Range across supply zones: 225–250 mg/L.
SINAC data from the Ministry of Health for July 2026 put Alhama de Murcia at 240 mg/L CaCO₃, with readings from 225 to 250 mg/L. Supply in the Murcia region relies on the Mancomunidad de los Canales del Taibilla, which blends water from the Taibilla river, the Tajo-Segura transfer and desalination plants, along with local sources. This is hard water: it leaves white marks on fittings and appliances need descaling fairly often.

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).
