Finnish waterworks use lake water, often treated or recharged through glacial esker deposits, or natural groundwater. The bedrock is mostly granite and gneiss, which usually gives soft water. The figure shown, 45.5 mg/L CaCO₃, is the median across 2 supply zones, which range from 19.6 to 71.4 mg/L, so it depends on which zone your street is in. Limescale is a minor issue here; a softener is unlikely to be necessary.
Finnish waterworks report hardness in °dH; most supplies are soft.
