard). Expect heavy limescale in kettles, boilers and on taps; descaling and a softener are worth considering.
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).
