Range across supply zones: 70–73 mg/L.
Vitens supplies this area, mainly from groundwater, and the sandy ridges of the Veluwe and Utrecht Hills typically give water with comparatively little lime. The reported hardness is 71.4 mg/L CaCO₃, with values from 69.6 to 73.2 mg/L depending on the street. Scale shows on kettles and shower screens over time, but regular descaling usually keeps it manageable.
Dutch suppliers report °dH; most networks are softened centrally to 5.6–8.4 °dH.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
