Range across supply zones: 164–497 mg/L.
The hardness recorded in SINAC for Miguelturra is 330.5 mg/L CaCO₃, with readings from 164 to 497 mg/L, based on October 2026 data, so it varies a lot with the supply point and the blend at the time. In this part of Castilla-La Mancha the water comes from aquifers in limestone and gypsum and, in some cases, from pipelines from distant reservoirs, hence very high hardness. With water this hard, scale shortens the life of heating elements and hot-water pipes and often justifies treatment at home.

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).
