Nearby towns on the same network vary widely, from 39.9 mg/L at Cumiana to 327.8 mg/L at Rivoli, so a neighbour's figure says little about yours. We have not confirmed which sources feed the town. At this level scale builds up slowly, and descaling a kettle now and then is usually enough.

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).
