SMAT supplies Caselle Torinese mainly from deep groundwater, with smaller contributions from surface water and mountain springs; because the blend differs by area, hardness changes between towns on the same network. Published analyses give a typical value of 114.3 mg/L CaCO₃, which counts as moderately hard water. Scale forms slowly, so occasional descaling of the kettle is usually all it needs.
Italian utilities report °f (French degrees); D.Lgs. 31/2001 recommends 15–50 °f.

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).
