SINAC, the Ministry of Health's drinking-water register, reports 25 mg/L CaCO₃ for Meco, soft. Much of the Madrid region is supplied from sierra reservoirs on granite and gneiss, which keeps water soft, though the record does not say which source serves Meco. Scale is minimal; soft-water detergent doses are enough.
