This figure is over 3 years old; hardness may have changed.
In the Basel area, drinking water is drawn from groundwater in the Rhine and Birs plains, partly topped up with Rhine water infiltrated in the Hard forest, and the limestone of the Jura sets the hardness. Wasserversorgung Münchenstein reports a hardness of 277.5 mg/L CaCO₃. The figure dates from 2021 and may have changed. Scale forms quickly on heating elements and fittings, so a softener or strict descaling routine is worth considering.
In der Schweiz wird meist in °fH angegeben (1 °fH = 0,56 °dH).

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).
