The tap water in Chioggia comes from Veritas, which relies on groundwater wells and tops up with water from the Sile river treated at the Ca' Solaro plant; the wells tap carbonate-rich alluvial gravels. The reported figure is 217.0 mg/L CaCO₃, which counts as very hard water. Kettles, steam irons and dishwashers collect scale fast at this level, and a softener is a common answer.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
