Gästrike Vatten publishes hardness per waterworks in Gävle kommun, and we show two zones: Gävle waterworks at 116.0 mg/L CaCO₃ and Valbo waterworks at 146.4 mg/L. The city figure of 131.2 mg/L is the median of the two. Which tap gets which water depends on the street, and the page does not give service areas, so the Valbo mapping is our inference. The table is undated; the detailed analyses were updated in May 2025.
Swedish municipalities report °dH; most surface-water supplies are soft.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
