Range across supply zones: 150–594 mg/L.
SINAC data from the Ministry of Health for September 2026 put Picassent at 460 mg/L CaCO₃, with readings from 150 to 594 mg/L, so it varies a lot with the supply point and the blend at the time. Tap water in Valencia province comes mainly from the Turia and Júcar basins and from local aquifers that run through limestone and marl rich in calcium and magnesium. This hardness forms limescale quickly in kettles, water heaters and washing machines; in a home, a softener is usually worth considering.

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).
