SINAC data from the Ministry of Health for September 2026 put Espartinas at 100 mg/L CaCO₃. The Seville metropolitan area is supplied mainly from reservoirs in the Sierra Norte and Huelva, such as Gergal, Cala and Aracena, operated by Emasesa; the ground is largely siliceous rock and the water tends to be soft. Limescale is hardly noticeable at this level, and most households do not need a softener.

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).
