Water is drawn from Sierra Morena and Guadalquivir reservoirs and from local aquifers. Official analyses put the water at 303 mg/L CaCO₃, very hard. Limestone and sedimentary rock dissolve plenty of calcium and magnesium, hence the high hardness. Scale on taps and shower screens is common, and water-heater elements foul sooner.

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).
