Líčkov is supplied through the network of Severočeské vodovody a kanalizace (SčVK), which draws on reservoirs and groundwater across northern Bohemia; the exact source for Líčkov is not confirmed here. Hardness is reported at 488.4 mg/L CaCO₃, so the water is very hard. Heavy limescale on kettles, heating elements and taps is to be expected, and a softener or scale inhibitor is worth considering.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/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).
