Range across supply zones: 173–193 mg/L.
Vitens supplies this part of eastern Netherlands mainly from groundwater, supplemented in places by bank-filtered river water from the IJssel and Vecht. The reported hardness is 189.2 mg/L CaCO₃, with values from 173.1 to 192.8 mg/L depending on the street. Scale forms quickly on heating elements and fittings, which makes a softener or a strict descaling routine worth considering.
Dutch suppliers report °dH; most networks are softened centrally to 5.6–8.4 °dH.

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).
