Veritas publishes mean hardness for each municipality it serves, and for Noale the period October 2025 to March 2026 gives 28.5 °F (285.0 mg/L CaCO₃). That is very hard water. The table lists one zone for the town and does not name the sources behind it. At this level, limescale on taps, kettles and heating elements is likely, and descaling or a softener helps.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.

How much salt will you use for softening?
