Range across supply zones: 71–107 mg/L.
Brumunddal is served by Narud vannverk, run by Ringsaker kommune. The raw water is hard, about 10 °dH, and the plant softens it to 4 to 6 °dH before delivery, which is 71.4 to 107.1 mg/L CaCO₃; the figure here is the midpoint, 89.2 mg/L. The kommune's page does not say when the range was measured, and we have not checked the geology behind the hard raw water. Because the utility already softens the water, a home softener is usually not needed; occasional descaling of kettles is enough.
Norwegian waterworks report hardness in °dH or mg/L Ca; most supplies are very soft.

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).
