The hardness recorded in SINAC for Armilla is 119 mg/L CaCO₃, based on July 2026 data. In Granada province water comes from Sierra Nevada and limestone ranges as well as wells in the vega and basins, so hardness depends on which of those sources dominates. Scale builds up slowly; descaling the kettle and coffee machine now and then is usually enough.

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).
