Valle Umbra Servizi supplies Foligno, and the carbonate aquifers of the Umbrian Apennines are the traditional source of the area's spring water; the page we used does not give the current intakes. We hold a value of 243.7 mg/L CaCO₃ across 2 supply zones, with readings from 235.9 to 251.4 mg/L, which counts as very hard water (a 2022 figure that may have changed since). Values differ across the area, so check your own address before buying a softener; 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).
